Usage

Template Creation

1. Navigate to NetBox's Ninja Templates section
2. Create a new template with:
   • Name: Template identifier
   • Output type: Text or Draw.io format
   • Object types: NetBox objects to associate with the template
   • Template code: Your Jinja2 template

Template Variables

• Access NetBox objects using object queries, e.g. {{ sites.first() }} or {{ regions.get(slug='region1') }}
• For object-specific templates, use {{ target_object }} to reference the current object

For detailed examples and use cases, see EXAMPLES.md.

Security Note

The plugin currently doesn't enforce object-level permissions in templates. Exercise caution when exposing data through templates, as users may access data beyond their normal permissions.
