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
