Development #36608
Mis à jour par Lauréline Guérin il y a plus de 4 ans
il y a pas mal de warnings de ce type dans les migrations de passerelle:
<pre>
RemovedInDjango20Warning: on_delete will be a required arg for ForeignKey in Django 2.0. Set it to models.CASCADE on models and in existing migrations if you want to maintain the current default behavior. See https://docs.djangoproject.com/en/1.11/ref/models/fields/#django.db.models.ForeignKey.on_delete
</pre>
solution proposée: ajouter des on_delete un peu partout pour être django 2 compatible
traiter aussi les autres RemovedInDjango20Warning. exemple:
<pre>
RemovedInDjango20Warning: Old-style middleware using settings.MIDDLEWARE_CLASSES is deprecated. Update your middleware and use settings.MIDDLEWARE instead.
</pre>
