New Features
Complete UI Refresh (#12128)
The NetBox user interface has been completely refreshed and updated. This massive effort entailed:
- Refactoring the base HTML templates
- Moving from Boostrap 5.0 to Bootstrap 5.3
- Adopting the Tabler UI theme
- Replacing slim-select with Tom-Select
- Displaying additional object attributes in dropdown form fields
- Enabling opt-in HTMX-powered navigation (see #14736)
- Widespread cleanup & standardization of UI components
Dynamic REST API Fields (#15087)
The REST API now supports specifying which fields to include in the response data. For example, the response to a request for
GET /api/dcim/sites/?fields=name,status,region,tenant
will include only the four specified fields in the representation of each site. Additionally, the underlying database queries effected by such requests have been optimized to omit fields which are not included in the response, resulting in a substantial performance improvement.
Strawberry GraphQL Engine (#9856)
The GraphQL engine has been changed from using Graphene-Django to Strawberry-Django. Changes include:
- Queryset Optimizer - reduces the number of database queries when querying related tables
- Updated GraphiQL Browser
- The format for GraphQL query filters and lookups has changed. Please see the GraphQL documentation for details and examples.
Advanced Form Rendering Functionality (#14739)
New resources have been introduced to enable advanced form rendering without a need for custom HTML templates. These include:
- FieldSet - Represents a grouping of form fields (replaces the use of lists/tuples)
- InlineFields - Multiple fields rendered on a single row
- TabbedGroups - Fieldsets rendered under navigable tabs within a form
- ObjectAttribute - Renders a read-only representation of a particular object attribute (for reference)
Legacy Admin UI Disabled (#12325)
The legacy admin user interface is now disabled by default, and the few remaining views it provided have been relocated to the primary UI. NetBox deployments which still depend on the legacy admin functionality for plugins can enable it by setting the DJANGO_ADMIN_ENABLED
configuration parameter to true.
