Attached is a patch that enables client-side full-page redirects from Ajax
requests. It alters the redirect() function in http.py as well as adding an
event handler in web2py.js. With it, in a function called via Ajax, you can
do:
def my_ajax_function():
if some_condition:
redirect(URL('default', 'other_function', extension=False), type=
'client')
return dict()
In that case, redirect does not raise an HTTP(303). Instead, it raises an
HTTP(200) and sets a special "web2py-redirect-location" response header
with the redirect URL. On the client side, a jQuery.ajaxSuccess event
handler checks for that header on every successful Ajax request, and if the
header is there, it sets window.location to that URL, which loads the full
page in the browser window. Note, if redirecting from a function called
with the .load extension, you probably want to set extension=False when
constructing the redirect URL so the .load extension is not propagated to
the redirect.
Eventually, we might consider adding a type='internal' option to the
redirect() function, which could generate a new internal request to the
redirect URL rather than sending a 303 to the server (this would have
nothing to do with Ajax -- just a way of speeding up regular server-side
redirects when you don't need the browser to receive a new URL with the
redirect).
