value::
[string or None] selected item in the list of options.
- addEntry(self, name, width=None, label=None, required=1, secret=0)
- Adds an entry control to the group. The entry control is obtained

be annotated as such.
secret::
[boolean] if true, the entry is a "password" entry (input
is obscured).
- addGroup(self, style='form')
- Adds a new "control group". This can be used to group a set of
controls together. The new group object is returned.
The new group object is obtained from the "form.group./style/"
property if defined, then the "form.group" property, and
finally @DefaultFormGroup is used by default.
parms::

[string] group display style. Generally accepted styles
are:
form::
Outer form.

from the "form.reset" property, a @DefaultResetButton instance
is used by default.
parms:
label::
[string or None] if not *None*, this is the label to be
placed on the button. This can also be obtained from the
value of the "form.reset.label" property, and "Reset" is
used by default.
- addSubmitButton(self, label=None)
- Adds a submit button to the group. The submmit button is obtained
from the "form.submit" property, a @DefaultSubmitButton instance
by default.
parms:
label::
[string or None] if not *None*, this is the label to be placed
on the button. This can also be obtained from the value
of the "form.submit.label" property, and "Done" is used
by default.
- setFields(self, fields)
- Sets the "fields" dictionary. This is used to lookup field
parameters that are not specified in the control methods.
parms:

output::
[file.write] output stream
indentContent::
[boolean] if true, multiline content is indented.
indent::
[int] number of characters to indent children
xhtml::
[boolean] if true, node and contents will be written in
XHTML instead of normal HTML.
- populate(self, valueDict)
- Populates this element and all nested elements from the value
dictionary.
If there is a key in valueDict matching a "name" attribute in this
element, sets the value of the element in a manner appropriate to the
element type.
This method is intended to allow you to populate an entire form from
the values in a query dictionary.
The value of the element is set using the @set() method. This
is what is generally overriden to vary the way control values are
defined.
- set(self, value)
- Sets the value of an element in the manner prescribed for the
element. This is really only relevant for form controls. The base
class version of this just sets the "value" attribute. Derived
classes should override as appropriate.
- writeTo(self, output, xhtml=0)
- Overrides @spug.web.xml.Element.writeTo() to provide an XHTML
parameter.
parms:
output::
[file.write]
xhtml::
[boolean] if true, node and contents will be written in
XHTML instead of normal HTML.
Methods inherited from web.xmlo.Element:
- __delitem__(self, accessor)
- __getitem__(self, accessor)
- Gets the specified attribute or content item, depending on whether
/accessor/ is a string (or tuple) or integer.
parms:
accessor::
[string or tuple<string, string> or int] If this is a string
or tuple, returns the associated attribute. If it is an
integer, returns the associated content item.
If this is a single string, returns the value of an attribute
in the global namespace. If it is a tuple of two strings,
the first string is a namespace URI.
If this is an integer, returns the value of a child element.
Interspersed text is ignored.
- __len__(self)
- Returns the number of content nodes in the element.
- __nonzero__(self)
- Because we define "len", we have to define this to always return
true so that all instances of @Element are considered "true".
- __setitem__(self, accessor, value)
- append(self, val)
- Appends a new element or text string to the contents of the element.
parms:
val::
[string or @Element]
- copy(self)
- Returns a deep copy of the element.
- deleteItem(self, index)
- Deletes the item at the specified index from the contents.
The more "correct" way to do this is through `__delitem__`:
i.e. "#del node[index]#". However, in Python 2.2.3, doing this
to a proxy (as return from the @getParent() method) causes
a *SystemError* due to a bug in the weak reference code.
- get(self, attr, default=None)
- getActualNamespace(self)
- Returns the actual namespace of the element name. The "actual
namespace" is the specified namespace if there is one,
it is the default namespace if there was no specified namespace.
- getAllChildren(self)
- Returns all child elements (list<@Element>). This actually returns
a reference to an internal list, so the caller should not modify
the value returned.
- getChild(self, namespace, name)
- Returns the first child with the given name. Returns None if no
such child exists.
parms:
namespace::
[string] namespace URI
name::
[string]

