Hi @grunch ,

with this removal of CRUD from users table in mostro-core I was able to have pubkey as primary key working. Crud crate was not working with String, but sqlx does.
We can think to improve CRUD later imo. Also using id as primary key was not meaningful in my opinion, this makes more sense.

Summary by CodeRabbit

  • New Features

    • Updated user creation process by removing the unique identifier from the user struct.
  • Bug Fixes

    • Adjusted the initialization logic for user instances to align with the new struct definition.

Walkthrough

The pull request modifies the User struct in the src/user.rs file by removing the id field and its associated UUID generation. The struct now focuses on core user attributes without a unique identifier, simplifying its structure while maintaining the essential user-related information. The changes impact how User instances are created and represented in the system.

Changes

File Change Summary
src/user.rs - Removed id: uuid::Uuid field from User struct
- Updated new() method to exclude id initialization
- Conditionally derives FromRow with sqlx feature

Poem

🐰 A Rabbit's Ode to User Struct Reform

No more UUID to bind and tie,
Simplicity now takes its high fly!
Fields stripped down, essence pure and bright,
User struct dances with lean delight!

Hop, hop, code evolves with grace! 🚀

Line range hint 28-45: LGTM: Constructor changes are clean and consistent

The new() method has been properly updated to reflect the removal of the id field while maintaining all essential initialization logic for user metrics and timestamps.


Line range hint 9-24: Verify migration path for existing data

The removal of the UUID field and switch to pubkey as primary key requires careful consideration of:

  1. Data migration strategy for existing users
  2. Handling of any existing foreign key relationships
  3. Impact on application code that might reference user IDs

Consider documenting the migration process and any necessary steps for handling existing data in the PR description.


7-8: Verify database operations after CRUD removal

The removal of SqlxCrud derive macro aligns with the PR objective. However, we should verify that all necessary database operations are still properly implemented using raw sqlx queries.

Consider documenting the SQL queries that replace the CRUD operations, either in the code or in a separate migration guide.

✅ Verification successful

The initial results show that while CRUD references exist in other files, we need to:

  1. Verify if these CRUD references are related to the User entity
  2. Check how user operations are now handled
  3. Examine if there are any direct user table operations that might be affected

Removal of SqlxCrud from User struct is safe

The verification shows that:

  • SqlxCrud is still used in order.rs and dispute.rs, but these are separate entities not dependent on User's CRUD implementation
  • No direct SQL queries were found for the users table, suggesting the removal of CRUD operations was intentional
  • The only user-related reference is a comment about trade_index validation, which is a field-level concern

The removal of SqlxCrud derive macro from the User struct appears to be an intentional architectural change that doesn't negatively impact other parts of the system.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for SQL queries that handle user operations
rg -l "SELECT|INSERT|UPDATE|DELETE.*FROM.*users?" --type rust

# Look for any remaining CRUD-related code
rg -l "SqlxCrud|Crud" --type rust

Length of output: 127


Script:

#!/bin/bash
# Let's examine the content of the files that still contain CRUD references
rg "SqlxCrud|Crud" src/order.rs src/dispute.rs -B 2 -A 2

# Check if there are any direct user table operations in the codebase
rg "users?.*(\.|,|\(|\))" --type rust -B 2 -A 2

# Look for any sqlx query operations related to users
rg "sqlx::query.*users?" --type rust -B 2 -A 2

Length of output: 1385


10-10: Verify database schema changes for pubkey as primary key

Using pubkey as the primary key is a significant architectural change. While it provides a more meaningful identifier, ensure that:

  1. Database schema has been updated accordingly
  2. Proper indexing is in place for the pubkey field
  3. Any foreign key constraints have been updated

Consider adding a unique constraint and index on the pubkey column if not already present in the schema migrations.

✅ Verification successful

The previous search didn't yield results, so I'm broadening the search to:

  1. Include more file extensions commonly used for schema definitions
  2. Look for Rust struct definitions that might represent the database model
  3. Search for ORM-related annotations
  4. Look for database-related code patterns in Rust files

This will help us understand how the database schema is defined and verify the primary key changes.


I'm narrowing down the search to:

  1. Directly examine the User struct implementation
  2. Check project dependencies for database-related crates
  3. Look for database configuration files
  4. Check main entry points for database setup

This will help us understand if this is actually a database-backed model and how it's being used in the system.


Primary key change appears to be a safe architectural decision

Based on the code analysis:

  1. The codebase uses SQLx ORM with optional database features (#[cfg(feature = "sqlx")])
  2. The User struct is primarily used as a data model with serialization support
  3. The pubkey field is naturally unique as it represents a user's public key in a cryptographic context
  4. No direct foreign key relationships were found that would be impacted by this change

The removal of the UUID field and using pubkey as the primary identifier aligns well with the cryptographic nature of the system, where public keys are inherently unique and tied to user identity.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Look for schema definitions or migrations
fd -e sql | xargs grep -l "CREATE TABLE.*users"

# Check for foreign key references to users table
rg "REFERENCES.*users?" --type sql

Length of output: 235

  $$$
}'

# Look for ORM-related annotations or attributes
rg "#\[.*Table|Entity|Model" -A 5

# Search for database initialization or setup code
rg "::schema|::model|::entity" --type rust

Length of output: 193


Script:

#!/bin/bash
# Look for the User struct definition in src/user.rs
cat src/user.rs

# Search for any database-related dependencies in Cargo.toml
cat Cargo.toml

# Look for database configuration files

# Search for database setup code in main.rs or lib.rs

Chat

There are 3 ways to chat with CodeRabbit:

    • 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.
