I want to have a models.py like this,
class PageRevision(models.Model):
"""Stores a specific revision of the page"""
text = models.TextField()
revision_for = models.ForeignKey(Page, related_name =
'revision_for')
class Page(models.Model):
"""Stores the latest page, the page which needs to be displayed to
the user."""
title = models.SlugField(unique = True, max_length = 100)
current_revision = models.ForeignKey(PageRevision, related_name =
'main')
current_disc_rev = models.ForeignKey(PageRevision, related_name =
'discussion', blank = True, null = True)
This line gives me an error,
revision_for = models.ForeignKey(Page, related_name = 'revision_for')
as NameError: name 'Page' is not defined, obviously because page is
defined later in the file. I can not put PageRevision later as Page
class refers to that. How can I acieve this?
(I need this type of model as PageREvision is a detail table for Page,
so it needs to have a Foreign key to Page. But page also needs to keep
track of its latest revision, and so needs a foreign key to
PageREvision! I guess I can achieve what I want to do by having two
boolen fields in PageRevision to track its latest status, but this
seems a cleaner model.)
