Feature flags in Rails: How to roll out and manage your features like a pro
This code mounts the Flipper UI at the /flipper endpoint in your application. The RoleConstraint class is used to restrict access to the UI to users who have the manage role. You can customize this constraint to suit your specific needs. In this case, we're using the CanCanCan gem to gate specific routes to admin users. If you haven't worked with CanCanCan before, ignore the RoleConstraint portion.

How would you store roles with up to 64 permissions?

Protect your GraphQL data with resource_policy
Expressing authorization rules can be a bit challenging with the use of other authorization gems, such as pundit or cancancan. The resource_policy gem provides a more concise and expressive policy definition that uses a simple block-based syntax that makes it easy to understand and write authorization rules for each attribute.

Web-app security risks demonstrated
In production code you would most likely use a library for access control, such as CanCanCan

YAGNI exceptions
PS If you do mobile / web work (or something else with "detached" UI), I find that declarative access control rules are far superior to imperative ones, because they can be serialized and shipped over the wire. For example, backend running cancancan can be easily send the same rules to casl on the frontend, while if you used something like pundit to secure your backend, you either end up re-implementing it in the frontend, or sending ton of "canEdit" flags with every record.
