"Django-filter" Is it possible to use FilterClass(FilterSet) MultipleChoiceFilter within ViewSet methods? Django 1.11, Python 2.7
I have my class ClassFilter(FilterSet) with some of the Filters fx. MultipleChoiceFilter, ModelMultipleChoiceFilter etc. in it: class ClassFilter(FilterSet): something_severity = MultipleChoiceFilter(choices=Something.SEVERITY_CHOICES, method='something_severity_filter', widget=CSVWidget) def something_severity_filter(self, queryset, name, severities): if severities: queryset = queryset.filter(something_state=Something.STATE_SOMETHING) ... return queryset class Meta: model = Something fields = [] It works perfect when it comes to filtering endpoints. It is assigned to the class like: class ClassViewSet(mixins....., DefaultApiViewSet): filter_class = ClassFilter by having filter_class = ClassFilter. Everything works just fine but now I am in in doubts if I may use the ClassFilter MultipleChoiceFilter within ClassViewSet methods. This means by executing POST method in ClassViewSet, I want to get the MultipleChoiceFilter from FilterClass to filter on my method by getting it as SomethingFilter.get_filters() method @action(detail=False, methods=['post']) def something_update(self, req): ... all_filters = SomethingFilter.get_filters() for serializer_filter in serializer_filters: for filter in all_filters: if(serializer_filter == filter): f = all_filters[filter] Now the f is a filter which I require so that is MultipleChoiceFilter. But when I try to filter with that filter it throws an error. f.filter(queryset, [('LOW')]) #filter the queryset with the filter based on LOW choice Throws: assertionError: Filter 'something_severity' must have a parent FilterSet to find '.something_severity_filter()' In documentation for django-filter it is exactly line: … -

Problem in deploying Django website on Cyber Panel
I have deployed the Django website on openlite server and cyberpanel. According to the documentation of the cyberpanel, there is no requirement to run the server manually. The default page of cyberpanel will be removed automatically once the Django website will be there. But in my case, that default page is still there. As this is not working, I tried it by executing the following command: python manage.py runserver example.com:8000 After this, the website is working only on port 8000 i.e. "https://example.com:8000", but not on "https://example.com". I have tried configuring all the settings in settings.py like setting the allowed host to ["*"] and also configuring the configurations of vhost in cyberpanel but still it is not working. Can anyone help please ? -
