The request object is automatically set on :data:`odoo.http.request` at

the start of the request
|

|
|
|

|
|
.. autoclass:: odoo.http.WebRequest

Controllers
|
||
|
|
===========
|
||
|
|
|
||
|
|
Controllers need to provide extensibility, much like
|
||
|
|
:class:`~odoo.models.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 :ref:`inheriting <python:tut-inheritance>` from
|
||
|
|
|
||
|
|
.. autoclass:: odoo.http.Controller
|
||
|
|
|
||
|
|
and defining methods decorated with :func:`~odoo.http.route`::
|
||
|
|
|
||
|
|
class MyController(odoo.http.Controller):
|
||
|
|
@route('/some_url', auth='public')
|
||
|
|
def handler(self):
|
||
|
|
return stuff()
|
||
|
|
|
||
|
|
To *override* a controller, :ref:`inherit <python:tut-inheritance>` 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 :func:`~odoo.http.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will be "unpublished"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)
