Question

我无法加载表单，不知道为什么会发生这种情况。

问题：当我尝试加载表单（/ messages / new）时，我得到一个空白页面，没有错误消息。

问题的原因：我认为问题是消息和用户之间的链接没有正确建立，这就是为什么表单没有正确加载，但不知道如何解决它

背景：我目前通过POSTS / INDEX文件（下面附带）访问该表单，但我认为这是错误的，因为每个用户都应该有一个唯一的链接......例如。如果我点击John创建的帖子的“联系”按钮，该消息应该转到John，依此类推给其他用户。我正在使用Simple Private Messaging插件。

感谢任何反馈！

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"

  @messages = @user.sent_messages
else
  @messages = @user.received_messages
end
end

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

@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)

      @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
