How to do a not equal in Django queryset filtering

Question

Hii Team,

In Django model QuerySets, I see that there is a __gt and __lt for comparitive values, but is there a __ne/!=/<> (not equals?)

I want to filter out using a not equals:

Example:

Model:
    bool a;
    int x;

I want

results = Model.objects.exclude(a=true, x!=5)

The != is not correct syntax. I tried __ne, <>.

I ended up using:

results = Model.objects.exclude(a=true, x__lt=5).exclude(a=true, x__gt=5)

Any help?

Hello @kartik,

Your query appears to have a double negative, you want to exclude all rows where x is not 5, so in other words you want to include all rows where x IS 5. I believe this will do the trick.

results = Model.objects.filter(x=5).exclude(a=true)

To answer your specific question, there is no "not equal to" but that's probably because django has both "filter" and "exclude" methods available so you can always just switch the logic round to get the desired result.

Hope it helps!!

Thank You!!
