使用 Rails 5 API 进行设计的 alias_method_chain 修复？

Question

Devise 一直给我这个消息DEPRECATION WARNING: alias_method_chain is deprecated. Please, use Module#prepend instead. From module, you can access the original method using super. (called from <class:RouteSet> at /.../.rvm/gems/ruby-2.2.3/gems/devise-3.3.0/lib/devise/rails/routes.rb:27) 这就是 Devise 的 routes.rb 的样子

module ActionDispatch::Routing
  class RouteSet #:nodoc:
    # Ensure Devise modules are included only after loading routes, because we
    # need devise_for mappings already declared to create filters and helpers.
    def finalize_with_devise!
      result = finalize_without_devise!

      @devise_finalized ||= begin
        if Devise.router_name.nil? && defined?(@devise_finalized) && self != Rails.application.try(:routes)
          warn "[DEVISE] We have detected that you are using devise_for inside engine routes. " \
            "In this case, you probably want to set Devise.router_name = MOUNT_POINT, where "   \
            "MOUNT_POINT is a symbol representing where this engine will be mounted at. For "   \
            "now Devise will default the mount point to :main_app. You can explicitly set it"   \
            " to :main_app as well in case you want to keep the current behavior."
        end

        Devise.configure_warden!
        Devise.regenerate_helpers!
        true
      end

      result
    end
    alias_method_chain :finalize!, :devise
  end

这里可以快速修复吗？

Answer 1

候选设计版本支持 Rails 5，将其放入 ol' Gemfile

gem "devise", '~> 4.0.0.rc1'

Answer 2

请检查以下内容：

1) Rails 5 的 routes.rb 文件的更新代码中有这个要点

https://raw.githubusercontent.com/chbonser/devise/f05dd9dddb33cbc1739266637eafa2299661f517/lib/devise/rails/routes.rb

或

2) 使用终端获取 gem 文件夹路径：

gem environment

你应该得到路径，这将帮助你找到设计 gem 文件夹。

浏览以设计 gem（类似这样的东西）：

cd /usr/local/rvm/gems/ruby-2.2.2/gems/devise-3.5.2/lib/devise

并编辑/更新文件，如 failure_app.rb：

nano failure_app.rb
