# Django Extensions

This project has django-extensions installed. Use these commands to understand and interact with the Django project.

## Introspection

### Show URL Routes
```bash
python manage.py show_urls
```

### List Model Information
```bash
# All models
python manage.py list_model_info

# Specific model with signatures and field classes
python manage.py list_model_info --model <app.Model> --signature --field-class

# All methods including private
python manage.py list_model_info --model <app.Model> --all-methods --signature
```

### Print Settings
```bash
# All settings
python manage.py print_settings --format=pprint

# Wildcards supported
python manage.py print_settings AUTH*
python manage.py print_settings DATABASE*
python manage.py print_settings *_DIRS
```

### Show Permissions
```bash
python manage.py show_permissions
python manage.py show_permissions <app_label>
```

### Show Template Tags
```bash
python manage.py show_template_tags
```

## Development

### Enhanced Shell (shell_plus)
```bash
python manage.py shell_plus
python manage.py shell_plus --print-sql
```
Auto-imports all models. Use `--dont-load app1` to skip apps.

### Enhanced Dev Server (runserver_plus)
```bash
python manage.py runserver_plus
python manage.py runserver_plus --print-sql
```
Includes Werkzeug debugger for interactive debugging.

## Database

### SQL Diff (Compare Models to Schema)
```bash
python manage.py sqldiff -a        # SQL differences
python manage.py sqldiff -a -t     # Text differences (readable)
```

## Script Execution

### Run Scripts with Django Context
```bash
python manage.py runscript <script_name>
python manage.py runscript <script_name> --script-args arg1 arg2
python manage.py runscript <script_name> --traceback
```
Scripts in `scripts/` directory must define a `run()` function.

## Profiling

### Profile Server Requests
```bash
python manage.py runprofileserver --prof-path=/tmp/profiles
python manage.py runprofileserver --use-cprofile --prof-path=/tmp/profiles
python manage.py runprofileserver --kcachegrind --prof-path=/tmp/profiles
```

## Notes

- Model notation: `app.ModelName` (e.g., `core.EmailAccount`, `metabox.Thread`)
- Settings wildcards: `AUTH*`, `*_DIRS`, `DATABASE*`
- Commands run from project root
