Send “carrierwave” gem attachments via email Ruby on Rails

Question

I am using Carrierwave gem + Mercury Editor and I want allow users to create mail campaigns and send them. Everything works well, but I have problems with inline images.

In image_uploader.rb I have

def store_dir
  "#{uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end

I have newsletters.contents column, and it includes preformatted HTML from Mercury including images.

So in email .eml file I have path like <img src="uploads/..."> instead of <img src="http://uploads/..."> If I change path to #{Rails.root}/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id} uploading not working at all.

Is there any way to fix this?

Answer 1

I solved it by adding gsub in mercury_update controller action

def mercury_update
    newsletter = Newsletter.find(params[:id])
    newsletter.title = params[:content][:newsletter_title][:value]
    newsletter.content = params[:content][:newsletter_content][:value]
    newsletter.update_attributes(content: newsletter.content.sub!('<img src="/uploads/', '<img src="http://host.com/uploads/'))
    newsletter.save!
    render text: ""
end

But I feel it is ugly solution
