My app sends multipart/alternative html (with embedded images) and text emails and lets the client choose.
Here's how I set things up. I take no credit for this - it's a combo of ideas I found while searching for a solution. On the shoulders of giants and all that. I'm running 2.3.2. Install http://code.google.com/p/premailer/ I ended up creating lib/premailer/ and putting the files in there since they need to be edited a little. In premailer.rb, change initialize to take an HTML string instead of a URL. class UserNotify < ActionMailer::Base public def portfolio_data(user,portfolios) # ... set up your subject, target, etc ... content_type "multipart/alternative" part "text/plain" do |p| p.body = render_message('portfolio_data.text.plain.erb',@body) p.transfer_encoding = "base64" # VERY IMPORTANT end @parts << UserNotify.create_portfolio_html_data(@body) end # embed images in the email. # convert HTML with stylesheets to HTML with style attributes def portfolio_html_data(body) content_type "multipart/related" yahoo_cid = Time.now.sec.to_s + "_yahoo" google_cid = Time.now.sec.to_s + "_google" part "text/html" do |p| pm = Premailer.new(render_message ('portfolio_data.text.html.erb',body)) m = pm.to_inline_css pm.warnings.each do |warning| clients = (warning[:clients] && (" (" << warning[:clients] << ")")) || "" RAILS_DEFAULT_LOGGER.warn("Premailer warning: #{warning [:level]}: #{warning[:message]}#{clients}") end # RAILS_DEFAULT_LOGGER.debug("\n\n\nm:\n#{m}\n\n") m.gsub!(/src="#{PortfolioHelper::YAHOO_IMG}[^"]*"/,"src=\"cid:# {yahoo_cid}\"") m.gsub!(/src="#{PortfolioHelper::GOOGLE_IMG}[^"]*"/,"src=\"cid:# {google_cid}\"") p.body = m p.transfer_encoding = "base64" # VERY IMPORTANT end f = File.open("#{RAILS_ROOT}/public# {PortfolioHelper::YAHOO_IMG}","rb") inline_attachment :content_type => "image/gif", :body => f.read, :filename => "yahoo.gif", :cid => "<#{yahoo_cid}>" f.close f = File.open("#{RAILS_ROOT}/public# {PortfolioHelper::GOOGLE_IMG}","rb") inline_attachment :content_type => "image/gif", :body => f.read, :filename => "google.gif", :cid => "<#{google_cid}>" f.close end end portfolio_data.text.html.erb looks roughly like this: <html> <head> <style> <%=File.read("#{RAILS_ROOT}/public/stylesheets/porb.css")-%> </style> </head> ... </html> This works well for me. Images embed, css gets inlined, client gets to choose whether it wants text or html. I ought to do the next step and use the html_to_text stuff in premailer but I already had the text template written. If there's a better way to pull all this stuff together I'm all ears. -Chris --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
