python - Querying for Multiple ManyToMany Fields -


i have model, entry, manytomany field:

tags = models.manytomanyfield(tag)

the tag model simple:

class tag(models.model):      name = models.charfield(max_length=25)      def __unicode__(self):         return self.name

i want create function, getentrybytags takes list of tag names , returns entry has tags. if knew number of tags , names of each, trivial:

entry.objects.filter(tags__name="tech").filter(tags__name="music").filter(tags__name="other")

but since going based on user input , tags number variable, i'm not sure how proceed. how iterate on multiple item list object contains each of manytomany objects names represented in list?

you can try,

from django.db.models.query_utils import q  tag_name_list = xxx # dynamic tag name list based on user input  query_list = [q(tags__name=tag_name) tag_name in tag_name_list] query_set = entry.objects query in query_list:     query_set = query_set.filter(query) return query_set
