编辑:感谢您的答复，我尝试了下面列出的所有方法，但现在还是很幸运。如果输入localhosts/posts/new，它将带我到表单，但是当我从导航栏中单击时，该链接不起作用。我已经更新了代码，并包含了我的 rake 路结果。
我是 ruby 的新手，正在研究一个教程，但是我的链接之一无法正常工作，也不知道发生了什么。
我创建新帖子的导航链接无法将我带到正确的页面，当我单击指向“posts_path”的链接时，页面不会更改。
我可以通过在地址栏中输入/posts/new来创建新帖子，但是当我单击导航栏上的“新帖子”链接时，页面不会更新(尽管url显示/posts)。任何想法如何解决这个问题？

最佳答案
Rails从顶部到底部扫描路由，即route.rb 。只要找到匹配的路由，就会执行相应的 Controller #action ，其余所有路由都将被跳过(找到匹配项后的路由)。
在这种情况下，路线会发生冲突，因此波纹管变更也可以正常工作。
config/routes.rb
Rails.application.routes.draw do
get 'sessions/new'
root 'static_pages#home'
get '/search', to: 'static_pages#search'
get '/login', to: 'sessions#new'
#get '/posts', to: 'posts#new', as: 'new_post' #not required as resources :posts will do the job in last line
post '/login', to: 'sessions#create'
delete '/logout', to: 'sessions#destroy'
get '/signup', to: 'users#new'
get 'users/new'
get 'static_pages/home'
get 'posts/new', to: 'posts#new', as: 'posts_new_path' #Made changes here according to helper used in view 'posts_new_path'
get 'sessions/new'
resources :users
resources :account_activations, only: [:edit]
resources :password_resets, only: [:new, :create, :edit, :update]
resources :posts, only: [:new, :create, :destroy]
end
