Rails 5 Action Mailer - 大虾PDF参数个数错误

Question

我在我的rails应用程序中设置了大虾生成：

   format.pdf do
             pdf = SalesByDayPdf.new(@daily_salesnp, @amount_total, @discount_total, @grand_total)
             pdf.render_file "daily_sales.pdf"
             send_data pdf.render, filename: 'daily_sales.pdf', type: 'application/pdf', disposition: 'inline'

        end

这是我的 SalesByDayPdf

def initialize(daily_salesnp, grand_total, discount_total, amount_total)
    super()
    @daily_salesnp = daily_salesnp
    @amount_total = amount_total
    @discount_total = discount_total
    @grand_total = grand_total

    header
    text_content
    table_content
    footer
  end

这很好用。

现在我想从 action mailer 发送这个 pdf。我在 DailySalesMailer 中将其设置为：

def send_daily_sale(daily_salesnp, grand_total, discount_total, amount_total)
    @daily_salesnp = daily_salesnp
    @amount_total = amount_total
    @discount_total = discount_total
    @grand_total = grand_total

   attachments["daily_sales.pdf"] = SalesByDayPdf.new(daily_salesnp, grand_total, discount_total, amount_total)
   mail(:to => "email@gmail.com", :subject => 'Sales by Day Report')

end

所以基本上我在邮件程序中复制了 pdf 生成器并传递了在我的控制器中定义的相同参数。

但我得到：

wrong number of arguments (given 1, expected 4)

我做错了什么？

Answer 1

解决办法是修改附件为：

attachments["daily_sales.pdf"] = SalesByDayPdf.new(daily_salesnp, grand_total, discount_total, amount_total).render
