Reading n writing object attributes
Hi. In this simple example I have a User class with the class method:
def self.find_user(name)
user = self.find(:first, :conditions => ["username = ?", name])
# user.salt
end
In the rails console I do the following:
>> u = User.find_user(''kena'')
=> #<User id: 5, username: "test", hashed_password:
"c1a18d933c06f5a3ebd8d1d155d294f39447fbf2", salt:
"177647700.129851651671097", email: "", created_at:
"2008-10-28
00:54:42", updated_at: "2008-10-28
00:54:42">>> u.salt
=> nil>> u.username
=> nil
What I don''t understand is why I can''t access its attributes?

Soh,
Not sure why you are not able to access the attributes in the use case
but can I ask why you are not using the dynamic find_by methods ie
User.find_by_username(''kena'') ?

I didn''t have any private nor protected methods and I was reloading my console with: reload! ... I then decided to re-start my machine and now it works fine. Unfortunately I cannot reproduce that problem now ... let''s consider that a good thing ... thanks anyway :-) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
