What are the differences between Pundit and Cancancan for authorization in Rails?

Can you explain the differences between Pundit and Cancancan for authorization in Rails?

Sure! Pundit is a policy-based authorization library, while Cancancan is a role-based authorization library. Pundit uses plain Ruby classes to define policies, whereas Cancancan uses a more declarative approach with abilities.

Which one is easier to implement for a beginner?

For beginners, Cancancan might be easier to grasp because of its straightforward DSL for defining abilities. Pundit requires a bit more understanding of Ruby classes and policies.

Are there any performance differences between the two?

Generally, both libraries perform well, but Pundit can be more efficient in certain scenarios since it allows for more granular control over authorization logic.

Can I use both in the same project?

Yes, you can use both in the same project, but it's usually better to stick with one to avoid confusion and maintain consistency in your authorization logic.
