Utilizing the $resource service to access and modify resources on my API has been a challenge.
An issue arises when the ng-model-bound object's value is set to empty - the bound element is removed from the object. This results in the missing element during resource saving and passing of data.
angular.module('myApp', [])
.controller('myCtrl', function($scope, $resource) {
var Person = $resource('persons/:id.json', {id: @id});
$scope.data = Person.get({id:123});
});
For instance, setting data.name to '' in the given template:
<div ng-controller="myCtrl">
<input type="text" ng-model="data.name" />
<input type="button" ng-click="data.$save()" value="Save" />
</div>
The presence of the element in the passed data during saving is crucial as it influences whether the API will update the attribute value to empty or retain its current value.
