Providing initial data for the forms

====================================

.. attribute:: FormWizard.initial

    Initial data for a wizard's :class:`~django.forms.Form` objects can be

    provided using the optional :attr:`~FormWizard.initial` keyword argument.

    This argument should be a dictionary mapping a step to a dictionary

    containing the initial data for that step. The dictionary of initial data

    will be passed along to the constructor of the step's

    :class:`~django.forms.Form`::

        >>> from testapp.forms import ContactForm1, ContactForm2, ContactWizard

        >>> initial = {

        ...     0: {'subject': 'Hello', 'sender': 'user@example.com'},

        ...     1: {'message': 'Hi there!'}

        ... }

        >>> wiz = ContactWizard([ContactForm1, ContactForm2], initial=initial)

        >>> form1 = wiz.get_form(0)

        >>> form2 = wiz.get_form(1)

        >>> form1.initial

        {'sender': 'user@example.com', 'subject': 'Hello'}

        >>> form2.initial

        {'message': 'Hi there!'}
