Hey Philip, Thanks a lot! Based on your comment, I reread the AssetTagHelper and found a nice(r) solution:
I put the following in development.rb: ENV['HOST'] = 'http://localhost:3000' # images in emails have to have absolute urls ActionController::Base.asset_host = Proc.new do |source| if source.starts_with?('/images/email/') ENV['HOST'] else "" end end And then it works: >> ActionView::Base.new.image_tag('/images/email/header.gif') => "<img alt=\"Header\" src=\"http://localhost:3000/images/email/ header.gif?1234982332\" />" >> ActionView::Base.new.image_tag('/images/project/header.gif') => "<img alt=\"Header\" src=\"/images/project/header.gif\" />" Although I am not sure this is more robust thatn my prev. solution since the host has to be set explicitly. Anyway, thank you, Balint On Feb 19, 6:10 pm, Philip Hallstrom <[email protected]> wrote: > > I am sending out html emails.
