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__: (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)
