我正在一个具有用户到用户友谊功能的项目中工作。 我不知道我的路线发生了什么，但这是我在html中的输出：
/friends.Friends->这应该是链接“ friends”，但是当我单击它时什么也没有发生
和
/friend_requests.Friend%20requests->它也应该是链接“ friend_requests”
Rails.application.routes.draw do
root "events#index"
devise_for :users
devise_scope :user do
get "login", :to => "devise/sessions#new"
get "logout", :to => "devise/sessions#destroy"
get "signup", :to => "devise/registrations#new"
end
resources :users, :only => [ :index, :show ]
resources :friendships, :only => [:create, :update, :destroy]
get '/friend_requests', to: 'friend_requests#index'
get '/friends', to: 'friends#index'
resources :events
end
这就是我的看法：
<%= link_to friends_path "Friends" %>
<br>
<%= link_to friend_requests_path "Friend requests" %>
这是包执行耙路径的输出

当我通过输入localhost：300 / friends或localhost：300 / friend_requests访问时，它可以工作 但是当我尝试使用链接到时，它就坏了：/

参数的顺序不正确。
从Docs
link_to（name = nil，options = nil，html_options = nil，＆block）public
使用一组选项创建的URL创建给定名称的锚元素。请参阅文档中url_for的有效选项。也可以传递String而不是options哈希，它会生成一个锚元素，该锚元素使用String的值作为链接的href。使用：back符号而不是选项哈希将生成指向引荐来源网址的链接（如果不存在引荐来源网址，则会使用JavaScript反向链接）。如果将nil作为名称传递，则链接本身的值将成为名称。
名称应作为第一个参数传递，而您将其作为第二个参数传递。
尝试像这样交换参数：
<%= link_to "Friends" ,friends_path %>
<br>
<%= link_to "Friend requests", friend_requests_path %>

您在视图中的link_to助手不正确，
link_to（name = nil，options = nil，html_options = nil，＆block）
<%= link_to "Friends", friends_path %>
<br>
<%= link_to "Friend requests", friend_requests_path %>
