Add a custom item to eloquent collection - laravel

I am using Laravel 7.
I have Category model. I sent categories as API with laravel resources. But now I want to add "all" value to categories.
Controller:
'categories' => CategoryResource::collection(Category::all()->push([
'id' => 0,
'name' => "All",
'subcategories' => []
]))
Resource:
public function toArray($request)
{
return [
'id' => $this->id,
'name' => $this->name,
'subcategories' => SubcategryResource::collection($this->subcategories)
];
}
Also, I wanted to add this custom value to the beginning of the collection.
But I am getting this error:
Trying to get property 'id' of non-object
Please, help me. How can I solve my problem?

Try replacing $this->id with $this['id']
If that works your query is returning an array not an object.

The problem here is that you're trying to add an item to the collection which is not a category model. $this in the resource reverts to the given model. However, you pass in an array so there is no model.
So try this instead
$allCategory = new Category(['id' => 0, 'name' => 'All']);
'categories' => CategoryResource::collection(Category::all()->prepend($allCategory));
I got these from: https://laracasts.com/discuss/channels/eloquent/add-a-custom-value-to-eloquent-collection

laravel endpoint hide field

How can i hide some fields ?
i want to hide the file field
Eloquent :
$reports = Report::select('id', 'file','company_id', 'title', 'year', 'created_at')
->orderBy('id', 'desc')
->paginate(10);
return ReportResource::collection($reports);
Model :
...
public function getFileSizeAttribute()
{
return Storage::disk('files')->size($this->attributes['file']);
}
....
ReportResource:
...
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'year' => $this->year,
'views' => $this->whenNotNull($this->views),
'file' => $this->whenNotNull($this->file), <-- i want to hide the file field
'file_size' => $this->fileSize, <-- but always show file_size
'created_at' => $this->created_at,
'company' => new CompanyResource($this->company),
];
}
to get file_size field i must select the file field , because it's depends on it to calculate the file size.
but i want to hide the file field before send the response.
i know i can use the protected $hidden = [] method in the model , but i don't want that, because file field it's required on others place. i just want to hide it on this endpoint only.
Since you are using API resources the best and clean way to do this is by using a Resource class for your collection.
Said that, you will have 3 Resources:
The first one, as it is, just for retrieving a single Model with file and file_size attributes. The one you already have ReportResource.php
...
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'year' => $this->year,
'views' => $this->whenNotNull($this->views),
'file' => $this->whenNotNull($this->file),
'file_size' => $this->fileSize,
'created_at' => $this->created_at,
'company' => new CompanyResource($this->company),
];
}
A new second resource to be used in your endpoint, without the file attribute. IE: ReportIndexResource.php
...
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'year' => $this->year,
'views' => $this->whenNotNull($this->views),
'file_size' => $this->fileSize,
'created_at' => $this->created_at,
'company' => new CompanyResource($this->company),
];
}
Now you need to create a Resource collection which explicitly defines the Model Resource to use. IE: ReportCollection.php
<?php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\ResourceCollection;
class ReportCollection extends ResourceCollection
{
/**
* The resource that this resource collects.
*
* #var string
*/
public $collects = ReportIndexResource::class;
}
Finally, use this new resource collection in your endpoint
$reports = Report::select('id', 'file','company_id', 'title', 'year', 'created_at')
->orderBy('id', 'desc')
->paginate(10);
return new ReportCollection($reports);
Of course, you can make use of makeHidden() method, but IMO is better to write a little more code and avoid a non desired attribute in your response because you forgot to make it hidden.
Also, in case you make use of makeHidden() method and you want to show the attribute in a future, you will have to update all your queries instead of a silgle resource file.
If you want to make it Hide From All Returns , you can Do this in model
protected $hidden = ['file'];
and if you want to do it temporirly with this query , you can Use MakeHidden method
$users = $reports->makeHidden(['file']);
It's clear in laravel docs , take a look
https://laravel.com/docs/9.x/eloquent-collections#method-makeHidden

Trying to get property of non-object in laravel shopping cart

I am using darryldecode for shopping cart in my project
this is my shoppingcartController and add method:
public function add(){
$pdt = Singleproduct::find(\request()->id);
\Cart::add(array(
array(
'id' => $pdt->id,
'name' => $pdt->name ,
'price' => $pdt->price,
'quantity' => \request()->qty ,
'attributes' => array()
)));
}
and this is route list:
Route::post('/cart/add' , 'admin\ShopingController#add')->name('cart.add');
and in my SingleProduct i have id,price and name!
the error is:"Trying to get property 'id' of non-object"
where is the problem??
The id may be returning null, or you may not be getting the right request object. Try injecting it into the method (which is kind of a 'Laravel') way to do it:
public function add(Illuminate\Http\Request $request){
$pdt = Singleproduct::find($request->input('id'));
}
Dump the request variable if you want to double check it has the id from your form: dd($request->all()); If id is not there in the dump, you can see where your problem lies.

