Just to add: This will not work with delayed jobs as request will be empty, so one probably need to use root_url instead of request.host

just another version for simple image_url (works in email-templates too)

def image_url(source)
“#{root_url}#{image_path(source)}”
end

Just what I was looking for. (Though I don’t understand why it’s not baked into Rails.)

Thanks!

Could you help me please? I cannot use this in email layout, somehow…

in application_helper.rb I have
def image_url(source)
   abs_path = image_path(source)
   unless abs_path =~ /^http/
     abs_path = “#{request.protocol}#{request.host_with_port}#{abs_path}”
   end
   abs_path
end
and in my email model (order_mailer.rb) I have
class OrderMailer < ActionMailer::Base
layout 'emails'
. . .
end

but when I use I get
undefined method `image_url’ for #

This doesn’t work either:

class OrderMailer < ActionMailer::Base
include ApplicationHelper
layout 'emails'
. . .
end

@joserwan I know about image_path. It is even used in the code! The problem is that image_path does not always create a full URL.
