You’ll want to loop through the tag_list and apply a filter for each one.
tag_list = ['tag1', 'tag2', 'tag3'] base_qs = Design.objects.all() for t in tag_list: base_qs = base_qs.filter(tags__tag__contains=t)
This will give you results matching all tags, as your example indicated with
and. If in fact you needed
or instead, you will probably need Q objects.
Edit: I think I have what you’re looking for now.
tags = ['tag1', 'tag2', 'tag3'] q_objects = Q() # Create an empty Q object to start with for t in tags: q_objects |= Q(tags__tag__contains=t) # 'or' the Q objects together designs = Design.objects.filter(q_objects)
I tested this and it seems to work really well.
Edit 2: Credit to kezabelle in #django on Freenode for the initial idea.
