How to do a less than or equal to filter in Django queryset?

Question

I am attempting to filter users by a custom field in each users profile called profile. This field is called level and is an integer between 0-3.

If I filter using equals, I get a list of users with the chosen level as expected:

user_list = User.objects.filter(userprofile__level = 0)

When I try to filter using less than:

user_list = User.objects.filter(userprofile__level < 3)

I get the error:

global name ‘userprofile__level’ is not defined

Is there a way to filter by < or >, or am I barking up the wrong tree.

@BéresBotond Although the docs look great – the structuring and layout is so poor that without a direct link, they are all but useless — RunLoop

Less than or equal:

User.objects.filter(userprofile__level__lte=0)

Greater than or equal:

User.objects.filter(userprofile__level__gte=0)

Likewise, lt for less than and gt for greater than. You can find them all in the documentation.

Wow, that was fast :). This works great for less than or equal, but how about just less than? (userprofile__level__lt=3) doesn’t seem to work

It does; but in any case, you can also do exclude(__gte) instead of filter(__lt).

And do NOT forget that there are two __ underlines

Im getting this error–> {FieldError}Unsupported lookup ‘level’ for AutoField or join on the field not permitted.

question, what does =0 mean here? false? true?
