使用 Mongoid 和 rspec 测试named_scope

发布于 2024-12-13 04:45:39 字数 1624 浏览 1 评论 0原文

我是 RoR 的新手，我正在尝试为我的模型测试一个简单的named_scope。

但我不知道我的模型（我使用 mongoid）、代码测试（我使用 rspec）或我的工厂是否有问题。我收到这个错误

Mongoid::错误::无效集合：不允许访问移动集合，因为它是嵌入文档，请从根访问集合文档。

我的模型

class Movement
    include Mongoid::Document
    field :description, :type => String
    embedded_in :category

    named_scope :top, lambda { |number| { :limit => (number.size > 0 ? number : 10) } }    
end

class Category
  include Mongoid::Document
  field :name
  embeds_many :movement
end

我的工厂，confactory_girl

Factory.define :movement do |m|
  m.amount 24
  m.date "30/10/2011"
  m.description "Beer"
  m.association :category, :factory => :category
end

Factory.define :category do |c|
  c.name "Drink"
end

我的测试

describe "when i have a movement list" do
  it "recent method should return last 2 movements" do
    @movements = (1..3).collect { Factory(:movement) }
    recent_movements = Movement.top(2)
    recent_movements.should have(2).entries
  end
end

和错误：

Mongoid::错误::无效集合：不允许访问移动集合，因为它是嵌入的 > 文档，请从根文档访问集合。

我尝试在工厂里做一些改变。

   Factory.define :movement do |m|
      m.amount 24
      m.date "30/10/2011"
      m.description "Beer" 
      m.category { [ Factory.build(:category) ] }
    end

但后来我得到了其他不同的错误：

失败/错误：@movements = (1..3).collect { Factory(:movement) } 无方法错误： # 的未定义方法“reflect_on_association”

有人可以帮助我吗？

谢谢

原文

I'm newbie in RoR, and I am trying to test a simple named_scope for my Model.

But I don't know if I have a problem in my model (I'm using mongoid), in my code test (I'm using rspec) or in my factory. I got this error

Mongoid::Errors::InvalidCollection:
Access to the collection for Movement is not allowed since it is an embedded document, please access a collection from the root
document.

My models

class Movement
    include Mongoid::Document
    field :description, :type => String
    embedded_in :category

    named_scope :top, lambda { |number| { :limit => (number.size > 0 ? number : 10) } }    
end

class Category
  include Mongoid::Document
  field :name
  embeds_many :movement
end

My factory, con factory_girl

Factory.define :movement do |m|
  m.amount 24
  m.date "30/10/2011"
  m.description "Beer"
  m.association :category, :factory => :category
end

Factory.define :category do |c|
  c.name "Drink"
end

My test

describe "when i have a movement list" do
  it "recent method should return last 2 movements" do
    @movements = (1..3).collect { Factory(:movement) }
    recent_movements = Movement.top(2)
    recent_movements.should have(2).entries
  end
end

And the error:

Mongoid::Errors::InvalidCollection:
Access to the collection for Movement is not allowed since it is an embedded >document,
please access a collection from the root document.

I tried a little change in my factory.

   Factory.define :movement do |m|
      m.amount 24
      m.date "30/10/2011"
      m.description "Beer" 
      m.category { [ Factory.build(:category) ] }
    end

But then I got other different error:
