javascript - 使用 sails js 删除记录时 Mongo 出错

Question

我是 sails.js 的新手，尝试使用 mongodb 和 sails.js 创建 CRUD，从记录列表中删除记录时遇到一些问题。在这里我附上我的所有工作文件，请指导我

// controller file function 
removePost: function(req, res)
    {

        var id = req.query.id;
        //var id = req.param("id", null);
        console.log(id);
        sails.log(id);
        Dashboard.remove({'_id' : id } , function(error){
            console.log("Come in dataase" + error);
        })
        res.redirect('dashboard/index');

    }

这是我的 ejs 文件

 <div class="col-sm-9">
            <h3>Latest Post</h3>
            <% result.forEach( function( model){ %>
            <br>
            <div class="media">
               <i class="fa fa-check-square-o pull-left fa-2x"></i>
               <a href="/dashboard/removePost?id=<%=model.id%>"><i class="fa fa-trash-o pull-left fa-2x"></i></a>
               <div class="media-body">
                  <h3 class="media-heading"> <%=model.title %> </h3>
                  <%=model.description %>
               </div>
            </div>
            <% }); %>

         </div>

这是我的路线

module.exports.routes = {

  '/': {
    view: 'homepage'
  },
  '/about':{
    view: 'about/index'
  },
  'get /register': 'RegisterController.index',
  'post /register/create' : 'RegisterController.create',
  'get /dashboard/create' : 'DashboardController.create',
  'get /Dashboard': 'DashboardController.index',
  'get /dashboard/removePost:id': 'DashboardController.removePost'
};

当点击删除链接时，它会调用上面的 Controller 函数removePost()

终端错误显示:

任何人的帮助将不胜感激提前致谢

在 Controller 中，您正在使用Dashboard.remove()，但此方法不存在。 Use Dashboard.destroy().exec() instead .

Dashboard.destroy({'_id' : id }).exec(function(err){
    console.log('The record has been deleted');
})
