Question

我在运行初始Devise生成器之前意外添加了我的Devise模型。

代码我先跑：

$ rails generate devise MODEL

初始设计生成器（我应该首先运行）：

$ rails generate devise:install

我现在有一个名为Model的设计控制器，它不会让我运行'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'

有没有办法可以撤消此过程以首先运行初始生成器？我正在使用Rails 3.2.12。任何帮助表示赞赏。感谢

Answer 1

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

如果由于某种原因无效，您可以删除模型和迁移 - 它们只是文件。

Answer 2

rails destroy model devise：user 要么 rails destroy scaffold devise：user

我在rails生成设计之前运行了rails generate devise MODEL：install
