Switching to ActiveRecord Session Store


#1

I’m having a problem switching from cookie sessions (the default) to
active record sessions.

I’ve created the sessions table via the rake task, uncommented the
line

config.action_controller.session_store = :active_record_store

in my environment.rb file, cleared out my browsers cookies, restarted
the server (natch), but still the it’s using cookie_store instead of
active_record store. Just to be sure, I added puts statements in the
initializer block of each separate store’s ruby classes in vendor
rails, and only “cookie_store initialized” come out.

What am I missing here? I’ve tried commenting out the secret key
lines:

#config.action_controller.session = {

:session_key => ‘_sm_session’,

:secret => ‘thisisJohnsSecretCodeItNeedsLotsofCharacters’

#}

but I immediately get server failures because the cookie store needs
them and is still active. I also tried replacing the
config.action_controller.session_store = :active_record_store line
with :

ActionController::Base.session_store = :active_record_store
ActionController::Base.session_options[:expire_after]=2.years

after the initializer block in environment.rb, but it apparently had
no effect, still the cookie_store turns on.

So, any suggestions or guidance appreciated.

ps. The reason I’m trying to switch is that I’m trying to get Facebook
Connect to work via Facebooker, and apparently it requires the
activerecord session store to be used.

Thanks in advanced,

John

Hi John,

Hard to tell, but I’m wondering if you forgot to run rake:db:migrate
after running rake db:sessions:create? The latter creates the
migration file in db/migration/, and the former actually creates the
table in the db. Check your db to make sure the sessions table does
exist.

If you did and the tbl does exist, then it’s hard to tell what’s going
on with your setup. If you can’t find what the problem is, you could
try the following test to see if you can’t get db sessions working:

rails version?

$ rails --version
Rails 2.2.2

create a test proj:

$ rails testsess

$ cd testsess/

$ cat config/database.yml
development:
adapter: sqlite3
database: db/development.sqlite3
pool: 5
timeout: 5000

mod environment.rb to use db for sess data:

$ cat config/environment.rb

config.action_controller.session_store = :active_record_store

create sess and migrate:

$ rake db:sessions:create

$ rake db:migrate

$ sqlite3 db/development.sqlite3 ‘.tables’
schema_migrations sessions

$ sqlite3 db/development.sqlite3 ‘.schema sessions’
CREATE TABLE “sessions” (“id” INTEGER PRIMARY KEY AUTOINCREMENT NOT
NULL, “session_id” varchar(255) NOT NULL, “data” text, “created_at”
datetime, “updated_at” datetime);
CREATE INDEX “index_sessions_on_session_id” ON
“sessions” (“session_id”);
CREATE INDEX “index_sessions_on_updated_at” ON
“sessions” (“updated_at”);

$ sqlite3 db/development.sqlite3 ‘select count(id) from sessions’
0

create test controller and index:

$ ./script/generate controller testsess

$ cat app/controllers/testsess_controller.rb
class TestsessController < ApplicationController
def index
# test storing something in session …
session[:ip] = request.remote_addr if not session[:ip]
@ip = session[:ip]
end
end

$ cat app/views/testsess/index.html.erb
Hi <%= @ip %>.

start dev env and hit it with browser (or wget or …):

$ ./script/server -p 3044 -d

$ wget -o /dev/null -O - http://localhost:3044/testsess/
Hi 127.0.0.1.

was sess data stored in db?

$ sqlite3 db/development.sqlite3 ‘select count(id) from sessions’
1

yes:

$ sqlite3 db/development.sqlite3 ‘select id, updated_at from sessions’
1|2009-02-19 04:23:06

done.

$ kill cat tmp/pids/mongrel.pid
