end

#newsletter_attachment_url_env ⇒ Object

Rack env (http_host/https) used to resolve Active Storage attachment URLs when rendering a body. Prefers the live request; falls back to the mailer’s default_url_options when rendering an email (no request). Returns {} when neither is available — the host must set default_url_options for emails.

  req = request if respond_to?(:request)
  if req.try(:host).present?
    {http_host: req.host_with_port, https: req.ssl?}
  else
    opts = ::ActionMailer::Base.default_url_options || {}
    return {} if opts[:host].blank?

    host = opts[:port] ? "#{opts[:host]}:#{opts[:port]}" : opts[:host]
    {http_host: host, https: opts[:protocol].to_s == "https"}
  end
end

#newsletter_body(newsletter) ⇒ Object

Renders a newsletter’s rich-text body for display.

Action Text attachments backed by Active Storage render through the host’s active_storage/blobs/_blob partial, which calls ‘image_tag blob.representation(…)`. That resolves the variant into a URL via `polymorphic_url`, which only works against a route set that defines the rails_blob/representation routes — the HOST application’s. During a request Action Text renders content with the current controller’s view context as its renderer; because this engine is ‘isolate_namespace`d that context uses the ENGINE’s route set, where those routes don’t exist, so the render raises “Can’t resolve image into URL: undefined method ‘to_model’”.

Action Text’s own ‘action_controller_renderer` is built on a bare ActionController::Base, whose routes are the application’s. Rendering the body through it makes attachment URLs resolve correctly.

That renderer has no incoming request, so without an explicit host it builds URLs against ActionDispatch’s placeholder host (“example.org”), which breaks the images. We give it the right host per context: the live request’s host on the web, and the mailer’s configured host (default_url_options) in emails — so the show page uses the real host and delivered emails get absolute URLs.

#newsletter_time_options ⇒ Object

Time-of-day options for the schedule dropdown: 8:00 AM to 8:00 PM in 30-minute steps. Returns [label, value] pairs (“8:00 AM” => “08:00”) for options_for_select / f.select; the value is the HH:MM stored as scheduled_time and composed into scheduled_at.
