Add centralized credential management and enhance graph table operations#44
Conversation
- Introduced a new `.gitignore` file to exclude sensitive credentials and data files. - Refactored credential loading in demo scripts to improve path handling and flexibility. - Updated `01_setup_credentials.py`, `02_create_graph.py`, and other demo scripts to utilize the new credential utilities for better management of graph IDs and data generation. - Enhanced the `save_graph_id` and `get_graph_id` functions to support multiple demo contexts. - Added tests for new credential utilities and ensured existing functionality remains intact.

Review SummaryThis PR makes substantial improvements to credential management and graph table operations. The changes are well-structured with comprehensive test coverage (778 new lines of tests). Overall, this is a solid PR with good architectural decisions, though there are some areas that could be improved. Strengths1. Excellent Credential Management Refactoring
2. Comprehensive Test Coverage
3. Smart Table Type Inference
4. Enhanced Error Handling
Issues & RecommendationsCritical Issues1. Inconsistent Schema Validation Error HandlingLocation: The table service expects a # table_service.py:65
except Exception as e:
logger.error(f"Failed to parse schema DDL for graph {graph_id}: {e}")
raise ValueError(f"Invalid schema DDL: {str(e)}") from eRecommendation: Document the expected exceptions from 2. Empty Schema Validation Logic IssueLocation: robosystems/operations/graph/table_service.py:69-71 if not node_types and not relationship_types:
logger.warning(f"No node or relationship types found in schema for graph {graph_id}")
return []But the test expects a def test_empty_schema_returns_empty_list(self, table_service, mock_session):
schema_ddl = ""
with pytest.raises(ValueError, match="Schema DDL cannot be empty"):
table_service.create_tables_from_schema("kg123", "user123", schema_ddl)Issue: The implementation returns an empty list but the test expects an exception. These need to be aligned. Recommendation: Either:
Major Issues3. Missing Validation for create_entity FlagLocation: robosystems/operations/graph/entity_graph_service.py:262-273 The create_entity = entity_data_dict.get("create_entity", True)Recommendation: Add type validation: create_entity = entity_data_dict.get("create_entity", True)
if not isinstance(create_entity, bool):
raise ValueError(f"create_entity must be a boolean, got {type(create_entity)}")4. Row Count Estimation Fallback May Be InaccurateLocation: robosystems/routers/graphs/tables/upload.py:336-339 except Exception as e:
logger.warning(
f"Could not calculate row count for {graph_file.file_name}: {e}. Row count will be estimated."
)
actual_row_count = actual_file_size // 100Issue: The fallback estimation ( Recommendation: Either:
5. Auto-Table Creation May Cause IssuesLocation: robosystems/routers/graphs/tables/upload.py:66-80 Tables are auto-created on first file upload with empty schema: table = GraphTable.create(
graph_id=graph_id,
table_name=table_name,
table_type=inferred_type,
schema_json={"columns": []}, # Empty schema!
session=db,
)Issue: Auto-created tables have no schema information, which could cause issues during ingestion if the schema doesn't match what's expected. Recommendation: Consider one of:
Minor Issues6. Duplicate Error Message TextLocation: Multiple files (upload.py:52-54, ingest.py:47-49) The shared repositories error message is duplicated across multiple router files. Recommendation: Extract to a constant: # In robosystems/middleware/graph/types.py
SHARED_REPO_ERROR_MESSAGE = (
"Shared repositories are read-only. File uploads and data ingestion are not allowed. "
"Shared repositories provide reference data that cannot be modified."
)7. Missing Type Hints in Credential UtilsLocation: examples/credentials/utils.py Several functions lack complete type hints:
Recommendation: Add complete type hints using 8. Magic Numbers in CodeLocation: Multiple locations Examples:
Recommendation: Extract to named constants: PRESIGNED_URL_EXPIRY_SECONDS = 3600
FALLBACK_BYTES_PER_ROW = 100Code Quality ObservationsPositive

💡 Codex Review
robosystems/robosystems/graph_api/core/duckdb_manager.py
Lines 495 to 499 in 15abe24
Update DuckDB refresh to honor new "uploaded" status
The file upload workflow now sets files to upload_status="uploaded" (see the new FileStatusUpdate route), but the refresh path still filters for upload_status == "completed". After this change, every call to refresh a staging table will throw No completed files found… even when the user has correctly marked files as uploaded, effectively blocking ingestion through the graph API. The status predicate here needs to be updated (or accept both values) to match the rest of the pipeline.
