I have a custom mode that in inherits from the Mezzanine Page model, let's
just call it PressRoom. I have no problem adding a new PressRoom page in
the admin interface. I tried dragging the page and making it a child of one
of the top level pages. Then I tried to delete the page and it threw this
error:
IntegrityError at /admin/pages/page/3/delete/(1451, 'Cannot delete or update a
parent row: a foreign key constraint fails (`main_django`.`main_pressroom`,
CONSTRAINT `page_ptr_id_refs_id_61318436` FOREIGN KEY (`page_ptr_id`)
REFERENCES `pages_page` (`id`))')
I have a custom mode that in inherits from the Mezzanine Page model:
class PressRoom(Page):
rel_canonical = models.CharField(blank=True, max_length=256)
pressreleases = PressRelease.objects.all()
Here is the corresponding admin.py code:
class PressRoomAdmin(reversion.VersionAdmin, PageAuthGroupAdminMixin,
PageAdmin):
model = appdmodels.PressRoom
fieldsets = (
(None, {
'fields': (
'title',
'status',
'publish_date',
'in_menus',
'login_required',
),
}),
('Meta', {
'fields' : (
'_meta_title',
'slug',
'rel_canonical',
'description',
'keywords',
'gen_description',
'in_sitemap',
),
}),
)
admin.site.register(appdmodels.PressRoom, PressRoomAdmin)
I have a feeling it has to do with the page_ptr_id not being updated, but
I'm not sure what and where to update. Or perhaps I broke some convention
and now it's throwing errors. Any help would be appreciated.
