Computed attributes look metrics up in , but metrics migrated in the same run were only written to the mapping CSV. They could not be resolved until the next run. Add each migrated metric to the in-memory mappings right after writing the identifier relation.

Add a test that checks migrated metrics end up in .

risk: low

Summary by CodeRabbit

  • Bug Fixes
    • Migrated metrics now remain available through in-memory identifier mappings during the same migration run.
    • Subsequent migration steps can reliably resolve the cloud identifiers of metrics migrated earlier.

📝 Walkthrough

CloudMetric now registers legacy-to-cloud metric identifier mappings in the context when the mapping collection is available. A test verifies that migrated cloud metric IDs appear in the in-memory mappings.

Changes: Metric Mapping Registration

Layer / File(s) Summary
Register migrated metric identifiers
src/gooddata_legacy2cloud/metrics/cloud_metric.py, tests/test_metrics.py
CloudMetric adds the legacy and cloud metric identifiers to ctx.metric_mappings when the collection is available. The test checks that migrated cloud metric IDs appear in the mapping values.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 96703

The migration is operationally low risk, but the new test should verify the complete legacy-to-cloud association so mapping regressions are detected.

Security architecture risk: ⚪ Minimal · up to 96703

The change synchronizes existing metric identifiers without changing credentials, workspace selection, or deployment permissions. No material security risk was identified in the traced path.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The directly traced effect is limited to metric references and dependent computed-attribute payloads in the configured migration destination. The new assignment does not select another workspace, create credentials, or increase the cloud client's authority.

Trust Boundaries and Controls

  • observed — Legacy metadata supplies the mapping key and the existing identifier derivation supplies its value. Computed-attribute construction still requires a supported definition and resolves metric references through the mapping lookup. The PR does not remove these checks or change the deployment client's configuration.

A rabbit checks the metrics’ trail
And finds each cloud ID in the rail
Old names meet new
Mappings hold true
Then hops away, pleased with the tale

I did local test / verification. With these fixes computed attributes are now created on brand new WS from brand new project. Before the fix in this PR metric step did not create any computed attributes. image example of created CA after fix.

Assert the legacy-to-cloud identifier pair.

CloudMetric registers self.meta["identifier"] as the mapping key. The current values-only assertion would also pass if the Cloud ID were stored under the wrong legacy identifier. Assert the expected pair through search_mapping_identifier():

assert (
    ctx.metric_mappings.search_mapping_identifier(
        legacy_metrics[0]["metric"]["meta"]["identifier"]
    )
    == cloud_metric["data"]["id"]
)

the expected cloud metric ID by calling search_mapping_identifier() with
legacy_metrics[0]["metric"]["meta"]["identifier"] and comparing the result with
cloud_metric["data"]["id"], replacing the values-only membership check.

Annotate the new fixture parameter.

metrics_context returns a MetricContext. Add the annotation to satisfy the requirement for comprehensive type hints in new code.
