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”。我不明白这一点。听起来它正在尝试创建 /users/1 或第一个用户，但我只是使用表单来创建微博。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：

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 %>
另外，这里是 microposts_controller.rb
class MicropostsController < ApplicationController
before_filter :correct_user, only: :destroy
def create
@micropost = current_user.microposts.build(params[:micropost])
if @micropost.save
flash[:success] = "Micropost created!"
redirect_to root_path
else
@feed_items = []
render 'static_pages/home'
end
end
def new
@micropost = Micropost.new(params[:micropost])
end
def show
@micropost = Micropost.find(params[:id])
@microposts = Micropost.where(:user_id => @user.id)
@purchases = @microposts.where(:kind => "purchase")
@sales = @microposts.where(:kind => "sale")
end
和 users_controller.rb
class UsersController < ApplicationController
before_filter :signed_in_user,
only: [:index, :edit, :update, :destroy, :following, :followers]
before_filter :correct_user, only: [:edit, :update]
before_filter :admin_user, only: :destroy
def index
@users = User.paginate(page: params[:page])
end
def show
@user = User.find(params[:id])
@microposts = @user.microposts.paginate(page: params[:page])
end
def new
@user = User.new
end
def create
@user = User.new(params[:user])
if @user.save
sign_in @user
flash[:success] = "Welcome to the Sample App!"
redirect_to @user
else
render 'new'
end
end
def edit
end
def update
if @user.update_attributes(params[:user])
flash[:success] = "Profile updated"
sign_in @user
redirect_to @user
else
render 'edit'
end
end
