The request object is automatically set on openerp.http.request at the start of the request
Controllers need to provide extensibility, much like Model, but can’t use the same mechanism as the pre-requisites (a database with loaded modules) may not be available yet (e.g. no database created, or no database selected).
Controllers thus provide their own extension mechanism, separate from that of models:
Controllers are created by inheriting from
and defining methods decorated with route():
class MyController(openerp.http.Controller):
@route('/some_url', auth='public')
def handler(self):
return stuff()
To override a controller, inherit from its class and override relevant methods, re-exposing them if necessary:
class Extension(MyController):
@route()
def handler(self):
do_before()
return super(Extension, self).handler()
decorating with route() is necessary to keep the method (and route) visible: if the method is redefined without decorating, it will be “unpublished”
the decorators of all methods are combined, if the overriding method’s decorator has no argument all previous ones will be kept, any provided argument will override previously defined ones e.g.:
class Restrict(MyController):
@route(auth='user')
def handler(self):
return super(Restrict, self).handler()
will change /some_url from public authentication to user (requiring a log-in)
