hi all,
i am new in ruby on rails,i have one issue regarding the session in ruby
on rails.I am using session , i have following condition in my rhtml
<%if @session[''user''].first_name ==
"admin"%>
<table width="290" border="0"
height="20" align="right"
cellspacing="0" cellpadding="0">
but this ''session'' is coming nil.i tried by setting
config.action_controller.session = { :key =>
"_suggestica_admin_session",
:secret =>
"80a6825007749a785439ca8d3ff54ac37a16acefea4788fa8c9ac8e69aef11eb7f3b06ab6e8d4a0e5023fb8e8a22ea197ee74828e16d8ab7e3e130fd0da7bea5"
}
this in environment.rb also tried setting value in session_store.rb
ActionController::Base.session = {
:key => ''_suggestica_admin_session'',
:secret =>
''35659c1f21207ecfeaf30aa32b72c717158eae4c41e665b7a31b26fc021890be31c8ed961cf695384030d34e3f3d0c8788d4733aac393e4003e077317c930b57''
}
but this also didn''t work
can any one know how to set the session for Rails 2.3.11 and gem
version:1.6.2 and Ruby 1.8.7 on Windows as O.S

Thanks and Regards

In rails session data is accessible only in controller. And thats how its meant to be according to MVC. If you really need it in view you need to set an instance variable in controller and use it in view. But thats very bad and not supposed to be done. If you are accessing session data in views, i think you need to rethink your design to be more inline with mvc pattern.

The session is perfectly accessible from the views (although you''re right - it *should* be avoided)> If you really need it in view you need to set an instance variable in > controller and use it in view.If you look again at the code in the OP, you''ll see it''s trying to be accessed as an instance variable - which almost certainly hasn''t been set. If the OP wants to just change : @session[''user''].first_name to session[''user''].first_name ...it may miraculously start working. Two things... a) Please don''t store whole objects in session. It''s really stinky. Store the id, and reload it with each request. b) Rather than the repetition of accessing session["user"] attributes everywhere. Set a helper method in the application controller which returns the current user (or use an authentication Gem that does it for you) Something like: def current_user @current_user ||= User.find(session[:user_id]) end Then set up methods in your user class to manage permissions (to make them easier to manage). # user.rb def has_admin_rights? first_name == "admin" end # view <%if current_user.has_admin_rights? %> <table width="290" border="0" height="20" align="right" cellspacing="0" cellpadding="0"> ...see how it makes the code in the view more "self documenting"... Also, look at abstracting things like roles (admin, user, guest, etc) and statuses (awaiting_validation, active, retired) to state machines rather than "magic-number" text comparisons on first-name fields :-/ HTH -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
