Method Details

rows(self)

source code

Return a list that contains ll.xist.Node objects and _xist_widget object. The nodes will be passed into the form as-is, the widgets will be initialized according to form usage, either with the values from the request+errors (on failed submits), values from the dbobject (display for a modification) or the defaults (for a new dbobject).

This default implementation will return all the widget_specs that are xist widgets from the dbclass.

widgets(self)

source code

Return a list of widgets in this form (i.e. extract the instances of widget from the result of (rows).

set_from_request(self, ignore_if_unset=True)

source code


Call the set_from_request() method of every widget. Catch validator
exceptions and process them into error messages using the
error_message() function. Return a dictionary as

   { 'param_name', [ error1, error2, ..., errorn ] }

An empty dict means successful submition ;-)

error_message(self, widget, exception)
