AngularJS - PUT method not working (404 error)

问题

I'm new to AngularJS and I have trouble to update an object via REST. I'm using a PHP/Mysql Backend (Slim Framework).
I'm able to retrieve (GET), create (POST) a new object but not to edit (PUT) one. Here's the code:

my Form:

<form name="actionForm" novalidate ng-submit="submitAction();">
  Name: <input type="text" ng-model="action.name" name="name" required>
  <input type="submit">
</form>

My service:

var AppServices = angular.module('AppServices', ['ngResource'])
AppServices.factory('appFactory', function($resource) {
  return $resource('/api/main/actions/:actionid', {}, {
    'update': { method: 'PUT'},
  });
});

app.js

var app = angular.module('app', ['AppServices'])
app.config(function($routeProvider) {
  $routeProvider.when('/main/actions', {
    templateUrl: 'partials/main.html',
    controller: 'ActionListCtrl'
  });
  $routeProvider.when('/main/actions/:actionid', {
    templateUrl: 'partials/main.html',
    controller: 'ActionDetailCtrl'
  });
  $routeProvider.otherwise({redirectTo: '/main/actions'});
});

controllers.js:

function ActionDetailCtrl($scope, $routeParams, appFactory, $location) {
  $scope.action = appFactory.get({actionid: $routeParams.actionid});
  $scope.addAction = function() {
    $location.path("/main/actions/new");
  }
  $scope.submitAction = function() {
    // UPDATE CASE
    if ($scope.action.actionid > 0) {
      $scope.action = appFactory.update($scope.action);
      alert('Action "' + $scope.action.title + '" updated');
    } else {
      // CREATE CASE
      $scope.action = appFactory.save($scope.action);
      alert('Action "' + $scope.action.title + '" created');
    }
    $location.path("/main/actions");
  }
}

In Slim, in api/index.php, I've got these routes and functions defined:

$app->get('/main/actions', 'getActions');
$app->get('/main/actions/:actionid',    'getAction');
$app->post('/main/actions', 'addAction');
$app->put('/main/actions/:actionid', 'updateAction');

When I create a new "action", everything is working as expected. But when I try to edit an existing one, I've got this error:

PUT http://project.local/api/main/actions 404 Not Found

The action is not updated (although the alert message "Action xxx updated" is displayed)

Is it an issue with my routeProvider setting ? I guess the PUT url misses the id at the end...

I precise that if I try to simulate the PUT request with POSTMan-Chrome-Extension for example, everything is working well (PUT http://project.local/api/main/actions/3 returns the expected data)

回答1:

After reading more carefully, the problem is indeed that you don't send the id in the url when you do the update request. Furthermore, the way you call update / save is not quite what is intended with resource. After you have created a resource, you call the save / update methods on the instance, not as a factory function. You can also bind properties of the instance to the params in the url, so you don't have to specify them on each call:

AppServices.factory('appFactory', function($resource) {
  return $resource('/api/main/actions/:actionid', {actionid : '@actionid'}, {
    'update': { method: 'PUT'},
});

The second parameter of resource tells angular which properties it should use to populate the url parameters. so the get operation stays the same:

$scope.action = appFactory.get({actionid: $routeParams.actionid});

and the update is now:

$scope.submitAction = function() {
  // UPDATE CASE
  if ($scope.action.actionid > 0) {
    $scope.action.$update()
  } else {
    $scope.action.$save();  
  }
}

Since you used angular-cellar as a basis, I should probably check and see if I can improve this ...
