Overview

Story 9.4 (D3) — per-request execution context injected into a Query subclass by the internal query dispatch controller. A fresh instance is built per request (NFR8) wrapping the DISPATCHING controller instance; because that controller inherits ‘Ruact.config.query_parent_controller`, every delegated reader resolves to the host’s own machinery — ‘current_user` IS the host’s method (Devise / Pundit / hand-rolled), not a gem-side resolver lambda.

Mirrors the SHAPE of the Story-8.3 ‘StandaloneContext` (plain accessors, per-request instance) while sourcing everything from the controller —the resolver-lambda pattern is superseded by the 2026-06-02 ADR addendum (Decision 2).

Constructor Details

#initialize(controller:) ⇒ QueryContext

Returns a new instance of QueryContext.

Parameters:

  • controller (ActionController::Base) —

    the dispatching controller instance (a generated subclass of ‘Ruact.config.query_parent_controller`).

end

Instance Method Details

#current_user ⇒ Object?

The host’s authenticated user. Resolved through the controller’s own ‘current_user` — public OR private (hand-rolled apps commonly define it `private`). When the host chain defines no `current_user` at all, raises a NoMethodError that names the fix instead of a bare “undefined method” from deep inside a query body.

Returns:

  • (Object, nil)

Raises:

  • (NoMethodError) —

    when the parent controller chain defines no ‘current_user`.
