我在我的Rails应用程序中使用Mailboxer(https://github.com/ging/mailboxer)gem来处理用户之间的私人消息。根据文档,我使用= render mailbox.inbox
显示登录用户的所有会话(消息)列表。但是,该方法仅输出消息的主题。我需要显示消息的发件人以及主题。如何编辑此输出以显示发件人姓名?
SQL表显示发件人名称未存储在会话表中,而是存储在notification_on_conversation_id(一对多)的通知表中。我尝试使用<%= conversation.notifications.sender_id %>
,但我收到以下错误:
NoMethodError in Conversations#index
undefined method `notifications' for nil:NilClass
我可以将哪些内容添加到会话控制器和视图中以显示会话的用户和主题?
谢谢!
对话控制器:
class ConversationsController < ApplicationController
before_filter :authenticate_user!
helper_method :mailbox, :conversation
def create
recipient_emails = conversation_params(:recipients).split(',')
recipients = User.where(email: recipient_emails).all
conversation = current_user.
send_message(recipients, *conversation_params(:body, :subject)).conversation
redirect_to conversation
end
def reply
current_user.reply_to_conversation(conversation, *message_params(:body, :subject))
redirect_to conversation
end
def trash
conversation.move_to_trash(current_user)
redirect_to :conversations
end
def untrash
conversation.untrash(current_user)
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

sender_id
对于任何会话,您都可以使用以下方式检索收据: @receipts = conversation.receipts_for
