my_courses_controller.rbおよび他のすべてのコントローラのパスは正しく、再確認されています。奇妙なことに、2 番目の要求が来るとすぐに、すべてが機能します。本番環境は今のところ問題ないようです。レールautoload_pathは延長されていません。
構造のコード例:
module DashboardWidgets
class WidgetsController < ::ApplicationController
private
def set_user
# sets user and stuff...
end
end
end
module DashboardWidgets
class MyCoursesController < WidgetsController
include CustomView
layout false
def show
authorize [:dashboard_widgets, :my_course]
set_dashboard_widget
set_user
search = Searches::LmsSearch.new current_user.learning_course_ids_by_type.merge(search_params)
@courses = search.search
render_custom_view
end