(tuple<string, string>). Note that the namespace is the
/specified namespace/, not the /actual namespace/.
- getName(self)
- Returns the simple unqualified name of the element.
- getNamespace(self, prefix)
- Returns the namespace URI for the given prefix. Returns None
if no such prefix is defined.
parms:
prefix::
[string] namespace prefix
- getParent(self)
- Returns the parent object (actually, a proxy to the parent object),
*None* if there is no parent.
- getPrefix(self, uri)
- Returns the namespace prefix for the given URI. Returns
None if no prefix is found for this URI.
parms:
uri::
[string] namespace URI to find the prefix for
- getValue(self)
- Returns the value of the element as one big string. This will
raise a ValueError if the element contains nested child elements.
- hasChildren(self)
- Returns true if the element has child elements.
- hasContents(self)
- Returns true if the element has contents (children or character
data).
- has_key(self, attr)
- Returns true if the element has the given attribute.
parms:
attr::
[string or tuple<string, string>] attribute to check for.

- Returns the index of the item within the contents list (an integer).
parms:
item::
[string or @Element]
- insert(self, index, val)
- iterate(self, explorer)
- Selectively iterates over the tree using the given explorer in
a depth-first traversal.
parms:
explorer::
[callable<any>] This object will be called for the node.
The value it returns indicates how the iteration proceeds.
The following return values are allowed:
EXPAND::
Iterate over the children of the node.
CONTINUE::
Do not iterate over the children of the node, continue
iteration with the next node in the parent's child list.
ABORT::
Abort iteration.
- setName = __setName(self, name)
- Sets the full name of the element.
parms:
name::
[tuple<string, string> or string] Either an unqualified name or
a tuple of namespace URI and local name.
- setValue = __setValue(self, newValue)
- Deletes all current contens of the element, and replaces it with
the new value.
parms:
newValue::
[string]
- setdefault(self, attr, default)
- strip(self, stripContent=0)
- Strips all "unnecessary" whitespace from the element and all nested
elements. Unncessary whitespace is whitespace between child
elements - when using XML for structured data representation,
this is usually just for formatting.
parms:
stripContent::
[boolean] if true, indicates that indentation of content
elements (nodes with no nested children
- stripEmptyContents(self)
- If the element contents consists of nothing but whitespace, deletes
all contents. Otherwise makes no changes to the element.
Returns true if contents were removed, false if not.

Methods inherited from web.xmlo.Element:
- __delitem__(self, accessor)
- __getitem__(self, accessor)
- Gets the specified attribute or content item, depending on whether
/accessor/ is a string (or tuple) or integer.
parms:
accessor::
[string or tuple<string, string> or int] If this is a string
or tuple, returns the associated attribute. If it is an
integer, returns the associated content item.
If this is a single string, returns the value of an attribute
in the global namespace. If it is a tuple of two strings,
the first string is a namespace URI.
If this is an integer, returns the value of a child element.
Interspersed text is ignored.
- __len__(self)
- Returns the number of content nodes in the element.
- __nonzero__(self)
- Because we define "len", we have to define this to always return
true so that all instances of @Element are considered "true".

parms:
val::
[string or @Element]

- deleteItem(self, index)
- Deletes the item at the specified index from the contents.
The more "correct" way to do this is through `__delitem__`:
i.e. "#del node[index]#". However, in Python 2.2.3, doing this
to a proxy (as return from the @getParent() method) causes
a *SystemError* due to a bug in the weak reference code.
- get(self, attr, default=None)

- Returns the actual namespace of the element name. The "actual
namespace" is the specified namespace if there is one,
it is the default namespace if there was no specified namespace.

- Returns all child elements (list<@Element>). This actually returns
a reference to an internal list, so the caller should not modify
the value returned.

