Laravel Importing to Excel , error when passing a variable - laravel

I want to import some categories, but what i need is also the parent category id.
public function importCategory(Request $request, $cat_id){
$import = new CategoryImport($cat_id);
$import->import($request->file);
if ($import->failures()->count() > 0) {
$message = '';
foreach ($import->failures() as $failure) {
$failure->row(); // row that went wrong
$failure->attribute(); // either heading key (if using heading row concern) or column index
$failure->errors(); // Actual error messages from Laravel validator
$failure->values(); // The values of the row that has failed.
}
return redirect()->back();
} else {
return redirect()->back()->with('success', sprintf('Success'));
}
}
Here is the CategoryImport.php
class CategoryImport implements WithHeadingRow, WithValidation, SkipsOnFailure,OnEachRow
{
use Importable, SkipsFailures;
/**
* #param array $row
*
* #return \Illuminate\Database\Eloquent\Model|null
*/
protected $cat_id = null;
public function __construct( $cat_id) {
$category_id = $cat_id;
}
public function onRow(Row $row)
{
$row=$row->toArray();
Category::create([
'name' => $row['name'],
'image' => $row['image'],
'business_category_id' => $this->category_id,
]);
}
}
So here is the error, it says undefined property, and i am trying to figure it out but don't understand.
Undefined property: App\Imports\CategoryImport::$category_id

Inside the constructor you need to assign the correct variable.
class CategoryImport implements WithHeadingRow, WithValidation, SkipsOnFailure,OnEachRow
{
use Importable, SkipsFailures;
/**
* #param array $row
*
* #return \Illuminate\Database\Eloquent\Model|null
*/
protected $cat_id = null;
public function __construct($cat_id) {
$this->cat_id = $cat_id;
}
I think the line 'business_category_id' => $this->category_id is wrong. You need to use
'business_category_id' => $this->cat_id
because that is the variable you assign in the constructor.

You didn't set cat_id properly. In your CategoryImport you should have :
protected $category_id = null;
public function __construct($cat_id) {
$$this->category_id = $cat_id;
}

Extra data on a collection operation

Does anybody know how to add extra data on a collection?
The doc says much about how to add extra data on an item which translates into decorating the ItemNormalizer service, and it works pretty well.
But I’m struggling in finding out which normalizer to decorate when it comes to add some data on a collection of entities. The extra data could be anything: the current user logged in, a detailed pager, some debug parameters, ... that are not related to a specific entity, but rather on the request itself.
The only working solution for now is to hook on a Kernel event but that's definitely not the code I like to write:
use ApiPlatform\Core\EventListener\EventPriorities;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpKernel\Event\GetResponseForControllerResultEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\Security\Core\Security;
use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
final class SerializeListener implements EventSubscriberInterface
{
/**
* #var Security
*/
private $security;
/**
* #var NormalizerInterface
*/
private $normalizer;
public function __construct(
Security $security,
NormalizerInterface $normalizer
) {
$this->security = $security;
$this->normalizer = $normalizer;
}
public function addCurrentUser(GetResponseForControllerResultEvent $event)
{
$request = $event->getRequest();
if ($request->attributes->has('_api_respond')) {
$serialized = $event->getControllerResult();
$data = json_decode($serialized, true);
$data['hydra:user'] = $this->normalizer->normalize(
$this->security->getUser(),
$request->attributes->get('_format'),
$request->attributes->get('_api_normalization_context')
);
$event->setControllerResult(json_encode($data));
}
}
/**
* #inheritDoc
*/
public static function getSubscribedEvents()
{
return [
KernelEvents::VIEW => [
'addCurrentUser',
EventPriorities::POST_SERIALIZE,
],
];
}
}
Any ideas?
Thank you,
Ben
Alright, I finally managed to do this.
namespace App\Api;
use Symfony\Component\Serializer\Normalizer\NormalizerAwareInterface;
use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
final class ApiCollectionNormalizer implements NormalizerInterface, NormalizerAwareInterface
{
/**
* #var NormalizerInterface|NormalizerAwareInterface
*/
private $decorated;
public function __construct(NormalizerInterface $decorated)
{
if (!$decorated instanceof NormalizerAwareInterface) {
throw new \InvalidArgumentException(
sprintf('The decorated normalizer must implement the %s.', NormalizerAwareInterface::class)
);
}
$this->decorated = $decorated;
}
/**
* #inheritdoc
*/
public function normalize($object, $format = null, array $context = [])
{
$data = $this->decorated->normalize($object, $format, $context);
if ('collection' === $context['operation_type'] && 'get' === $context['collection_operation_name']) {
$data['hydra:meta'] = ['foo' => 'bar'];
}
return $data;
}
/**
* #inheritdoc
*/
public function supportsNormalization($data, $format = null)
{
return $this->decorated->supportsNormalization($data, $format);
}
/**
* #inheritdoc
*/
public function setNormalizer(NormalizerInterface $normalizer)
{
$this->decorated->setNormalizer($normalizer);
}
}
# config/services.yaml
services:
App\Api\ApiCollectionNormalizer:
decorates: 'api_platform.hydra.normalizer.collection'
arguments: [ '#App\Api\ApiCollectionNormalizer.inner' ]
Keep it for the records :)

