ruby-on-rails - 我在 rails generate devise :install 之前运行了 rails generate devise MODEL

Question

我在运行初始 Devise 生成器之前不小心添加了我的 Devise 模型。

我先运行的代码:

$ rails generate devise MODEL

初始设计生成器(我应该先运行的):

$ rails generate devise:install

我现在有一个名为 Model 的设计 Controller ，它不允许我运行“rake db:migrate”

错误:

rake aborted!
    User does not respond to 'devise' method. This usually means you haven't loaded your ORM file or  it's being loaded too late. To fix it, be sure to require 'devise/orm/YOUR_ORM' inside      'config/initializers/devise.rb' or before your application definition in 'config/application.rb'

有没有一种方法可以撤消此过程以先运行初始生成器？我正在使用 Rails 3.2.12。任何帮助表示赞赏。谢谢

您可以使用 rails destroy ... 撤消生成命令，因此在您的情况下它将是:

$ rails destroy devise MODEL

如果出于某种原因这不起作用，您可以删除模型和迁移 - 它们只是文件。
