easyadmin crud 控制器:为相关实体增加价值 [英] easyadmin crud controllers: adding value into related entity
问题描述
我有关于 easyadmin3 的问题.在我的管理面板中，我有一个 productCrudController，我希望在创建新产品时能够设置的值之一是价格.对于价格，我有一个单独的表格，其中包含我所有的价格和日期.我的想法是货车的价格会随着时间的推移而变化，我的客户希望能够大致了解每种产品的价格历史.
因此，在我的 productCrudController 中，我使用了一个关联字段来链接到我的价格实体.但是，我确实遇到了以下实际问题:我不想在 priceCrudController 中添加价格，然后我就可以在我的 productCrudController 中进行选择(associationField 希望我这样做).
我想要的是我可以创建一个产品并输入一个价格，然后将其插入到我的价格表中.
我的代码:
productCrudController ->
现在我有一个价格字段，我可以在下拉菜单中选择价格，但我必须先使用 priceCrudController 添加价格，这确实不实用.
class ProductsCrudController 扩展 AbstractCrudController{公共静态函数 getEntityFqcn(): 字符串{返回产品::类；}公共函数 configureFields(string $pageName): 可迭代{$image = ImageField::new('image')->setBasePath('resources/images');$imageFile = TextField::new('imageFile')->setFormType(VichImageType::class);$字段 = [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[] = $image;} 别的 {$fields[] = $imageFile;}返回 $fields;}我尝试只为价格"创建一个 numberField 以查看是否可以输入一个值然后将其保留在数据库中，但出现以下错误:
<块引用>Doctrine\ORM\PersistentCollection 类的对象不能为转换为字符串
这是我的产品"实体和方法中的价格"属性:
/*** @ORM\OneToMany(targetEntity=Prices::class,mappedBy=product")* @Groups({"products:read"})*/私人$价格；/*** @return 收藏|价格[]*/公共函数 getPrices():集合{返回 $this->prices;}公共函数 addPrice(Prices $price): self{如果 (!$this->prices->contains($price)) {$this->prices[] = $price;$price->setProduct($this);}返回 $this;}公共函数 removePrice(Prices $price): self{如果 ($this->prices->removeElement($price)) {//将拥有方设置为 null(除非已经更改)if ($price->getProduct() === $this) {$price->setProduct(null);}}返回 $this;}我感觉我可能需要对事件侦听器做一些事情，但我真的不知道如何去做，因为我之前没有真正与他们合作过.
非常感谢您的帮助
您可以为 Prices 实体创建一个表单，然后在您的产品中使用它
CollectionField::new('prices')->hideOnIndex()->setLabel('布鲁托价格')->setTemplatePath('price.html.twig')->setFormTypeOptions(['标签' =>错误的，'delete_empty' =>真的，'by_reference' =>错误的，])-> setEntryIsComplex(false)->setCustomOptions(['允许添加' =>真的，'允许删除' =>错误的，'entryType' =>PricesType::class,//你的价格表格类在这里'showEntryLabel' =>错误的，]);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,
])
;