None if no prefix is found for this URI.
parms:
uri::
[string] namespace URI to find the prefix for

The value it returns indicates how the iteration proceeds.
The following return values are allowed:
EXPAND::
Iterate over the children of the node.
CONTINUE::
Do not iterate over the children of the node, continue
iteration with the next node in the parent's child list.
ABORT::
Abort iteration.

the new value.
parms:
newValue::
[string]
- setdefault(self, attr, default)
- strip(self, stripContent=0)
- Strips all "unnecessary" whitespace from the element and all nested
elements. Unncessary whitespace is whitespace between child
elements - when using XML for structured data representation,
this is usually just for formatting.
parms:
stripContent::
[boolean] if true, indicates that indentation of content
elements (nodes with no nested children
- stripEmptyContents(self)
- If the element contents consists of nothing but whitespace, deletes
all contents. Otherwise makes no changes to the element.
Returns true if contents were removed, false if not.

- parms:
formNode::
[@FormNode] window to use as a source.

Methods inherited from FormModel:
- validate(self, request, errorList)
- Used to validate form submissions. This is called prior to
@submit(). If it returns false, there was at least
one validation error and @emitErrorPage() will be called instead.
This method iterates over the field set (as defined by the
/fields/ instance variable) and calls the @FieldInfo.validate()
method for each field in it.
May be overriden by derived classes, if so, you probably want
to call this method first.
parms:
request::
[@spugweb.Request] the initial request object
errorList::
[list<string or @spug.web.htmlo.HTMLElement>] This is an
output parameter: an empty list should be passed in.
If there are validation errors, they will be added to this
list.

The value of the element is set using the @set() method. This
is what is generally overriden to vary the way control values are

- set(self, value)
- Sets the value of an element in the manner prescribed for the
element. This is really only relevant for form controls. The base

is a good standard description of the error.
Public-vars:
fieldId::
[string] Name of the field that failed validation.

XHTML instead of normal HTML.
- populate(self, valueDict)
- Populates this element and all nested elements from the value
dictionary.
If there is a key in valueDict matching a "name" attribute in this
element, sets the value of the element in a manner appropriate to the
element type.
This method is intended to allow you to populate an entire form from
the values in a query dictionary.
The value of the element is set using the @set() method. This
is what is generally overriden to vary the way control values are
defined.
- set(self, value)
- Sets the value of an element in the manner prescribed for the
element. This is really only relevant for form controls. The base
class version of this just sets the "value" attribute. Derived

parameter.
parms:
output::
[file.write]

- Method resolution order:
- FormGroup
- FormControl
- web.htmlo.XNull
- web.htmlo.HTMLElement
- web.xmlo.Element
Methods defined here:
- __init__(self, request, *parms)
- addChoice(self, name, label=None, options=[], value=None)
- Adds a new "choice" control to the form.

