FactoryGirl使い方メモ

model定義

group.rb

class Group < ActiveRecord::Base
  has_many :events
  has_many :members
end

event.rb

class Event < ActiveRecord::Base
  has_many :groups
end

has_manyの定義方法

group_event.rb

FactoryGirl.define do
  factory :seq_group, class: Group do
    sequence(:name) { |n| "group #{n}"}
    sequence(:description) {|n| "description #{n}"}
    sequence(:img_url) {|n| "http://test.com/#{n}.jpg"}
  end

  factory :group_event, class: Group do
    sequence(:name) { |n| "group #{n}"}
    sequence(:description) {|n| "description #{n}"}
    sequence(:img_url) {|n| "http://test.com/#{n}.jpg"}

    events {
      [FactoryGirl.create(:seq_event)]
    }
  end
end

重複を除く為のparent

• 「parent: :seq_group」を使ったのですが、もっと便利な書き方があります。
• ネストして定義しちゃえば、継承出来ます

group_event.rb

FactoryGirl.define do
  factory :seq_group, class: Group do
    sequence(:name) { |n| "group #{n}"}
    sequence(:description) {|n| "description #{n}"}
    sequence(:img_url) {|n| "http://test.com/#{n}.jpg"}

    factory :group_event do
      events {
        [FactoryGirl.create(:seq_event)]
      }
    end
  end
end

配列・リストの作り方

group_event.rb

FactoryGirl.define do
  factory :group_event, class: Group do
    members {
      FactoryGirl.create_list(:seq_user, 10)
    }
  end
end
