Pré-remplir un formulaire à partir de données d'une autre application avec Django

Bonjour tout le monde,

Je suis entrain de développer mon application web depuis maintenant près de 6 mois et je rencontre un problème pour pré-remplir un de me formulaires avec les données provenant d'un autre modèle.

Je possède plusieurs tables et ici sont mises en jeu 2 tables : Person et BirthCertificate.

La table Person permet de créer toute une fiche d'information sur un individu (nom, prénom, date de naissance, adresse, ... et un numéro unique)

La table BirthCertificate doit pouvoir lire le numéro unique écrit par l'utilisateur et pré-remplir le formulaire avec les données contenues dans la table Person pour le numéro unique donné.

Donc voici mes modèles Person et BirthCertificate :
