i have a problem, i cannot get values (added with $form->addField) from form in CRUD. I just get what's in the model, but there just isn't extra values...
MODEL:
class Model_Admin extends Model_Table {
public $table ='admin';
function init(){
parent::init();
$this->addField('name')->mandatory('Name required');
$this->addField('email')->mandatory('Email required');
$this->addField('password')->type('password')->mandatory('Password required');
}
}
On page i create extended CRUD and add two more fields:
$adminCRUD = $this->add('MyCRUD');
$adminCRUD->setModel('Admin');
if($adminCRUD->isEditing('add')){
$adminCRUD->form->addField('line','test2','TEST LINE');
$adminCRUD->form->addField('DropDown', 'appfield','Manages Applications')
->setAttr('multiple')
->setModel('Application');
}
Extended CRUD:
class MyRUD extends CRUD {
function formSubmit($form)
{
//var_dump($form);
var_dump($form->get('test2'));
var_dump($form->get('appfield'));
try {
//$form->update();
$self = $this;
$this->api->addHook('pre-render', function () use ($self) {
$self->formSubmitSuccess()->execute();
});
} catch (Exception_ValidityCheck $e) {
$form->displayError($e->getField(), $e->getMessage());
}
}
}
I get null for $form->get('test2') or $form->get('appfield'). I checked whole $form object and there isn't values from test2.. Somwhere in the process gets lost (or droped), how to get it in extended CRUD?
Thanks in advance!

We have four specific products with a massive amount of variants. When running the Product Indexer we run out of memory because of these products.
So we want to exclude these specific products from the Product Indexer Job.
My first approach was to use the ProductIndexerEvent, but the event is dispatched at the end of the handle() method :
(vendor/shopware/core/Content/Product/DataAbstractionLayer/ProductIndexer.php:187),
which is probably too late.
What is the best approach to implement that behaviour?
I would advise against excluding products from being indexed. There's business logic relying on the data being indexed.
If you're confident in what you're doing and know about the consequences, you could decorate the ProductIndexer service.
<service id="Foo\MyPlugin\ProductIndexerDecorator" decorates="Shopware\Core\Content\Product\DataAbstractionLayer\ProductIndexer">
<argument type="service" id="Foo\MyPlugin\ProductIndexerDecorator.inner"/>
</service>
In the decorator you would have to deconstruct the original event, filter the WriteResult instances by excluded IDs and then pass the reconstructed event to the decorated service.
class ProductIndexerDecorator extends EntityIndexer
{
const FILTERED_IDS = ['9b180c61ddef4dad89e9f3b9fa13f3be'];
private EntityIndexer $decorated;
public function __construct(EntityIndexer $decorated)
{
$this->decorated = $decorated;
}
public function getDecorated(): EntityIndexer
{
return $this->decorated;
}
public function getName(): string
{
return $this->getDecorated()->getName();
}
public function iterate($offset): ?EntityIndexingMessage
{
return $this->getDecorated()->iterate($offset);
}
public function update(EntityWrittenContainerEvent $event): ?EntityIndexingMessage
{
$originalEvents = clone $event->getEvents();
if (!$originalEvents) {
return $this->getDecorated()->update($event);
}
$event->getEvents()->clear();
/** #var EntityWrittenEvent $writtenEvent */
foreach ($originalEvents as $writtenEvent) {
if ($writtenEvent->getEntityName() !== 'product') {
$event->getEvents()->add($writtenEvent);
continue;
}
$results = [];
foreach ($writtenEvent->getWriteResults() as $result) {
if (\in_array($result->getPrimaryKey(), self::FILTERED_IDS, true)) {
continue;
}
$results[] = $result;
}
$event->getEvents()->add(new EntityWrittenEvent('product', $results, $event->getContext()));
}
return $this->getDecorated()->update($event);
}
public function handle(EntityIndexingMessage $message): void
{
$data = array_diff($message->getData(), self::FILTERED_IDS);
$newMessage = new ProductIndexingMessage($data, $message->getOffset(), $message->getContext(), $message->forceQueue());
$this->getDecorated()->handle($newMessage);
}
public function getTotal(): int
{
return $this->getDecorated()->getTotal();
}
public function getOptions(): array
{
return $this->getDecorated()->getOptions();
}
}
How can I pass the decoded Data from my Api to my GetX Controller?
Here is my Class "Germany" and my fetchGermany() Function.
