Django can't add new item to another database on admin site
I'm using two databases to create an app and everything looks fine, I can change, delete the existing item but can't add new item to other database table on the admin site.

Proper directory structure for app versioning (Django)
I am currently starting work on a existing Django Project, and I need to make changes to the existing APIs. However, I can't change the existing code since old apps and sites have been using it, which might take a lot of time to change the structure, and might break current dependencies for those. So, for now, as asked, I need to maintain separate directories to change/review the existing code and achieve a versioning-like structure for Django apps. What might be the best way/structure to achieve this? The current structure is simple as given by django-admin startproject project_dir |___project_name_dir |___settings.py ... |___app_1_dir |___ __init__.py |___ views.py, serializers.py ... |___app_2_dir ... So, I need to like create versioning type structure for app_1 here. What might be the best approach to do that? -

How to use Django with a legacy mysql 5.7 database (troubles with mysqlclient version)
I started a new Django project, but it supposed to be working with a legacy MySQL 5.7 database. For now, I have Django project, with specified database in settings.py and mysqlclient installed. First thing i tried was python manage.py inspectdb --database dbname but I git this error: MySQLdb.OperationalError: (1043, 'Bad handshake') I already realized that this is because I have mysqlconnector for version 8.0, and it's not compatible with mysql 5.7. I also found out that when installing mysqlconnector, its version depends on what i have in mysql_config. If I type mysql_config --version I get 8.0.30 And I cannot understand why, because if I run sudo dpkg-reconfigure mysql-apt-config It says that I have currently selected mysql-5.7. What actually is mysql_config and why it's configured to a different version? How can I switch it to 5.7 and have right version of mysqlclient installed? Or are there any other ways to make mysql 5.7 and my Django project work together? -
