title: How to delete Devise table to run 'rake db:migrate'?
body: <p>I am adding devise to my web application in Rails 3.2.12. I ran a successful <code>$ rails generate devise:install</code> and <code>$ rails generate devise User</code>. </p>
  
  <p>This is what I get when I run <code>$ rake routes</code>:</p>
  
  <pre><code>         new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
               user_session POST   /users/sign_in(.:format)       devise/sessions#create
       destroy_user_session DELETE /users/sign_out(.:format)      devise/sessions#destroy
              user_password POST   /users/password(.:format)      devise/passwords#create
          new_user_password GET    /users/password/new(.:format)  devise/passwords#new
         edit_user_password GET    /users/password/edit(.:format) devise/passwords#edit
                            PUT    /users/password(.:format)      devise/passwords#update
   cancel_user_registration GET    /users/cancel(.:format)        devise/registrations#cancel
          user_registration POST   /users(.:format)               devise/registrations#create
      new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
     edit_user_registration GET    /users/edit(.:format)          devise/registrations#edit
                            PUT    /users(.:format)               devise/registrations#update
                            DELETE /users(.:format)               devise/registrations#destroy
                       root        /                              pages#home
                      about GET    /about(.:format)               pages#about
  </code></pre>
  
  <p>When I attempt to run <code>rake db:migrate</code>, I get the following <strong>error</strong>:</p>
  
  <pre><code> ==  DeviseCreateUsers: migrating ==============================================
   -- create_table(:users)
   rake aborted!
   An error has occurred, this and all later migrations canceled:
  
   SQLite3::SQLException: table "users" already exists: CREATE TABLE "users" ("id" INTEGER PRIMARY     KEY AUTOINCREMENT NOT NULL, "email" varchar(255) DEFAULT '' NOT NULL, "encrypted_password"    varchar(255) DEFAULT '' NOT NULL, "reset_password_token" varchar(255), "reset_password_sent_at"    datetime, "remember_created_at" datetime, "sign_in_count" integer DEFAULT 0, "current_sign_in_at"    datetime, "last_sign_in_at" datetime, "current_sign_in_ip" varchar(255), "last_sign_in_ip"    varchar(255), "created_at" datetime NOT NULL, "updated_at" datetime NOT NULL)   /Users/andyHuynh/.rvm/gems/ruby-1.9.3-p327/gems/sqlite3-1.3.7/lib/sqlite3/database.rb:91:in    `initialize' 
  </code></pre>
  
  <p>It's telling me I have a 'users' table already. If this is the case, where is this sql table? Thanks in advance for any help! </p>
