【问题描述】：
我正在使用 Backand 来存储我的数据。我有一个对象，事件，它引用另一个对象，位置。
{
"name": "events",
"fields": {
"eventCommentsId": {
"collection": "comments",
"via": "eventId"
},
"tags": {
"collection": "events_tags",
"via": "event"
},
"users": {
"collection": "users_events",
"via": "event"
},
"name": {
"type": "string"
},
"date": {
"type": "datetime"
},
"time": {
"type": "datetime"
},
"info": {
"type": "text"
},
"locationId": {
"object": "locations"
}
},
{
"name": "locations",
"fields": {
"events": {
"collection": "events",
"via": "locationId"
},
"name": {
"type": "text"
},
"geo": {
"type": "point"
}
}
}
当我尝试显示事件的位置时，我只能获取 locationID 的值。我想要位置的实际名称，而不是 id。我该怎么做？
<ion-list>
<ion-item class="item item-thumbnail-left" ng-repeat="event in events" type="item-text-wrap" href="#/event-detail/{{event.id}}">
<h2>{{event.name}}</h2>
<p><i class="ion-location"></i> {{event.locationId.name}}</p>
<ion-option-button class="button-assertive" ng-click="deleteEvent(event.id)">
Delete
</ion-option-button>
</ion-item>
</ion-list>

.service('EventService', function ($http, Backand) {
var baseUrl = '/1/objects/';
var objectName = 'events/';
function getUrl() {
return Backand.getApiUrl() + baseUrl + objectName;
}
function getUrlForId(id) {
return getUrl() + id;
}
getEvents = function () {
return $http.get(getUrl());
};
addEvent = function(event) {
return $http.post(getUrl(), event);
}
deleteEvent = function (id) {
return $http.delete(getUrlForId(id));
};
getEvent = function (id) {
return $http.get(getUrlForId(id));
};
return {
getEvents: getEvents,
addEvent: addEvent,
deleteEvent: deleteEvent,
getEvent: getEvent
}
})
.controller('FeedCtrl', ['$scope', '$ionicModal', '$ionicSideMenuDelegate', 'EventService', function($scope, $ionicModal, $ionicSideMenuDelegate, EventService) {
$scope.events = [];
$scope.input = {};
function getAllEvents() {
EventService.getEvents()
.then(function (result) {
$scope.events = result.data.data;
});
}
$scope.addEvent = function() {
EventService.addEvent($scope.input)
.then(function(result) {
$scope.input = {};
getAllEvents();
});
}
$scope.deleteEvent = function(id) {
EventService.deleteEvent(id)
.then(function (result) {
getAllEvents();
});
}
getAllEvents();
}])
