Fabrication gem让我无法运行 rails 控制台，因为它抱怨我用它创建的工厂模型已经在我的应用程序/模型中定义。

例如，我有一个Issue模型app/models，看起来像：

class Issue
  include Virtus.model

  attribute  :id,      String, :default => ""
  attribute  :summary, String, :default => ""

end

我正在创建此模型的示例，同时进行spec/factories/issue.rb如下测试：

Fabricator(:issue) do
  id      "00001"
  summary "test summary"
end

无论如何，我认为 Rails 控制台吓坏了，因为问题有两个定义。但是，我的 rspec 测试和应用程序都运行良好。

我得到的具体错误是：

如何rails console在为我的 rspec 测试实现 Fabrication 的同时加载？

当您尝试制造某些东西时，制造会自动加载定义的制造商。它还会检查以确保您不会意外定义相同的制造商两次，因为这可能会导致您的代码库中出现令人困惑的问题。您可能会看到这种情况，因为您的应用程序中的某些内容正在加载制造商两次。

值得注意的是，如果您实际上不尝试制造某些东西，则制造根本不会尝试加载制造商。如果您在运行控制台时立即看到这一点，则很可能您的代码库中有 2 个实例，其中制造商正在其自己的进程之外加载。

我还回答了反对制造本身的问题：https ://github.com/paulelliott/fabrication/issues/302#issuecomment-330935726
