Question

这是我尝试创建新模型时日志中的错误：

它来自 has_many_polymorphs 插件...

这里是 config/environment.rb：

# Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
Dreamstill::Application.initialize!

这是 /rubyprograms/dreamstill/vendor/plugins/has_many_polymorphs/lib/ has_many_polymorphs/configuration.rb：

module Rails #:nodoc:
  class Configuration

    def has_many_polymorphs_options
      ::HasManyPolymorphs.options
    end

    def has_many_polymorphs_options=(hash)
      ::HasManyPolymorphs.options = HashWithIndifferentAccess.new(hash)
    end

  end  
end

快速回答：

您的has_many_polymorphs插件已损坏。 上的 environment.rb 文件中，

我认为您已将其包含在第 5 行UPD

如您所见 /rubyprograms/dreamstill/vendor/plugins/has_many_polymorphs/ lib/has_many_polymorphs.rb:23 has_many_polymorphs.rb 文件 n 行有错误23.修复它：D。或者不要使用损坏的插件。

rails plugin remove has_many_polymorphs
