Question

I try to call a function which checks a rule and if the rule is not fulfilled I’d like to skip the rest of the view code and just return a HttpResponse Error.

I’d like to put all the escaping logic in a function because I need it at several points all over my project.

I tried to do something like this:

def myView(request):

    checkFunction()

And:

def checkFunction():
    #do stuff
    return HttpResponse(status=403)

But it just don’t work (no wonder)…

Any ideas how to do this right?

Thanks

Ron

You can use a decorator for applying a logic to a view with possible redirect(if you can really put your logic outside the view).

def check_my_logic(view):
    def wrap(request, *args, **kwargs):
        # do some logic here
        if all_ok:
             return view(request, *args, **kwargs)
        else:
            return HttpResponse(status=403)
  return wrap

and then in views.py:

 from mydecorators import check_my_logic

 @check_my_logic
 def some_view(request):
     ....
