I am wanting to use $resource to make a RESTful update on our server but the view get's updated as soon as the user clicks when I would like it to not update until the server sends a response. I am using a controller with a service layer that uses a rest resource.
Template:
<tbody>
<tr ng-repeat="user in users">
<td><button class="radius tiny button"
ng-click="toggleUserActive(user)"
ng-bind="user.active ? 'Disable User' : 'Enable User'">
</button>
</td>
<tr>
</tbody>
Controller:
angular.module('admin', ['admin.AdminService'])
.controller('adminCtrl', function ($scope, adminService) {
$scope.toggleUserActive = function(user){
adminService.toggleUserDisabled(user).then(function(response){
// Want the update to happen here
user.active = response;
});
};
});
Service:
angular.module('admin.AdminService', ['rest'])
.service('adminService', function AdminService(UserRest){
this.toggleUserDisabled = function(user) {
user.active = !user.active;
return UserRest.update(user).$promise.then(function(result){
return result.active;
});
};
});
Rest service:
angular.module('rest', ['config','ngResource'])
.factory('RestEndpoint', function (apiEndpoint) {
return {
users: apiEndpoint + '/admin/users/:username'
};
})
.factory('UserRest', function ($resource, RestEndpoint){
return $resource(RestEndpoint.users, {username:'@username'},{
update: {
method: 'PUT'
}
});
});
How can I code this where the view does not update until response has made it back?
You could use something like this in your view
ng-show="user.active"
which will show once the $scope is updated with that new data.
I have not used the rest service as you are at the moment, but doing something similar with API calls, I used the $q and promises. Can you use the $q and promises in the controller, so the controller codes does not continue until the responses are received?
.controller('MyController', function($scope, $http, $q) {
var JSON1 = $http.get('example1.json');
var JSON2 = $http.get('example2.json');
$q.all([JSON1, JSON2]).then(function(results) {
...
});
})
