✅

You can override DetailView’s get_context_data to add RoletoFunction model’s data to context. For example:

class FunctionDetail(DetailView):
     ...
     def get_context_data(self, **kwargs):
        context = super(FunctionDetail, self).get_context_data(**kwargs)

        if 'function_id' in kwargs:  #this is how you can get function_id's data from url
            _id = int(kwargs['function_id'] or '0')
        else:
            _id = 0
        function =  Function.objects.get(id=_id)
        context['role_function'] = RoletoFunction.objects.filter(function=function)
        return context
