Sorry, my fault.
I forgot that Pylons based versions of TG reallocate the controller on
each request, as you are hooking the before_validate inside the
__init__ this has the side effect of registering the validate hook
each time you get a request.
Change it to something like:
class MyGroupRestController(EasyCrudRestController):
model = model.Group
def before_put(self, *args, **kw):
print args, kw
before_validate(MyGroupRestController.before_put)(MyGroupRestController.put)
This is one of the things that are going to change on in 2.3+ which
allocates the controllers only on application startup, in the mean
time you must avoid doing anything that changes the controller class
inside the init itself.
