* Implement {module} position inheritance for nested module bays (#19796)
Enables a single ModuleType to produce correctly named components at any
nesting depth by resolving {module} in module bay position fields during
tree traversal. The user controls the separator through the position
field template itself (e.g. {module}/1 vs {module}-1 vs {module}.1).
Model layer:
- Add _get_inherited_positions() to resolve {module} in positions as
the module tree is walked from root to leaf
- Update _resolve_module_placeholder() with single-token logic: one
{module} resolves to the leaf bay's inherited position; multi-token
continues level-by-level replacement for backwards compatibility
Form layer:
- Update _get_module_bay_tree() to resolve {module} in positions during
traversal, propagating parent positions through the tree
- Extract validation into _validate_module_tokens() private method
Tests:
- Position inheritance at depth 2 and 3
- Custom separator (dot notation)
- Multi-token backwards compatibility
- Documentation for position inheritance
Fixes: #19796
* Consolidate {module} placeholder logic into shared utilities and add API validation
Extract get_module_bay_positions() and resolve_module_placeholder() into
dcim/utils.py as shared routines used by the model, form, and API serializer.
This eliminates duplicated traversal and resolution logic across three layers.
Key changes:
- Add position inheritance: {module} tokens in bay position fields resolve
using the parent bay's position during hierarchy traversal
- Single {module} token now resolves to the leaf bay's inherited position
- Mismatched token count vs tree depth now raises ValueError instead of
silently producing partial strings
- API serializer validation uses shared utilities for parity with the form
- Fix error message wording ("levels deep" instead of "in tree")
Replace direct attribute access with hasattr() to prevent AttributeError
when the virtual_circuit_termination relation doesn't exist on the
object.
Fixes#21808
Fix context variable references in VirtualChassMembersPanel add action
to use 'virtual_chassis' instead of 'object'. Add safe checks for
master_id existence to prevent errors when master is not set.
Fixes#21810
Align the plugin search example with the recommended registration
pattern used in the general search documentation and NetBox core.
Replace the legacy `indexes = [...]` example with decorator-based
registration to make the preferred approach clearer for plugin authors.
Introduce `VirtualMachineType` to classify virtual machines and apply
default platform, vCPU, and memory values when creating a VM.
This adds the new model and its relationship to `VirtualMachine`, and
wires it through forms, filtersets, tables, views, the REST API,
GraphQL, navigation, search, documentation, and tests.
Explicit values set on a virtual machine continue to take precedence,
and changes to a type do not retroactively update existing VMs.
Update change data diff styling with CSS custom properties, better color
contrast, and consistent borders. Replace btn-group with card-actions
for navigation buttons and improve spacing.
Mark provider, member, and action_object columns as non-orderable since
they use complex accessors that cannot be sorted. Add regression tests
to verify all orderable columns render without exceptions.
Fixes table rendering errors when attempting to sort columns with
multi-level field accessors that don't support database ordering.
Add ChangelogMessageMixin to DeviceBulkAddComponentForm and capture
changelog_message during bulk component creation. Ensure message is
applied to each created component instance. Add test coverage for
changelog message propagation.
