Angular app not updating (dirty-checking) after async call to firebase


Angular app not updating (dirty-checking) after async call to firebase

Hope that helps You'll need to manually fire the digest since you are outside of Angular's scope by the time the callback is fired. There are a couple different strategies. Using $apply() is one:
code :
        ref.on("value", function(snapshot) {
            var posts = snapshot.val();
            for (var post in posts) {
                $scope.posts.push(posts[post]);
            }
            $scope.$apply(); // RUN DIGEST HERE
        }, function (errorObject) {

it fixes the issue You can add to handle this.
It will work with multiple input elements, but see the note at the end.
code :
<div ng-controller="MyCtrl">
    <form name="form">  
        <input name='myInput' ng-model='model.myInput'>
        <div ng-show='form.myInput.$dirty'>Dirty</div>

        <!-- 1. Add `ng-form="myForm"` directive. -->
        <span ng-form="myForm"
              ng-repeat='field in email'>
            <input ng-model="field[email.name]" name={{email.name}} />
            {{field[email.name]}}

            <!-- 2. Reference the named parent -> `myForm.$dirty` -->
            <div ng-show="myForm.$dirty">It's dirty!</div>
        </span>
    </form>
</div>

it should still fix some issue boindiil's directive based solution works but has a flaw: it stops working if form's $setPritine is executed manually. This can be solved by adding an extra line that wipes out the method behavior for the input:
code :
angular.module('myApp', []).directive('ignoreDirty', [function() {
    return {
    restrict: 'A',
    require: 'ngModel',
    link: function(scope, elm, attrs, ctrl) {
      ctrl.$setPristine = function() {};
      ctrl.$pristine = false;
    }
  }
}]);

will help you I have a directive attached to an input field that calls $compile(element)(scope); in its Link method. Everything works well, except when trying to use the following: , You need to use compile, instead of link like so:
code :
  app.directive('inputDataType', ['$compile', function ($compile) {
      var compileFn = function(element) {
          element.removeAttr('input-data-type');

          // Add pattern
          element.attr('ng-pattern', '^[a-zA-Z0-9]+$');

          // Make input field required
          element.attr('required', 'true');

          // Compile to attach new directives / pattern / required
          var fn = $compile(element);

          return function(scope){
              fn(scope);
          };
      };

      return {
          restrict: 'A',
          scope: false,
          terminal: true,
          priority: 1001,
          compile: compileFn
      };
  }]);

To fix the issue you can do If you modify an object that is known by the hibernate session, it will automatically be saved by hibernate when session is flushed. I would advise against this because in your code you don't know if you are using hibernate or another ORM. Additionally, if your object is not in the session when you modify it, it will not be saved. So always call save explicitely to make sure your object is saved.
