Question

我有两个模特，Show和Venue。场地has_many :shows。节目belongs to :venue。它们的定义如下：

class Venue < ActiveRecord::Base
  validates :name, presence: true

  has_many :shows
end

class Show < ActiveRecord::Base
  validates :show_date, presence: true
  validates :doors_open, presence: true
  validates :dinner_starts, presence: true
  validates :dinner_ends, presence: true
  validates :show_starts, presence: true
  validates :show_ends, presence: true
  validates :venue, presence: true

  belongs_to :venue, foreign_key: 'venue_id'
end

with schema：

ActiveRecord::Schema.define(version: 20150218021116) do

  create_table 'shows', force: :cascade do |t|
    t.date 'show_date'
    t.time 'doors_open'
    t.time 'dinner_starts'
    t.time 'dinner_ends'
    t.time 'show_starts'
    t.time 'show_ends'
    t.datetime 'created_at',    null: false
    t.datetime 'updated_at',    null: false
    t.integer 'venue_id'
  end

  add_index 'shows', ['venue_id'], name: 'index_shows_on_venue_id'

  create_table 'venues', force: :cascade do |t|
    t.string 'name'
    t.datetime 'created_at', null: false
    t.datetime 'updated_at', null: false
  end

end

和工厂：

FactoryGirl.define do
  factory :show do
    show_date Faker::Date.forward 30
    doors_open Faker::Time.forward 30, :evening
    dinner_starts Faker::Time.forward 30, :evening
    dinner_ends Faker::Time.forward 30, :evening
    show_starts Faker::Time.forward 30, :evening
    show_ends Faker::Time.forward 30, :evening

    association :venue, factory: :venue
  end
end

FactoryGirl.define do
  factory :venue do
    name Faker::Address.street_name
  end
end

我试图通过传递有效属性来测试我的shows_controller，我遇到的问题是FactoryGirl的attributes_for方法没有返回venue_id字段。这是我运行puts attributes_for

时得到的结果

{:show_date=>Tue, 03 Mar 2015, :doors_open=>2015-03-12 17:44:45 -0500, :dinner_starts=>2015-02-25 20:35:13 -0600, :dinner_ends=>2015-03-08 19:58:18 -0500, :show_starts=>2015-02-25 21:25:55 -0600, :show_ends=>2015-03-17 21:21:57 -0500}

我在这里设置错了吗？为什么我没有收到venue_id？

Answer 1

由于您试图让FactoryGirl通过对关联的引用生成外键，我想知道has_and_belongs_to_many关联是否导致问题。看起来您在这里的关系是Venue只是has_many显示的; Venue不依赖于（AKA“属于”）一个节目的存在（场地表中没有外观的表演）。看看更改关联是否清除了FactoryGirl的内容。

FactoryGirl attributes_for方法不返回外键
