Question

我正在尝试添加一个指向我的帖子＆gt;索引页面的链接，该链接可让人们向帖子的创建者发送直接消息（使用简单私人消息）。

目前我有一个指向/ messages / new的链接来执行此操作，但这不起作用 - 当我尝试访问/ messages / new时，我的应用程序中出现以下错误。

我想用更好的方法替换/ messages / new（在下面的POSTS＆gt; INDEX文件中）的链接。如果您有任何想法，请告诉我！

**NoMethodError in Messages#new**

Showing /Users/fkhalid2008/loand/app/views/messages/new.html.erb where line #1 raised:

undefined method `user_messages_path' for #<#<Class:0x12a77f198>:0x12a76dce0>

Extracted source (around line #1):

1: <% form_for @message, :url => user_messages_path(@user) do |f| %>
2:   <p>
3:     To:<br />
4:      <%= f.text_field :to %>

附加信息：应用程序本身就像Gumtree.com，用户来创建帖子（例如卖我的车），人们回复我发送消息（通过简单的Pvt消息插件）。

谢谢！

消息模型

class Message < ActiveRecord::Base

is_private_message

attr_accessor :to

end

的routes.rb

Mysalary::Application.routes.draw do

resources :messages do
   collection do
     post :delete_selected
     end
   end

resources :users
resources :profiles
resources :pages
resources :posts

get "pages/home"
get "pages/about"
get "pages/legal"
get "pages/feedback"

root :to => 'posts#new'

end

消息控制器

class MessagesController < ApplicationController

before_filter :set_user

def index
if params[:mailbox] == "sent"
  @messages = @user.sent_messages
else
  @messages = @user.received_messages
end
end

def show
@message = Message.read_message(params[:id], current_user)
end

def new
@message = Message.new

if params[:reply_to]
  @reply_to = @user.received_messages.find(params[:reply_to])
  unless @reply_to.nil?
    @message.to = @reply_to.sender.login
    @message.subject = "Re: #{@reply_to.subject}"
    @message.body = "\n\n*Original message*\n\n #{@reply_to.body}"
  end
end
end

def create
@message = Message.new(params[:message])
@message.sender = @user
@message.recipient = User.find_by_login(params[:message][:to])

if @message.save
  flash[:notice] = "Message sent"
  redirect_to user_messages_path(@user)
else
  render :action => :new
end
end

def delete_selected
if request.post?
  if params[:delete]
    params[:delete].each { |id|
      @message = Message.find(:first, :conditions => ["messages.id = ? AND (sender_id = ? OR recipient_id = ?)", id, @user, @user])
      @message.mark_deleted(@user) unless @message.nil?
    }
    flash[:notice] = "Messages deleted"
  end
  redirect_to :back
end
end

def set_user
 @user = User.first
end
end

Answer 1

你routes.rb没有定义路径user_messages_path，这很简单：）

如果你想要嵌套的restful路由，你需要像

这样的东西

resources :users do
  resources :messages
end

Answer 2

只需使用

<% form_for @message do |f| %>
<% end %>

Rails 3项目中未定义的方法“用户消息路径”
