Side Note: When posting code here, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted.
(I have taken the liberty of modifying your post for this, please remember to do this in the future.)

— From translate.google.com —

J’ai du mal à comprendre comment cette erreur pourrait être causée par l’administrateur sur ce modèle.

Avez-vous apporté des modifications récentes à vos modèles ? Si oui, avez-vous exécuté makemigrations et migrate ?
Toutes les migrations ont-elles été appliquées ? (Pouvez-vous afficher la sortie d’une commande manage.py showmigrations ?)

Cela se produit-il uniquement avec cette instance spécifique de CanalUSSD ou cela se produit-il à chaque fois ?

Pouvez-vous recréer le problème et publier le message d’erreur complet avec le traceback de la console du serveur, et non la page Web de résumé des erreurs ?

Quel moteur de base de données utilisez-vous ?

— The original English —

I’m having a difficult time seeing how this error could be caused by the Admin on this model.

Have you made any recent changes to your models? If so, have you run makemigrations and migrate?
Have all migrations been applied? (Can you show the output of a manage.py showmigrations command?)

Does this happen only with this specific instance of CanalUSSD or does it happen every time?

Can you recreate the issue and post the complete error message with the traceback from the server console, and not the error summary web page?

What database engine are you using?
