Parse.Query find() 方法未返回任何内容

Question

我查看了有关此主题的其他堆栈溢出帖子，看起来我运行发现了一些新东西。有问题的查询方法不在用户 table 上。

当我在 mBuilding object 中查询 distance 或许多其他列时，我得到了未定义的信息，尽管这些列显然在那里，我将列标题复制并粘贴到函数中以检查拼写。据我所知，唯一有效的查询是使用 objectId 获取并查找。 equalTo、select、withinMiles（至少）返回 null/undefined 结果。更有趣的是，即使 find() 之前的查询未定义，它也会适当地影响查找结果。这真是令人费解。

这是怎么回事？我的代码：

angular.module('startupApp')
.controller('warrantyCtrl', function ($scope) {
    $scope.Building = {};

    $scope.Building.parseUserId = Parse.User.current().id;
    console.log($scope.Building.parseUserId);
    var consumer = Parse.User.current();
    var user = Parse.Object.extend("User");
    var warrantys = Parse.Object.extend("warranty");
    var mBuilding = new Parse.Query(warrantys);
    var consumerQuery = new Parse.Query(Parse.User);

    $scope.consumerBuilding = function() {
        var location = consumer.get("location");
        mBuilding.withinMiles("location", location, "distance");
        mBuilding.find({
            success: function (proximalwarrantys){
                console.log(proximalwarrantys);
            }
        })
    }
    $scope.consumerBuilding();

});

问题是传递给 withinMiles 函数的距离应该是一个数字而不是 "distance":

withinMiles(key, point, maxDistance)

Add a proximity based constraint for finding objects with key point values near the point given and within the maximum distance given. Radius of earth used is 3958.8 miles.

Parameters:

{String} key The key that the Parse.GeoPoint is stored in.

{Parse.GeoPoint} point The reference Parse.GeoPoint that is used.

{Number} maxDistance Maximum distance (in miles) of results to return. Returns:

{Parse.Query} Returns the query, so you can chain this call.
