I am using TG 2.0.4. Till now I used to save the user_id in the __before__
method of a controller and use it later in an exposed method of the same
controller. During testing, I came across a scenario (race condition)
where the self.user_id is not what I expected inside foo(). It seems that
self.user_id is overwritten by request2 when I am processing request1 in
parallel. All along I thought that the values stored in the controller
self variable are request specific. I figure my understanding is wrong.
Can someone confirm!
If I want to store request specific information to be used later in the
processing, should I store it in the *request *object itself? Or maybe
create a req_context object and store all the needed information, and add
the req_context object to the request.
Any other suggestions welcome.
Thanks
def __before__(self, *args, **kw):
tmpl_context.menu_items = self.menu_items
tmpl_context.title = title
identity = request.environ.get('repoze.who.identity')
self.user_id = identity['user'].user_id
self.user_name = identity['user'].user_name
@expose()
def foo(self):
# use self.user_id for some operation

__before__(**args*, ***kw*)Override this method to define any action you
would like taken before the controller code is executed. This is
particularly useful for defining a Controller-wide specification (all
methods) for things like: setting up variables/objects in the template
context, restricting access, or other tasks which should be executed before
the controller method is called.
