Je viens de mettre à jour mon python de 3.9.1 à 3.9.4. Quand j'ai essayé de lancer le serveur. La console m'a donné un avertissement pour ceci :
WARNINGS:
learning_logs.Entry: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'.
HINT: Configure the DEFAULT_AUTO_FIELD setting or the LearningLogsConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'.
learning_logs.Topic: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'.
HINT: Configure the DEFAULT_AUTO_FIELD setting or the LearningLogsConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'.
No changes detected in app 'learning_logs'
Puis-je savoir comment résoudre ce problème ? J'ai lu la documentation à ce sujet, mais je ne comprends pas comment cette partie cette page s'y rapporte.
