pip install django-pdf-actions
```

#### From Source
If you want to install the latest development version:
```bash
git clone https://github.com/ibrahimroshdy/django-pdf-actions.git
cd django-pdf-actions
pip install -e .
```

### 2. Add to INSTALLED_APPS

Add 'django_pdf_actions' to your INSTALLED_APPS setting:

```python
INSTALLED_APPS = [
    ...
    'django_pdf_actions'
]
```

### 3. Run Migrations

```bash
python manage.py migrate
```

### 4. Set up Fonts

The package uses fonts from your project's `static/assets/fonts` directory. The default font is DejaVu Sans, which provides excellent Unicode support.

To use custom fonts:
1. Create the fonts directory if it doesn't exist:
   ```bash
   mkdir -p static/assets/fonts
   ```
2. Install the default font (DejaVu Sans):
```bash
python manage.py setup_fonts
```
3. Add custom fonts (optional):
   ```bash
   # Example: Installing Roboto font
   python manage.py setup_fonts --font-url "https://github.com/google/fonts/raw/main/apache/roboto/Roboto-Regular.ttf" --font-name "Roboto-Regular.ttf"

   # Example: Installing Cairo font for Arabic support
   python manage.py setup_fonts --font-url "https://github.com/google/fonts/raw/main/ofl/cairo/Cairo-Regular.ttf" --font-name "Cairo-Regular.ttf"
   ```

#### Font Directory Structure
After setup, your project should have this structure:
```
your_project/
├── static/
│   └── assets/
│       └── fonts/
│           ├── DejaVuSans.ttf
│           ├── Roboto-Regular.ttf (optional)
│           └── Cairo-Regular.ttf (optional)
```

### 5. Verify Installation

To verify the installation:
1. Start your Django development server
2. Navigate to the Django admin interface
3. Select any model with list view
4. You should see "Export to PDF (Portrait)" and "Export to PDF (Landscape)" in the actions dropdown

### 6. Add to Your Models

Import and use the PDF export actions in your admin.py:

```python
from django.contrib import admin
from django_pdf_actions.actions import export_to_pdf_landscape, export_to_pdf_portrait
from .models import YourModel

@admin.register(YourModel)
class YourModelAdmin(admin.ModelAdmin):
    list_display = ('field1', 'field2', ...)  # Your fields here
    actions = [export_to_pdf_landscape, export_to_pdf_portrait]
```
