ruby - 如何正确使用 mongoid-rspec gem？

Question

已关注 instructions我已经安装了mongoid-rspec并在spec_helper.rb中配置了它

RSpec.configure do |config|
  config.include Mongoid::Matchers, type: :model
end

但是用最简单的测试遇到了问题

describe City do
  it { should have_many(:locations) }
end

City should have many :locations
     Failure/Error: it { should have_many(:locations) }
     NoMethodError:
       undefined method `has_many?' for 

似乎我做错了，但无法弄清楚到底哪里错了。

模型非常简单

class City
  include Mongoid::Document
  include Mongoid::Timestamps
  include Mongoid::Paranoia
  include Mongoid::Versioning
  max_versions 10

  has_many :locations
end

class Location
  include Mongoid::Document
  belongs_to :city
  field :name, type: String
end

最后一件事，我不使用 Rails。

Answer 1

我遇到了类似的问题，但在处理 Rails 时，我认为 Rails 和 None Rails 的解决方案非常相似:

gem 'mongoid-rspec', '~> 2.2.0'

无导轨

添加到您的spec_helper.rb 文件:

require 'mongoid-rspec'

RSpec.configure do |config|
  config.include Mongoid::Matchers
end

带导轨

添加到您的rails_helper.rb

require 'mongoid-rspec'

RSpec.configure do |config|
  config.include Mongoid::Matchers, type: :model
end
