如何将'premailer'与Rails集成

Question

如何将' premailer'gem与Rails(3.0.7)项目集成？我目前在我的邮件中:

def welcome(user)
  @user = user

  mail to: user.email, subject: "Welcome"
end

但我无法弄清楚如何整合图书馆.我需要打电话:

premailer = Premailer.new(html)
html = premailer.to_inline_css

但是,我不确定如何从邮件程序操作访问我的电子邮件的内容.

Answer 1

看看我最近写的简单的premailer-rails gem.它使用Rails邮件程序挂钩进行转换.

Answer 2

尝试:

def premailer(message)
  message.text_part.body = Premailer.new(message.text_part.body.to_s, with_html_string: true).to_plain_text
  message.html_part.body = Premailer.new(message.html_part.body.to_s, with_html_string: true).to_inline_css

  return message
end

def welcome(user)
  @user = user

  message = mail to: user.email, subject: "Welcome"
end

Answer 3

对于Rails 4用户,您可以:添加宝石

gem 'premailer-rails'
gem 'nokogiri' (if you don't have it)

将其添加到样式表(Haml):

%style{type:"text/css"}= Rails.application.assets.find_asset('email_stylesheet').to_s

由于某种原因,它无法使用正常的stylesheet_link_tag

这就是我必须做的一切.希望这有帮助!
