在我的应用程序; 当我提交表单时,我收到此错误:
LoadError at /questions
Unable to autoload constant Message, expected /app/models/message.rb to define it
它指向控制器中的create动作Questions:
@message = current_user.messages.new(:subject => "You have a question from #{@question.sender_id}"`
消息模型:
class Mailboxer::Message < ActiveRecord::Base
attr_accessible :notification_id, :receiver_id, :conversation_id
end
我必须使用rmagick,它不允许我启动rails服务器.我已经在这里阅读了谷歌,到目前为止,这些解决方案都没有提供帮助.图书馆出了问题,我不知道如何修复它.
如果有人有修复这个确切问题的建议,将非常感激.

我正在设置javascript以在大于767的屏幕上显示728x90的广告网络横幅代码.如果屏幕宽度较小,它将仅显示300x250横幅代码.当我添加以下代码时,它在网络和移动设备上都没有显示,只是一个空白区域.如果有帮助,我在wordpress内部工作.

我将ActiveAdmin添加到我的应用程序中,更新了一些宝石,现在我undefined method `link_to_function'在查看用户显示页面时得到了一个.我有will_paginate宝石,我添加了初始化程序,所以没有冲突.

该错误指向/app/helpers/will_paginate_helper.rb上的行:
