Question 1

How to handle database migrations with Rustorm?

Accepted Answer

Rustorm does not include built-in migration tools. You'll need to use external libraries like `refinery` or manage migrations manually with SQL scripts, as Rustorm focuses on query execution and type mapping rather than schema management.

Question 2

Rustorm vs Diesel: which one is better for raw SQL?

Accepted Answer

Rustorm is better if you prefer writing raw SQL directly and need minimal abstraction with type-safe mapping. Diesel offers a fluent query builder and more features, but Rustorm gives you more control over SQL with less overhead.

Question 3

How to perform complex joins in Rustorm?

Accepted Answer

You can write raw SQL queries with JOIN clauses and use derive macros like FromDao to map the results to Rust structs. Ensure your struct fields match the query columns, and handle nested data manually since Rustorm doesn't automate relationship mapping.

Question 4

Does Rustorm support transactions?

Accepted Answer

Yes, Rustorm supports transactions through its EntityManager (em). You can use methods provided by the Pool and em to manage transactional operations, ensuring data consistency for inserts, updates, and deletes.

Question 5

What databases does Rustorm support?

Accepted Answer

Rustorm supports PostgreSQL, SQLite, and MySQL via feature flags in Cargo.toml. You need to enable features like 'with-postgres' or 'with-sqlite', and note that MySQL has API differences as mentioned in the documentation.

Question 6

How to map nested structs or one-to-many relationships?

Accepted Answer

Rustorm's derive macros handle flat structs well, but for nested relationships, you may need to write custom SQL queries and map results manually using multiple queries or composite structs, as it lacks built-in relationship management.
