Question

我正处于学习ember.js的初始阶段。我正在尝试一个应用程序，并且在从控制器中存在的对象引用另一个对象时卡住了。

  {{#each employee in controller}}
  <tr>
  <td class="span2"><input type="checkbox" style="margin-left : 110px;"/></td>
  <td class="span2">{{#linkTo 'employee' employee}}{{employee.empId}}{{/linkTo}}</td>
  <td class="span2">{{employee.name}}</td>
  <td class="span2">{{employee.age}}</td>
  <td class="span2">{{employee.dob}}</td>
  <td class="span2">{{employee.gender}}</td>
  <td class="span2">{{employee.doj}}</td>
  <td class="span2">{{#linkTo 'employee' employee}}{{employee.mgrId}}{{/linkTo}}</td>
  <td class="span2">{{employee.package}}</td>
  <td class="span2">{{employee.address}}</td>
  <td class="span2">{{employee.phone}}</td>
  <td> <button {{action "deleteEmployee" employee}}> Delete </button></td>
  {{/each}}

这里我试图使用id ..

来获取经理的详细信息

索引路由的代码是：

App.Router.map(function() {
    this.resource('employee',{
        path: "/employee/:employee_id"},
        function() {
            this.route('edit');
        }
    );
    this.route('allEmployees');
  // put your routes here
});

App.AllEmployeesRoute = Ember.Route.extend({
    model: function() {
        //console.log(param.patient_id);
        var employees = [];
        for(var employee_id in App.Employees)
        {
            employees.push(App.Employees[employee_id])
        }
        return employees;

    }
});


App.Employee = Ember.Object.extend({
        "empId":null,
        "name":null,
        "age":null,
        "dob":null,
        "gender":null,
        "doj":null,
        "mgrId":null,
        "package":null,
        "address":null,
        "phone":null
    });

// Code for event handling
App.AllEmployeesController = Ember.ArrayController.extend({
        deleteEmployee:function(employee){
            var employees = this.get('model');
            for(var i=0; i<employees.length;i++)
            {
                if(employees[i].empId === employee.empId)

                employees.removeAt(i);

            }

        console.log("deleting "+employee.empId);
        }   
    }
);

那么如何在余烬中完成？

编辑：

JSON记录结构：

App.Employees = {
    "1" : App.Employee.create({
        "id" : "1",
        "empId" : "emp1",
        "name" : "Employee 1", 
        "age" : "23",
        "dob" : "17/12/89",
        "gender" : "male",
        "doj" : "9/1/12",
        "mgrId" : "emp6",
        "package" : "300000",
        "address" : "address 1",
        "phone" : "9999999999"
    }),
    "2" : App.Employee.create({
        "id" : "2",
        "empId" : "emp2",
        "name" : "Employee 2", 
        "age" : "24",
        "dob" : "18/1/90",
        "gender" : "female",
        "doj" : "20/2/13",
        "mgrId" : "",
        "package" : "350000",
        "address" : "address 2",
        "phone" : "9437543985"

    }),
    "3" : App.Employee.create({
        "id" : "3",
        "empId" : "emp3",
        "name" : "Employee 3", 
        "age" : "25",
        "dob" : "19/2/91",
        "gender" : "male",
        "doj" : "12/12/11",
        "mgrId" : "emp2",
        "package" : "300000",
        "address" : "address 3",
        "phone" : "3454395943"
    }), }

您可以使用needs API访问特定控制器中的其他控制器。

needs: 'manager',
managerBinding: 'controllers.manager'

从那里，如果manager是您想要的对象，则可以通过控制器中的this.get('manager')和相应模板中的manager引用它。

在模板中引用不同的对象