Backpack Laravel Admin Incorrectly Redirects after Editing Model

I have a CrudController created for a model using the Backpack Laravel Admin Library.
When I update the model it redirects me incorrectly to a 404 page with the message No query results for model [App\Models\Group].
It is redirecting me to the incorrect URL from what I can tell.
admin/group/261/ instead of admin/group/261/edit
The model also does not update.
I have the "Save and Edit" option set on the green save button. If I try to change this I get the same error, but it doesn't update.
I'm able to save every other model correctly.
The update method in the CrudController is just the following. I've removed all the extra code.
public function update(){
$response = $this->traitUpdate();
return $response;
}
Figured this out. It was because I was referencing the Primary Key -> 'id' in the fields within the Group Crud Controller.
$this->crud->addField([
'name' => 'id',
'type' => 'text',
'attributes' => ['disabled' => 'disabled'],
]);
u can use id, u need delete attribute 'disabled' like this:
[
'name' => 'id',
'label' => 'ID',
'attributes' => [
'readonly' => 'readonly',
],
],

Laravel send mail with multiple check box value

i'm trying to make inquiry form where costumer fill up form then check the value on the checkbox then once they submit form will send email to me listing all the information the customer selected, now problem is i want to change this[event_id,requirement_id] instead of id replace it with name those two id parameter is from my two model listed below.
Model:
Event:[id,name]
Requirement:[id,name]
Controller:
public function store(Request $request)
{
$summary=[
'name' => $request->fullname,
'email' => $request->email,
'company' => $request->company,
'event' => $request->event_id,
'requirement' => $request->requirement_id
];
return $summary;
Mail::send('emails.contact-message',[
],function($mail) use($summary){
$mail->from('myemail#gmail.com', 'tester');
$mail->to('myemail#gmail.com')->subject('Contact Message');
});
return redirect()->back();
}
This is the result of my return request:
{"name":"myname","email":"myemail#gmail.com","company":"mycompany","event":["1","2"],"requirement":["1","2"]}
As you can see the array Event has value of 1 and 2 i wanted to replace it with its name output should be [Wedding,Birthday] i'm sorry for my bad english hope you understand me..
Well, you'd need to pull the name from your models.
The following should do the trick:
$events = App\Event::whereIn('id', $request->event_id)
->get()
->pluck('name')
->toArray();
$requirements = App\Requirement::whereIn('id', $request->requirement_id)
->get()
->pluck('name')
->toArray();
Obviously, replace name in the above example with the actual name field in your models. This is just an example.
$events and $requirements will both be an array containing the names matching the ids you are supplying in your request.
You also need to change your $summary array as follows:
$summary = [
'name' => $request->fullname,
'email' => $request->email,
'company' => $request->company,
'event' => $events
'requirement' => $requirements
];

How to properly hydrate and extract Doctrine Entities from Zend Forms

I'm just starting out with Doctrine and was rewriting some code to use Doctrine entities in some Forms.
I have an Entity Business which has some 1:n relations with addresses, employees, emails etc. the Setup is really basic and working fine.
To add new Businesses i created a BusinessForm and Fieldsets for each of my entities. Here the constructor of the form:
public function __construct($scenario='create', $entityManager = null) {
parent::__construct('business_form');
$this->scenario = $scenario;
$this->entityManager = $entityManager;
$this->setAttribute('method', 'post');
$businessFieldset = new BusinessFieldset($this->entityManager);
$businessFieldset->setUseAsBaseFieldset(true);
$this->add($businessFieldset);
$hydrator = new DoctrineHydrator($this->entityManager, new Business());
$this->setHydrator($hydrator);
$this->addElements();
$this->addInputFilter();
}
addElements just adds a Submit and CSRF input.
And here the Controller action:
public function addAction(){
$form = new BusinessForm('create', $this->entityManager);
if ($this->getRequest()->isPost()) {
$data = $this->params()->fromPost();
$form->setData($data);
if($form->isValid()) {
// save Object
return $this->redirect()->toRoute('subcontractor', ['action'=>'index']);
}
}
return new ViewModel([
'form' => $form
]);
}
The form validates and i can get the Data from the form with $form->getData(). But i cant figure out how to get a populated Object from the form using the form's hydrator. When I use setObject(new Business()) at the start of the controller i get an error while $form->isValid() is running :
Zend\Hydrator\ArraySerializable::extract expects the provided object to implement getArrayCopy()
Isnt that the wrong hydrator being called ?
If i dont setObject() but instead use $form->bind(new Business()) after the validation i get an empty Object from $form->getObject(). If i get the data and hydrate a new Object with the form's hydrator like so : $form->getHydrator()->hydrate($data['business], new Business()) i do get the populated Object i was expecting. (Business being the name of the base fieldset)
So my question is, how to i get the result of the last call from just using $form->getObject() after the validation?
[EDIT]
The Problem seems to be with the Collections of Fieldsets used as sub-fieldsets in the businessfieldset. If i validate the form without using the collections i do get the expected Business Object from $form->getData()
Here an example how i add the collection (in the business fieldset):
$this->add([
'name' => 'emails',
'type' => 'Zend\Form\Element\Collection',
'attributes' => [
'id' => 'business_emails',
],
'options' => [
'label' => 'Emails',
'count' => 1,
'should_create_template' => true,
'template_placeholder' => '__index__',
'allow_add' => true,
'target_element' => [
'type' => 'LwsSubcontractor\Form\EmailFieldset',
],
'target_class' => 'LwsSubcontractor\Entity\Email'
],
]);
and here the EmailFieldset:
public function __construct() {
parent::__construct('email');
$this->setObject(new Email());
$this->addElements();
}
protected function addElements() {
$this->add([
'name' => 'email',
'type' => 'Zend\Form\Element\Email',
'attributes' => [
'placeholder' => 'E-Mail (z.B. email#muster-email.de)',
'class' => 'form-control',
'required' => true,
'size' => 50,
],
'options' => [
'label' => 'Email',
],
]);
}
}
If using the Collections i get the Error message from above. So after adding a hydrator to each Fieldset i was fine.
Although i was under the impression that setting the hydrator for the form would result in the used fieldsets to inherit that hydrator.Or was this because of using the fieldsets as collections and not directly ?
You have to add the hydrator to all your fieldsets, personally I use DoctrineModule\Stdlib\Hydrator\DoctrineObject for doctrine entities.
I would also look at using the init() method to initialize your forms and add elements then register and retrieve your form and fieldsets through the FormElementManager, $serviceLocator->get('FormElementManager')->get(yourFieldsetorForm::class). The form can than be injected into your controller.
I hope this helps.
