Treating filtering when parameter correspond to an integer type information on table (admin page requisition)

Overwriting SessionsController from devise_token_auth gem to treat blocking and banishing mechanisms in the user session.

Adding "state", "suspended at" and "reactivated_at" columns to User to allow blocking and banishing mechanisms of users.

Modifying complaint_reason table, setting a new column "status" to define its state (active or inactive), as well as giving it a controller to allow users that has "editor" or  "administrator" as role to create and update its entries

Complaints can now be geted individually identified by the id code (show) and only editors and administrators can see the complaints.
