Once again Krylatij, I cant thank you enough for your help!
The content_types business has still been confusing me. Just to
confirm- i have a field in my super class :
content_type =
models.ForeignKey(ContentType,editable=False,null=True)
Working through your example I above:
> p = Page.objects.get(id='main')
> #here we get ContentType object for PageText or PageGallery
> content_type = ContentType.objects.get_by_id(p.contenttype_id)
I got to this point and
"ContentType.objects.get_by_id(p.contenttype_id)" returned nothing.
Somehow I was expecting some kind of magic to have filled in the
content_type field when the sub classes were created! I found this on
django snippets http://www.djangosnippets.org/snippets/1031/ and so
added the save function to my superclass, Page. :
def save(self):
if(not self.content_type):
self.content_type =
ContentType.objects.get_for_model(self.__class__)
self.save_base()
Im not sure if this was the kind of thing thats need or whether
there's an easier way of setting the content_type field in
subclasses.
