Force SpinaCMS admin panel to not inject the host:port into the urls

spina_embedded_image_tag_helper.rb

# SpinaCMS will inject image URLs into the Trix content with the host:port as part of the URL
# This makes it hard to port that DB content to another host (say move from localhost to a production or staging site)
# load this patch from the config/application.rb like so:https://guides.rubyonrails.org/engines.html#overriding-models-and-controllers

Spina::ImagesHelper.class_eval do
  def embedded_image_url(image)
    return "" if image.nil?
    main_app.polymorphic_path(image.variant(resize: Spina.config.embedded_image_size), only_path: true)
  end
end
