目前,我在集合视图中显示集合时遇到问题.该集合是现有模型的属性,如此(伪代码)

ApplicationVersion { Id: 1, VersionName: "", ApplicationCategories[] }

所以基本上ApplicationVersion有一个名为ApplicationCategories的属性,它是一个javascript数组.目前,当我渲染与ApplicationCategories相关联的集合视图时,不会呈现任何内容.如果我在Chrome的javascript调试器中调试,似乎尚未填充类别(因此我假设还没有提取ApplicationVersion).这是我目前的代码

ApplicationCategory模型,集合和视图

ApplicationModule.ApplicationCategory = Backbone.Model.extend({
    urlRoot:"/applicationcategories"
});

ApplicationModule.ApplicationCategories = Recruit.Collection.extend({
    url:"/applicationcategories",
    model:ApplicationModule.ApplicationCategory,

    initialize: function(){
        /*
         * By default backbone does not bind the collection change event to the comparator
         * for performance reasons.  I am choosing to not preoptimize though and do the
         * binding.  This may need to change later if performance becomes an issue.
         * See https://github.com/documentcloud/backbone/issues/689
         *
         * Note also this is only nescessary …

我正在创建一个基本的POST JSON api端点.我想对它进行单元测试,并希望确保我在Play框架中正确地进行测试.到目前为止,我使用Guice进行依赖注入,使用JUnit进行单元测试库.

这是我的控制器代码:

public class NotificationController extends Controller {

  private RabbitQueueService _rabbitQueueService;

  @Inject
  public NotificationController(RabbitQueueService service) {
    _rabbitQueueService = service;
  }

  @BodyParser.Of(BodyParser.Json.class)
  public Result post() {
    ObjectMapper mapper = new ObjectMapper();
    Notification notification;

    try {
      JsonNode notificationJsonNode = Controller.request().body().asJson();
      notification = mapper.readValue(notificationJsonNode.toString(), 
                                      Notification.class);
      _rabbitQueueService.push(notification);
      return Results.created(notificationJsonNode, "UTF-8");

    } catch (JsonParseException e) {
      e.printStackTrace();
    } catch (JsonMappingException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }

    return Results.badRequest();
  }
}

我的RabbitQueueService代码:

public class RabbitQueueService {

  private Channel _channel;
  private …
