Warning

Review limit reached

@Alejandroq12, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 13 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Task form validation now reports separate messages for missing or invalid fields. Position zero is valid. Both submit buttons are disabled only during pending submission. Validation messages render as a list.

Changes

Task form validation

Layer / File(s)	Summary
Validation and submission feedback src/features/tasks/TaskForm.tsx	Validation checks title, estimate, due date, and position separately. Position zero is accepted. Both submit buttons are disabled only while submission is pending. Validation messages render as separate list items, while server errors remain available for valid forms.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 839bd

The form now enables creation and improves validation messages, but the position field still presents conflicting rules for fractional values, which may reject or discourage supported entries. This is a bounded correctness/UI consistency risk requiring owner awareness or follow-up.

@claude open an issue because when I try to update a task with a position that has a decimal number I cannot do it. I am investigating and the cause is the schema advertises Float while the query underneath only accepts whole numbers. The declaration lies.

Add a note to report back to the backend dev from my team about it. With the title "The schema declaration does not match the server's actual behavior".

Summary

I looked into this, but I'm not able to open a GitHub issue directly — I don't have a tool for creating issues in this environment (only PR-comment tools are available to me here, and gh CLI calls are blocked/require approval that isn't available in this headless context).

• Investigate the schema vs. query mismatch for the position field
• Attempt to open a GitHub issue — blocked, no issue-creation tool available
• Report back with a summary

What I found in this repo

task-flow is the frontend client — there's no GraphQL schema (*.graphql/*.graphqls) or database/query layer (e.g. schema.prisma) checked into this repo, so I can't directly confirm the backend resolver behavior you described. But the frontend evidence is consistent with your diagnosis:

• src/graphql/generated/graphql.ts types position as number (i.e. the schema advertises it as a Float-like type, not an int).
• src/features/tasks/EditTaskModal.tsx:54 sends position: Number(values.position) straight through with no client-side rounding/truncation.
• src/features/tasks/TaskForm.tsx:104-105 (positionValid) only checks Number.isFinite(positionNumber) && positionNumber >= 0 — it does not require an integer, so the client itself is happy to submit a decimal like 0.5.

That lines up with your finding: the client and schema both treat position as a float, but the underlying query/resolver on the server apparently coerces or rejects non-integer values — i.e. the schema's declared type doesn't match the server's actual behavior.

Suggested issue (please open manually, or let me know if you'd like me to try again with different permissions)

Title: The schema declaration does not match the server's actual behavior

Body:

The GraphQL schema declares Task.position as a Float, and the frontend (task-flow) relies on that contract — e.g. TaskForm/EditTaskModal allow submitting decimal position values like 0.5.

However, when updating a task with a decimal position, the update does not take effect / is rejected. Investigation points to the underlying query on the server only accepting whole numbers, despite the schema advertising Float.

Ask: backend team to either (a) make the query/column actually support fractional values to match the declared Float type, or (b) change the schema to Int and coordinate a client-side update — whichever is intended long-term for task ordering precision.

Reported by @Alejandroq12 via task-flow PR #47.

Feel free to paste this into a new issue on the backend repo (or here) — happy to help further once I know where that repo lives, or if issue-creation permissions get added to my toolset.
