由于设计，来自模板的新 rails 应用程序失败
New rails app from template fails because of devise
我创建了一个 rails 应用程序模板 (https://github.com/alec-c4/kickstart) 并且我使用设计 gem 作为身份验证解决方案。一切正常，但有时新的应用程序生成器崩溃

我已经通过在 user.rb 文件中添加
行解决了这个问题
extend Devise::Models
但它看起来是一种解决方法，而不是永久解决方案。知道如何解决吗？
认为您可能需要 运行 生成器，以便它可以创建设计初始化文件。 /config/initializers/devise.rb
rails generate devise:install
如果上述崩溃，您可能需要注释掉 User.rb 中的 devise :database_authenti... 行并再次 运行 生成器
我正在通过 phone 查看您的代码，所以请原谅任何错误 :)

我已经通过在 user.rb 文件中添加
行解决了这个问题extend Devise::Models
但它看起来是一种解决方法，而不是永久解决方案。知道如何解决吗？
认为您可能需要 运行 生成器，以便它可以创建设计初始化文件。 /config/initializers/devise.rb
rails generate devise:install
