Overview

Preparation

   • git clone git@github.com:varvet/pundit.git

Code Reading

Let's take a look at the authorize method used when applying permissions.

1. authorize

• varvet/pundit/blob/main/lib/pundit.rb#L75
  • Defined as a class method of the module
• varvet/pundit/blob/main/lib/pundit/context.rb#L55
  • The actual processing is done in the authorize method of the Pundit::Context class
  • Here, the policy is checked, and permissions are determined.

The implementation was surprisingly simple.
