I am posting some data to my table.
As my post data is pretty large, is there any way to check if all values are posted? Only then insert it in database.
Or perhaps try to insert it, let the database handle it?
Thank you in advance.
u can validate request with require attribute
example
class CreateNotebookRequest extends Request
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'modelName' => 'required',
....

Have this code:
this is in RentRequest model:
/**
* Apply all relevant advert filters.
*
* #param Builder $query
* #param ParameterFilter $filters
* #return Builder
*/
public function scopeParamFilter($query, ParameterFilter $filters)
{
$query->leftJoin('request_parameter', 'rent_requests.id', '=', 'request_parameter.request_id');
return $filters->apply($query);
}
this in parameter filter:
/**
* Filter the query by a given area.
*
* #param $total_area
* #return \Illuminate\Database\Eloquent\Builder
*/
protected function total_space($total_area)
{
$this->builder->where(function ($queryId) use ($total_area) {
$query = DB::table('request_parameter')->where('request_parameter.key', 'total_space_from');
if (!empty($total_area['from'])) {
$query->where('request_parameter.value', '>=', (int) $total_area['from']);
}
$valueIds = $query->pluck('request_id');
$haveNoValueIds = DB::table('request_parameter')
->selectRaw('DISTINCT request_id')
->whereNotIn('request_id',
DB::table('request_parameter')
->select('request_id')
->where('key', 'total_space')
)
->pluck('request_id');
$advertIds = $valueIds->merge($haveNoValueIds);
$queryId->whereIn('request_parameter.request_id', $advertIds->all());
});
return $this->builder;
}
this is request_parameter schema:
so i have simple has many relation with parameters table based on rent_request.id
now i make filter logic, and try to do the same logic as previous developers made, but i cant understand it
main question is how to filter requests by the parameters that lying in the another table ?
current filter function works with the same logic in another project, maybe there are errors there ?
sorry for my english <3
this is final version of my function, it works for me
/**
* Filter the query by a given area.
*
* #param $total_area
* #return \Illuminate\Database\Eloquent\Builder
*/
protected function total_space($total_area)
{
$this->builder->where(function ($queryId) use ($total_area) {
$query = DB::table('request_parameter');
if (!empty($total_area['from'])) {
$query->where('request_parameter.key', 'total_space_from')
->where('request_parameter.value', '<=', (int) $total_area['from']);
}
if (!empty($total_area['to'])) {
$query->where('request_parameter.key', 'total_space_to')
->where('request_parameter.value', '<=', (int) $total_area['to']);
}
$valueIds = $query->pluck('request_id');
info($valueIds);
$haveNoValueIds = DB::table('request_parameter')
->selectRaw('DISTINCT request_id')
->whereNotIn('request_id',
DB::table('request_parameter')
->select('request_id')
->where('key', 'total_space_from')
->orWhere('key', 'total_space_to')
)
->pluck('request_id');
$advertIds = $valueIds->merge($haveNoValueIds);
$queryId->whereIn('request_parameter.request_id', $advertIds->all());
});
return $this->builder;
}
p.s. the filter algo is next: even when adverts dont have these parameters, its also return from filter function.
these was the key to understand what they are do in this function, and helps me to solve my problem.
I would like to know how can I set up my auth middleware in laravel 5.4.I am trying to set up the redirect route in
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\Auth;
class RedirectIfAuthenticated
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #param string|null $guard
* #return mixed
*/
public function handle($request, Closure $next, $guard = null)
{
if (Auth::guard($guard)->check()) {
return redirect()->route('home');
}
return $next($request);
}
}
but there is no chages.
Can someone suggest a solution?
Your middleware probably works as is but you will still need to enable this. Information regarding registering middleware can be found here but in short:
// Within App\Http\Kernel Class...
protected $routeMiddleware = [
'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
];
This will name your middleware "guest" (which might already be enabled if you executed php artisan make:auth beforehand.
Then you will need to apply it this can be done in 1 of 2 ways.
On the route.
Directly
Route::get('admin/profile', 'AdminController#show')->middleware('guest');
With groups
Route::group(['middleware' => ['guest']], function () {//other routes});
I'm building a Rest API and I receive a json_encoded string from the clients.
I want this string to be decoded before saving my entity, because it's going into a jsonb field in PostgreSQL.
The behavior I want is :
Validate that the string is valid json, if not, add a violation in the form via a custom validator
Automatically decode the string and set the json object in the entity property
I've tried two different strategies
In the entity setMetadata($value) method, if $value is a string, I decode it
I created a DataTransformer that json_decode the value received in the form
But both these solutions don't work because the custom validator I created is called after, and it calls directly $lesson->getMetadata(). Since the value has already been decoded (either in the setMetadata() method or in the DataTransformer, the validator receive either a json object or null. So I can't add a violation to the form, since I have no way to know if the value received was actually null, or if the string was malformed.
Here is the lesson entity:
class Lesson extends BaseContent
{
[…]
/**
* #var jsonb
*
* #ORM\Column(name="metadata", type="jsonb", nullable=true)
* #KreactiveAssert\Json
*/
private $metadata;
[…]
}
Here is the custom validator:
class JsonValidator extends ConstraintValidator
{
public function validate($value, Constraint $constraint)
{
if ($value && !json_decode($value)) {
$this->context->addViolation($constraint->message, array('%string%' => $value));
