Question

I have a small problem and wondering if someone can help me out. I’m trying to do a check to see if the request.user is one of the user’s in the ManyToMany relationship table. Is there a way to accomplish this?

Example:

I want to check if the user is following the business page, and if they are, give them the ability to unfollow it and vice versa.

I have:

followers = models.ManyToManyField(User, related_name="Followers", null=True, blank=True)

Just wondering if theres a way to check the request.user.id against the followers table for that specific id.

Thanks everyone.

Answer 1

This “djangoic” way to do it:

if page.followers.filter(id=request.user.id).exists():
   do_something()

The more “pythonic” way, which is not recommended because it is very inefficient db wise:

if request_user in page.followers.all():
   do_something()

(This later one loads all users data into python, while the first one uses a db query)
