How to Change the Default Language in Apache Superset 4.0.2

Apache Superset is a powerful open-source business intelligence and data visualization platform. With the release of version 4.0.2, the application continues to evolve, offering enhanced features and improved usability. One such feature is its multi-language support, which allows users to change the default language for a more personalized experience.

If you’re using Apache Superset 4.0.2 and want to change the default language, follow this step-by-step guide:

Step 1: Access Configuration Files

1. Locate the superset_config.py File
   The language settings for Apache Superset are typically controlled through the superset_config.py file.
   • By default, this file is located in the Superset configuration directory.
   • If it doesn’t exist, you may need to create it in your working directory.
2. Open the File
   Use a text editor (e.g., vim, nano, or any preferred code editor) to open the superset_config.py file.

Step 2: Define the Default Language

1. Add or Modify the BABEL_DEFAULT_LOCALE Setting
   To change the default language, add or edit the following line in the superset_config.py file:
   python

   Copy code

   BABEL_DEFAULT_LOCALE = 'xx'


   Replace 'xx' with the language code for your desired language. Some commonly used codes include:

   • en for English
   • es for Spanish
   • fr for French
   • zh for Chinese
2. Example: If you want the default language to be Spanish, the line should look like this:
   python

   Copy code

   BABEL_DEFAULT_LOCALE = 'es'


Step 3: Restart the Superset Server

After updating the configuration file, restart your Apache Superset server to apply the changes:

1. Stop the server if it’s running:
   bash

   Copy code

   superset stop

2. Start the server again:
   bash

   Copy code

   superset start


This ensures the new language setting is loaded.

Step 4: Verify the Changes

1. Log in to your Superset instance.
2. Navigate through the interface to confirm that the language has changed to your preferred setting.
3. If the changes are not reflected, double-check the configuration and restart the server again.

Optional: Enable User-Specific Language Preferences

If you want individual users to choose their preferred language, ensure the LANGUAGES setting in the superset_config.py file includes all supported languages:

Troubleshooting Tips

• Language Not Changing: Ensure that the BABEL_DEFAULT_LOCALE value is correctly set and matches a supported language code.
• Missing Translations: Not all features may be fully translated into every language. You may need to contribute translations to the Apache Superset project.
• Server Issues: Check the server logs for errors if the application fails to start after making changes.

Conclusion

Changing the default language in Apache Superset 4.0.2 is a straightforward process that enhances the user experience for non-English-speaking users. By updating the superset_config.py file and restarting the server, you can customize the platform to better suit your team’s linguistic needs.
