轨道上的红宝石 - 未使用 MongoMapper 范围抛出错误列出数据 <Plucky：：查询状态："Active" >

Question

实际上，我通过使用mongomapper概念创建了两个模型，我提到了获取活跃作者的范围，但它的抛出错误像

模型1:

class Author
  include MongoMapper::Document         
  key :name, String
  key :status, String
  validates_presence_of :name
  many :books
  scope :active, where(:status => 'Active')
end

模型2:

class Book
  include MongoMapper::Document         
  key :title
  key :author_id, ObjectId
  key :status, :default => 'Active'
  validates_presence_of :title
  belongs_to :author
  scope :active, where(:status => 'Active')
end

视图:

Author.active.collect{|a| [a.name,a.id]}

Answer 1

使用提供的模型，视图查询为我提供了一个简单的示例。

测试/单位/author_test.rb

require 'test_helper'
class AuthorTest < ActiveSupport::TestCase
  def setup
    Author.delete_all
    Book.delete_all
  end
  test "scope active" do
    puts "nMongoMapper::Version:#{MongoMapper::Version}"
    Author.create(name: 'J. K. Rowling', status: 'Active')
    a = Author.active.collect{|a| [a.name,a.id]}
    assert_equal("J. K. Rowling", a.first.first)
    p a
  end
end

运行选项:

# Running tests:
[1/1] AuthorTest#test_scope_active
MongoMapper::Version:0.12.0
