ruby-on-rails - Hartl 在 config.serve_static_files 上的 sample_app 警告，并且测试已经定义

Question

我正在尝试测试 Hartl 的 sample_app，这是我在运行 bundle exec rake test 后收到的消息:

DEPRECATION WARNING: The configuration option `config.serve_static_assets` has been renamed to `config.serve_static_files` to clarify its role (it merely enables serving everything in the `public` folder and is unrelated to the asset pipeline). The `serve_static_assets` alias will be removed in Rails 5.0. Please migrate your configuration files accordingly.

这是 test/integration/users_profile_test.rb 文件。

end

我只是按照教程中的说明进行操作，所以我不知道自己做错了什么。如果您需要其他文件，我会发布它们。gem 版本可能不同还是其他原因？

Answer 1

该教程已过时。您的输出消息显示了两个问题。

1。弃用警告

弃用警告表明 serve_static_assets 是旧名称，新名称是 serve_static_files。 Rails 对名称和方法进行了稳步改进，因此这是一个非常常见的警告。

编辑 sample_app/config/environments/test.rb。

来自这里:

config.serve_static_assets  = true

对此:

config.serve_static_files  = true

2。测试重新定义

第二个问题是你的测试文件有问题。

查看错误消息并查看关于您的代码的第一行:

/home/aki/sample_app/test/models/user_test.rb:10:in `<class:UserTest>'

你能把这个文件贴出来吗？

错误信息是说你定义了一个方法两次。

验证

要验证您的更改是否到位，cd 到您的 Rails 根目录。

查找包含旧 Assets 设置的文件名:

find -type f | xargs grep -l 'serve_static_assets' 

查找包含方法名称文本的文件名:

find -type f | xargs grep -l 'test.*should.*be.*valid' 

查看出现的任何文件，看看是否仍有代码需要更改，或者是否有另一个 UserTest 类中的测试“应该有效”。
