Fixed #11740 -- Added extra detail on the behavior of ModelForms. Thanks to...

   ...     class Meta:

   ...         model = Article

.. note::

    If you explicitly instantiate a form field like this, Django assumes that you

    want to completely define its behavior; therefore, default attributes (such as 

    ``max_length`` or ``required``) are not drawn from the corresponding model. If 

    you want to maintain the behavior specified in the model, you must set the

    relevant arguments explicitly when declaring the form field.

    For example, if the ``Article`` model looks like this::

        class Article(models.Model):

            headline = models.CharField(max_length=200, null=True, blank=True, 

                                        help_text="Use puns liberally")

            content = models.TextField()

    and you want to do some custom validation for ``headline``, while keeping

    the ``blank`` and ``help_text`` values as specified, you might define 

    ``ArticleForm`` like this::

        class ArticleForm(ModelForm):

            headline = MyFormField(max_length=200, required=False, 

                                   help_text="Use puns liberally")

            class Meta:

                model = Article

    See the :ref:`form field documentation <ref-forms-fields>` for more information

    on fields and their arguments.
