Common Mistakes to Avoid

Ignoring Virtual Environments

Many beginners neglect to use virtual environments when working with Django. This mistake can lead to dependency conflicts and version issues. To avoid this, always create a virtual environment using venv or virtualenv before starting a new project. This ensures that your project dependencies are isolated and manageable.

Hardcoding Settings

New developers often hardcode sensitive information, such as database credentials, directly into their Django settings. This practice can lead to security vulnerabilities. Instead, use environment variables or a separate configuration file to manage sensitive data securely.

Neglecting Database Migrations

Failing to run database migrations after making changes to models is a common pitfall. This can result in inconsistencies between the database schema and the application code. Always remember to run python manage.py makemigrations and python manage.py migrate after modifying models to keep everything in sync.

Overlooking Static Files Management

Beginners often overlook the management of static files, such as CSS and JavaScript. This can lead to broken layouts and functionality. To avoid this, ensure that you properly configure STATIC_URL and STATICFILES_DIRS in your settings, and use collectstatic for production environments.
