Overview

Update: 2015-03-26

  • Extracted ConcentricPolicy from Kojac

  • Concentric is now a way of creating Pundit policies based on ConcentricPolicy. It allows shorthand ring security for

simple scenarios, then allow_filter for refinement and arbitrary complex logic to be implemented

  • Concentric works on the simple idea that there are 4 basic abilities: read, write, create and delete.

  • Read and write apply primarily to fields; create and delete apply to records.

  • Creating a record requires the ability to create the record, then normally you require the ability to write some fields.

  • In order to read a record, you need the ability to read at least one field

  • In order to write to a record, you need the ability to write at least one field

  • In order to delete a record, you need the ability to delete the record

  • With Concentric you first use the ring and

implement Pundit Policy classes and methods (eg. update? show?) by querying these 4 abilities
