У меня есть приложение на Rails 6, которое содержит множество веб-сайтов и поэтому должно работать с несколькими доменами в производственном процессе.
<%= f.file_field :media, direct_upload: true %>
Когда я использую указанное выше поле файла с direct_upload: true в производственном процессе, я получаю:
ActionView::Template::Error: Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
Все операции ActionView / ActionText работают без проблем в разработке, но когда я публикую в производство (Heroku), «host» становится неопределенным и выдает исключение всякий раз, когда вызывается маршрут ActiveStorage, такой как rails_direct_uploads_url.
В процессе разработки rails_direct_uploads_url генерирует ожидаемый URL с текущим хостом (myapp.test), не требуя каких-либо дополнительных определений хоста.В производственной среде хост должен быть равен нулю, так как генерируется исключение.
Если я определяю хост по умолчанию в Маршрутах, он захватывает это, но затем возникает несоответствие хоста - он использует хост по умолчанию, а не текущий хости портит кучу вещей.

Я искал похожие проблемы и уже добавил в ApplicationController следующее, и он ничего не исправил:
class ApplicationController < ActionController::Base
def default_url_options(options = {})
{ host: request.host }
end
before_action do
ActiveStorage::Current.host = request.base_url
end
end
Как указать хост при каждом запросе ИЛИ предоставить егоfile_field, rich_text_area и т. д., чтобы он не генерировал упомянутое исключение?
