error when using active_record_store which doesn't happen using cookie_store ...

when I start my app with cookie_store, no error…

but when I change for active_record_store ( because of cookies overflow…) then I get an error :

TypeError in WelcomeController#home

can't convert Symbol into String

using a debugger in the WelcomeController#home

class WelcomeController < ApplicationController

respond_to :html

before_filter :store_location

before_filter :authenticate_user!, :only => :page3

def home



the issue seems to be originated after the rendering... ( which is the same when I use the cookie_store)

Processing by WelcomeController#home as HTML

Parameters: {"locale"=>:en}

Rendered welcome/home.en.html.haml within layouts/application (6.3ms)

Rendered layouts/users/_language.html.haml (15.9ms)

Rendered layouts/users/_navbar.html.haml (1173.4ms)

Rendered layouts/users/_footer.html.haml (3.4ms)

Completed 200 OK in 112208ms (Views: 2885.3ms | ActiveRecord: 0.0ms)

what could be wrong .. any clue ?

not solved but seems to be an issue related to

active_record_store “domain: :all” TypeError
