Class decorator

API

class rules_light.class_decorator.class_decorator

Can be used to secure class based views.

If the view has model=YourModel, it will support:

• CreateView, it will decorate get_form(), to run rules_light.require('yourapp.yourmodel.create'),
• UpdateView, it will decorate get_object(), to run rules_light.require('yourapp.yourmodel.update', obj),
• DeleteView, it will decorate get_object(), to run rules_light.require('yourapp.yourmodel.delete', obj),
• DetailView, it will decorate get_object(), to run rules_light.require('yourapp.yourmodel.read', obj),
• others views, if the rule name is specified in the decorator for example @class_decorator('some_rule'), then it will decorate dispatch(),
• Else it raises an exception.
