I will have standard class-based views for CRUD operations that inherit from various generic views like ListView, DetailView and so on.
I will be setting all of their
context_object_name
attribute to the same value.

I was wondering if there is a way to do it more pythonic, to not repeat the operations many times in the code, but to be able to change that variable in one place if necessary?

ps. what comes to my mind is of course further inheritance, but maybe there is some more django-like way?

Middleware can do the trick

class SetContextObjectNameMiddleware:

 def process_template_response(self, request, response):
 if 'object' in response.context_data:
 response.context_data['foo'] = response.context_data['object']
 return response

Then add the middleware to your settings.py

It's not really setting the view's context_object_name but it achieves the same outcome.

You can also use a mixin, instead of a middleware app:

class CommonContextMixin(object):
 def get_context_data(self, *args, **kwargs):
 context = super(CommonContextMixin, self).get_context_data(*args, **kwargs)
 context['foo'] = 'bar'

 return context

Then use that mixin in your views:

class MyView(TemplateView, CommonContextMixin):
 """ This view now has the foo variable as part of its context. """
