我在回复与 Rails 4 中的 Mailboxer gem 的对话时遇到问题。关于这个 gem 的文档并不多，或者我可能只是经验不足，但我已经坚持了一段时间现在。

view/conversations/index：（ 显示所有当前用户的对话列表）

<% @conversations.each do |conversation| %>
<%= link_to conversation.subject, reply_conversation_path(conversation.id) %>
<%= conversation.updated_at.strftime("%a, %m/%e/%Y %I:%M %p") %>
<%= link_to "Move to Trash", {:controller => "conversations", :action => 
    "trash", :id => conversation.id}, :title=> "Move to Trash", :method=>'post' %>
<% end %>

当我单击link_to上面视图中的第一个时，我收到路由错误：No route matches [GET] "/conversations/68/reply".

我希望让它呈现以下视图，并将正确的对话传递给它：

view/messages/_form/ （用于回复现有对话）

Reply:
<%= form_for :message, url: :conversation do |f| %>
<%= f.text_area :body %>
<%= f.submit "Send Message", class: 'btn btn-primary' %>
<%= submit_tag 'Clear Reply Box', type: :reset, class: 'btn btn-danger' %>
<% end %>

路线：

resources :users
root to: 'profiles#index'

resources :messages do
  member do
      post :new
  end
end
resources :conversations do
  member do
      post :reply
      post :trash
      post :untrash
  end
  collection do
      get :trashbin
      post :empty_trash
  end
end

对话控制器：

class ConversationsController < ApplicationController
before_filter :authenticate_user!
helper_method :mailbox, :conversation
def index
    @conversations ||= current_user.mailbox.inbox.all
end

def reply
    current_user.reply_to_conversation(conversation, *message_params(:body, :subject))
    redirect_to conversation
end

def trashbin
    @trash ||= current_user.mailbox.trash.all
end

def trash
    conversation.move_to_trash(current_user)
redirect_to :conversations
end

def untrash
    conversation.untrash(current_user)
redirect_to :back
end

def empty_trash
    current_user.mailbox.trash.each do |conversation|
        conversation.receipts_for(current_user).update_all(:deleted => true)
    end
redirect_to :conversations
end

private

def mailbox
    @mailbox ||= current_user.mailbox
end

def conversation

    @conversation ||= mailbox.conversations.find(params[:id])
end

def conversation_params(*keys)
    fetch_params(:conversation, *keys)

end

def message_params(*keys)
    fetch_params(:message, *keys)
end

def fetch_params(key, *subkeys)
    params[key].instance_eval do
        case subkeys.size
            when 0 then self
            when 1 then self[subkeys.first]
            else subkeys.map{|k| self[k] }
        end
    end
end
end

消息控制器：

class MessagesController < ApplicationController

# GET /message/new
def new

    @request = Request.find(params[:request])
    @message = current_user.messages.new
    @user = @request.user
end

# POST /message/create
def create

@user = User.find(params[:user])
@body = params[:body]
@subject = params[:subject]

current_user.send_message(@user, params[:body], params[:subject])
flash[:notice] = "Message has been sent!"
redirect_to :conversations
end
end

相关的 rake 路线：

                    users GET    /users(.:format)                     users#index
                      POST   /users(.:format)                     users#create
             new_user GET    /users/new(.:format)                 users#new

为了让您了解我是如何做到这一点的，我一直在关注本教程：http: //jamestansley.com/2014/02/22/customizing-the-mailboxer-ruby-gem-2/

我猜我需要更多地研究路由，但我需要在周末结束之前完成，所以非常感谢你的帮助。

如果我遗漏了任何内容，这是我的 github 存储库： https ://github.com/portOdin/GoFavorIt-Heroku/tree/stackflow/app 。

更新：

正如我在下面提到的，我解决了这个问题，尽管我现在有另一个问题。

'nil:NilClass'的未定义方法`[]'

在此处输入图像描述

这个问题变得相当大，所以我可能会稍后再打开另一个，除非你能在这里帮助我。

我换了行：

 <%= link_to conversation.subject, reply_conversation_path(conversation.id) %>

和：

<%= link_to "Reply To Conversation", {:controller => "conversations", :action => 
"reply", :id => conversation.id}, :title=> "Reply To Conversation", :method=>'post' %>

我刚刚复制并修改了“移至废纸篓”链接。不确定这是否是最好的方法，但它现在工作正常。
