找不到$resource.get()抛出函数错误

Question

我是ionic新手，这是我的工厂文件代码

 .factory('getLocations', ['$resource', 'constants', function ($resource,      constants) {
return $resource(constants.server + constants.routes.getLocation, {id : '@id'});
  }])

这里的url类似于../rest/search/:id

控制器的调用如下所示：

$scope.locations = getLocations.get({id : '1'});

但是当我调用rest URL时，我在控制台中看到下面的错误：

 ionic.bundle.js:26799 TypeError: V is not a function

我遗漏了什么？我正在传递url中定义的参数，但仍然显示此错误。请帮帮忙。
