网络::SMTPSyntaxError

Question

我正在使用 rails3.0.6 和 ruby​​ 1.8.7，我可以轻松地从我的应用程序开发模式发送电子邮件。但昨晚我尝试向我的客户电子邮件发送邮件时看到一个新错误，该邮件与我的多态相关联发票模型。错误是：

Net::SMTPSyntaxError in InvoicesController#email_invoice 
501 < @invoice.account.accountable.email >: missing or malformed local part

我的 email.rb 文件代码是：

 def send_invoice(invoice)
   email = '@invoice.account.accountable.email'
   mail(:to => email, :from => "support@thenextwave.in", :subject=>"Invoice, check it.") 
 end

在我的invoice controller 中我做到了：

def email_invoice
  @company = Company.find(User.find(session[:current_user_id]))
  @invoice = Invoice.find(params[:id])
  @invoice_line_items = @invoice.invoice_line_items
  @receipt_vouchers = @invoice.receipt_vouchers
  #email = @invoice.account.accountable.email
  Email.send_invoice(@invoice).deliver
  redirect_to invoice_path(@invoice)
  flash[:success] = 'Email has been sent successfully.'
end

我检查了这个错误，发现它是由于错误的电子邮件地址或错误的 SMTP 设置引起的，但我的 SMTP 设置没问题，因为我可以从我的应用程序发送电子邮件，但下面的行有问题：

@invoice.account.accountable.email

任何帮助都会非常感谢..

Answer 1

我想出了一个解决方案，我在邮件中的email.rb 文件中出错了：

def send_invoice(invoice)
  email = '@invoice.account.accountable.email'
  mail(:to => email, :from => "support@thenextwave.in", :subject=>"Invoice, check it.") 
end

应该是：

def send_invoice(invoice)
  email = invoice.account.accountable.email 
  mail(:to => email, :from => "support@thenextwave.in", :subject=>"Invoice, check it.") 
end

现在我可以轻松发送电子邮件了..
