plone.autoform ============== plone.autoform ============== This package provides tools to construct z3c.form forms out of hints stored in tagged values on schema interfaces. A special form base class is used to set up the 'fields' and 'groups' properties on form instances. It also contains a 'display form' implementation that is compatible with Zope 2 page templates, and with some convenience features for rendering widgets in view mode. The tagged values are stored under a various keys. These can be found in the plone.autoform.interfaces module. They support: - changing a field to 'display' or 'hidden' mode - omitting fields - re-ordering fields relative to one another - placing fields into fieldsets (groups) - changing the widget of a field - displaying a field conditionally based on a permission There are several ways to set the form data: - Manually, by using setTaggedValue() on an interface. - By loading the schema from a plone.supermodel XML file and using the form: prefix - By using the grok directives in the plone.directives.form package. To use the automatic form setup, mix in the following base class in your forms: >>> from plone.autoform.form import AutoExtensibleForm and then provide the 'schema' (a schema interface) and optionally the 'additionalSchemata' (a list of schema interfaces) attributes on your form: >>> class MyForm(AutoExtensibleForm, form.EditForm): ... schema = IMySchema ... additionalSchemata = (ISchemaOne, ISchemaTwo,) ... ... # ... For dynamic forms, you could of course make 'schema' and 'additionalSchemata' into properties. To use the display form, create a view like: >>> from plone.autoform.view import WidgetsView >>> class MyView(WidgetsView): ... schema = IMySchema ... additionalSchemata = (ISchemaOne, ISchemaTwo,) ... ... # To render the form, do not override __call__(). Instead, either implement the render() method or set an 'index' attribute to a page template or other callable. See autoform.txt for details on how to use the form generation, view.txt for details on the widgets view, and supermodel.txt for information on the 'form' XML namespace in a plone.supermodel schema file. Changelog ========= 1.0b2 - 2009-07-12 ------------------ * Changed API methods and arguments to mixedCase to be more consistent with the rest of Zope. This is a non-backwards-compatible change. Our profuse apologies, but it's now or never. :-/ If you find that you get import errors or unknown keyword arguments in your code, please change names from foo_bar too fooBar, e.g. process_fields() becomes processFields(). Note in particular that the additional_schemata property is now called additionalSchemata. If you have implemented this property yourself, you will need to rename it!
