问题描述
我有一个带有图片的实体,并且我正在使用EasyAdmin 3.0和VichUploader 1.14在管理控制台中上传图片。我的问题是我无法在管理控制台中显示图像。我怎样才能做到这一点 ? 这是我的实体:
class Question
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
* @Groups({"question"})
*/
private $id;
/**
* @ORM\Column(type="text",nullable=true)
* @Groups({"question"})
*/
private $title;
/**
* NOTE: This is not a mapped field of entity Metadata,just a simple property.
*
* @Vich\UploadableField(mapping="stand_image",fileNameProperty="imageName",size="imageSize")
*

private $imageFile;

public function setimageFile(?File $imageFile = null): void

这是我的vich_uploader.yaml文件:
vich_uploader:
db_driver: orm
mappings:
question_image:
uri_prefix: /images/questions
upload_destination: '%kernel.project_dir%/public/images/questions'
namer: Vich\UploaderBundle\Naming\OrignameNamer
这是我的EasyAdmin的CRUD控制器:
class QuestionCrudController extends AbstractCrudController
{
public static function getEntityFqcn(): string
{
return Question::class;
}
public function configureCrud(Crud $crud): Crud
{
return $crud
// Les labels utilisés pour faire référence à l'entité dans les titres,les boutons,etc.
->setEntityLabelInSingular('question')
->setEntityLabelInPlural('questions')
// Le titre visible en haut de la page et le contenu de l'élément <title>
// Cela peut inclure ces différents placeholders : %entity_id%,%entity_label_singular%,%entity_label_plural%
->setPageTitle('index','Liste des %entity_label_plural%')
->setPageTitle('new','Créer une %entity_label_singular%')
->setPageTitle('edit','Modifier la %entity_label_singular% <small>(#%entity_id%)</small>')
// Définit le tri initial appliqué à la liste
// (l'utilisateur peut ensuite modifier ce tri en cliquant sur les colonnes de la table)
->setDefaultSort(['id' => 'ASC'])
;
}
public function configureActions(Actions $actions): Actions
{
return $actions
->update(Crud::PAGE_INDEX,Action::NEW,function (Action $action) {
return $action->setLabel('Ajouter une %entity_label_singular%');
})
->update(Crud::PAGE_INDEX,Action::EDIT,function (Action $action) {
return $action->setLabel('Modifier');
})
->update(Crud::PAGE_INDEX,Action::DELETE,function (Action $action) {
return $action->setLabel('Supprimer');
})
->update(Crud::PAGE_NEW,Action::SAVE_AND_RETURN,function (Action $action) {
return $action->setLabel('Créer');
})
->update(Crud::PAGE_NEW,Action::SAVE_AND_ADD_ANOTHER,function (Action $action) {
return $action->setLabel('Créer et ajouter une autre %entity_label_singular%');
})
->update(Crud::PAGE_EDIT,function (Action $action) {
return $action->setLabel('Sauvegarder les changements');
})
->update(Crud::PAGE_EDIT,Action::SAVE_AND_CONTINUE,function (Action $action) {
return $action->setLabel('Sauvegarder et continuer à modifier');
})
->update(Crud::PAGE_DETAIL,function (Action $action) {
return $action->setLabel('Supprimer');
})
->update(Crud::PAGE_DETAIL,Action::INDEX,function (Action $action) {
return $action->setLabel('Retour à la liste');
})
->update(Crud::PAGE_DETAIL,function (Action $action) {
return $action->setLabel('Modifier');
})
;
}
public function configureFields(string $pageName): iterable
{
return [
IdField::new('id','Id')->hideOnForm(),TextField::new('title','Intitulé'),ImageField::new('imageFile','Image')
->setFormType(VichImageType::class)
->setBasePath('/public/images/questions'),TextField::new('answer','Réponse'),TextField::new('explanation','Explications'),IntegerField::new('level','Niveau'),AssociationField::new('game','Jeu'),];
}
}
Here's the result in my admin console. What I'd want is that the image appears instead of null.
解决方法
您必须仅在“表单”页面上显示imageFile(带有-> onlyOnForms()),而在索引页面上必须显示imageName(带有onlyOnIndex()),并且设置与VichUploader配置中相同的路径(/ images / questions)
请参见以下示例:
public function configureFields(string $pageName): iterable
{
return [
ImageField::new('imageName','Image')
->onlyOnIndex()
->setBasePath('/images/questions'),ImageField::new('imageFile','Image')
->onlyOnForms()
->setFormType(VichImageType::class)
];
}
