Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Additional comments not posted (4)
schema.go (1)

684-686: Ensure PrecomputeMessages() is called on custom schemas.

The addition of PrecomputeMessages() ensures that any necessary validation messages are precomputed for custom schemas, aligning with the PR's goal of automating schema validation. This change enhances performance and correctness when dealing with custom schemas.

huma.go (2)

695-703: Precompute schema messages for request bodies.

This block ensures that all schemas in RequestBody.Content have their validation messages precomputed, which aligns with the PR's objective to automate schema validation setup. This change enhances the robustness of schema handling.


707-707: Expanded check for hasInputBody.

The condition now checks that inputBodyIndex has elements, ensuring that the input body is not only defined but also populated. This enhances the control flow and reliability of the function.

huma_test.go (1)

2162-2198: New test for custom schema error handling.

The TestCustomSchemaErrors function verifies that schema validation errors are correctly reported without manual calls to PrecomputeMessages(). This test is crucial for ensuring the robustness of the automated schema validation enhancements introduced in this PR.
