default values, assigning groups to employee users, and installing modules.
|

To make such a 'settings' wizard, define a model like::

_name = 'sale.config.prefs'

}

* For a field like 'default_XXX', ``execute`` sets the (global) default value of
|
||||
the field 'XXX' in the model named by ``default_model`` to the field's value.
|
||||
|
||||
* For a boolean field like 'group_XXX', ``execute`` adds or removes the group given
|
||||
by its XML id to the implied groups of Employee, depending on the field's value.
|
||||
|
||||
* For a boolean field like 'module_XXX', ``execute`` triggers the immediate
|
||||
installation of the module named 'XXX' if the field has value ``True``.
|
||||
|
||||
* For other fields, the method ``execute`` only record their value for future
|
||||
invocations of the wizard. Override the method to define their effect.
