Overview

Responsible for determining if a user has access to a model based on a configuration file.

Example

Based on the following configuration file in YAML format (e.g. config/permissions.yml):

super_admin:
  User
  Patient
admin:
  Admission
  DrugType

We can determine who has access to what models:

configuration = PolicyConfiguration.new(Patient)
configuration.has_privilege?(user) # => true

configuration.has_privilege?(admin_user) # => false

We can also determine if a model is restricted?

configuration = PolicyConfiguration.new(Patient)
configuration.restricted? # => true

configuration = PolicyConfiguration.new(Drug)
configuration.restricted? # => false
