小唯快跑啊

實際上我在 create_user() 方法中有這個
user_settings = UserSettings(id=user.id, theme='default')
user.save()
user_settings.save()
根據上面的代碼 user.id 實際上是 null 。id 在用戶保存到數據庫后被分配。必須將其更改為下面才能使其正常工作
try:
user.save()
except Exception as e:
print(str(e))
raise Exception("Sorry couldn't save the user with email : " + user.email)
if check_user_exists(user.email):
user = get_user_by_email(email=user.email)
user_settings = UserSettings(id_id=user.id, theme='default')
user_settings.save()
else:
raise Exception("Sorry couldn't find the user with email : " + user.email)
