你可以看到3行代码：

t.debug create(:ticket)
t.debug create(:ticket)
t.debug build(:invalid_ticket)

输出相同的body: "Deserunt et accusantium totam ab autem ad."

为什么会出现以及如何修复？

Answer 1

因为Faker ::句子依赖于rand(6) 请看以下代码段：

2.1.5 :001 > rand(6)
 => 5 
2.1.5 :002 > rand(6)
 => 3 
2.1.5 :003 > rand(6)
 => 3 
2.1.5 :004 > rand(6)
 => 4 
2.1.5 :005 > rand(6)
 => 3 
2.1.5 :006 > rand(6)
 => 1

6使用的默认值为Faker::Lorum.sentence，获得相同种子的几率非常高。

这是Faker的来源：

def sentence(word_count = 4, supplemental = false, random_words_to_add = 6)
  words(word_count + rand(random_words_to_add.to_i).to_i, supplemental).join(' ').capitalize + '.'
end

运气不好，你继续得到同样的句子。您可以做的是覆盖参数并获得更高的种子值以增加随机化。

Answer 2

问题出在 factories / tickets.rb 而是像

那样设置Ticket factory

工厂：机票做       customer_name {Faker :: Name.name}
      customer_email Faker :: Internet.email
      主题Faker :: Lorem.sentence
      身体Faker :: Lorem.sentence

您应该使用大括号将值传递给属性：

customer_name { Faker::Name.name }
customer_email { Faker::Internet.email }
subject { Faker::Lorem.sentence }
body { Faker::Lorem.sentence

factory_girl创建重复值
