pass additional variable form views.py to filters.py

[mgausvoe]

to show the specific possible choices of a dataset I need to pass an additional parameter (here my_variable) form the views.py to filters.py:

views.py:

my_variable= 123

f = CompanyDataFilter(queryset=CompanyDataView.objects.using('extern_db').filter(company_id=primary))

filters.py

class CompanyDataFilter(django_filters.FilterSet):
....

sector = django_filters.ModelChoiceFilter(queryset=CompanyDataView.objects.values_list('sector', flat=True).using('extern_db').distinct().filter(company_id=my_variable),empty_label='Sector', help_text='Search Sector')

....

but I have no idea how to manage it to pass my_variable from the views.py to the filters.py

Any idea?

Thanks a lot in advance!

I am searching for a similar solution as well. I need to pass additional context to the filter class.
In my case I use django rest framework.
What I can suggest is to add context attribute to the filter class which can be passed by a get_filter_context method in the view. Pretty similar to how context is passed to the serializer - http://www.django-rest-framework.org/api-guide/serializers/#including-extra-context
