{{{
class FlatPage(models.Model):
url = models.CharField(_('URL'), max_length=100, db_index=True)
title = models.CharField(_('title'), max_length=200)
content = models.TextField(_('content'), blank=True)
enable_comments = models.BooleanField(_('enable comments'))
template_name = models.CharField(_('template name'), max_length=70,
blank=True,
help_text=_("Example: 'flatpages/contact_page.html'.
If this isn't provided, the system will use 'flatpages/default.html'."))
registration_required = models.BooleanField(_('registration
required'), help_text=_("If this is checked, only logged-in users will be
able to view the page."))
sites = models.ManyToManyField(Site)
class SubFlatPage(models.Model):
url = models.CharField(_('URL'), max_length=100, db_index=True)
title = models.CharField(_('title'), max_length=200)
content = models.TextField(_('content'), blank=True)
sites = models.ManyToManyField(Site)

Using a subset of fields on the model (abstract=True OR abstract=False )

[http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#using-a
-subset-of-fields-on-the-form]
# Use the fields attribute of the Model's inner Meta class. This
attribute, if given, should be a list of field names to include in the
SubModel.
# Use the exclude attribute of the Model's inner Meta class. This
attribute, if given, should be a list of field names to exclude from the
SubModel.
# Can append a little other fields.
