Walkthrough

Added Jackson annotations to the User model to control JSON serialization behavior. The bookings field is now annotated with @JsonIgnore to exclude it from JSON serialization responses.

Poem

🐰 A rabbit's note on JSON tunes,
The bookings now stay in the shadows—
No more shall they be exposed to light,
When User data travels through the night.
Simple annotations, yet profound! ✨

Tip

📝 Customizable high-level summaries are now available in beta!

You can now customize how CodeRabbit generates the high-level summary in your pull requests — including its content, structure, tone, and formatting.

• Provide your own instructions using the high_level_summary_instructions setting.
• Format the summary however you like (bullet lists, tables, multi-section layouts, contributor stats, etc.).
• Use high_level_summary_in_walkthrough to move the summary from the description to the walkthrough section.

Example instruction:

"Divide the high-level summary into five sections:

1. 📝 Description — Summarize the main change in 50–60 words, explaining what was done.
2. 📓 References — List relevant issues, discussions, documentation, or related PRs.
3. 📦 Dependencies & Requirements — Mention any new/updated dependencies, environment variable changes, or configuration updates.
4. 📊 Contributor Summary — Include a Markdown table showing contributions:
   | Contributor | Lines Added | Lines Removed | Files Changed |
5. ✔️ Additional Notes — Add any extra reviewer context.
   Keep each section concise (under 200 words) and use bullet or numbered lists for clarity."

Note: This feature is currently in beta for Pro-tier users, and pricing will be announced later.

47-49: @JsonIgnore fixes recursion but globally hides bookings from User JSON

Annotating bookings with @JsonIgnore is a straightforward way to prevent the circular reference and should resolve the serialization recursion you described. The tradeoff is that User JSON will now never include bookings, even on endpoints where it might be useful.

If you later need bookings in some responses, consider:

• Using DTOs for user payloads, or
• Using Jackson features like @JsonManagedReference/@JsonBackReference or @JsonIdentityInfo to break the cycle more selectively.

For this PR’s stated goal (eliminate circular reference), the change looks good.

4-5: Imports align with new serialization behavior

Adding the Jackson imports here is consistent with the new @JsonIgnore usage on bookings and keeps concerns localized to the model. No issues from a correctness standpoint.

I know from first line it looks okay to merge this but I wonder is it possible to change the architecture to not to give jsonignore, I am thinking maybe there is a better approach thats why I am asking.

[xkotami]

I was wondering the same as well. I'm currently looking up ways around this because using @jsonignore can hinder future functionality
