Calling filter with a variable for field name

Question

Is there a way to call filter on a queryset where one of the fieldnames is a variable?

For example I have something like:

models.py

Answer 1

Playlist.objects.filter(**{field_name: v})

Answer 2

To use field name string with icontains.

Try this

field_name = 'video'
field_name_icontains = field_name + '__icontains'
Playlist.objects.filter(**{field_name_icontains: v})
