Rails - session information being cleared?
- by Jty.tan
Hi!
I'm having a weird issue that I can't track down...
For context, I have resources of Users, Registries, and Giftlines. Each User has many Registries. Each Registry has many Giftlines. It's a belongs to association for them in a reverse manner.
What is basically happening, is that when I am creating a giftline, the giftline itself is created properly, and linked to its associated Registry properly, but then in the process of being redirected back to the Registry show page, the session[:user_id] variable is cleared and I'm logged out.
As far as I can tell, where it goes wrong is here in the registries_controller:
def show
@registry = Registry.find(params[:id])
@user = User.find(@registry.user_id)
if (params[:user_id] && (@user.login != params[:user_id]) )
flash[:notice] = "User #{params[:user_id]} does not have such a registry."
redirect_to user_registries_path(session[:user_id])
end
end
Now, to be clear, I can do a show of the registry normally, and nothing weird happens. It's only when I've added a giftline does the session[:user_id] variable get cleared.
I used the debugger and this is what seems to be happening.
(rdb:19) list
[20, 29] in /Users/kriston/Dropbox/ruby_apps/bee_registered/app/controllers/registries_controller.rb
20 render :action => 'new'
21 end
22 end
23
24 def show
=> 25 @registry = Registry.find(params[:id])
26 @user = User.find(@registry.user_id)
27 if (params[:user_id] && (@user.login != params[:user_id]) )
28 flash[:notice] = "User #{params[:user_id]} does not have such a registry."
29 redirect_to user_registries_path(session[:user_id])
(rdb:19) session[:user_id]
"tester"
(rdb:19)
So from there we can see that the code has gotten back to the show command after the item had been added, and that the session[:user_id] variable is still set.
(rdb:19) list
[22, 31] in /Users/kriston/Dropbox/ruby_apps/bee_registered/app/controllers/registries_controller.rb
22 end
23
24 def show
25 @registry = Registry.find(params[:id])
26 @user = User.find(@registry.user_id)
=> 27 if (params[:user_id] && (@user.login != params[:user_id]) )
28 flash[:notice] = "User #{params[:user_id]} does not have such a registry."
29 redirect_to user_registries_path(session[:user_id])
30 end
31 end
(rdb:19) session[:user_id]
"tester"
(rdb:19)
Stepping on, we get to this point.
And the session[:user_id] is still set.
At this point, the URL is of the format localhost:3000/registries/:id, so params[:user_id] fails, and the if condition doesn't occur. (Unless I am completely wrong .<)
So then the next bit occurs, which is
(rdb:19) list
[1327, 1336] in /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb
1327 end
1328
1329 def perform_action
1330 if action_methods.include?(action_name)
1331 send(action_name)
=> 1332 default_render unless performed?
1333 elsif respond_to? :method_missing
1334 method_missing action_name
1335 default_render unless performed?
1336 else
(rdb:19) session[:user_id]
"tester"
And then when I hit next...
(rdb:19) next
2: session[:user_id] =
/Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/filters.rb:618
return index if nesting != 0 || aborted
(rdb:19) list
[613, 622] in /Library/Ruby/Gems/1.8/gems/actionpack-2.3.5/lib/action_controller/filters.rb
613 private
614 def call_filters(chain, index, nesting)
615 index = run_before_filters(chain, index, nesting)
616 aborted = @before_filter_chain_aborted
617 perform_action_without_filters unless performed? || aborted
=> 618 return index if nesting != 0 || aborted
619 run_after_filters(chain, index)
620 end
621
622 def run_before_filters(chain, index, nesting)
(rdb:19) session
{:user_id=>nil, :session_id=>"49992cdf2ddc708b441807f998af7ddc", :return_to=>"/registries", "flash"=>{}, :_csrf_token=>"xMDI0oDaOgbzhQhDG7EqOlGlxwIhHlB6c71fWgOIKcs="}
The session[:user_id] is cleared, and when the page renders, I'm logged out. .<
Sooo.... Any idea why this is occurring?
It just occurred to me that I'm not sure if I'm meant to be pasting large chunks of debug output in here... Somebody point out to me if I'm not meant to be doing this. .
And yes, this only occurs when I have added a giftitem, and it is sending me back to the registry page. When I'm viewing it, the same code occurs, but the session[:user_id] variable isn't cleared.
It's driving me mildly insane.
Thanks!
