Hi, three models that concern this issue are Photo, Tag, and PhotoTag.
Tag represents the model for all tags:
class PhotoTag( meta.Model ):
tid = meta.ForeignKey( Tag, core = True )
pid = meta.ForeignKey( Photo, core = True, verbose_name = "Photo
Tag", edit_
class META:
# following prevents identical tags on photo TODO: doesn't work
unique_together = ( ( "tid", "pid" ), )
Results in the following exception. Is unique_together not allowed on
ForeignKeys? If so, can anyone suggest a workaround?
File "/usr/lib/python2.3/site-packages/django/core/meta/__init__.py",
line 259,
in get_manipulator_fields
fields.extend(f.get_manipulator_fields(self.opts, manipulator,
change, name_p
refix=prefix, rel=True))
File "/usr/lib/python2.3/site-packages/django/core/meta/fields.py",
line 254, i
n get_manipulator_fields
params['validator_list'].append(getattr(manipulator, 'isUnique%s' %
'_'.join(
field_name_list)))
AttributeError: PhotoManipulatorAdd instance has no attribute
'isUniquetid_pid'