How to use 2 attributes in Validation Rule Class Laravel

How can I use two attributes in the Validation Rule of Laravel. This is my function where I have 2 variables groupid and grouppassword. Currently only groupid is taken.
public function groupPasswordValidationReal(Request $request){
$groupid = $request->input('groupid');
$grouppassword = $request->input('grouppassword');
$validator = \Validator::make($request->all(), [
'groupid' => [new ValidRequest] //How to pass grouppassword in this function???
]);
return redirect('home')->with('success', 'Request is send!');
}
How can I pass both to my Validation Class? Here you can see the functions in the Validation Class.
namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
use App\Group;
class ValidTest implements Rule
{
public function passes($attribute, $value)
{
//$value is groupid
$validPassword = Group::where([['idgroups', $value],['group_password', /*Here I need grouppassword*/]])->first();
if($validPassword){
return true;
}else{
return false;
}
}
public function message()
{
return 'Wrong Password!';
}
}
Add property and constructor to your ValidTest class. Pass the required value as an argument to the new object.
ValidTest.php
namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
use App\Group;
class ValidTest implements Rule
{
/**
* The group password.
*
* #var string
*/
public $groupPassword;
/**
* Create a new rule instance.
*
* #param \App\Source $source
* #param string $branch
* #return void
*/
public function __construct($groupPassword)
{
$this->groupPassword = $groupPassword;
}
public function passes($attribute, $value)
{
//$value is groupid
//$this->groupPassword is group_password
$validPassword = Group::where([['idgroups', $value],['group_password', $this->groupPassword]])->first();
if($validPassword){
return true;
}else{
return false;
}
}
public function message()
{
return 'Wrong Password!';
}
}
Controller
public function groupPasswordValidationReal(Request $request){
$groupid = $request->input('groupid');
$grouppassword = $request->input('grouppassword');
$validator = \Validator::make($request->all(), [
'groupid' => new ValidTest($grouppassword)
]);
return redirect('home')->with('success', 'Request is send!');
}
Source : custom-validation-rules-in-laravel-5-5
Note : This is not a tested solution.
Use the Rule constructor like
class ValidUser implements Rule
{
private $grouppassword;
/**
* Create a new rule instance.
*
* #return void
*/
public function __construct($grouppassword)
{
$this->grouppassword = $grouppassword;
}
/**
* Determine if the validation rule passes.
*
* #param string $attribute
* #param mixed $value
* #return bool
*/
public function passes($attribute, $value)
{
// $this->grouppassword
// $groupid = $value
// Do your logic...
return true;
}
/**
* Get the validation error message.
*
* #return string
*/
public function message()
{
return 'The :attribute must something...';
}
}
Usage
Route::post('/user', function (Request $request) {
// Parameter validation
$validator = Validator::make($request->all(), [
'groupid' => 'required',
'grouppassword' => ['required', new ValidUser($request->groupid), ]
]);
if ($validator->fails())
return response()->json(['error' => $validator->errors()], 422);
});
I think you could use a closure there. So something like this:
$validator = \Validator::make($request->all(), function() use ($groupid, $grouppassword) {
$validPassword = Group::where([['idgroups', $value],['group_password', $grouppassword]])->first();
if($validPassword){
return true;
}else{
return false;
}
}
I haven't run it though.
If you are calling the validation from a Request class, you can access the extra value as e.g.
request()->validate([
'groupid' => [new ValidTest(request()->input('grouppassword'))]
]);

