Description
When using a many 2 many relation ship with 'though' parameter, the DB is returning duplicates when several relations exists for the same pair of objects.
I have the following relations :
tag 1 user 1 -----> article 1 tag 2 user 1 -----> article 1
Expected behavior :
user = User.objects.get(pk=1) print user.article.all() [<Article: 1>]
Observed behavior
user = User.objects.get(pk=1) print user.article.all() [<Article: 1>, <Article: 1>]
