Merci à tous de toujours partager vos connaissances ici.

J'ai un problème avec le comptage d'un objet dans Django. J'apprends et travaille actuellement sur un système RH de base et j'ai déjà mis en place mes points de vue, mes modèles et autres. Je prévois d'avoir une interface qui me permettra d'imprimer le nombre d'employés en fonction du sexe. Celui que j'ai actuellement mis en place augmente le nombre d'hommes et de femmes chaque fois que je crée un nouvel employé. S'il vous plaît, comment puis-je corriger cette anomalie?
