angularjs - angular-meteor 根据参数查找 MongoDb 集合并返回

Question

我正在尝试使用 Meteor 和 Angular.js 的组合在我的 MongoDb 中获取某个地址的警告

在我的html文件中，我正在做

<div ng-controller = "myController as myCtrl">
{{myCtrl.warnings}}
{{myCtrl.getWarnings("123 Test Street, TestCity, TestState")}}
</div>

在我的 app.js 文件中:

Warnings = new Mongo.Collection("Warnings");

if (Meteor.isClient) {
  var app = angular.module('ffprototype', [ 'angular-meteor' ]);

  app.controller('myController', ['$window','$meteor', function($window, $meteor) {

    this.warnings = $meteor.collection(Warnings);

    this.getWarnings = function(findByAddress){
        Warnings.find({address: findByAddress}).fetch();
    }
  }]);
}

我的 mongoDb 集合:

{
    "_id": "3ixgxEMZDWGtugxA7",
    "address": "123 Test Street, TestCity, TestState",
    "warning": "Warning 1"
}
{
   "_id": "HZH5FvCD5driBYSJz",
    "address": "123 Test Street, TestCity, TestState",
    "warning": "Warning 2"
}

html 网页的输出显示了整个警告集合(感谢 {{currentDispatch.warnings}}，但对于 {{currentDispatch.getWarnings("123 Test Street , TestCity, TestState")}}

您应该使用 $meteor.object为此

this.getWarnings = function(findByAddress){
  $meteor.object(Warnings, { address: findByAddress }, false); // passing false here to not update the collection from changes in the client
}
