zeam.form.composed 1.3.2

Composed form support for zeam.form

This package let you defines forms containing other forms in zeam.form.base.

Example

Here a simple example. Let's define a setting form:

from zeam.form import composed, base
from zope.interface import Interface


class Setting(composed.ComposedForm):
    composed.context(Interface)

    label = u"Settings"

After, a module can add some mail settings on that screen:

class MailSetting(composed.SubForm):
    composed.context(MyApplication)
    composed.view(Setting)
    composed.order(99)

    label = u"Mail delivery settings"
    ...

And publications of that application could add some publication settings:

class PublicationSetting(composed.SubForm):
    composed.context(MyPublications)
    composed.view(Setting)
    composed.order(10)

    label = u"Publication settings"
    ...

Some default templates are included as well, but you can replace like you will do in zeam.form.base.

API

Classes

ComposedForm
This class define a form which able to contain other forms. It behave like a zeam.form.base Form, but does use its fields. A usefull method can give you back a given subform : getSubForm(identifier).
SubForm

This class represent a form which is contained inside a ComposedForm. This form behave exactly like a zeam.form.base Form to which you add:

  • a method available() which is called before anything else to know if the form shoud still be included in the ComposedForm.
  • a method getComposedForm() that gives you back the composed form in which this form is rendered.
SubFormGroup
This class let you group SubForm together. They are rendered within the group template, and prefixed by the group name. Like a SubForm they have an available() and a getComposedForm() method. It as well have a getSubForm(identifier) method.
