Are you sure? I just tested it (using the definitions from the
"Simplifying Association Objects" section) with the following at the
bottom:
if __name__ == '__main__':
user = User('log')
user.keywords = [Keyword('one'), Keyword('two')]
for uk in user.user_keywords:
print uk, uk.
Yes.
However doing so:
user.keywords = [ Keyword('one'), Keyword('two') ]
...will create UserKeywords with user unset. This is the problem.

association proxy docs say that something like:
kw = Keyword('one')
user.keywords.append(kw)
has the same effect as:
kw = Keyword('one')
uk =
Hi,
I just noticed that User.groups relationship is not needed at all (it was a

I already use *AssociationProxy* pattern in order to have relations like
*User.A_groups,
User.B_group**s, USer.C_gr
Glad you've figured it out. This is touched on briefly in the docs, in
the note at the bottom of:
http://docs.sqlalchemy.org/en/rel_0_9/orm/basic_relationships.html#association-object
As an alternative to making User.groups a relationship, you could also
consider using the Association Proxy exten
Hi,
Adding viewonly=True on User.groups relationship solved the issue.
cheers!
