我有一个应用程序，用户可以在其中发布微博。但是在表格中输入一个并按帖子，它说没有路线匹配[POST]“/users/1”。这是我当前的 routes.rb 文件。

SampleApp::Application.routes.draw do
  resources :users do
    resources :comments

    member do
      get :following, :followers
    end
  end
  resources :sessions, only: [:new, :create, :destroy]
  resources :microposts, only: [:create, :destroy] do
    resources :comments

  end
  resources :relationships, only: [:create, :destroy]

  root to: 'static_pages#home'

  match '/signup',  to: 'users#new'
  match '/signin',  to: 'sessions#new'
  match '/signout', to: 'sessions#destroy', via: :delete

  match '/help',    to: 'static_pages#help'
  match '/about',   to: 'static_pages#about'
  match '/contact', to: 'static_pages#contact'


  # The priority is based upon order of creation:

这是我运行 rake 路由时的输出：

                signup        /signup(.:format)                                     users#new
                signin        /signin(.:format)                                     sessions#new

               contact        /contact(.:format)                                    static_pages#contact

我想我真正需要的是让 [POST] users/:id 路由到 microposts#create，但我不知道它的语法。

ps 如果我添加帖子“users/:id”，：controller =>“users/update”，我会收到错误消息：

ArgumentError (missing :action):
  config/routes.rb:4:in `block (2 levels) in <top (required)>'
  config/routes.rb:2:in `block in <top (required)>'
  config/routes.rb:1:in `<top (required)>'

这是与控制器交谈的形式（我认为）

<%= form_for :micropost do |f| %>

  <div class="field no-indent">
    <%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
    <%= hidden_field_tag 'micropost[kind]', "purchase" %>
  </div>
  <%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>

在您的 form_for 中，您只需要指定 url。我认为这应该有效。<%= form_for :micropost, :html => {:method => :post, :url => microposts_path} 做 |f| %>

  <div class="field no-indent">
    <%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
    <%= hidden_field_tag 'micropost[kind]', "purchase" %>
  </div>
  <%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>

也让我知道什么是 html 输出。在 form_for :html 参数以 hashmap 形式给出，其中 key 是表单属性，value 是属性值。

谢谢
