针对网页浏览器和手机，我们的Email的content_type分别为"text/html"和"text/plain"
我们可以这样做ruby script\generate mailer Notifier multipart_alternative
app/models/notifier.rb:
def multipart_alternative(recipient, name, sent_at = Time.now) subject "Test multipart HTML email" recipients recipient from 'Old Dog <olddog@examplel.com>' sent_on sent_at content_type "multipart/alternative" part :content_type => "text/html", :body => render_message("multipart_alternative", :name => name) part :content_type => "text/plain", :body => render_message("multipart_alternative_plain", :name => name)end
我们的两套模板:
1，app/views/notifier/multipart_alternative_plain.rhtml
Hi <%= @name %>!This is a plain-text message. Enjoy!
2，app/views/notifier/multipart_alternative.rhtml
<html> <body> <h1>Hi <%= @name %></h1> This is a rich-text message. Enjoy! </body></html>
甚至我们可以简化它们:
app/models/notifier.rb:
def implicit_multipart(recipient, name, sent_at = Time.now) subject "Something for everyone." recipients recipient from 'barnam@chadfowler.com' sent_on sent_at body(:name => name)end
然后我们通过给app/views/notifier目录下不同的模板名来做content_type区分，如:
implicit_multipart.text.plain.rhtml和implicit_multipart.text.html.rhtml
这样我们就可以隐式的发送针对不同客户端的Email了
