ruby - 如何让 rspec 不显示数据库查询而只显示带有 rails_12factor 的点？

Question

ruby: 2.0
rails: 3.2.17
rspec: 2.14.8
Database: mysql

rspec spec 用于仅输出点。

当我推送到 Heroku 并且最近添加了 rails_12factor gem 来绕过它时，我收到了弃用警告。但是，现在在本地运行规范时，我会得到每个事务的详细数据库输出。
当我需要它时这是一个很好的选择，否则它会产生很多不需要和分散注意力的输出。

所以我想要一个将它用于 Heroku 而不是本地的选项。

请注意，这不会通过使用格式化程序来解决，例如

rspec spec -fd

此外，如果出现错误，在这种冗长程度下，错误几乎总是滚出当前页面...

Answer 1

我们也看到了这一点，它是由 rails_12factor gem 生成的，它可以被抑制，通常只需确保 gem 仅在生产组中，就像这样:

group :production do
  gem 'rails_12factor'
end

rails_12factor 的依赖项之一是另一个名为 rails_stdout_logging 的 gem，它会导致您看到的输出。
