What are the best practices for Rails policies?

What are the best practices for implementing policies in a Rails application?

Best practices for Rails policies include using Pundit or CanCanCan for authorization, keeping policies thin, and ensuring they are testable.

Can you explain how to use Pundit for authorization?

Sure! Pundit allows you to define policies for your models. You create a policy class for each model and define methods that correspond to the actions you want to authorize.

What should I consider when writing tests for my policies?

When testing policies, ensure you cover all possible scenarios, including edge cases. Use RSpec or Minitest to write your tests, and check both allowed and denied actions.

Are there any common pitfalls to avoid with Rails policies?

Yes, common pitfalls include overcomplicating policies, not keeping them DRY, and failing to handle unauthorized access gracefully.
