Question

当我尝试创建新模型时，这是我的日志中的错误：

来自has_many_polymorphs插件...

这是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。我认为你已将它包含在LINE 5的environment.rb文件中

<强> UPD

正如您所见/rubyprograms/dreamstill/vendor/plugins/has_many_polymorphs/lib/has_many_polymorphs.rb:23 {23}中的has_many_polymorphs.rb文件中存在错误。修复它：D。或者不要使用破损的插件。

rails plugin remove has_many_polymorphs

has_many_polymorphs插件给了我这个错误
