Filter in Django Rest Framework - django-rest-framework

Question

I'm new in DRF: ¿Can I create a filter in a function in Django Rest Framework, not created it in a Class, for use in a view? I'm trying a filter for search by: document and document_type.
Ty
My code:
#model
class Account(models.Model):
'''Modelo para la gestión de cuentas'''
document_type = models.CharField('Tipo documento', null=True, max_length=20, choices=DOCUMENT_TYPE)
document = models.CharField('Documento',null=True, max_length=18)
first_name = models.CharField('Nombres / razón social',null=True, max_length=100)
last_name = models.CharField('Apellidos', null=True, max_length=100)
phone = models.CharField('Teléfono fijo', max_length=7, null=True, blank=True)
cellphone = models.CharField('Celular', max_length=10, null=True, blank=True)
email = models.EmailField('Correo', max_length=100, null=True, blank=True )
address = models.CharField('Dirección', max_length=70, null=True, blank=True)
gender = models.CharField('Genero',null=True, max_length=1, choices=GENDER_TYPE)
affiliate_type = models.CharField('Tipo de afiliado',null=True, max_length=12, choices=AFFILIATE_TYPE)```
#view
```class AccountList(APIView):
"""
List all accounts, or create a new account....
"""
def get(self, request, format=None):
account = Account.objects.all()
serializer = AccountSerializer(account, many=True)
filter_class = AccountFilter
filter_backends = [filters.SearchFilter]
return Response({'data':serializer.data},status=status.HTTP_200_OK)
def post(self, request, format=None):
serializer = AccountSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response({'Message':'Registro creado exitosamente'}, status=status.HTTP_201_CREATED)
return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)```
#filter
class AccountFilter(django_filters.rest_framework.FilterSet):
class Meta:
model = Account
fields = {
'document': ['exact'],
'document_type': ['exact']
}
ordering_fields = ('document')

You can use self.filter_queryset(queryset) to filter queryset using filter class.
class AccountList(APIView):
def get(self, request, format=None):
self.filter_class = AccountFilter
self.filter_backends = [filters.SearchFilter]
account_qs = Account.objects.all()
account = self.filter_queryset(account_qs)
serializer = AccountSerializer(account, many=True)
return Response({'data':serializer.data},status=status.HTTP_200_OK)
