Can a decorator of an instance method access the class?

Question

I have something roughly like the following. Basically I need to access the class of an instance method from a decorator used upon the instance method in its definition.

Answer 1

You will have access to the class of the object on which the method is being called in the decorated method that your decorator should return. Like so:

def decorator(method):
    # do something that requires view's class
    def decorated(self, *args, **kwargs):
        print 'My class is %s' % self.__class__
        method(self, *args, **kwargs)
    return decorated

Using your ModelA class, here is what this does:

>>> obj = ModelA()
>>> obj.a_method()
My class is <class '__main__.ModelA'>
