Question

I am doing the following tutorial, to learn how to use dhtml in rails.

http://www.dhtmlx.com/blog/?p=426

I reach the point where I create the migration however when I do the rake db:migrate I recieve the following error:

An error has occurred, this and all later migrations canceled:

uninitialized constant CreateUsers::User

Don’t seem to understand how I can possibly be recieving this error especially by simply following a tutorial. “/

Answer 1

Make sure you generate the User model before running the migration. (ruby script/generate model user in the tutorial, but rails g model User for Rails 3)

EDIT: As Jeremy pointed out, generating the model will create a migration file for you. The tutorial shows things in a somewhat backwards order.
