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
- Locate the
superset_config.py
File
The language settings for Apache Superset are typically controlled through thesuperset_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.
- Open the File
Use a text editor (e.g.,vim
,nano
, or any preferred code editor) to open thesuperset_config.py
file.
Step 2: Define the Default Language
- Add or Modify the
BABEL_DEFAULT_LOCALE
Setting
To change the default language, add or edit the following line in thesuperset_config.py
file:Replace
'xx'
with the language code for your desired language. Some commonly used codes include:en
for Englishes
for Spanishfr
for Frenchzh
for Chinese
- Example: If you want the default language to be Spanish, the line should look like this:
Step 3: Restart the Superset Server
After updating the configuration file, restart your Apache Superset server to apply the changes:
- Stop the server if it’s running:
- Start the server again:
This ensures the new language setting is loaded.
Step 4: Verify the Changes
- Log in to your Superset instance.
- Navigate through the interface to confirm that the language has changed to your preferred setting.
- 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.
