I am currently running an outdated version of Apache Superset 0.20.4. The Superset DB contains a substantial amount of slices and dashboards. I would like to update my version.
Can I just run an upgrade from pip? Is any of you aware of any backward incompatibility that would prevent me from reading the Superset DB after the update?
Answering my own question, there is no problem in upgrading but one has to run the DB migration superset db upgrade.

We want to upgrade our old superset installation (0.19.0) to the latest version (1.3.2 or 1.4.0), and are just wondering whether there is anything we need to do to migrate the existing dashboards?
All meta data sits in AWS RDS database. Do we need to make any change in the DB, or just simply connect to it from the new Superset version?
Export all the dashboards, connect the to the database from the new supersert version and import the dashboards to the new environment
I tried to connect to Sybase database from Django using sqlanydjango, but
I have stuck. One answer saying that
sqlany-django is no longer maintained; it was last updated in May 2016.
What is the other possibility to connect to Sybase database?
OS Ubuntu 18.04
django 2.2.4
Sybase is no longer maintained and it's not supported by Django. I recommend using one of the supported databases:
PostgreSQL
MariaDB
MySQL
Oracle
SQLite
Personally, I would recommend using PostgreSQL - I think it's the most advanced database. If you use it, I would recommend using version 13, since version 14 is still new and I think it's not officially supported by Django yet. It's always a good practice to use the previous major release. Also with Django, I recommend upgrading to the latest major release only about 4 to 6 months after its initial release. So for today, this means using Django 3.2 (latest minor release, currently 3.2.11).
You can use django-environ to define the database you are using in settings.
You could use the freetds module. GitHub repository was active 5 days ago, it aims to provide support for sybase and MSQL Server.
I used it with MSQL
You can download it from there, and installing with the instruction on this link (Sybase python module website)
Then you can test your installation using these steps
You can also try different Django version.
If this doesn't show anything wrong, and Django still won't connect to your DB, you can try to edit Django's source files so the ImproperlyConfigured exception doesn't raise (REALLY REALLY RISKY, DO A BACK UP OF YOUR DB) or migrate your Sybase to a supported database.
You can use pyodbc.
To install this.
Pip install pyodbc
import pyodbc
cnxn = pyodbc.connect(‘DRIVER={Devart ODBC Driver for ASE};Server=myserver;Port=myport;Database=mydatabase;User ID=myuserid;Password=mypassword;String Types=Unicode’)

Is there a package that is currently installed in the Python SDK that would allow me to connect to a mysql source? If not, I'll need to add in a requirements.txt file, which I'm trying to eliminate, as it drastically increases the setup time for things.
Update: I suppose pandas can, though I believe it needs an additional 'binding' for each sql source it connects to if I'm not mistaken?.
Since you are trying to connect to MySQL you need a specific client that will establish a channel between you and the database. Therefore, you will have to use the requirements.txt file to install this library.
You can refer to this StuckOverflow link that has a similar question. The answer specifies that "You must install a MySQL driver before doing anything. Unlike PHP, Only the SQLite driver is installed by default with Python. ...".
So only the SQLite driver is installed with Python SDK, not the MySQL one.
I started developing a django webapp which will need to connect to oracle databases. But using oracle with django requires an Oracle client if I'm not mistaken which is platform dependant. If it's not possible to create a portable webapp with django and oracle, could the app use an oracle client install on the machine where the app is running?
Thanks
What do you mean by "portable" exactly ? You can definitely move your Django folder around, especially if you use SQLite for database storage, since a SQLite database is just a file.
All you'll need is Python on the target machine, access to the command line and the ability to install your dependencies with pip.
Then you can just run your webapp with python manage.py runserver.
If this doesn't answer your question, please give more info.
