我用Rails3.2.8做了一些练习，下面是我的模型：

class Incident < ActiveRecord::Base
  attr_accessible :category, :user, :status, :reference, :location
  belongs_to :user
  has_one :location
  accepts_nested_attributes_for :location

  validates_presence_of :location, :user, :category


end

class Location < ActiveRecord::Base
  attr_accessible :latitude, :longitude, :street
  belongs_to :incident
end

这是我的测试：

require 'spec_helper'

describe Incident do
  before (:each) do
    @user = create(:user, :name => "user1")
    @incident_data = {:category => "House Break in", :user => @user,
                      :location => {:latitude => "-28.1940509", :longitude => "28.0359692",
                                    :street => "abc name"}}
  end
  describe "After create Incident successfully" do
    it "should create location" do
      incident = Incident.create(@incident_data)

      expect(incident.location.latitude).to eq("-28.1940509")
    end
  end
end

我想要做的是在创建事件对象时自动创建位置对象。但是测试失败了，原因如下：

失败/错误：事件 = Incident.new(@incident_data)

ActiveRecord::AssociationType 不匹配：

位置（#70156311891820）预期，得到哈希（#70156307112200）

有任何想法吗？

它明确表示 location 应该是 的实例Location，而不是Hash. 你有

:location => {:latitude => "-28.1940509", :longitude => "28.0359692",
                                :street => "abc name"}

但是，一旦您使用嵌套属性，它应该是location_attributes（请参阅NestedAttributes 文档）：

:location_attributes => {:latitude => "-28.1940509", :longitude => "28.0359692",
                                :street => "abc name"}

或者你可以只创建Location对象

:location => Location.new(:latitude => "-28.1940509", :longitude => "28.0359692",
                                :street => "abc name")