[string] choice control name.
label::
[string or None] label associated with the choice
options::
[list<string>] list of options
value::
[string or None] selected item in the list of options.
- addControl(self, control)
- Adds a form control to the group.
Muet be implemented by derived class.
parms:
control::
[@FormControl] control to be added.
- addEntry(self, name, width=None, label=None, required=1, secret=0)
- Adds an entry control to the group. The entry control is obtained
from the "form.entry.required" or "form.entry.optional" method,
depending on whether the entry is required or optional.
parms:
name::
[string] entry name. This is the name by which the entry
control will be accessed.
width::
[int or None] if not *None*, this is the field width.
label::
[string or None] if specified, this is the entry field label.
required::
[boolean] if true, this entry is a required field, and will
be annotated as such.
secret::
[boolean] if true, the entry is a "password" entry (input
is obscured).
- addGroup(self, style='form')
- Adds a new "control group". This can be used to group a set of
controls together. The new group object is returned.
The new group object is obtained from the "form.group./style/"
property if defined, then the "form.group" property, and
finally @DefaultFormGroup is used by default.
parms::
style::
[string] group display style. Generally accepted styles
are:
form::
Outer form.
buttons::
button panel.
Other styles may be defined for richer forms.
- addResetButton(self, label=None)
- Adds a reset button to the group. The reset button is obtained
from the "form.reset" property, a @DefaultResetButton instance
is used by default.
parms:
label::
[string or None] if not *None*, this is the label to be
placed on the button. This can also be obtained from the
value of the "form.reset.label" property, and "Reset" is
used by default.
- addSubmitButton(self, label=None)
- Adds a submit button to the group. The submmit button is obtained
from the "form.submit" property, a @DefaultSubmitButton instance
by default.
parms:
label::
[string or None] if not *None*, this is the label to be placed
on the button. This can also be obtained from the value
of the "form.submit.label" property, and "Done" is used
by default.
- setFields(self, fields)
- Sets the "fields" dictionary. This is used to lookup field
parameters that are not specified in the control methods.
parms:
fields::
[dict<string, @FieldInfo>] Dictionary mapping field names
to field information objects.
Methods inherited from web.htmlo.HTMLElement:
- formatTo(self, output, indentContent=0, indent=2, xhtml=0)
- Overrides @spug.web.xml.Element.formatTo() to provide an XHTML
parameter.
parms:
output::
[file.write] output stream
indentContent::
[boolean] if true, multiline content is indented.
indent::
[int] number of characters to indent children
xhtml::
[boolean] if true, node and contents will be written in
XHTML instead of normal HTML.
- populate(self, valueDict)
- Populates this element and all nested elements from the value
dictionary.
If there is a key in valueDict matching a "name" attribute in this
element, sets the value of the element in a manner appropriate to the
element type.
This method is intended to allow you to populate an entire form from
the values in a query dictionary.
The value of the element is set using the @set() method. This
is what is generally overriden to vary the way control values are
defined.
- set(self, value)
- Sets the value of an element in the manner prescribed for the
element. This is really only relevant for form controls. The base
class version of this just sets the "value" attribute. Derived
classes should override as appropriate.
- writeTo(self, output, xhtml=0)
- Overrides @spug.web.xml.Element.writeTo() to provide an XHTML
parameter.
parms:
output::
[file.write]
xhtml::
[boolean] if true, node and contents will be written in
XHTML instead of normal HTML.
Methods inherited from web.xmlo.Element:
- __delitem__(self, accessor)
- __getitem__(self, accessor)
- Gets the specified attribute or content item, depending on whether
/accessor/ is a string (or tuple) or integer.
parms:
accessor::
[string or tuple<string, string> or int] If this is a string
or tuple, returns the associated attribute. If it is an
integer, returns the associated content item.
If this is a single string, returns the value of an attribute
in the global namespace. If it is a tuple of two strings,
the first string is a namespace URI.
If this is an integer, returns the value of a child element.
