You are declaring a get_context_data
inside the get_context_data
method. It should be:
def get_context_data(self, **kwargs):
# Only one declaration, otherwise None will be returned by the function
context = super(Developer_detail, self).get_context_data(**kwargs)
tasks_dev = Task.oblects.filter(developer=self.object)
context['tasks_dev'] = tasks_dev
return context
