Question :
J'ai utilisé $push pour insérer un commentaire[0] dans les données dans mongo
Pour certaines raisons, je ne veux pas d'une certaine valeur dans le commentaire. Quelle opération dois-je utiliser pour supprimer un élément du tableau (l'élément du tableau dans cette question est également un tableau)
Commande de mise à jour des données Mongodb. J'ai essayé certaines méthodes, mais elles n'ont pas fonctionné. Veuillez me donner quelques conseils !
