Module: Envoy::PageSurface

Extended by:
ActiveSupport::Concern
Defined in:
lib/envoy/page_surface.rb

Overview

Declares which surface a page opens a chat against.

class TodayController < ApplicationController
envoy_surface :today, context_key: -> { "day:#{@date.to_fs(:iso8601)}" }
end

The context_key lambda is instance_exec'd in the controller, so instance variables set by the action are in scope. Pages that do not declare a surface get no bubble — opt-in by default.

#envoy_page_surface ⇒ Object

Nil when the controller never declared one — the layout renders nothing.
