Greetings, I have a problem with attr_accessor and create seemingly being at odds with each other in my environment. Here is the setup: A simple class representing a US State (say, Maine for example): class State < ActiveRecord::Base attr_accessor(:name, :code) end In an IRB session, I type the following and receive the response included below: >>

I have more or less the same problem. I''m trying to build a system where users can enter their friends. But the solutions seems not to work for me.

Hi, I''ve got a model with the following attribute added: attr_accessor :level which does not exist in the database. After putting instances of this model in the cache (using Rails.cache.fetch(''foo'') { Category.all } ), when I retrieve it back from the cache, then trying to access .level gives: undefined method `level'' for #<Category:0x34d50a0>

After that when I try to run the app the app always says my other fields are blank, but they''re all filled up. What''s wrong with it?

I''m having trouble understanding Ruby''s concept of scope. Could someone explain the difference between the following 2 programs. They both return the same output "aaaaaaaa", but I''m just not sure about self in #1. Is self.day and self.title referring to and setting class variables or are they instance variables?

Great plugin, but my implementation is lame. I need enlightenment. I have users who log in. For several views I want to let them add comments.

Hi list, first evening of playing with rails, so please forgive me if I ask something stupid. ;-) I created a User model and tried to use ActiveRecord callbacks to convert the password to sha1 just before saving it. For some reason postgresql gives me a error because the given password is null. To test even further I tried to change :login too, same error happens, :login is empty too. I am sure
