python - Standard way to pull a specific model from a common view in Django/DRF? -

i have 2 models same (inheriting base model), have problems referring them common view:

models:

class basemodel(models.model):     name = models.charfield(...)     owner = foreignkey(...)  class cat(basemodel):     ...  class dog(basemodel):     ... 

view:

class commonviewset(viewsets.modelviewset):     @link()     def set_owner(self, request, pk=none):          #how cat or dog models cleanly here?          #super fugly/unstable way         url_path = request.meta['path_info']         if 'cats' in url_path:             cat.objects.get(pk=pk).owner = ...         elif 'dogs' in url_path:             dog.objects.get(pk=pk).owner = ... 

i can put set_owner link in separate views, feels un-dry. in advance looking this!

you can pass model use in as_view method of class:

url(r'^cats/my-url/$', commonviewset.as_view(model=cat)), 

the modelviewset class inherits django's view class, set model attribute on instance of viewset. can use self.model right model current url.
