Hi,
i've defined the following relations:
db.define_table('users_dictionaries',
Field('user_id', db.auth_user, requires =
IS_IN_DB(db,'auth_user.id', db.auth_user._format)),
Field('dictionary_id', db.dictionary,
requires=IS_IN_DB(db,'dictionary.id',db.dictionary._format)),
)
db.define_table('users_categories',
Field('user_id', db.auth_user, requires =
IS_IN_DB(db,'auth_user.id', db.auth_user._format)),
Field('category_id', db.category,
requires=IS_IN_DB(db,'category.id',db.category._format)),
)
i then created a grid=SQLFORM.smartgrid(db.auth_user) and i can see the
many-to-many relations i can navigate on them but when i try to add one
i get:
Traceback(most recent call last):

TypeError:'NoneType'objectis notcallable
The problem is rep() being None but the documentation about
field.represent says:
|represent| can be None or can point to a function that takes a field value
and returns an alternate representation for the field value.
So it can be None or a function.... how can i fix it?
