Method Summary
| `__init__(self, model, parent, name, check, commit, invalidErrorText, submodel, controllerStack)` (inherited from `InputHandler`)
| ``aggregateInvalid`(self, request, inputhandler, data)` By default we just pass this method call all the way up to the root Controller. (inherited from `InputHandler`)
| ``aggregateValid`(self, request, inputhandler, data)` By default we just pass the method calls all the way up to the root Controller. (inherited from `InputHandler`)
| ``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. (inherited from `InputHandler`)
| ``delEntity`(self, name)` Remove a static reference for 'name'. (inherited from `Resource`)
| `dispatchCheckResult(self, success, request, data)` (inherited from `InputHandler`)
| `domChanged(self, request, widget, node)` (inherited from `Controller`)
| ``entityConstraint`(self, entity)` A method that determines whether an entity may be added to me. (inherited from `ConfigCollection`)
| `gatheredControllers(self, v, d, request)` (inherited from `Controller`)
| ``getChild`(self, name, request)` Look for a factory method to create the object to handle the next segment of the URL. (inherited from `Controller`)
| ``getChildForRequest`(self, request)` (internal) Get a child of mine dependant on a particular request. (inherited from `Resource`)
| ``getChildWithDefault`(self, path, request)` Retrieve a static or dynamically generated child resource from me. (inherited from `Resource`)
| ``getDynamicChild`(self, name, request)` This method is called when getChild cannot find a matching wchild_* method in the Controller. (inherited from `Controller`)
| ``getDynamicEntity`(self, name, request)` Subclass this to generate an entity on demand. (inherited from `Resource`)
| ``getEntity`(self, name, request)` Retrieve an entity from me. (inherited from `Collection`)
| `getEntityType(self)` (inherited from `ConfigCollection`)
| ``getInput`(self, request)` Return the data associated with this handler from the request, if any. (inherited from `SingleValue`)
| `getNameType(self)` (inherited from `ConfigCollection`)
| ``getStaticEntity`(self, name)` Get an entity that was added to me using putEntity. (inherited from `Resource`)
| `getSubcontroller(self, request, node, model, controllerName)` (inherited from `Controller`)
| ``handle`(self, request)` By default, we don't do anything (inherited from `InputHandler`)
| ``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. (inherited from `InputHandler`)
| `importControllerLibrary(self, namespace)` (inherited from `Controller`)
| `initialize(self)` (inherited from `InputHandler`)
| ``listDynamicEntities`(self, request)` A list of all name, entity that I can generate on demand. (inherited from `Resource`)
| ``listDynamicNames`(self)` Retrieve a list of the names of entities that I store references to. (inherited from `Resource`)
| `listEntities(self)` (inherited from `Resource`)
| `listNames(self)` (inherited from `Resource`)
| ``listStaticEntities`(self)` Retrieve a list of all name, entity pairs that I store references to. (inherited from `Resource`)
| ``listStaticNames`(self)` Retrieve a list of the names of entities that I store references to. (inherited from `Resource`)
| `makeView(self, model, templateFile, parentCount)` (inherited from `Controller`)
| ``nameConstraint`(self, name)` A method that determines whether an entity may be added to me with a given name. (inherited from `Constrained`)
| ``pageRenderComplete`(self, request)` Override this to recieve notification when the view rendering process is complete. (inherited from `Controller`)
| `process(self, request, **kwargs)` (inherited from `Controller`)
| ``putChild`(self, path, child)` Register a static child. (inherited from `Resource`)
| ``putEntity`(self, name, entity)` Store an entity if it meets both constraints. (inherited from `Constrained`)
| `reallyPutEntity(self, name, entity)` (inherited from `Resource`)
| ``removeEntity`(self, name, request)` Remove an entity for 'name', based on the content of 'request'. (inherited from `Collection`)
| ``render`(self, request)` 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)` (inherited from `InputHandler`)
| `setSubcontrollerFactory(self, name, factory, setup)` (inherited from `Controller`)
| `setSubmodel(self, submodel)` (inherited from `Controller`)
| ``setUp`(self, request, *args)` (inherited from `Controller`)
| `setupControllerStack(self)` (inherited from `Controller`)
| `setView(self, view)` (inherited from `Controller`)
| ``storeEntity`(self, name, request)` Store an entity for 'name', based on the content of 'request'. (inherited from `Collection`)
| ``wchild_index`(self, request)` By default, we return ourself as the index. (inherited from `Controller`)

Method Details

### check(self, request, data)

Check whether the input in the request is valid for this handler and return a boolean indicating validity.

  Overrides:
    `twisted.web.woven.input.InputHandler.check` (inherited documentation)

### 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.

  Overrides:
    `twisted.web.woven.input.InputHandler.handleInvalid` (inherited documentation)
