What are the best practices for Rails models?

Best practices for Rails models include keeping them skinny, using validations, and leveraging scopes for queries.

Can you explain what you mean by keeping models skinny?

Keeping models skinny means that they should focus on business logic and not include too much code. Use service objects for complex logic.

What about validations? How should I implement them?

Implement validations in your models to ensure data integrity. Use built-in validators like validates_presence_of and custom ones when necessary.

Are there any specific patterns I should follow?

Yes, consider using the Active Record pattern, and also look into using concerns for shared functionality across models.
