ActiveResource帖子引发错误，而在我的浏览器中发布帖子成功

标签： ruby-on-rails mongodb activeresource

我有一个非常奇怪的问题，我无法解决。两个Rails应用程序，一个是具有实体Mongo :: Enrollment的API，另一个是具有通过ActiveResource连接到API的实体Enrollment的客户端。

我使用ActiveResource在客户端上定义了我的/app/models/enrollment.rb，在控制器中我正在进行这样的调用：

enrollment = Enrollment.post(:create, enrollment: {
        :enrollment_type => :test,
        :enrollment_information => {test: 'test information'}
})

我知道我可以在这里使用.new和.save，因为它是ActiveResource，但它给了我相同的结果。

当我实际发布此消息时，我的日志中出现以下错误：

RuntimeError (Circular dependency detected while autoloading constant Enrollment)

但是如果我从我的日志中复制URL，使用相同的Basic身份验证，接受标头和POST方法将其粘贴到Postman中，我根本没有错误，它会将注册保存到mongodb。

我真的希望有人可以帮助我。我认为看起来完全相同的HTTP请求非常奇怪，取得了不同的结果。我尝试重新启动这两个应用程序，并以不同的方式从客户端执行请求，但每次我从客户端发出请求时，它都会给我上述错误。 API端的控制器和模型看起来很好，我在API应用程序上也有一个HTML界面，并且工作正常。

这就是我的API应用程序中的内容：

它在路由中定义为：

resources :enrollments

在EnrollmentsController中我有

# /app/controllers/enrollments_controller.rb
class EnrollmentsController < ApplicationController
  ...
  def create

    @enrollment = Mongo::Enrollment.new(enrollment_parameters)

    respond_to do |format|
      if @enrollment.save
        format.html { redirect_to @enrollment, notice: 'Note was successfully created.' }
        format.json { render json: @enrollment }
      else
        format.html { render action: 'new' }
        format.json { render json: @enrollment.errors, status: :unprocessable_entity }
      end
    end

  end
  ...
end

这是我的模特：

# /app/models/mongo/enrollment.rb
module Mongo
  class Enrollment
    include Mongoid::Document
    include Mongoid::Timestamps
    include Mongoid::Paranoia

    default_scope ->{ where(processed: false)}

    field :processed, :type => Boolean, :default => false
    field :accepted, :type => Boolean, :default => false

    field :enrollment_type

    field :enrollment_information, :type => Hash, :default => {}
  end
end

完整堆栈跟踪：

听起来wrap_parameters代码被您的模型在Mongo模块中命名空间这一事实所困惑。

听起来你实际上并不需要参数包装，所以最简单的方法就是禁用它 - 应该有一个wrap_parameters初始化器。如果需要，您可以在控制器的基础上在控制器上重新启用它。
