Module: Terrazzo::UsesSuperglue::TemplateLookupOverride

Included in:
ApplicationController
Defined in:
lib/terrazzo/uses_superglue.rb

Overview

Prepended to fix a template shadowing problem.

When a controller inherits a long view prefix chain (e.g. from Devise or other engines), Superglue’s _render_template calls template_exists? with all those prefixes and may find a gem-supplied HTML template, causing it to render the unstyled ERB instead of the React page. This override restricts the template existence check to the app’s own view path only.
