исправление в settings.py:
DATABASES={
'default':
{
'ENGINE':'django.db.backends.oracle',
'NAME':'servicename', # must be the servicename eg. dbname_high,dbname_low,dbname_medium etc.
'USER':'ADMIN',
'PASSWORD':'bhouguspassword',#Please provide the db password here but it can cause issue if you were using '@'
}
}
путь:
ls -lart /usr/lib/oracle/21/
Я разархивировал кошелек в папке ?/network/adminи изменил групповую настройку на apache с помощью chown -R :apache /usr/lib/oracle/21/убедитесь, что у вас правильно настроен TNS_ADMIN, LD_LIBRARY_PATH
python manage.py migrate
