FactoryGirl覆盖关联对象的属性 [英] FactoryGirl override attribute of associated object

问题描述

这可能是愚蠢的简单，但我找不到任何地方的例子。

This is probably silly simple but I can't find an example anywhere.

我有两个工厂：

FactoryGirl.define do
  factory :profile do
    user

    title "director"
    bio "I am very good at things"
    linked_in "http://my.linkedin.profile.com"
    website "www.mysite.com"
    city "London"
  end
end

FactoryGirl.define do 
  factory :user do |u|
    u.first_name {Faker::Name.first_name}
    u.last_name {Faker::Name.last_name}

    company 'National Stock Exchange'
    u.email {Faker::Internet.email}
  end
end

我想要做的是覆盖某些用户属性，当我创建一个配置文件：

What I want to do is override some of the user attributes when I create a profile:

p = FactoryGirl.create(:profile, user: {email: "[e-mail]"})

或类似的东西，但我不能得到正确的语法。错误：

or something similar, but I can't get the syntax right. Error:

ActiveRecord::AssociationTypeMismatch: User(#70239688060520) expected, got Hash(#70239631338900)

我知道我可以先创建用户，然后将其与关联轮廓做到这一点，但我认为必须有一个更好的办法。

I know I can do this by creating the user first and then associating it with the profile, but I thought there must be a better way.

或者这将工作：

p = FactoryGirl.create(:profile, user: FactoryGirl.create(:user, email: "[e-mail]"))

不过，这似乎过于复杂。有没有更简单的覆盖关联的属性的方法吗？
什么是正确的语法为这个？

but this seems overly complex. Is there not a simpler way to override an associated attribute? What is the correct syntax for this??

推荐答案

据FactoryGirl的创建者之一，你不能传递动态参数的关联助手（<一个href=\"http://stackoverflow.com/questions/10434572/pass-parameter-in-setting-attribute-on-association-in-factorygirl\">Pass参数在FactoryGirl 上设置的关联属性）。

According to one of FactoryGirl's creators, you can't pass dynamic arguments to the association helper (Pass parameter in setting attribute on association in FactoryGirl).

然而，你应该能够做这样的事：

However, you should be able to do something like this:

FactoryGirl.define do
  factory :profile do
    ignore do
      user_args nil
    end
    user { build(:user, user_args) }

    after(:create) do |profile|
      profile.user.save!
    end
  end
end

然后就可以调用它就像你想：

Then you can call it almost like you wanted:

p = FactoryGirl.create(:profile, user_args: {email: "[e-mail]"})
