Где я должен создать свои общие ассоциации FactoryBot?

/ 18 декабря 2018

У меня есть модель User, для которой требуется_100 *.Используя FactoryBot, я хочу создать нескольких пользователей, которые используют одну и ту же компанию.Я увидел некоторый совет , который я интерпретировал как предложение создать объекты Компании в моем блоке FactoryBot.define do, которые я могу использовать в качестве атрибутов для своих пользователей: 

# In spec/factories/companies.rb
FactoryBot.define do
  factory :company do
    name { 'MyCompany' }
  end
end


# In spec/factories/users.rb
FactoryBot.define do
  company1 = FactoryBot.create(:company)  # this will be shared by several users

  factory :user1 do
    first_name { 'Joe' } 
    last_name { 'Smith' } 
    company_id { company1.id }
  end

  factory :user2 do
    first_name { 'Sam' } 
    last_name { 'Smith' } 
    company_id { company1.id }
  end
end

Это работаетво-первых, кроме случаев, когда мне нужно заново создать базу данных с нуля в тестовом контейнере с rake db:create.Когда запускается rake, он, кажется, инициализирует мои фабрики, и шаг FactoryBot.create(:company) пытается выполнить, и нет схемы db на месте, поэтому он терпит неудачу: 

$ RAILS_ENV=test  bundle exec rake db:rebuild
rake aborted!
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR:  relation "companies" does not exist
LINE 8:                WHERE a.attrelid = '"companies"'::regclass
                                          ^
:               SELECT a.attname, format_type(a.atttypid, a.atttypmod),
                     pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod,
                     c.collname, col_description(a.attrelid, a.attnum) AS comment
                FROM pg_attribute a
                LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum
                LEFT JOIN pg_type t ON a.atttypid = t.oid
                LEFT JOIN pg_collation c ON a.attcollation = c.oid AND a.attcollation <> t.typcollation
               WHERE a.attrelid = '"companies"'::regclass
                 AND a.attnum > 0 AND NOT a.attisdropped
               ORDER BY a.attnum

Это заставляет меня думать, что япытаясь создать их не в том месте.

Где лучше всего настроить общие ассоциации, такие как company1, для моих тестовых данных, чтобы они возникали после правильной инициализации моего приложения и перед выполнением моего набора тестов?

FWIW, вотстек ошибок:

Когда вы создаете объекты таким способом - они создаются каждый раз, когда фабрики инициализируются, независимо от того, будут ли они использоваться в конкретном тестовом прогоне или нет.

Обычно лучше иметь независимые фабрики и явно указыватьв ваших тестах вы хотите, чтобы два пользователя из одной компании: 

 let(:company){ create :company }
 let(:user1){ create :user, company: company }
 let(:user2){ create :user, company: company }

Для случаев, когда вам нет дела до точного отношения и вы просто хотите повторно использовать какое-то действительное значение и избежать каскадных отношений - есть create_default обходной путь вtest-prof камень (подробнее здесь )
