我目前正在编写Michael的Rails教程。在本章中，我得到了4个不同的错误，并将非常感谢您帮助解决它们。

我做了一个mess..ugh。任何和所有的帮助都是非常感谢！

编辑:而且，我对所有这些都很陌生，所以如果我应该删除那些测试绿色的旧测试，请告诉我。我不确定这些失败的测试是否因为我做错了什么而变红，或者当我阅读本教程时，我应该删除它们。谢谢!

Answer 1

在你的routes.rb里

get 'login'   => 'sessions#new'
get 'login'   => 'sessions#create'

看上去怪怪的。我想应该是

get 'login'   => 'sessions#new'
post 'login'  => 'sessions#create'
