DefaultHandler
An InputHandler is like a controller, but it operates on something
contained inside of self.model
instead of directly on
self.model
. For example, a Handler whose model
has been set to "foo"
will handle
self.model.foo
.
Method Summary | |

__init__(self,

| |
By default we just pass this method call all the way up to the root Controller. | |
By default we just pass the method calls all the way up to the root Controller. | |
Check whether the input in the request is valid for this handler and return a boolean indicating validity. | |
It has been determined that the input for the entire form is completely valid; it is now safe for all handlers to commit changes to the model. | |
Remove a static reference for 'name'. (inherited from Resource )
| |
dispatchCheckResult(self,
success,
request,
data)
| |
domChanged(self,
request,
widget,
node)
(inherited from Controller )
| |
A method that determines whether an entity may be added to me. (inherited from ConfigCollection )
| |
gatheredControllers(self,
v,
d,
request)
(inherited from Controller )
| |
Look for a factory method to create the object to handle the next segment of the URL. (inherited from Controller )
| |
(internal) Get a child of mine dependant on a particular request. (inherited from Resource )
| |
Retrieve a static or dynamically generated child resource from me. (inherited from Resource )
| |
This method is called when getChild cannot find a matching wchild_* method in the Controller. (inherited from Controller )
| |
Subclass this to generate an entity on demand. (inherited from Resource )
| |
Retrieve an entity from me. (inherited from Collection )
| |
getEntityType(self)
(inherited from ConfigCollection )
| |
Return the data associated with this handler from the request, if any. | |
getNameType(self)
(inherited from ConfigCollection )
| |
Get an entity that was added to me using putEntity. (inherited from Resource )
| |
getSubcontroller(self,
request,
node,
model,
controllerName)
(inherited from Controller )
| |
By default, we don't do anything | |
Once it has been determined that the input is invalid, we should tell our view to report this fact to the user. | |
It has been determined that the input for this handler is valid; however, that does not mean the entire form is valid. | |
importControllerLibrary(self,
namespace)
(inherited from Controller )
| |
initialize(self)
| |
A list of all name, entity that I can generate on demand. (inherited from Resource )
| |

| |
listEntities(self)
(inherited from Resource )
| |
listNames(self)
(inherited from Resource )
| |

| |
Retrieve a list of the names of entities that I store references to. (inherited from Resource )
| |
makeView(self,
model,
templateFile,
parentCount)
(inherited from Controller )
| |
A method that determines whether an entity may be added to me with a given name. (inherited from Constrained )
| |
Override this to recieve notification when the view rendering process is complete. (inherited from Controller )
| |
process(self,
request,
**kwargs)
(inherited from Controller )
| |
Register a static child. (inherited from Resource )
| |
Store an entity if it meets both constraints. (inherited from Constrained )
| |
reallyPutEntity(self,
name,
entity)
(inherited from Resource )
| |
Remove an entity for 'name', based on the content of 'request'. (inherited from Collection )
| |
Trigger any inputhandlers that were passed in to this Page, then delegate to the View for traversing the DOM. (inherited from Controller )
| |
renderView(self,
request)
(inherited from Controller )
| |
setNode(self,
node)
| |
setSubcontrollerFactory(self,
name,
factory,
setup)
(inherited from Controller )
| |
setSubmodel(self,
submodel)
(inherited from Controller )

(inherited from Controller )
| |
setupControllerStack(self)
(inherited from Controller )
| |
setView(self,
view)

Method Details |

aggregateInvalid(self, request, inputhandler, data)By default we just pass this method call all the way up to the root Controller. |
aggregateValid(self, request, inputhandler, data)By default we just pass the method calls all the way up to the root Controller. However, an intelligent InputHandler could override this and implement a state machine that waits for all data to be collected and then fires. |
check(self, request, data)Check whether the input in the request is valid for this handler and return a boolean indicating validity. |
commit(self, request, node, data)It has been determined that the input for the entire form is completely valid; it is now safe for all handlers to commit changes to the model. |
getInput(self, request)Return the data associated with this handler from the request, if any. |
handle(self, request)By default, we don't do anything
|
handleInvalid(self, request, data)Once it has been determined that the input is invalid, we should tell our view to report this fact to the user. |
handleValid(self, request, data)It has been determined that the input for this handler is valid; however, that does not mean the entire form is valid. |
