actionmailer推迟了作业错误
我有一个奇怪的错误使用邮件和延迟工作与轨3和红宝石1.9.2。
我在邮件中有一个方法
def new_site_message(sitereq)
@footer = Textvar.where(:title => "email_footer").first
@sitereq = Sitereq.first
mail(:to => EmailGroup.where(:name => "new_sitemessage_group").first.emails.map(&:email).join(", "), :subject => "Test")
end
它工作得很好，延迟工作无延迟。 但是当我延迟它 - 我得到错误（从delayed_jobs表，last_error）：
{undefined method `ascii_only?' for #<Email:0xa67780c>

其他邮件程序方法在延迟作业中正常工作，只有这样才会出错。 我试图改变：以模拟字符串电子邮件，但没有响铃。
我该怎么做才能纠正这个错误？
