What is simplest way join __contains and __in?

Question

I am doing tag search function, user could observe a lot of tags, I get it all in one tuple, and now I would like to find all text which include at least one tag from the list.

Answer 1

Here you go:

filter = Q()
for t in tag_tuple: 
   filter = filter | Q(data__contains=t)
return text.objects.filter(filter)

A couple of tips:

• You should be naming your model classes with a capital (i.e. Text, not text)
• You may want __icontains instead if you're not worried about the case

Answer 2

I don't know Django, so I have no idea how to apply this filter, but it seems you want a function like this one:

def contains_one_of(tags, text):
    text = text.split()   # tags should match complete words, not partial words
    return any(t in text for t in tags)
