强制更改database.yml参数

Question

如何更改设置到database.yml中的参数？例如：将param编码到datavase.yml是utf8，但我需要将其设置为等于utfmb4，但我无法更改database.yml文件。我该怎么做？可能与config.active_record一起进入config/application.rb文件。？

Answer 1

我们可以将database.yml更改为其他文件名。将其粘贴到第11行的config/application.rb中（在定义bundler之后）

module Rails
  class Application
    class Configuration < ::Rails::Engine::Configuration
      def paths
        @paths ||= begin
          paths = super
          paths.add "config/database",    with: "config/database_actual.yml"
          paths.add "config/environment", with: "config/environment.rb"
          paths.add "lib/templates"
          paths.add "log",                with: "log/#{Rails.env}.log"
          paths.add "public"
          paths.add "public/javascripts"
          paths.add "public/stylesheets"
          paths.add "tmp"
          paths
        end
      end
    end
  end
end

并将database.yml移动到config/database_actual.yml