}
}
}
And here is the DataTransformer:
class StringToJsonTransformer implements DataTransformerInterface
{
/**
* Transform a json object to a string
* #param Json|null $json
* #return String
*/
public function transform($json)
{
if (null === $json) {
return "";
}
return json_encode($json);
}
/**
* Transform a string to a json object
* #param String $string
* #return Object
*/
public function reverseTransform($string)
{
if (!$string) {
return null;
}
throw new TransformationFailedException('error transforming');
return json_decode($string);
}
}
Is there any way I can validate the input data in the form, and then set the metadata as a json object?
I've found this (I don't know how come I didn't find it earlier):
Combine constraints and data transformers
I'm going to make an ugly workaround as suggested, even though I don't like that solution.
<?php
class StringToJsonTransformer implements DataTransformerInterface
{
/**
* Transform a string to a json object
* #param String $string
* #return Object
*/
public function reverseTransform($string)
{
if (!$string) {
return null;
}
/*
* UGLY WORKAROUND
* we return -1 if the json_decode fail
* so the validator can add a violation in the form telling
* the json string was not valid
* If we don't do this, the validator will receive either
* null or a json object. In case of null, there is no way to
* tell if the client sent null, or if the decoding failed
*/
$value = json_decode($string);
return $value ? $value : -1;
}
}
I'm still not sure if I'm going to return -1 or something else. In the custom validator, I get an error if I try to compare a jsonObject with -1 (which is normal).
I am planning to make a reverse geocoding based on the BazingaGeocoderBundle. A simple way to do that is write this simple code in the controller:
$result = $this->container
->get('bazinga_geocoder.geocoder')
->using('google_maps')
->reverse(48.79084170157100,2.42479377175290);
return $this->render("MinnAdsBundle:Motors:test.html.twig",
array('result'=>var_dump($result)));
Until here, things are going well.
My objective is to make the code nicer & resuable. So, I used this article to write my own GeocoderEventSubscriber as describer below:
<?php
namespace Minn\AdsBundle\Doctrine\Event;
use Doctrine\Common\EventSubscriber;
use Doctrine\ORM\Event\PreUpdateEventArgs;
use Doctrine\ORM\Event\LifecycleEventArgs;
//use Geocoder\Provider\ProviderInterface;
use Bazinga\Bundle\GeocoderBundle\Geocoder\LoggableGeocoder;
/**
* Subscribes to Doctrine prePersist and preUpdate to update an
* the address components of a MotorsAds entity
*
* #author majallouli
*/
class MotorsAdsGeocoderEventSubscriber implements EventSubscriber {
protected $geocoder;
public function __construct(LoggableGeocoder $geocoder){
$this->geocoder = $geocoder;
}
/**
* Specifies the list of events to listen
*
* #return array
*/
public function getSubscribedEvents(){
return array(
'prePersist',
'preUpdate',
);
}
/**
* Sets a new MotorsAds's address components if not present
*
* #param LifecycleEventArgs $eventArgs
*/
public function prePersist(LifecycleEventArgs $eventArgs){
$motorsAds = $eventArgs->getEntity();
if($motorsAds instanceof \Minn\AdsBundle\Entity\MotorsAds){
if( !$motorsAds->getCountry()){
$em = $eventArgs->getEntityManager();
$this->geocodeMotorsAds($motorsAds,$em);
}
}
}
/**
* Sets an updating MotorsAds's address components if not present
* or any part of address updated
*
* #param PreUpdateEventArgs $eventArgs
*/
public function preUpdate(PreUpdateEventArgs $eventArgs){
$motorsAds = $eventArgs->getEntity();
if($motorsAds instanceof \Minn\AdsBundle\Entity\MotorsAds){
if( !$motorsAds->getCountry() ){
$em = $eventArgs->getEntityManager();
$this->geocodeMotorsAds($motorsAds,$em);
$uow = $em->getUnitOfWork();
$meta = $em->getClassMetadata(get_class($motorsAds));
$uow->recomputeSingleEntityChangeSet($meta, $motorsAds);
}
}
}
/**
* Geocode and set the MotorsAds's address components
*
* #param type $motorsAds
*/
private function geocodeMotorsAds($motorsAds,$em){
$result = $this->geocode
->using('google_maps')
->reverse($motorsAds->getLat(),$motorsAds->getLng());
$motorsAds->setCountry(
$em->getRepository("MinnAdsBundle:Country")->findCountryCode($result['countryCode']));
}
}
After that, I declared my EventSubscriber as a service:
services:
# ...
geocoder_motorsads.listener:
class: Minn\AdsBundle\Doctrine\Event\MotorsAdsGeocoderEventSubscriber
arguments: [#bazinga_geocoder.geocoder] # almost sure that the error is here!!
tags:
- { name: doctrine.event_subscriber }
Actually, I get this error:
ContextErrorException: Notice: Undefined property: Minn\AdsBundle\Doctrine\Event\MotorsAdsGeocoderEventSubscriber::$geocode in /home/amine/NetBeansProjects/tuto/src/Minn/AdsBundle/Doctrine/Event/MotorsAdsGeocoderEventSubscriber.php line 78
I am almost sure that error is in the declaration of arguments of the EventSubscriber. Is it #bazinga_geocoder.geocoder?
Thank you for your help!
Your property is $this->geocoder but you're calling $this->geocode, you're spelling it wrong.
With the introduction of Zend_Rest_Route in Zend Framework 1.9 (and its update in 1.9.2) we now have a standardized RESTful solution for routing requests. As of August 2009 there are no examples of its usage, only the basic documentation found in the reference guide.
While it is perhaps far more simple than I assume, I was hoping those more competent than I might provide some examples illustrating the use of the Zend_Rest_Controller in a scenario where:
Some controllers (such as indexController.php) operate normally
Others operate as rest-based services (returning json)
It appears the JSON Action Helper now fully automates and optimizes the json response to a request, making its use along with Zend_Rest_Route an ideal combination.
Appears it was rather simple. I've put together a Restful Controller template using the Zend_Rest_Controller Abstract. Simply replace the no_results return values with a native php object containing the data you want returned. Comments welcome.
<?php
/**

