Generating User Authentication System - rake db:migrate does nothing.


I'm not sure where I went wrong! I added the new fields to the DeviseCreateUsers table, and then attempted to migrate. However, nothing happens... and when I type rake routes this is what I get:

miralinastewart:~/projects/treebook> rake routes statuses GET /statuses(.:format) statuses#index POST /statuses(.:format) statuses#create new_status GET /statuses/new(.:format) statuses#new edit_status GET /statuses/:id/edit(.:format) statuses#edit status GET /statuses/:id(.:format) statuses#show PUT /statuses/:id(.:format) statuses#update DELETE /statuses/:id(.:format) statuses#destroy root / statuses#index

As you can see, the devise table is completely missing. Any help greatly appreciated!

here is the ######_devise_create_users.rb ... is that the migration file?

  class DeviseCreateUsers < ActiveRecord::Migration
  def change
  create_table(:users) do |t|
  t.string :first_name
  t.string :last_name
  t.string :profile_name

  ## Database authenticatable
  t.string :email,              :null => false, :default => ""
  t.string :encrypted_password, :null => false, :default => ""

  ## Recoverable
  t.string   :reset_password_token
  t.datetime :reset_password_sent_at

  ## Rememberable
  t.datetime :remember_created_at

  ## Trackable
  t.integer  :sign_in_count, :default => 0
  t.datetime :current_sign_in_at
  t.datetime :last_sign_in_at
  t.string   :current_sign_in_ip
  t.string   :last_sign_in_ip

  ## Confirmable
  # t.string   :confirmation_token
  # t.datetime :confirmed_at
  # t.datetime :confirmation_sent_at
  # t.string   :unconfirmed_email # Only if using reconfirmable

  ## Lockable
  # t.integer  :failed_attempts, :default => 0 # Only if lock strategy is :failed_attempts
  # t.string   :unlock_token # Only if unlock strategy is :email or :both
  # t.datetime :locked_at

  ## Token authenticatable
  # t.string :authentication_token


add_index :users, :email,                :unique => true
add_index :users, :reset_password_token, :unique => true


I'm having the same problem...hmm. I put something up on Stackoverflow. When I find out anything, I'll let you know :)

Can you please post that migration file?

I think there is a little confusion here migrations and routes are two separate things.

Migrations change the structure of the database tables. In rails the model's attributes are the table columns - so migrations change the model's attributes. The easiest way to see the changes are in the rails console (at the command line type: rails console). And then doing a new object and seeing the attributes (type: User.new).

The routes, the URL's the application respond to, are changed by updating config/routes.rb and then restarting the rails server. If you now do: rake routes the changes should be seen.
