Hi,
I need to exclude certain elements from a QuerySet. My models look
like this (simplified):
class Author(models.Model):
first_name = models.CharField(max_length=90, blank=True)
last_name = models.CharField(max_length=90, blank=True)
class Page(models.Model):
author = models.ForeignKey(Author)
mother = models.ForeignKey('self', blank=True, null=True,
related_name='child_set')
For each author, I need to get the set of pages representing all top-
level works by that author (so I don't need the chapters, sections
etc.). I guess the solution looks something:
def _get_top_level_children(self):
return self.page_set.exclude(author=mother.author)
top_level_children = property(_get_top_level_children)
Obviously, it does not work like this. How can I limit the queryset to
all entries where the 'author' object of a page does not match the
'author' object of the page's 'mother' object?
Kind regards,
Jan
