📝 Walkthrough

Summary by CodeRabbit

  • New Features

    • Introduced API support for creating and updating graph templates within a namespace.
    • Added new data models for graph templates and nodes, including validation status and error reporting.
    • Implemented a new endpoint for upserting graph templates.
  • Refactor

    • Updated API route structure for improved clarity and organization.
  • Chores

    • Expanded database initialization to include graph template models.

Walkthrough

This change introduces several new Pydantic models and an enumeration to represent graph templates and their validation status. It adds an async controller function to upsert graph templates, updating or creating them with validation status handling. The API routing prefix and paths were adjusted, and a new authenticated PUT endpoint for graph template upsertion was added. A unique MongoDB index is specified for graph templates.

Poem

In the warren where data flows free,
New templates for graphs now hop with glee.
Nodes and their links, validation in tow,
Enum statuses tell us how things go.
With Pydantic precision, our models take flight—
A bunny’s delight, coding through the night! 🐇✨

1-11: LGTM with minor fixes needed!

The NodeTemplate model structure is well-designed with appropriate type annotations and field descriptions. Once the spelling error is fixed, this will serve as a solid foundation for the graph template system.

state-manager/app/models/graph_template_validation_status.py (1)

5-8: LGTM! Well-defined validation status flow.

The validation statuses provide a clear state machine: PENDING → ONGOING → VALID/INVALID. This covers the complete validation lifecycle appropriately.

state-manager/app/models/db/graph_template_model.py (2)

16-23: Excellent use of unique compound index.

The unique index on (name, namespace) combination prevents duplicate graph templates within the same namespace while allowing the same name across different namespaces. This is a solid design choice for multi-tenant scenarios.


9-14: LGTM! Well-structured database model.

The GraphTemplate model properly inherits from BaseDatabaseModel and includes all necessary fields for graph template management with validation tracking. The field types and descriptions are appropriate.

6-6: Field naming inconsistency remains unaddressed.

Based on past review feedback, other models in the codebase use node_name instead of name for node identification. This inconsistency should be resolved for better maintainability.

Apply this diff to maintain consistency:

-    name: str = Field(..., description="Name of the node")
+    node_name: str = Field(..., description="Name of the node")

1-2: LGTM!

The imports are appropriate for a Pydantic model with proper typing support.


8-8: Spelling error has been correctly fixed.

The previous spelling error "indentifier" has been properly corrected to "identifier".

4-8: LGTM! Enum follows established patterns.

The implementation correctly inherits from (str, Enum) as suggested in previous reviews, ensuring consistency with existing enums like StateStatusEnum and providing proper string serialization support. The validation status values are well-defined and appropriate for tracking graph template validation states.

state-manager/app/routes.py (2)

28-28: LGTM! Router prefix change improves API organization.

The change from a states-specific prefix to a more general namespace prefix allows for better organization of different resource types under the same namespace. The existing state endpoints correctly maintain their paths by adding "/states".


113-122: LGTM! Endpoint follows established patterns.

The new graph template upsert endpoint correctly follows the established patterns for API key validation, request ID handling, and error responses. The authentication flow and logging are consistent with existing endpoints.