Future<Germany> fetchGermany() async {
final response =
await get(Uri.parse('https://api.corona-zahlen.org/germany'));
if (response.statusCode == 200) {
return Germany.fromJson(jsonDecode(response.body));
} else {
throw Exception('Failed to get data');
}
}
class Germany {
int cases;
int deaths;
int recovered;
double weekIncidence;
double casesPer100k;
int casesPerWeek;
Germany(
{required this.cases,
required this.deaths,
required this.recovered,
required this.weekIncidence,
required this.casesPer100k,
required this.casesPerWeek});
factory Germany.fromJson(Map<String, dynamic> json) {
return Germany(
cases: json["cases"],
deaths: json["deaths"],
recovered: json["recovered"],
weekIncidence: json["weekIncidence"],
casesPer100k: json["casesPer100k"],
casesPerWeek: json["casesPerWeek"]);
}
}
Here is my GetX controller which is empty at the moment:
class DetailController extends GetxController {
}
So basically I just want to be able to acceess this data:
cases: json["cases"],
deaths: json["deaths"],
recovered: json["recovered"],
weekIncidence: json["weekIncidence"],
casesPer100k: json["casesPer100k"],
casesPerWeek: json["casesPerWeek"]
While I agree with #DarShan that you don't necessarily need a GetXController here, I still would just for the simple sake of using a stateless widget over a stateful widget. If for no other reason than less cluttered UI code and separating business logic.
Also not sure if your Api call function is global or if that's just how you have it in your example, but if it is global I'd create a helper class.
class ApiHelper {
Future<Germany> fetchGermany() async {
final response =
await get(Uri.parse('https://api.corona-zahlen.org/germany'));
if (response.statusCode == 200) {
return Germany.fromJson(jsonDecode(response.body));
} else {
throw Exception('Failed to get data');
}
}
}
Then your GetX class can look like this.
class DetailController extends GetxController {
Germany germany;
#override
void onInit() async {
super.onInit();
final apiHelper = ApiHelper();
germany = await apiHelper.fetchGermany();
}
}
And here's an example using GetView widget which is just a stateless widget with a built in controller of the type you provided without having to find it.
class GermanyExample extends GetView<DetailController> {
#override
Widget build(BuildContext context) {
// access the initialized Germany object with controller.germany
return // the rest of your UI
}
}
Why not directly use the returned Germany object?
I don't see a need to use GetxController here.
Can be simply used as:
Germany _germany;
#override
void initState() {
super.initState();
fetchGermanyData();
}
fetchGermanyData() async {
final fetchedData = await fetchGermany();
setState(() => _germany = fetchedData);
}
/// use ? : operator to show relevant UI in the build method.
I just started with learning how to test within Laravel. I came across some problems though..
I'm testing my controller and want to check if a View has a variable assigned.
My controller code:
class PagesController extends \BaseController {
protected $post;
public function __construct(Post $post) {
$this->post = $post;
}
public function index() {
$posts = $this->post->all();
return View::make('hello', ['posts' => $posts]);
}
}
And my view contains a foreach loop to display all posts:
#foreach ($posts as $post)
{{post->id}}
#endforeach
Last but not least my test file:
class PostControllerTest extends TestCase {
public function __construct()
{
// We have no interest in testing Eloquent
$this->mock = Mockery::mock('Eloquent', 'Post');
}
public function tearDown()
{
Mockery::close();
}
public function testIndex() {
$this->mock->shouldReceive('all')->once()->andReturn('foo');
$this->app->instance('Post', $this->mock);
$this->call('GET', '/');
$this->assertViewHas('posts');
}
}
Now comes the problem, when I run "phpunit" the following error appears:
ErrorException: Invalid argument supplied for foreach()
Any ideas why phpunit returns this error?
Your problem is here:
$this->mock->shouldReceive('all')->once()->andReturn('foo');
$this->post->all() (which is what you're mocking) should return an array, and that's what your view expects. You're returning a string.
$this->mock->shouldReceive('all')->once()->andReturn(array('foo'));
should take care of the error you have, though you'll then get an error of the "Getting property of non-object" type.
You could do this:
$mockPost = new stdClass();
$mockPost->id = 1;
$this->mock->shouldReceive('all')->once()->andReturn(array($mockpost));
You should mock the view as well:
public function testIndex() {
$this->mock->shouldReceive('all')->once()->andReturn('foo');
$this->app->instance('Post', $this->mock);
View::shouldReceive('make')->with('hello', array('posts', 'foo'))->once();
$this->call('GET', '/');
}
I was wondering if there's a method to detect if a scope is being used on an AR search in yii?
For example, a model might contain 2 scopes:
class MyModel extends CActiveRecord
{
...
function myScope1()
{
$this->getDbCriteria()->mergeWith(array(
'join'=>'etc...',
'condition'=>'foo = bar',
));
return $this;
}
function myScope2()
{
$this->getDbCriteria()->mergeWith(array(
'join'=>'etc...',
'condition'=>'foo2 = bar2',
));
return $this;
}
....
