Missing import django_filters in docs code snippet

[kjschiroo]

In Adding a FilterSet with filter class the code snippet appears to be missing an import django_filters

Hi.

I think you made the PR against your own repo. Oops.

More though, I don’t think the import is missing. It’s the line below the one you added.

Yep, I screwed up the PR. I see it now, you aren't necessarily missing an import statement, but something does need to change. Exploring in the shell:

In [1]: from django_filters import rest_framework as filters

In [2]: min_price = django_filters.NumberFilter(name="price", lookup_expr='gte')
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

----> 1 min_price = django_filters.NumberFilter(name="price", lookup_expr='gte')

NameError: name 'django_filters' is not defined

In [3]: min_price = filters.NumberFilter(name="price", lookup_expr='gte')
