{{{
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

sites = models.ManyToManyField(Site)

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.
