User Roles
The platform supports three user types:
1. **Students** - Browse and search hostels
2. **Hostel Owners** - List and manage properties
3. **Admins** - Platform management
Development Guidelines
1. Code Structure
Follow Django MVT (Model-View-Template) patternKeep models in `hostels/models.py`Use class-based views where appropriateOrganize templates in logical subdirectoriesKeep static files properly namespaced2. Database Operations
**Common Django commands:**
```bash
python manage.py makemigrations # Create migration files
python manage.py migrate # Apply migrations
python manage.py createsuperuser # Create admin user
python manage.py runserver # Start dev server (http://localhost:8000)
```
**Admin access:** http://localhost:8000/admin (credentials: admin/admin123)
3. Frontend Development
Use Tailwind CSS utility classes for stylingEnsure responsive design for mobile/tablet/desktopIntegrate Django template tags with TailwindKeep JavaScript minimal and organized4. Feature Implementation Priority
When implementing features, follow this order:
**Phase 1 - Core Listings:**
Hostel listing templates (list view, detail view, grid layout)Advanced search and filtering (location, price, amenities)Pagination for listings**Phase 2 - Media & Maps:**
Image upload functionality with validationMultiple image support per hostelGoogle Maps API integration for location displayInteractive map markers for hostel locations**Phase 3 - Communications:**
Email notifications (inquiry, booking confirmation)Contact form integrationOwner messaging system**Phase 4 - Booking (Future):**
Reservation systemPayment integrationBooking management dashboard5. Best Practices
**Models:**
Use appropriate field types (CharField, TextField, ImageField, etc.)Add `verbose_name` and `help_text` for clarityImplement `__str__()` methodsUse validators for data integrityAdd indexes for frequently queried fields**Views:**
Use Django's built-in generic views when possibleImplement proper permission checksHandle form validation gracefullyReturn appropriate HTTP responses**Templates:**
Extend base templates to reduce duplicationUse template inheritance effectivelyInclude CSRF tokens in formsImplement proper error handling**Security:**
Validate and sanitize all user inputsUse Django's built-in protections (CSRF, XSS, SQL injection)Implement proper authentication checksSecure media uploads with file type validation**Performance:**
Use `select_related()` and `prefetch_related()` for queriesImplement caching where appropriateOptimize database queries (avoid N+1 problems)Compress and optimize uploaded images6. Development Workflow
1. **Feature Planning**: Break down requirements into small, testable units
2. **Model Changes**: Update models → create migrations → apply migrations
3. **Views & Forms**: Implement business logic and form handling
4. **Templates**: Create responsive, user-friendly interfaces
5. **Testing**: Test manually on dev server
6. **Admin Integration**: Register models and configure admin interface
7. Code Style
Follow PEP 8 Python style guideUse meaningful variable and function namesAdd docstrings to functions and classesKeep functions small and focusedComment complex logic only8. Deployment Considerations
**Production checklist:**
Switch to PostgreSQL databaseSet `DEBUG = False`Configure `ALLOWED_HOSTS`Set up static file servingConfigure media file storageImplement proper loggingSet secure environment variablesEnable HTTPSCommunication Style
Keep responses concise and actionableFocus on systematic, step-by-step developmentProvide code examples when helpfulReference Django documentation for complex topicsHighlight potential issues before they occurExample Usage
**"Add a featured hostel carousel to the homepage"**
1. Update model with `is_featured` boolean field
2. Create and apply migration
3. Update view to query featured hostels
4. Implement Tailwind carousel component in template
5. Add admin filter for featured status
**"Implement Google Maps on hostel detail page"**
1. Add Google Maps API key to settings
2. Create map template partial with JavaScript
3. Pass hostel coordinates to template context
4. Include map partial in detail view
5. Style map container with Tailwind
