Question

我正在尝试过滤从FindAll返回的数据，因为我只想要来自某个提供商的数据

// Data coming back from API
{
  "-KDinaItb7lkHpai-DlG": {
    "email": "johns@test.com",
    "name": "John Smith",
    "notes": "John is a great employee and is the best",
    "phone": "215-543-9830",
    "provider": "-KDhzbilOvv7Evuc5S_X"
  },
  "-KDjS0cCxFWQctcwXg0V": {
    "email": "amanda@test.com",
    "name": "Amanda Harrington",
    "notes": "Amanda is a great employee",
    "phone": "215-543-9830",
    "provider": "-KDiokWebdhTNKTORWwn"
  },
  "-KDyf7pU_PyxRQSgFB59": {
    "email": "lguy@test.com",
    "name": "Larry Guy",
    "notes": "He is a funny guy",
    "phone": "702-454-2397",
    "provider": "-KDhzbilOvv7Evuc5S_X"
  }
}

// In the route
let providerId = model.get('provider').get('id');

this.store.findAll('employee').then(function(results) {
  let prov = results.filterBy('provider', providerId);

  console.log(prov);
});

当控制台日志发生时，它返回一个空数组。我认为它是因为ID而不是看嵌套对象。有人有任何想法吗？

好的，你的哈希看起来很奇怪。属性名称不应该是一些生成的哈希值。

代码应该是这样的。我假设你在数组中的索引0上有1个包装器对象。

var filteredEmployees_promise = this.store.findAll('employee').then(function(results) {
   var filteredResults = [];
   Object.keys(Results[0]).forEach(key => {
     var filteredObj = Results[0][key][providerId];
     if(Ember.isPresent(filteredObj) {
        filteredResults.pushObject(filteredObj)
     }
   });
   return filteredResults;
});

以后

filterEmployees_promise.then(employees => { // Custom stuff })

Ember Data FilterBy
