easyadmin crud controllers: adding value into related entity - php

Question

I have question concerning easyadmin3. In my admin panel I have a productCrudController and one of the values I want to be able to set when creating a new product is the price.
For the price I have a separate table though which contains all my prices with a date. The idea being that the price of a product van change over time and my client wants to be able to have an overview of the price history for each product.
So in my productCrudController I work with an associationField to link to my prices entity. However I'm really stuck with the following practical issue: I don't want to have to add a price in a priceCrudController which I would then be able to select in my productCrudController (the way the associationField expects me to do).
What I want is that I can create a product and input a price which would then be inserted into my prices table.
My code:
productCrudController ->
Right now I have a field for prices where I can select a price in a dropdown menu, but so I have to add the price first with a priceCrudController, which really isn't practical.
class ProductsCrudController extends AbstractCrudController
{
public static function getEntityFqcn(): string
{
return Products::class;
}
public function configureFields(string $pageName): iterable
{
$image = ImageField::new('image')->setBasePath('resources/images');
$imageFile = TextField::new('imageFile')->setFormType(VichImageType::class);
$fields = [
IdField::new('id', 'ID')->hideOnForm(),
TextField::new('name'),
TextEditorField::new('description'),
AssociationField::new('category'),
AssociationField::new('plants')->setTemplatePath('list.html.twig'),
NumberField::new('stock'),
AssociationField::new('prices', 'bruto price')->onlyOnIndex()->setTemplatePath('price.html.twig'),
];
if($pageName == Crud::PAGE_INDEX || $pageName == Crud::PAGE_DETAIL){
$fields[] = $image;
} else {
$fields[] = $imageFile;
}
return $fields;
}
I tried just making a numberField for 'prices' to see if I could just enter a value that would then be persisted in the database, but I get the following error:
Object of class Doctrine\ORM\PersistentCollection could not be
converted to string
This is my 'prices' property in my 'products' entity and the methods:
/**
* #ORM\OneToMany(targetEntity=Prices::class, mappedBy="product")
* #Groups({"products:read"})
*/
private $prices;
/**
* #return Collection|Prices[]
*/
public function getPrices(): Collection
{
return $this->prices;
}
public function addPrice(Prices $price): self
{
if (!$this->prices->contains($price)) {
$this->prices[] = $price;
$price->setProduct($this);
}
return $this;
}
public function removePrice(Prices $price): self
{
if ($this->prices->removeElement($price)) {
// set the owning side to null (unless already changed)
if ($price->getProduct() === $this) {
$price->setProduct(null);
}
}
return $this;
}
I have the feeling I might need to do something with event listeners, but I don't really know how to go about it as I haven't really worked with them before.
I'd be very grateful for any help

You can create a form for the Prices entity and then use it in your product
CollectionField::new('prices')
->hideOnIndex()
->setLabel('bruto price')
->setTemplatePath('price.html.twig')
->setFormTypeOptions([
'label' => false,
'delete_empty' => true,
'by_reference' => false,
])
->setEntryIsComplex(false)
->setCustomOptions([
'allowAdd' => true,
'allowDelete' => false,
'entryType' => PricesType::class, // Your price form class here
'showEntryLabel' => false,
])
;
