添加附件会破坏邮件内容 rails
Adding an attachment breaks mail content rails
我使用 Rails 4.2 应用程序，我需要将邮件的 PDF 版本附加到邮件本身。我找到了一种渲染视图并将渲染视图转换为 PDF 的方法，但是向邮件添加附件会导致无法发送其内容。
附件发送代码：
def failed_charge(bill)
@monthly_bill = bill
@organization = bill.organization
@edit_account_url = edit_account_url(organization)
I18n.with_locale(organization.locale) do
@date = I18n.l Time.now.utc.to_date, format: :medium
@display_period = [bill.period_start, bill.period_end]
.map { |t| I18n.l(t.to_date, format: :medium).strip }
.join(' – ')
invoice_content = WickedPdf.new.pdf_from_string(
render_to_string(template: 'billing_mailer/failed_charge'),
{
margin: {top: 0, bottom: 0, left: 0, right: 0}
}
)
File.open('invoice.pdf', 'wb') do |file|
file.write invoice_content
end
attachments['invoice.pdf'] = invoice_content
mail(
to: bill.billing_email,
bcc: [INVOICES_EMAIL_FULL, SUPPORT_EMAIL_FULL],
subject: I18n.t('billing_mailer.subject_failed_charge'),
)
end
end
结果邮件：

message.body = to_table(Rinku.auto_link(body))
