Method Details

__init__(self, *args, **kw)
(Constructor)

source code 
Initialize an input widget.

It accepts the following parameters (besides those listed at params):

name:
    Name of the input element. Will be the name of the variable
    the widget's input will be available at when submitted.

validator:
    Formencode validator that will validate and coerce the input
    this widget generates.

Overrides: object.__init__

adjust_value(self, value, **params)

source code 

Adjust the value sent to the template on display.

Overrides: base.Widget.adjust_value
(inherited documentation)

display(self, *args, **kw)

source code 
Display the widget in a Kid template.

Returns an elementtree node instance. If you need serialized output
in a string, call 'render' instead.

Probably you will not need to override or extend if inheriting from
Widget.

@params:

value   : The value to display in the widget.
**params: Extra parameters specific to the widget. All keyword params
          supplied will pass through the update_params method which
          will have a last chance to modify them before reaching the
          template.

Decorators:
  • @update_path
Overrides: base.Widget.display
(inherited documentation)

update_params(self, d)

source code 

Update the template parameters.

This method will have the last chance to update the variables sent to the template for the specific request. All parameters listed at class attribute 'params' will be available at the 'params' dict this method receives.

*Must* call super(MyWidget, self).update_params(params) cooperatively, unless, of course, your know what you're doing. Preferably this should be done before any actual work is done in the method.

Overrides: base.Widget.update_params
(inherited documentation)
