When using Active Record, developers should keep a few important tips in mind:
Keep Queries Simple: Try not to make queries too complicated. If they get tricky, break them into smaller parts.
Use Scopes: Scopes are helpful for common queries. For example:
scope :active, -> { where(active: true) }
This means you can easily find active records.
Eager Loading: To avoid N+1 queries, use includes to load related records all at once:
Post.includes(:comments).where(published: true)
This makes your code quicker and more efficient.
Migrations: Make sure to create and run migrations when you need to change the database's structure. This keeps everything organized.
Validation: It's important to set up model validations. This helps keep your data correct and reliable.
By following these tips, you can keep your code clean, efficient, and running smoothly!
