Base URL of Rails app in Model

由 本秂侑毒 提交于 2021-01-26 06:49:40
问题 In order to be able to see if a User has shared my page on Facebook, I want to be able to create this kind of URLs: http://graph.facebook.com/?id=http://stylehatch.co/some_unique_user_token Where http://stylehatch.co would need to be my base URL. I am thinking on having a method in the User model that will build and return that URL, but I can't access root_url from within my model. How can I get the base URL of my application from a Model? Say if my urls look like this: http://myapp.com/users

“Controller, Action, Model” not all code paths return a value

由 江枫思渺然 提交于 2021-01-20 12:22:07
问题 I am really confused by this error "not all code paths return a value" on my action PostResponse. I have stared at my model, controller and view for hours and I think I have all paths covered. Of course the project won't build, so I can't debug further. My action // POST: /Questions/ViewQuestion/5 [HttpPost] [ValidateAntiForgeryToken] public ActionResult PostResponse([Bind(Include = "UserId,QuestionID,Answer,Source,Status,DateStamp")] Response response) { if (ModelState.IsValid) { db

sails的简单配置以及controller的使用

由 对着背影说爱祢 提交于 2020-11-28 04:20:25
因为前段时间的一个项目,用到了sails,那么上回已经介绍过了sails的安装和如何创建项目, 没看过的童鞋可以使劲戳这里 http://my.oschina.net/codingBingo/blog 既然已经可以创建项目了,那么接下来就是项目的配置以及使用啦, 因为sails是基于nodejs的开发的服务端工具,所以用它来开发一些数据计算比较少的项目是相当的快的,而且nodejs天生的异步回调机制可以很好地避免高并发的问题,难怪阿里的人这么喜欢它, 咳咳,不扯了,下面主要介绍 一下sails的controller层是如何使用使用的. 首先我们先在根目录下的views文件夹中新建一个user.ejs文件,这是view层用的 <div> <%=userName%> </div> 然后在config文件中找到route.js文件,打开编辑, '/':{[ views:'homePage' }, 'get /userName':{ controller:user, action:sendUserName } 接下来新建controller文件,在api目录下找到controller文件夹,创建文件UserController.js文件 modules.exports={ sendName:function(req,res){ res.views('pages/user',{
