generate model error

I'm new on rails, and I encountered a problem when I am doing a tutorial: that's a simple application without a database.

First "rails simple_app" And modify "enviroment.rb"

  # Skip frameworks you're not going to use. To use Rails without a database,   # you must remove the Active Record framework.   config.frameworks -= [ :active_record, :active_resource, :action_mailer ]

However, after that when I execute the command "ruby script/generate model Item" there will be an error raised: uninitialized constant ModelGenerator::ActiveRecord

Anyone knows the origin of the problem, and how to solve it

BTW: I am using rails 2.3.4 and ruby 1.8.7

I may be wrong ( I often am ) but I would guess that the Model generator assumes that you are using ActiveRecord. It does generate migrations after all.

Unless you really want to use Rails without a db then I would give it one. You do not have to do anything with it in your first forays, just make it available to keep Rails happy.
