Question

好的，这是我发布到stackoverflow的第一个问题。我对编码很陌生，过去3个月一直在学习Ruby on Rails。我的代码可能有一些问题，但在这里。

基本上我正试图让用户发帖。我正在使用Devise进行注册，所有这些都有效。但是当我在标题视图中创建“创建帖子”的链接时，它告诉我我没有路由匹配=＆gt;即使我认为它存在。我错过了一些我认为很小的东西，但是在我尝试做到的所有调试中，我想我可能在整个过程中弄乱了别的东西。下面附有我的routes.rb代码，我的post_controller文件和我的布局视图文件。抱歉所有的漫无边际，我不能很简洁。有人看错了什么吗？如果您需要查看其他代码，请告诉我

_header.html.erb

    <% if user_signed_in? %>
    Signed in as <%= current_user.username %>. Not you?
    <%= link_to "Logout", destroy_user_session_path, :method => :delete, %>
    <%= link_to "Create Post", new_user_post_path %>
    <%= link_to "Search", posts_index_path %>
    <%= link_to "Show All", posts_show_path %>

的routes.rb

  #devise_for :users 
  devise_for :users do get '/users/sign_out' => 'devise/sessions#destroy' end

  match '/users/:user_id/posts/new',  :to => 'posts#new'

  resources :users do
   resources :posts, :only => [:new, :create, :show, :index, :destroy]
  end

  match '/contact', :to => 'pages#contact'
  match '/about',   :to => 'pages#about'
  match '/help',    :to => 'pages#help'
  match '/safety',  :to => 'pages#safety'
   match '/privacy', :to => 'pages#privacy'

  get 'posts/index'
  get 'posts/show'
  get 'posts/post'

  match 'posts/search',   :to => 'posts#search'

  root :to => 'pages#home'

posts_controller

  def create
if signed_in?
  @user = current_user.posts.build(params[:user][:post])
  if @user.save
    flash[:success] = "Thanks for creating your post! " +
    redirect_to new_user_post_path(@post)
  else
    render 'new'

  def new   
   @title = "Create Post"
   @post = Post.new
  end

Answer 1

尝试在控制台中输入rake routes，然后检查您要查找的路线是否存在。请注意，订单也很重要。

Answer 2

应该是

<%= link_to "Create Post", new_user_post_path(current_user) %>

Answer 3

我认为这是因为这个论点！在您的路由文件中，您似乎正在传递：user_id。在你的链接尝试传递该ID。希望它有所帮助...

＆lt;％= link_to“create Post”，new_user_post_path（current_user.id）％＆gt;

另外我建议尝试重命名路径并使用它。我知道它不是正确的方法，但仍然。我遇到了类似的问题并通过这样做解决了!!;）

希望它有所帮助！

我得到No route matches {：action =＆gt;“new”，：controller =＆gt;“posts”}，即使它不在我的routes.rb文件中。救命？