Interspersed text is ignored.
- __len__(self)
- Returns the number of content nodes in the element.
- __nonzero__(self)
- Because we define "len", we have to define this to always return
true so that all instances of @Element are considered "true".
- __setitem__(self, accessor, value)
- append(self, val)
- Appends a new element or text string to the contents of the element.
parms:
val::
[string or @Element]
- copy(self)
- Returns a deep copy of the element.
- deleteItem(self, index)
- Deletes the item at the specified index from the contents.
The more "correct" way to do this is through `__delitem__`:
i.e. "#del node[index]#". However, in Python 2.2.3, doing this
to a proxy (as return from the @getParent() method) causes
a *SystemError* due to a bug in the weak reference code.
- get(self, attr, default=None)
- getActualNamespace(self)
- Returns the actual namespace of the element name. The "actual
namespace" is the specified namespace if there is one,
it is the default namespace if there was no specified namespace.
- getAllChildren(self)
- Returns all child elements (list<@Element>). This actually returns
a reference to an internal list, so the caller should not modify
the value returned.
- getChild(self, namespace, name)
- Returns the first child with the given name. Returns None if no
such child exists.
parms:
namespace::
[string] namespace URI
name::
[string]
- getChildren(self, namespace, name)
- Returns all children with the given name.
parms:
namespace::
[string] namespace URI
name::
[name]
- getDefaultNamespace(self)
- Returns the default namespace URI for the node (string or None,
None means that the default namespace is the global namespace).
- getFullName(self)
- Returns the namespace and name of the of the element
(tuple<string, string>). Note that the namespace is the
/specified namespace/, not the /actual namespace/.
- getName(self)
- Returns the simple unqualified name of the element.
- getNamespace(self, prefix)
- Returns the namespace URI for the given prefix. Returns None
if no such prefix is defined.
parms:
prefix::
[string] namespace prefix
- getParent(self)
- Returns the parent object (actually, a proxy to the parent object),
*None* if there is no parent.
- getPrefix(self, uri)
- Returns the namespace prefix for the given URI. Returns
None if no prefix is found for this URI.
parms:
uri::
[string] namespace URI to find the prefix for
- getValue(self)
- Returns the value of the element as one big string. This will
raise a ValueError if the element contains nested child elements.
- hasChildren(self)
- Returns true if the element has child elements.
- hasContents(self)
- Returns true if the element has contents (children or character
data).
- has_key(self, attr)
- Returns true if the element has the given attribute.
parms:
attr::
[string or tuple<string, string>] attribute to check for.
- index(self, item)
- Returns the index of the item within the contents list (an integer).
parms:
item::
[string or @Element]
- insert(self, index, val)
- iterate(self, explorer)
- Selectively iterates over the tree using the given explorer in
a depth-first traversal.
parms:
explorer::
[callable<any>] This object will be called for the node.
The value it returns indicates how the iteration proceeds.
The following return values are allowed:
EXPAND::
Iterate over the children of the node.
CONTINUE::
Do not iterate over the children of the node, continue
iteration with the next node in the parent's child list.
ABORT::
Abort iteration.
- setName = __setName(self, name)
- Sets the full name of the element.
parms:
name::
[tuple<string, string> or string] Either an unqualified name or
a tuple of namespace URI and local name.
- setValue = __setValue(self, newValue)
- Deletes all current contens of the element, and replaces it with
the new value.
parms:
newValue::
[string]
- setdefault(self, attr, default)
- strip(self, stripContent=0)
- Strips all "unnecessary" whitespace from the element and all nested
elements. Unncessary whitespace is whitespace between child
elements - when using XML for structured data representation,
this is usually just for formatting.
parms:
stripContent::
[boolean] if true, indicates that indentation of content
elements (nodes with no nested children
- stripEmptyContents(self)
- If the element contents consists of nothing but whitespace, deletes
all contents. Otherwise makes no changes to the element.
Returns true if contents were removed, false if not.
This can used to "clean out" whitespace content after removing a
child element.

