Django: Elegant way to lookup a non-empty string

Question

I have a model Chair with a blank-able CharField called wood_type .

I want to filter all the chairs with a wood_type which is not '' .

What's an elegant way to do it with Django?

I can think of this:

Chair.objects.filter(~django.db.models.Q(wood_type=''))

Or this:

Chair.objects.filter(wood_type__regex='(.|\n)+')

But they're ugly as hell. Is there a more elegant way?

Answer 1

Chair.objects.exclude(wood_type='')应该可以解决问题。

Answer 2

排除空字符串

Chair.objects.exclude(wood_type='')