{

}

*/
public function indexAction()
{
// do some processing...
// Send the JSON response:
$this->_helper->json($this->no_results);
}
// 1.9.2 fix
public function listAction() { return $this->_forward('index'); }
/**

public function getAction()
{
$id = $this->_getParam('id', 0);
// do some processing...
// Send the JSON response:
$this->_helper->json($this->no_results);

{

}
}
great post, but I would have thought the Zend_Rest_Controller would route the request to the right action with respect to the HTTP method used. It'd be neat if a POST request to http://<app URL>/Restful would automatically _forward to postAction for example.
I'll go ahead and provide another strategy below, but maybe I'm missing the point behind Zend_Rest_Controller ... please comment.
My strategy:
class RestfulController extends Zend_Rest_Controller
{
public function init()
{
$this->_helper->viewRenderer->setNoRender();
$this->_helper->layout->disableLayout();
}
public function indexAction()
{
if($this->getRequest()->getMethod() === 'POST')
{return $this->_forward('post');}
if($this->getRequest()->getMethod() === 'GET')
{return $this->_forward('get');}
if($this->getRequest()->getMethod() === 'PUT')
{return $this->_forward('put');}
if($this->getRequest()->getMethod() === 'DELETE')
{return $this->_forward('delete');}
$this->_helper->json($listMyCustomObjects);
}
// 1.9.2 fix
public function listAction() { return $this->_forward('index'); }
