В моем приложении Rails у меня есть задание на создание PDF-файлов с помощью WickedPDF. Это работало нормально, пока я не перешел на Rails 5.2, теперь я получаю эту ошибку:
ActionView::Template::Error (Can't resolve image into URL: undefined method `polymorphic_url' for #<ActionView::Base:0x0000000004854590>):
Код, где это происходит, это строка в представлении:
image_tag(image)
Это представление взято из задания, которое я полностью добавил ниже. Ошибка происходит при выполнении последнего метода в классе: private def render_image_pdf(view, pdf_name, image), где он отображает PDF.
После отката к Rails 5.1 все снова работает нормально, поэтому я почти уверен, что это как-то связано с добавленной / измененной функцией в Rails 5.2. Так что я должен изменить, чтобы это снова заработало?