class FormModel |
|
Base class for Form "model objects" - these are objects that define
the data processing aspects of the form without any page
emission/rendering code.
Derived classes should provide a "fields" class variable associated
with a dict<string, @FieldInfo> mapping field names to field
information. |
|
Methods defined here:
- getFields(self, request)
- Returns the set of fields for the form. The "fields" instance
variable is returned by default.
Must be implemented by derived classes.
parms:
request::
[@spug.web.wof.Request]
- submit(self, request)
- Called when a form is submitted. All data processing should be
done here. This method must return an instance of @SubmissionResult.
Must be implemented by derived classes.
parms:
request::
[@spug.web.wof.Request]
- validate(self, request, errorList)
- Used to validate form submissions. This is called prior to
@submit(). If it returns false, there was at least
one validation error and @emitErrorPage() will be called instead.
This method iterates over the field set (as defined by the
/fields/ instance variable) and calls the @FieldInfo.validate()
method for each field in it.
May be overriden by derived classes, if so, you probably want
to call this method first.
parms:
request::
[@spugweb.Request] the initial request object
errorList::
[list<string or @spug.web.htmlo.HTMLElement>] This is an
output parameter: an empty list should be passed in.
If there are validation errors, they will be added to this
list.
|
class FormNode(web.wof.Node) |
|
Provides a nice framework for providing form processing.
There are two ways to work with this node, you can either create a
model object and specify it as the "form.model" property (thereby
allowing maximum flexibility in the separation of rendering and
business practice) or derive from this class and implement @submit()
(and optionally @validate()).
In any case, derived classes must override @emitSubmissionPage() and
@emitFormPage() to implement form submission and generation.
When these nodes are invoked with a remaining path of "submit",
the form submission routine is called. When invoked with any
other remaining path, the form display routine is called.
Instances of derived classes should have a "fields" variable which
should be a dictionary implementation mapping field names
to @FieldInfo instances defining the field information.
Properties:
form.model::
[@FormModel] model object for the form. |
|
Methods defined here:
- delegateSubmissionPage(self, request, response, actionsCompleted)
- Delegates emission of the submission page to the URL specified
in the #`_lastPage`# query parm (if any). Returns true if the
request was successfully delegated.
parms:
request::
[@wof.Request]
response::
[@wof.Response]
actionsCompleted::
[list<@htmlo.Element or string>] list of actions to pass on
to the delegate page through the "form.actionsCompleted"
local request key.
- emitErrorPage(self, request, response, errorList)
- Generates an error page suitable for displaying the validation
errors for the form. Creates the page from an unordered list
of validation errors followed by the return value of
@getFormElem() wrapped in the value of the "form.wrapper"
property.
May be overriden by derived classes: if not, @getFormElem() must
be overriden.
- emitFormPage(self, request, response)
- Generates the form. Creates the page from the return value
of @getFormElem() wrapped in the value of the "wrapper"
property.
May be overriden by derived classes: if not, @getFormElem() must
be overriden.
- emitPage(self, request, response)
- emitSimpleSubmissionPage(self, request, response, actionsCompleted)
- Utility method which can be used to display a simple message
acknowledging the submission of a form for pages that don't really
have anything to display and no "_lastPage" field as been passed.
parms:
request::
[@wof.Request]
response::
[@wof.Response]
actionsCompleted::
[list<string or @htmlo.Element>] list of actions completed
for display.
- emitSubmissionPage(self, request, response, submitResult)
- Processes form parameters and generates response page. Default
version of this method calls @delegateSubmissionPage() to
attempt to delegate processing, and just displays "Request
Submitted" if the request was not delegated.
May be overriden by derived class.
parms:
request::
[@wof.Request]
response::
[@wof.Response]
submitResult::
[@SubmissionResult] value returned from the @FormModel.submit()
method.
- getCompleteFormElem(self, request)
- Utility method which returns the form element (result of
@getFormElem()) and adds the "method" and "action" (submit path)
attributes to the form (and the `_lastPage` hidden input field,
if there is a `_lastPage` attribute).
Compound pages wishing to include a form should use this instead of
calling @getFormElem() directly.
parms:
request::
[@Request]
- getContentType(self, request)
- getFields(self, request)
- See @FormModel.submit() for docs.
Derived classes not defining their own model objects may override
this.
- getFormElem(self, request)
- Returns the form element - this is the top level element used to
contain the form.
Must be implemented by derived classes unless both @emitFormPage() and
@emitErrorPage() are implemented and this method is not used by them.
- isStatic(self, request)
- submit(self, request)
- See @FormModel.submit() for docs.
Derived classes not defining their own model object may override this.
- validate(self, request, errorList)
