In yii2 set-up I have multiple models - one being one to many with repeat fields in form where I can edit fieldset or add new records.
but I am facing issue of duplicate key error.
To overcome the same I am trying this code:
try{
$userchild->save();
}
catch(\Exception $e){
$userchild->isNewRecord = false;
$usrchild->save();
}
but I am getting the exception:
Unknown Method – yii\base\UnknownMethodException
Calling unknown method: app\controllers\UserController::setIsNewRecord()
What I am missing here?
update with more code:
if ($model->load(Yii::$app->request->post()) && $profile->load(Yii::$app->request->post()) && $billinginfo->load(Yii::$app->request->post()) ) {
$model->username = $model->email;
$model->save();
$profile->save();
$billinginfo->save();
if (!empty($_POST['UserChildren']) && !is_null($_POST['UserChildren'])) {
foreach($_POST['UserChildren'] as $rows){
$userchild = New UserChildren;
$userchild->user_id = $model->id;
$userchild->id =$rows['id'];
$userchild->attributes=$rows;
try{
$userchild->save();
} catch(\Exception $e){
$userchild->setIsNewRecord(false);
$usrchild->save();
}
}
}
Now I am getting the error:
Unknown Property – yii\base\UnknownPropertyException
Getting unknown property: app\models\UserChildren::_attributes
if you want assigng the attributes you should use
$userchild->setAttributes($rows, TRUE);

I always use Laravel project since Laravel 4 up to 7. But this is my first time encountering and error when I migrate my database in freshly download Laravel. This is the error when I migrate:

Before this happen I start IIS from the IIS Manager. I don't know if this will effect. I turn it on because I run a C# web application on my end.
It looks like this is composer problem. Just try to run this bash script:
composer dump-autoload
Is there a way to make laravel report a malformed JSON on input? Now the controller just doesnt receive any data and I would want it to raise an exception if content type is json on request
Do it in a before filter:
App::before(function ($request)
{
if ( ! str_contains($request->getContentType(), 'json')) return;
json_decode($request->getContent());
if (json_last_error() != JSON_ERROR_NONE)
{
throw new Exception('Malformed JSON.');
}
});
If you don't want it to fail when there's no content, use this:
App::before(function ($request)
{
if ( ! ($content = $request->getContent())) return;
if ( ! str_contains($request->getContentType(), 'json')) return;
json_decode($content);
if (json_last_error() != JSON_ERROR_NONE)
{
throw new Exception('Malformed JSON.');
}
});
I'm extracting two different sets of data from a function in my model (syntax below). I'm trying to display the data my view. I put the variable in var_dump and var_dump is displaying the requested information but I'm having a hard time accessing that information. I'm getting two different sets of error messages as well. They are below. How would I display the information in my view? Thanks everyone.

In your controller you are assigning the result of function getJoinInformation to the variable allvehicledata. This variable is then assigned to the view.
The function getJoinInformation is returning an array with the following
$data = array(
'getPrice' => $this->getPrice($year,$make,$model),
'getOtherPrice' => $this->getOtherPrice($year,$make,$model)
);
So in your view you can access the attributes getPrice and getOtherPrice in the object $allvehicledata like
$allvehicledata->getPrice;
$allvehicledata->getOtherPrice;
In line 7 you try to access the attribute cardescription_id, which is not an attribute of the object $allvehicledata.
I think this is an attribute which is get from the db query, so you should try to access it allvehicledata->getPrice->cardescription_id or allvehicledata->getOtherPrice->cardescription_id.
In line 9 you try to access some data stored in an array $model = $allvehicledata[0]->model;, but $allvehicledata is not an array.
It it possible in Silex to use an error handler based on what exception is thrown?
I know this is possible with a single exception handler and a switch statement on the classname of the thrown exception but to me it seems the "Silex way" is cleaner, yet doesn't work.
This is how I would expect it to work
<?php
// Handle access denied errors
$app->error(function (\App\Rest\Exception\AccessDenied $e) {
$message = $e->getMessage() ?: 'Access denied!';
return new Response($message, 403);
});
// Handle Resource not found errors
$app->error(function (\App\Rest\Exception\ResourceNotFound $e) {
$message = $e->getMessage() ?: 'Resource not found!';
return new Response($message, 404);
});
// Handle other exception as 500 errors
$app->error(function (\Exception $e, $code) {
return new Response($e->getMessage(), $code);
});
Problem is that when I throw a ResourceNotFound exception in my controller, the errorhandler tied to AccessDenied is executed
Catchable fatal error: Argument 1 passed to {closure}() must be an instance of App\Rest\Exception\AccessDenied, instance of App\Rest\Exception\ResourceNotFound given
Is this achievable in another way or should I just stuff everything in the handler that works with generic Exceptions and switch on the type of exception thrown?
PS: i'm aware of the $app->abort() method but prefer working with exceptions
EDIT: This feature has now made it into Silex core!
This is currently not possible. Right now you'd have to either have a single handler with a switch statement, or many handlers with an if ($e instanceof MyException) each.
I do like the idea though, and it should be possible to implement it by using reflection. It would be awesome if you could create a new ticket on the tracker, or even work on a patch, if you're interested.
Cheers!
Another solution that I use in my projects:
class ProcessCallbackException extends Exception
{
public function __construct(\Closure $callback, $message = "", Exception $previous = null)
{
parent::__construct($message, 0, $previous);
$this->callback = $callback;
}
public $callback;
}
class AccessDeniedException extends ProcessCallbackException
{
public function __construct($message = null)
{
$f = function() {
return app()->redirect('/login');
};
parent::__construct($f, $message);
}
}
# Handle your special errors
$app->error(function (\Exception $e, $code) {
if ($e instanceof ProcessCallbackException)
{
/** #var ProcessCallbackException $callbackException */
$callbackException = $e;
return call_user_func($callbackException->callback);
}
else
return null;
});
I have setup a project with both Elmah and EF4.1 Code First.
The project is throwing a System.Data.Entity.Validation.DbEntityValidationException, but Elmah is not providing enough detail to determine what validation is failing. All that is logged is:
System.Data.Entity.Validation.DbEntityValidationException: Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.
Is there a way to make Elmah expand and log the EntityValidationErrors property?
List<IUserFeedback> errors = new List<IUserFeedback>();
try
{
_dbContext.SaveChanges();
Updated(this, HasUnsavedChanges);
}
catch (DbEntityValidationException ex)
{
foreach (var x in ex.EntityValidationErrors)
{
foreach (var y in x.ValidationErrors)
{
if (!String.IsNullOrWhiteSpace(y.PropertyName))
errors.Add(new UserFeedback() {
FeedbackFlags = TypeOfUserFeedbackFlags.Error,
Message = String.Format("Unable to save {0} due to an issue with its \"{1}\" value. The error returned was \"{2}\"",x.Entry.Entity, y.PropertyName, y.ErrorMessage)
});
else
errors.Add(new UserFeedback() {
FeedbackFlags = TypeOfUserFeedbackFlags.Error,
Message = String.Format("Unable to save {0} due to the error \"{1}\"", x.Entry, y.ErrorMessage)
});
}
}
}
return errors;
