Plone Formgen Fields using Master Select Widgets

Project description

Products.PFGMasterSelect

An add-on field for PloneFormGen using the MasterSelect widget.

How to use

Please note that PloneFormGen’s QuickEdit mode does not work (yet) for this add-on.

After installing this product you can create the Master Select and Master Multiselect fields via the “Add new…” menu in a PloneFormGen form. Both fields allow you to specify a default value and the options available as the common selection field does.

Additionally it provides a configuration table that contains the MasterSelect configuration (see also MasterSelectWidget documentation for more detail):

name (required)
The target field’s name
action (required)
The action to be applied on the target field. The options are * show/enable: Show/Enable the target field only if toggle_method evaluates to True or the field’s value is in hide_value * hide/disable: Hide/disable the target field if toggle_method evaluates to True or the field’s value is in hide_values * value: Set the target field’s value to the result of the vocab_method * vocabulary: Set the target field’s vocabulary to the result of the vocab_method
vocab_method
A python expression evaluating to a single value or collection. The currently set value (MasterSelect) or values (MasterMultiSelect) are available via value and values respectively. Example: Set the vocabulary of a selection field using ['xyz' + v for v in values]
toggle_method
A python expression evaluating to a boolean value. This method takes precedence to hide_values. The currently set value (MasterSelect) or values (MasterMultiSelect) are available via value and values respectively. Example: Hide a field if the selected value has length 5 or equals foo using len(value) == 5 or value == 'foo'
hide_values
The values that show/hide/enable/disable operate on Example: Hide a field if the selected value is a or b using a,b
