Django: la relation n'existe pas

Question

J'ai extrait les mises à jour de myproject de bitbucket et j'ai essayé les commandes suivantes 'python3 manage.py makemigrations', 'python3 manage.py migrate vehicle', 'python3 manage.py migrate'. Mais je reçois l'erreur suivante. L'application véhicule est nouvelle et certains de ses modèles utilisent des clés étrangères provenant d'autres applications qui ont été migrées auparavant et qui se trouvent dans la base de données. J'ai essayé différentes façons, mais je ne trouve pas la solution. J'utilise django-1.7.4 J'apprécie tout conseil.

pour ce que je l'ai vu, j'essaye de validade le AdvancedVehicleSearchForm avant d'exécuter la migration, essayez passer le formulaire lié au véhicule à l'application du véhicule de la manière dont django peut faire la migration en premier. Je ne peux pas vous aider plus pour les fichiers que vous montrez là désolé. J'espère que cela vous aide en quelque sorte
