Module: Doorkeeper::Models::Concerns::WriteToPrimary

Extended by:

ActiveSupport::Concern

Included in:

AccessGrantMixin, AccessTokenMixin, ApplicationMixin

Defined in:

lib/doorkeeper/models/concerns/write_to_primary.rb

Overview

Provides support for Rails read replicas by ensuring write operations use the primary database when automatic role switching is enabled.

When Rails uses automatic role switching with read replicas, GET requests are routed to read-only databases. However, Doorkeeper may need to write to the database during GET requests (e.g., creating access tokens during implicit grant flow). This concern wraps write operations with connected_to(role: :writing) to ensure they use the primary database.

This concern is only active when:

1. ActiveRecord supports connected_to (Rails 6.1+)
2. The configuration option is enabled
