Instance Method Details

#permit? ⇒ Boolean

In a specific Role based Permit you can use 

def permit? user, options = {}
  ... permission logic follows

This will call the Permit::Base#permit? instance method (the method below) It will only return true if the user matches the role of the Permit class and the

If these confitions are not met, it will return false and thus the outer permit will not run the permission logic to follow

Normally super for #permit? should not be called except for this case, or if subclassing another Permit than Permit::Base

Returns:

  • (Boolean)
