grails - 在Gson中渲染少量模型

Question

是否可以将少量对象发送到gson渲染 View ？
我试图在 Controller 中使用:

respond trainings, [status: OK, view:"trainingsByClients", model: [myVariable: "test", anotherVariable: 123]]

并在 gson View 中:

model {
    Iterable<Training> trainingList
    String myVariable
}

json {
    myVariable myVariable
    trainings tmpl.training(trainingList ?: [])
}

并回应:

{
  "myVariable": null,
  "trainings": [
    {
      "id": 3,
      "name": "test t",
      "numberOfAbsentClients": 0,
      "startDate": "2016-11-20T09:00:00+0000",
      "numberOfClients": 2,
      "section": {
    "id": 1,
    "name": "test sec"
      }
    },
    {
      "id": 10,
      "name": "test 2",
      "numberOfAbsentClients": 0,
      "startDate": "2016-11-09T11:00:00+0000",
      "numberOfClients": 2,
      "section": {
    "id": 2,
    "name": "sec 2"
      }
    }
  ]
}

Answer 1

好的，我找到了解决方案:

    render(view: "trainingsByClients", model: [trainingList: trainings, myVariable: "asdg"])

所以我们应该使用 render而不是 respond。响应未正确添加其他模型对象。