}
I'm calling the AR like so:
$results = MyModel::model()->myScope1()->myScope2()->findAll();
It's a very dynamic site and there are more than 2 scopes, some used, some not. there are a couple of scopes that shouldn't be applied if another scope is in use. To avoid hundreds of if else statements, can I do something like so:
class MyModel extends CActiveRecord
{
...
function myScope1()
{
$this->getDbCriteria()->mergeWith(array(
'condition'=>'foo = bar',
));
return $this;
}
function myScope2()
{
if($this->appliedScopes('myScope1')==false)
{
// scope myScope1 isn't applied, so apply this scope:
$this->getDbCriteria()->mergeWith(array(
'condition'=>'foo2 = bar2',
));
}
return $this;
}
....
}
Typical, think of a workaround almost right after posting!
In my case, applying 'OR' between the two scopes will work, so;
class MyModel extends CActiveRecord
{
...
function myScope1()
{
$this->getDbCriteria()->mergeWith(array(
'join'=>'etc...',
'condition'=>'foo = bar',
));
return $this;
}
function myScope2($useAnd=true)
{
$this->getDbCriteria()->mergeWith(array(
'join'=>'etc...',
'condition'=>'foo2 = bar2',
),$useAnd);
return $this;
}
....
}
Calling like so:
$results = MyModel::model()->myScope1()->myScope2(false)->findAll();
I am working on a project which includes a REST API component. I have a controller dedicated to handling all of the REST API calls.
Is there any way to catch all exceptions for that specific controller so that I can take a different action for those exceptions than the rest of the application's controllers?
IE: I'd like to respond with either an XML/JSON formatted API response that contains the exception message, rather than the default system view/stack trace (which isn't really useful in an API context). Would prefer not having to wrap every method call in the controller in its own try/catch.
Thanks for any advice in advance.
You can completely bypass Yii's default error displaying mechanism by registering onError and onException event listeners.
Example:
class ApiController extends CController
{
public function init()
{
parent::init();
Yii::app()->attachEventHandler('onError',array($this,'handleError'));
Yii::app()->attachEventHandler('onException',array($this,'handleError'));
}
public function handleError(CEvent $event)
{
if ($event instanceof CExceptionEvent)
{
// handle exception
// ...
}
elseif($event instanceof CErrorEvent)
{
// handle error
// ...
}
$event->handled = TRUE;
}
// ...
}
I wasn't able to attach events in controller, and I did it by redefinition CWebApplication class:
class WebApplication extends CWebApplication
{
protected function init()
{
parent::init();
Yii::app()->attachEventHandler('onError',array($this, 'handleApiError'));
Yii::app()->attachEventHandler('onException',array($this, 'handleApiError'));
}
/**
* Error handler
* #param CEvent $event
*/
public function handleApiError(CEvent $event)
{
$statusCode = 500;
if($event instanceof CExceptionEvent)
{
$statusCode = $event->exception->statusCode;
$body = array(
'code' => $event->exception->getCode(),
'message' => $event->exception->getMessage(),
'file' => YII_DEBUG ? $event->exception->getFile() : '*',
'line' => YII_DEBUG ? $event->exception->getLine() : '*'
);
}
else
{
$body = array(
'code' => $event->code,
'message' => $event->message,
'file' => YII_DEBUG ? $event->file : '*',
'line' => YII_DEBUG ? $event->line : '*'
);
}
$event->handled = true;
ApiHelper::instance()->sendResponse($statusCode, $body);
}
}
In index.php:
require_once(dirname(__FILE__) . '/protected/components/WebApplication.php');
Yii::createApplication('WebApplication', $config)->run();
You can write your own actionError() function per controller. There are several ways of doing that described here
I'm using the following Base controller for an API, it's not stateless API, mind you, but it can serve just aswell.
class BaseJSONController extends CController{
public $data = array();
public $layout;
public function filters()
{
return array('mainLoop');
}
/**
* it all starts here
* #param unknown_type $filterChain
*/
public function filterMainLoop($filterChain){
$this->data['Success'] = true;
$this->data['ReturnMessage'] = "";
$this->data['ReturnCode'] = 0;
try{
$filterChain->run();
}catch (Exception $e){
$this->data['Success'] = false;
$this->data['ReturnMessage'] = $e->getMessage();
$this->data['ReturnCode'] = $e->getCode();
}
echo json_encode($this->data);
}
}
You could also catch dbException and email those, as they're somewhat critical and can show underlying problem in the code/db design.
Add this to your controller:
Yii::app()->setComponents(array(
'errorHandler'=>array(
'errorAction'=>'error/error'
)
));
