Ma situation est très difficile. Je construis un clone de liste de naissance à l'aide de Scraper, mais j'ai du mal à le coder car je suis inexpérimenté. J'ai créé avec succès une page d'administration avec plusieurs formulaires pour insérer des sites, des catégories et des formulaires de liens où vous pouvez spécifier sur quel lien doit être exploré et à quel site et catégorie il sera lié. Cependant, ajouter quelque chose comme ceci est acceptable, mais le supprimer ne l'est pas..
Mes sites, catégories et liens sont affichés sur ma page d'administration, avec un bouton de saisie et de suppression pour chaque élément. Lorsque je supprime le dernier élément de la ligne, le premier élément est supprimé. Lorsque je veux supprimer quelque chose d'autre, Laravel lève une exception et essaie de lire la propriété sur null, ce qui signifie qu'elle n'existe plus. Lorsque je vide avant de supprimer la fonction et de mourir, chaque élément de chaque liste a l'identifiant "1". C'est pourquoi il supprime le premier élément consécutif. Quelqu'un peut-il m'aider?
Je pense que cela est dû au fait que l'identifiant demandant la suppression de l'élément est récupéré à partir de l'URL et que l'identifiant donné dans l'URL est l'identifiant de l'utilisateur qui est 1. Donc, si quelqu'un peut me donner un indice pour m'assurer que je peux donner l'identifiant de l'utilisateur d'une manière différente. fais-moi savoir! Mon code :

Remplacez ce code
Avec ça
| Url | Filter selector | Website | Categorie | ||
| {{ $link->url }} | {{ $link->main_filter_selector }} | {{ $link->website->title }} | {{ $link->category->title }} |
Votre destroyLink() méthode devrait contenir ceci
public function destroyLink(Request $request)
{
$id = $request->id;
$link = Link::find($id);
$link->delete();
return back();
}
