The previous fix by @theoryshaw had the correct conclusion but had some
issues:
1. Don't implement anything that fetches IFC data in the UI draw calls.
This historically has lead to race conditions and crashes. The data
classes are much preferred.
2. Rather than load the inapplicable attribute then selectively omit it
in the UI, it's preferred to just never load it in the first place.
Reuse tool.Geometry.duplicate_ifc_objects because that's where all
duplication logic should stay instead of half reimplementing it every
time which introduces subtle bugs.
I generally like to minimise knobs and dials, so this is now part of the
wizard but now defaults to a "NONE" unit. You also now have the option
to choose "NONE" for area / volume units which makes things consistent.
Enum names also match the IFC lowercase convention for conversion based
units. This also simplifies the core logic and treats all units the same
way instead of special cases for each unit type. (length is still
special and required in Bonsai as we are inherently graphical)
- is_skipped is calculated upstream instead of reimplementing logic
- the viewer now shows cardinality (not just in edit mode) to make it
clear what the requirements are
- prohibited specs are not allowed to have any requirements, so that
section is hidden
- failed prohibited specs now shows list of failed (applicable)
entities
The report_specification() method in the Json reporter class was raising
an UnboundLocalError when processing IDS specifications with certain
minOccurs/maxOccurs combinations that weren't explicitly handled.
Problem:
The cardinality variable was only assigned for three specific cases:
- minOccurs=1, maxOccurs="unbounded" → "required"
- minOccurs=0, maxOccurs="unbounded" → "optional"
- minOccurs=0, maxOccurs=0 → "prohibited"
However, the IDS schema allows other valid combinations such as:
- minOccurs=0, maxOccurs=1 (commonly used for optional specifications)
- minOccurs=1, maxOccurs=1 (exactly one occurrence required)
- Any other valid XML Schema cardinality values
When processing IDS files with these combinations, the cardinality
variable remained unassigned, causing an UnboundLocalError at line 382
when attempting to use it in ResultsSpecification().
Solution:
Added fallback logic to handle all valid IDS cardinality combinations:
- If minOccurs >= 1: cardinality = "required" (must occur at least once)
- Otherwise (minOccurs == 0): cardinality = "optional" (may occur)
This maintains semantic compatibility with the existing codebase, which
expects cardinality to be one of the semantic strings ("required",
"optional", "prohibited") rather than numeric ranges. This is critical
for:
- HTML template rendering (line 457: .capitalize())
- Conditional logic for skipped specs (line 454)
- UI rendering for prohibited specs (line 456)
Testing:
- Tested with IDS file containing minOccurs=0 without explicit maxOccurs
(defaults to 1 per XML Schema specification)
- Validation now completes successfully without UnboundLocalError
- HTML report generation works correctly with semantic cardinality labels
- Maintains backward compatibility with existing IDS files
Fixes: Validation failure when using valid IDS cardinality combinations
* black .
* add typing
* move function
* add get_class_relations
* add test for class relation