- See @FormModel.validate() for docs.
Derived classes may override this and call the base class
version of the function.
Methods inherited from web.wof.Node:
- __getitem__(self, property)
- __init__(self, **properties)
- __setitem__(self, property, val)
- buildCache(self, context, targetBaseURL, dynamicBaseURL=None)
- Recursive function to build the cache for the node and its
descendents.
parms:
context::
[@NodeContext] node invocation context.
targetBaseURL::
[string] base URL of the target location. This will be the
base of all absolute URLs used to refer to other static pages
within the tree. You need not specify the full URL: the
path portion (starting from the first slash after host name
and optional port number) is normally adequate.
dynamicBaseURL::
[string or None] base URL of all dynamic web pages in the tree.
This will be the base of all absolute URLs referred to by
static pages. If *None*, attempting to link to a dynamic
node from a static node will cause an error.
- emitPageInContext(self, request, response)
- This is a special purpose function to allow page delegation.
Emits the page in its "native execution context".
- fixExtension(self, request, pathName)
- Fixes the extension of /pathName/ so that it corresponds to the
content type of the node.
- getCachePath(self, request)
- Returns the cache path for the node. By default this is constructed
from the cache path for the node with the extension for its content
type appended.
May be overriden by derived classes.
- getDependentsTimestamp(self, request)
- Returns the timestamp of the newest dependent (float).
This method returns the timestamp based purely upon the timestamps
of the modules of the classes (immediate and ancestor) of the
current page node.
Derived classes should override it if they have dependencies on
information that is outside of the scope of these modules, and
should call the base class form of the method to obtain
the "code timestamp" for comparison.
- getNodeAtPath(self, path, parentContext=None, name='')
- Returns a tuple consisting of the node dereferenced by the given
path, the node context and the remainder of the path info
(tuple<@Node, @NodeContext, string>).
parms:
path::
[string] full path
parentContext::
[@NodeContext] the parent's context
name::
[string] the name that the node was referenced under (part of
the path)
- getPage(self, request, response)
- Gets the content of the page identified in the request and
writes it into the response. If the request is for a static
page, the cache is refreshed and the response is written from the
cache. If not, @emitPage() is called directly and is expected
to write a page of content type specified by the @getContentType()
method.
- getPageInContext(self, request, response)
- Gets the page in its "native execution context" (for now, just
the current working directory, but eventually this could have
more meaning than that).
- getSourcePath(self)
- Returns the node's "source path". This is not context dependent.
- has_key(self, property)
- isLocalRoot(self, treeName)
- Returns true if the node is the local root for the given tree name.
parms:
treeName::
[string] tree to check for. A value of '.cur' always
returns true.
- load(self)
- "Loads" the node - this causes the node object to be fully
initialized. A node must be loaded prior to performing any other
operations on it.
Loading is disassociated from intialization so that we don't have
to build the entire node tree during initialization.
Derived classes should not override this: override @_load() instead.
- refreshCache(self, request, cachePath)
- Refreshes the cached image of a cacheable node. If the node is out
of date with its dependents (@getDependentsTimestamp() should
return the timestamp of the newest dependent) this calls
@emitPage() with a modified request that writes to the cache file.
parms:
request::
[@Request]
cachePath::
[string] cache file name
- setLocalRoot(self, treeName)
- This method defines a node as a "local root". Local roots allow
URLs to be constructed relative to a known base. A local root
parameter can be specified in @Request.getAbsolutePath().
parms:
treeName::
[string] tree that the node is a local root for. Values
beginning with '.' are reserved and _should not be used_.
|
class SubmissionResult |
|
Abstract base class for objects returned from the @FormModel.submit()
method. |
|
Methods defined here:
- getActionsCompleted(self)
- Returns a list of actions completed (list<string or @htmlo.Element>)
identifying the actions completed by the form.
- getErrors(self)
- Returns all of the errors as a list of strings or @FieldError
instances (list<string or @FieldError>). Returns *None* if
no errors occurred.
Must be implemented by derived class.
- getResult(self)
- Returns the result object (which can be of any type).
The caller should first have checked for errors with @getErrors().
Must be implemented by derived class.

to the delegate page through the "form.actionsCompleted"
local request key.
- emitErrorPage(self, request, response, errorList)
- Generates an error page suitable for displaying the validation
errors for the form. Creates the page from an unordered list
of validation errors followed by the return value of

property.
May be overriden by derived classes: if not, @getFormElem() must
be overriden.
- emitFormPage(self, request, response)
- Generates the form. Creates the page from the return value
of @getFormElem() wrapped in the value of the "wrapper"