Laravel 5 FormRequest validator with multiple scenarios

I would like to ask how should I handle validation on multiple scenarios using FormRequest in L5? I know and I was told that I can create saparate FormRequest files to handle different validations but it is very redundant and also noted that I would need to inject it into the controller manually using the use FormRequest; keyword. What did previously in L4.2 is that I can define a new function inside my customValidator.php which then being called during controller validation via trycatch and then the data is being validated by service using the below implementation.
class somethingFormValidator extends \Core\Validators\LaravelValidator
{
protected $rules = array(
'title' => 'required',
'fullname' => 'required',
// and many more
);
public function scenario($scene)
{
switch ($scene) {
case 'update':
$this->rules = array(
'title' => 'required',
'fullname' => 'required',
// and other update validated inputs
break;
}
return $this;
}
}
Which then in my LaravelValidator.php
<?php namespace Core\Validators;
use Validator;
abstract class LaravelValidator {
/**
* Validator
*
* #var \Illuminate\Validation\Factory
*/
protected $validator;
/**
* Validation data key => value array
*
* #var Array
*/
protected $data = array();
/**
* Validation errors
*
* #var Array
*/
protected $errors = array();
/**
* Validation rules
*
* #var Array
*/
protected $rules = array();
/**
* Custom validation messages
*
* #var Array
*/
protected $messages = array();
public function __construct(Validator $validator)
{
$this->validator = $validator;
}
/**
* Set data to validate
*
* #return \Services\Validations\AbstractLaravelValidator
*/
public function with(array $data)
{
$this->data = $data;
return $this;
}
/**
* Validation passes or fails
*
* #return Boolean
*/
public function passes()
{
$validator = Validator::make(
$this->data,
$this->rules,
$this->messages
);
if ($validator->fails())
{
$this->errors = $validator->messages();
return false;
}
return true;
}
/**
* Return errors, if any
*
* #return array
*/
public function errors()
{
return $this->errors;
}
}
and then finally this is how i call the scenarios inside services like this
public function __construct(somethingFormValidator $v)
{
$this->v = $v;
}
public function updateSomething($array)
{
if($this->v->scenario('update')->with($array)->passes())
{
//do something
else
{
throw new ValidationFailedException(
'Validation Fail',
null,
$this->v->errors()
);
}
}
So the problem is now since i have migrated to L5 and L5 uses FormRequest, how should I use scenario validation in my codes?
<?php namespace App\Http\Requests;
use App\Http\Requests\Request;
class ResetpasswordRequest extends Request {
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'login_email' => 'required',
'g-recaptcha-response' => 'required|captcha',
];
}
public function messages()
{
return [
'login_email.required' => 'Email cannot be blank',
'g-recaptcha-response.required' => 'Are you a robot?',
'g-recaptcha-response.captcha' => 'Captcha session timeout'
];
}
public function scenario($scene)
{
switch ($scene) {
case 'scene1':
$this->rules = array(
//scenario rules
);
break;
}
return $this;
}
}
also how should I call it in the controller?
public function postReset(ResetpasswordRequest $request)
{
$profile = ProfileService::getProfileByEmail(Request::input('login_email'));
if($profile == null)
{
$e = array('login_email' => 'This email address is not registered');
return redirect()->route('reset')->withInput()->withErrors($e);
}
else
{
//$hash = ProfileService::createResetHash($profile->profile_id);
$time = strtotime('now');
$ip = Determinator::getClientIP();
MailProcessor::sendResetEmail(array('email' => $profile->email,
'ip' => $ip, 'time' => $time,));
}
}
I believe the real issue at hand is everything is validated through the form request object before it reaches your controller and you were unable to set the appropriate validation rules.
The best solution I can come up with for that is to set the validation rules in the form request object's constructor. Unfortunately, I am not sure how or where you are able to come up with the $scene var as it seems to be hard-coded in your example as 'update'.
I did come up with this though. Hopefully reading my comments in the constructor will help further.
namespace App\Http\Requests;
use App\Http\Requests\Request;
class TestFormRequest extends Request
{
protected $rules = [
'title' => 'required',
'fullname' => 'required',
// and many more
];
public function __construct()
{
call_user_func_array(array($this, 'parent::__construct'), func_get_args());
// Not sure how to come up with the scenario. It would be easiest to add/set a hidden form field
// and set it to 'scene1' etc...
$this->scenario($this->get('scenario'));
// Could also inspect the route to set the correct scenario if that would be helpful?
// $this->route()->getUri();
}
/**
* 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 $this->rules;
}
public function scenario($scene)
{
switch ($scene) {
case 'scene1':
$this->rules = [
//scenario rules
];
break;
}
}
}
You can use laratalks/validator package for validation with multiple scenarios in laravel. see this repo

Yii - validate custom field

I use model which not contain attribute 'countries' because I'm saving it in relations-model via many-to-many relation. When I'm creating form in view I use multiple select for custom field 'countries'. How can I validate it from model on $model->validate()?
// protected/extensions/validators/CountryValidator.php
class CountryValidator extends CValidator
{
/**
* #inheritdoc
*/
protected function validateAttribute($object, $attribute)
{
/* #var $object CFormModel */
// for example check exist countryId in db or no
// you can use any other logic
$country = Country::model()->findByPk($object->$attribute);
if (null != $country) {
$object->addError($attribute, 'country not found');
}
}
...
// in your model
public function rules()
{
return array(
array('countryId', 'ext.validators.CountryValidator'),
...
// in config
'import' => array(
'ext.validators.*',
...
How to use:
$yourModel = new YourModel();
$yourModel->countryId = -1;
$yourModel->validate();
print_r($yourModel->getErrors()); die();

I am just trying to insert a new row with three Columns (I call the insertNew function on instance of Student)
1- ID automatically incremented
2- Special Code
3- Name
And I got this above Msg
What's I have tried till now :
removing all relations between from this model and other models
that has this one in the relation
Removed the validation step in insertNew()
Removed the all Input class calls and used literal data instead.
note that I use similar Inserting function on other Models and it works flawlessly
Any Comments , Replies are appreciated :D
Solution
I solved it and the problem was that I am accessing the validator
$this->validator = \Validator::make(\Input::all(), $this->newValidationRules);
And it was because I forgot that
/**
* The validator object.
*
* #var Illuminate\Validation\Validator
*/
protected $validator;
I had a similar problem. But to me, changing this code:
if ($this->validator->passes()) {
$this->name = \Input::get('studentName');
$this->code = \Input::get('studentCode');"
to this:
if ($this->validator->passes()) {
$this->setAttribute ("name" , \Input::get('studentName'));
$this->setAttribute ("code" , \Input::get('studentCode'));"
solved it.
