Factorybot 无法识别任何属性——"method missing" 个错误

Question

我最近升级了一堆宝石，从那以后我不能运行 rails 服务器、控制台或 rspec。

这是我看到的错误日志：

部分升级包括将 rails 升级到 5.2.3，这迫使我从 new_framework_defaults.rb 文件中删除了这一行：

# Do not halt callback chains when a callback returns false. Previous versions had true.
ActiveSupport.halt_callback_chains_on_return_false = false

我猜这与它有关？

编辑：工厂代码如下。这个确切的代码在升级 gems 之前 100% 工作：

FactoryBot.define do
  factory :book do
    name "my songbook"
  end
end

Answer 1

FactoryBot 更改了语法。现在，它在为变量赋值（甚至是静态值）时需要一个块。将您的代码更改为：

FactoryBot.define do
  factory :book do
    name { "my songbook" }
  end
end

请参阅他们的文档 Defining Factories。
