【问题描述】:
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对话(消息)的列表。但是,该方法仅输出消息的主题。我需要显示邮件的发件人以及主题。如何编辑此输出以显示发件人姓名?
SQL 表显示发件人姓名未存储在会话表中,而是通过通知表中的通知(一对多)存储在通知表中。我尝试使用<%= conversation.notifications.sender_id %>,但出现以下错误:
NoMethodError in Conversations#index
undefined method `notifications' for nil:NilClass
我可以向对话控制器和视图添加什么以显示对话的用户和主题?
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
