将数据发送到parse.com并更新角度$范围 [英] Sending data to parse.com and update angular $scope

问题描述

我将数据发送到parse.com上的Class，我想运行此函数并更新 $ scope ，而无需重新加载视图。

要创建一个 Program ，运行下面的函数可以正常工作，但它有时不会在创建新程序后更新视图，它需要一个页面刷新（当整个函数被调用，如底部所示 - getProgrammes（）;

<$ p （）;

var programmesArray = [];
var QueryProgramme = Parse.Object（）; $ p $ getProgrammes = function（）{
$ ionicLoading.show （Program）;
var query = new Parse.Query（QueryProgramme）;

query.equalTo（userId，userId）;
query.find（ {
success：function（results）{
for（var i = 0; i< results.length; i ++）{
var object = results [i];

var programmeData = {title：object.get（'programmeTitle'），
id：object.id，
练习：object.get（'exerciseData'）
};

programmesArray.push（programmeData）;
}

$ scope.programmes = programmesArray;
$ scope。$ apply（）;
$ ionicLoading.hide（）;
}，
错误：函数（错误）{
alert（'您没有任何程序 - 请创建一个'）;
}
}）
};

getProgrammes（）;


我想我可能会使用 $ scope.apply（） - 因此不可靠。协助使用正确的函数来自动更新 $ scope 会很好。

基本上我只是引用parse-angular.js文件，然后在我的应用程序中包含依赖项，例如：

  angular.module（'app'，[
'parse-angular'，
]）; 
  

然后我随时使用Parse查询，并且他们能够正确地使用 $范围和 $ apply 。该库只是对Parse方法做一些简单的包装，以使异步调用遵守angular的规则。

I am sending data to a Class at parse.com, I would like to run this function and update the $scope without having to reload the view.

To create a Programme running the function below works fine, however it sometimes does not update the view following creating a new programme and it requires a page refresh (when the whole function is called as seen at the bottom - getProgrammes();

getProgrammes = function() {
$ionicLoading.show();

var programmesArray = [];
var QueryProgramme = Parse.Object.extend("Programme");
var query = new Parse.Query(QueryProgramme);

query.equalTo("userId", userId);
query.find({
success: function(results) {
  for(var i=0; i < results.length; i++) {
    var object = results[i];

    var programmeData = { title : object.get('programmeTitle'), 
                          id : object.id,
                          exercises : object.get('exerciseData')
                        };

    programmesArray.push(programmeData);
  }

  $scope.programmes = programmesArray;
  $scope.$apply();
  $ionicLoading.hide();
   },
   error: function(error) {
   alert('You do not have any Programmes - please create one');
   }
 })
};

getProgrammes();

I think I may be hacking this by using $scope.apply() - therefore making it unreliable. Assistance on the correct function to use in order to automatically update $scope would be great.

解决方案

I've been using a library found here:

https://github.com/brandid/parse-angular-patch

Essentially I just reference the parse-angular.js file, and then include the dependency in my app, e.g.:

angular.module('app', [
  'parse-angular',
]);

Then I just use Parse queries anytime I like and they participate correctly with $scope and $apply. The library just does some simple wrapping on the Parse methods to make the async calls obey the rules of angular.
