Hi guys,
Following is a simple before filter under rails 2.02
users_controller.rb
class UsersController < ApplicationController
skip_before_filter :authorize, :only => [:login]
## CRUD actions #####
def login
if request.post?
session[:user] = nil
u = User.find_by_email params[:user][:email]
unless u && u.password_equal?(params[:user][:password])
session[:user] = u
uri = session[:original_uri]
session[:original_uri] = nil
redirect_to(uri || {:action => :index})
else
flash[:notice] = "the user name and email doesn''t
match!"
end
end
end
end
application_controller.rb
class ApplicationController < ActionController::Base
helper :all # include all helpers, all the time
# See ActionController::RequestForgeryProtection for details
# Uncomment the :secret if you''re not using the cookie session store
protect_from_forgery # :secret =>
''4477fc7de98463482e367d7b0d4279eb''
before_filter :authorize
protected
def authorize
p "step to authorize"
unless session[:user]
flash[:notice] = "please login first..."
session[:original_uri] = request.request_uri
redirect_to(:controller => "users", :action =>
"login")
end
end
end
when I get the url http://localhost:3000/users, it always do loop in
"authorize"
action and "step to authorize" appears several times and I got the
error
"Redirect Loop
Firefox has detected that the server is redirecting the request for
this address in a way that will never complete.
The browser has stopped trying to retrieve the requested item. The site
is redirecting the request in a way that will never complete.
* Have you disabled or blocked cookies required by this site?
* NOTE: If accepting the site''s cookies does not resolve the
problem, it is likely a server configuration issue and not your
computer."
what''s up? It seems it should work well, can anybody point this
problem?
I am under ubuntu 8.04 LTS, thanks.
