# werkzeug.LocalProxy¶

class werkzeug.LocalProxy(local, name=None)[source]

Acts as a proxy for a werkzeug local. Forwards all operations to a proxied object. The only operations not supported for forwarding are right handed operands and any kind of assignment.

Example usage:

from werkzeug.local import Local
l = Local()

# these are proxies
request = l('request')
user = l('user')

from werkzeug.local import LocalStack
_response_local = LocalStack()

# this is a proxy
response = _response_local()


Whenever something is bound to l.user / l.request the proxy objects will forward all operations. If no object is bound a RuntimeError will be raised.

To create proxies to Local or LocalStack objects, call the object as shown above. If you want to have a proxy to an object looked up by a function, you can (as of Werkzeug 0.6.1) pass a function to the LocalProxy constructor:

session = LocalProxy(lambda: get_current_request().session)


Changed in version 0.6.1: The class can be instanciated with a callable as well now.
