Hey Everybody,
I''m new to RoR and I''m awfully confused on how to retrieve
data from
sessions. I do know session variables are stored in a hash.
Anyway, I have two models - Note and User
In User, I have a method called login that populates session[:user] --
I also got fedup, and tried storing just the id of the user in
session[:user_id]...
In Note, I want to retreive the ID of the user who is logged in.
Forgive me if what I''m doing is stupid, but I always get the error:
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.[]
Here''s my code in note.rb
class Note < ActiveRecord::Base
def self.my_notes
temp_email = @session[:user_email]
temp = User.get_id(temp_email)
Note.find_by_sql ["SELECT * FROM notes WHERE user_owner = ?", temp]
end
end
Please help me ;)

You can''t access the session from model classes. Session stuff belongs in the controller Fred -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Try changing @session[:user_email] to session[:user_email] in both the assignment and access statements. hth, Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
