单个文档的三向数据绑定，而不是使用Meteor和Angular进行的收集

Question

According to the documentation, it is possible to bind a collection to the Angular Scope with

 angular.module('socially', ['angular-meteor']);

  angular.module('socially').controller('PartiesListCtrl', ['$scope', function ($scope) {
    $scope.parties = $meteor.collection(Parties);
  }]);
}

This works really well when having a list of items I want to display.

But now I want to edit one of those items, which means I don´t have any collection to bind, but just a single document

 angular.module('socially', ['angular-meteor']);

  angular.module('socially').controller('PartiesListCtrl', ['$scope', function ($scope) {
    $scope.party = $meteor.collection(Parties.findOne({my query});
  }]);
}

I need a 3-Way-Binding to have changes from the client immediately saved to the database.

How is that possible for just one document?

Answer 1

simply pass this into our angularjs function.

<div ng-repeat="party in parties">
      <span ng-click="editparty(this)">{{party.location}}</span>
 </div>

in angularjs function this (which is now obj ) will contain the party object.

$scope.editparty = function(obj){

    obj.party.location = "England"; //edit party object

    //pass to our database...

    obj.party = $meteor.collection(Parties.findOne({my query});

});
