Walkthrough

The changes enhance error handling in the user module. In the UserController, several methods now wrap calls to the service in try-catch blocks, capturing errors and throwing a BadRequestException with a specific message. Additionally, an import for BadRequestException is added. In UserService, the error message for a non-active or non-existent poll in getUserVotes was updated to include an exclamation mark.

Changes

File(s)	Summary of Changes
src/user/user.controller.ts	Added try-catch blocks to asynchronous methods (getUserData, getUserActivities, getUserVotes, setVote, editVote) for error handling and added import for BadRequestException.
src/user/user.service.ts	Modified the error message in the getUserVotes method, appending an exclamation mark to the original message.

Poem

I'm a rabbit hopping through the code,
Error handling now lightens the load.
Try-catch guards each useful call,
With messages clear, we stand tall.
Hop on, code friend, let's celebrate it all!

🪧 Tips

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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.
