What are the best practices for authorization in Rails applications?

Some best practices include using Pundit or CanCanCan for managing permissions, keeping your authorization logic in policies, and ensuring that sensitive actions are protected by proper checks.

How do I implement Pundit in my Rails app?

To implement Pundit, first add it to your Gemfile, then run bundle install. After that, generate the policies using rails generate pundit:install.

Can you explain how to create a policy in Pundit?

Sure! A policy in Pundit is a Ruby class that defines methods for each action you want to authorize. For example, you might have a PostPolicy class with methods like show?, create?, and update?.

What should I do if I need more complex authorization rules?

For complex rules, consider using scopes in your policies or combining multiple policies. You can also create custom methods to handle specific cases.
