Question

我有这段代码：

FactoryGirl.define do
  factory :gimme_a_hash, class: Hash do
    one 'the number 1'
    two 'the number 2'
  end
end

它返回一个看起来像的哈希：

1.9.3p448 :003 > FactoryGirl.build : gimme_a_hash
 => {:one=>"the number 1", :two=>"the number 2"}

如何创建一个工厂，将带有字符串化数字的哈希作为键返回？

理想情况下，我希望返回以下哈希值：

 => { "1"=>"the number 1", "2"=>"the number 2"}

谢谢！

Answer 1

我不确定是否还有其他办法。但这是一种做法

  factory :gimme_a_hash, class: Hash do |f|
    f.send(1.to_s, 'the number 1')
    f.send(2.to_s, 'the number 2')

    initialize_with {attributes.stringify_keys}
  end

<强>结果：

1.9.3p194 :001 > FactoryGirl.build(:gimme_a_hash)
 => {"1"=>"the number 1", "2"=>"the number 2"}

<强>更新

默认情况下，factory_girl初始化给定类的对象，然后调用setter来设置值。在这种情况下，a=Hash.new然后a.1 = 'the_number_1'无法正常工作

通过说initialize_with {attributes}，我要求它Hash.new({"1" => "the number 1", "2" => "the number 2"})

您正在寻找attributes_for方法。

factory :user do
  age { Kernel.rand(50) + 18 }
  email 'fake@example.com'
end

FactoryGirl.attributes_for(:user)
=> { :age => 31, :email => "fake@example.com" }

FactoryGirl.attributes_for(:user).stringify_keys
=> { "age" => 31, "email" => "fake@example.com" }

如何定义一个返回带有弦键的Hash的FactoryGirl工厂？
