Rails Server - Missing Method

When I try to start the rails server I get an error message saying I have a missing method or undefined method 'attr_accessible' for User.

The actual message looks like this (another persons' error message may look differently because they may have a different file setup or file names):

c:/Ruby193/lib/ruby/1.9.1/gems/activerecord-4.1.0/lib/active_record/dynamic_matchers.rb:26:in 'method_missing': undefined method 'attr_accessible' for User (call 'User.connection' to establish a connection):Class (NoMethodError)

I tried to enter User.connection into the prompt just to see if that would work but I get the error message: 'User.connection' is not recognized as an internal or external command, operable program or batch file.

Attr_accessible does not exist in Rails 4. The videos you are watching use rails 3.2, I suggest changing the version of rails in your gemfile and sticking to rails 3.2

OR

Skip the Treebook videos and first do the ODOT ruby on rails courses. They use rails 4 and will help you make more sense of what's going on in the Treebook videos.
