在Rails 3.0.X中,这一行曾经工作过:
email_banner = File.read(Rails.root.join('public/images/email_banner.png'))
由于Rails3.1RC将images目录移到了app/assets/images中,我得到了错误:
Errno::ENOENT: No such file or directory - /Users/Foo/Sites/foobar/public/images/email_banner.png
我该如何在Rails3.1RC中实现这一点?
供您参考,我的UserMailer类的代码块:
class UserMailer < ActionMailer::Base
default :from => "from@example.com"
def verification_email(user_id)
@user = User.find(user_id)
@verification_url = verification_url(:id => @user.verification_code)
email_banner = File.read(Rails.root.join('public/images/email_banner.png'))
attachments.inline['email_banner.png'] = email_banner
mail(:from => "Foobar <support@foobar.com>",
:to => "#{@user.full_name} <#{@user.email}>",
:subject => 'Foobar Verification Email')
end
....
有我可以使用的资产路径吗?
你有点回答了自己的问题,你只需要改变你调用的路径。
email_banner = File.read(Rails.root.join('app/assets/images/email_banner.png'))
