ruby-on-rails - 与 FactoryGirl 的关联抛出未定义的方法

Question

我有一个属于许多事件的事件。每当我使用 rSpec 测试我的工厂时，我都会收到错误消息。

我的 测试 是:

it "has valid factory" do
    expect(FactoryGirl.build(:activity)).to be_valid
end

和 错误 给出的是:

  1) Activity has valid factory
     Failure/Error: expect(FactoryGirl.build(:activity)).to be_valid
     NoMethodError:
       undefined method `client=' for #<Activity:0x6cbb800>
     # C:in `object'
     # ./spec/models/activity_spec.rb:5:in `block (2 levels) in <top (required)>

自从我加了 association :client 就一直这样到我的 事件工厂 :

FactoryGirl.define do
    factory :activity do
        title "Activity"
        start_date {Date.parse('2013-05-13 12:00:00')}
        end_date {Date.parse('2013-05-13 12:15:00')}
        pictogram_id "1"
        association :client
    end
end

并且客户端本身也通过了所有测试。同一个工厂:( clients.rb )

FactoryGirl.define do
    factory :client do
        name "Client name"
        background "#FFFFFF"
        birthdate {15.years.ago}
    end
end

由于这不是测试数据库准备/克隆问题，我正在用我的 的相关部分更新帖子。 schema.rb

  create_table "activities", force: true do |t|
    t.string   "title"
    t.datetime "start_date"
    t.datetime "end_date"
    t.integer  "pictogram_id"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "activities", ["pictogram_id"], name: "index_activities_on_pictogram_id"

  create_table "activities_clients", id: false, force: true do |t|
    t.integer "activity_id"
    t.integer "client_id"
  end

  add_index "activities_clients", ["activity_id"], name: "index_activities_clients_on_activity_id"
  add_index "activities_clients", ["client_id"], name: "index_activities_clients_on_client_id"

  create_table "clients", force: true do |t|
    t.string   "name"
    t.string   "avatar"
    t.date     "birthdate"
    t.string   "background"
    t.integer  "group_id"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

知道为什么该协会无法 ehm .. 关联吗？

如果您的数据库架构更改尚未在测试数据库上运行，则通常会发生这种情况。确保在最近的迁移后运行“rake db:test:prepare”。
