DjangoCon 2021 | KEYNOTE Spreading our tentacles taking a Django app global | Frederike Jaeger

Introduction

This tutorial will guide you through the process of adapting a Django application for a global audience. Inspired by a talk from DjangoCon 2021, we'll explore how to modify your app to support multiple clients in different countries while maintaining its core functionality. This is crucial for businesses looking to expand internationally, especially in sectors like green energy.

Step 1: Understand Your Current Application

Before making any changes, it’s essential to have a thorough understanding of your existing Django app.

• Review the current features and functionalities.
• Identify the specific needs of your primary audience.
• Document any assumptions made during the initial development that may not hold true for new markets.

Step 2: Identify Localization Requirements

Localization goes beyond translation; it includes adapting the app's functionality to meet local needs.

• Determine the languages that need to be supported.
• Research local regulations and standards, especially in industries like energy.
• Consider currency, date formats, and units of measurement that vary by region.

Step 3: Refactor for Multi-Tenancy

To allow multiple clients to use the same application, you'll need to implement a multi-tenancy architecture.

• Decide on a strategy for data isolation, such as:
  • Single database with tenant ID
  • Separate databases for each tenant
• Use Django packages like django-tenant-schemas to manage multi-tenancy effectively.

Step 4: Implement Internationalization

Django provides built-in support for internationalization (i18n).

• Enable i18n in your Django settings:

  USE_I18N = True
  

• Mark strings for translation in your code:

  from django.utils.translation import gettext as _
  

• Create translation files using:

  python manage.py makemessages -l [language_code]
  

• Compile translations with:

  python manage.py compilemessages
  

Step 5: Test Across Different Regions

Testing is crucial to ensure that your app works well in various locales.

• Set up testing environments that simulate different regions.
• Use automated tests to check for localization issues.
• Gather feedback from users in different countries to identify any usability problems.

Step 6: Monitor and Iterate

Once your app is live in new markets, continuous monitoring and iteration will be key to its success.

• Use analytics to track user engagement and identify areas for improvement.
• Be open to user feedback and make necessary adjustments.
• Regularly update your app to accommodate changes in local regulations or user needs.

Conclusion

Transforming your Django app for a global audience requires careful planning and execution. By understanding your current application, implementing multi-tenancy, and focusing on localization and internationalization, you can effectively expand your reach. Remember to test thoroughly and be responsive to user feedback to ensure ongoing success in new markets. Your next steps should involve applying these strategies to your existing codebase and preparing for an international rollout.
