ruby-on-rails - 尝试在 Rails lib 目录中自动加载类时出现 NoMethodError

Question

我有以下内容：

# lib/devblog_extensions.rb
module DevblogExtensions
  class Time
    def self.random_date
      # implementation ...
    end
  end
end

# spec/factories/posts.rb
FactoryGirl.define do
  factory :post do
    release_date Time.random_date # NoMethodError occurs
  end
end

然后在config/application.rb我有：

config.autoload_paths += %W(#{config.root}/lib)

但是当我跑步时，rspec我仍然得到一个NoMethodError，所以我错过了什么？谢谢！

您可能缺少包括

# spec/factories/posts.rb
include DevblogExtensions

FactoryGirl.define do
  factory :post do
    release_date Time.random_date # NoMethodError occurs
  end
end

更新：快速修复

# lib/devblog_extensions.rb
module DevblogExtensions
end

class Time
  def self.random_date
    Time.now
  end
end
