Hello, I'm stuck. Any help will be much appreciated.
I followed
http://www.djangoproject.com/documentation/models/m2m_intermediary/ to make
a
Many-to-many relationship via an intermediary table.
class LeftSide(models.Model):
:
class RightSide(models.Model):
:
class JoinTable(models.Model):
leftSide = models.ForeignKey(LeftSide,
edit_inline=models.TABULAR,
num_in_admin=3, core=True)
rightSide = models.ForeignKey(RightSide,
edit_inline=models.TABULAR,
num_in_admin=3,core=True)
reference_no = models.CharField(max_length=10, null=True, blank=True)
I can load the LeftSide in the admin, and choose to Change a record. I get
3 RightSide menu groups at the bottom. I can choose a RightSide to set as a
join. When I choose Save (any of the 3 save variations on the page) nothing
is saved.
There are two cases.
1) If the are already records in the join table for that LeftSide, then I
get an error when I save. {'jointable.0.id': [u'Join Table record with this
ID already exists.']} I didn't actually make any changes to that
association, so I don't know why it would complain.
2) If there are no join table records associated with the LeftSide, then
there is no error, but nothing is saved.
Am I doing something totally wrong here? Or is this a bug in the Admin
system?
