Send email with attachments action Mailer Ruby on Rails

问题

根据<https://edgeguides.rubyonrails.org/action_mailer_basics.html>，我尝试配置我的应用程序以发送带附件的电子邮件，但出现了错误NameError (undefined local variable or method attachment for #&lt;InvoiceMailer:0x00007fde0d7bfe88&gt; Did you mean? attachments)。

以下是我在我的控制器中的内容：

  1. array_docs.each do |doc| 
  2.     decoded_doc = URI.decode(doc)               
  4.     tmp_file = Tempfile.new(['bill', '.pdf'])
  5.     tmp_file.binmode
  6.     open(decoded_doc, "Authorization" => bearer_token) do |url_file|
  7.        tmp_file.write(url_file.read)
  8.        tmp_file.rewind
  9.        tmp_file.read
  10.        attachment = tmp_file.path
  11.        InvoiceMailer.send_invoice(attachment).deliver
  12.     end
  13. end

以下是我的Invoice Mailer：

  1. class InvoiceMailer < ApplicationMailer
  3. default :from => 'Test <no-reply@test.co>'
  4.  
  5.   def send_invoice(attachment)
  6.     attachments['test-bill'] = File.read(attachment)
  7.     mail(to: "steven@test.com",
  8.     subject: "check if it works")
  9.   end
  10. end

以及我的视图send_invoice.html.erb

  1. <!DOCTYPE html>
  3. <html>
  4.     <head>
  5.         <meta content="text/html; charset=UTF-8" http-equiv="Content-Type" />
  6.     </head>
  7.     <body>
  8.         <h1>Test to check if it works </h1>
  9.         <p>Hello world</p>
  10.     </body>
  11. </html>

添加到我的development.rb并重新启动服务器：

  1. config.action_mailer.delivery_method = :sendmail
  2. config.action_mailer.perform_deliveries = true
  3. config.action_mailer.raise_delivery_errors = true

如何将变量从控制器传递到邮件发送文件中？

英文:

Following <https://edgeguides.rubyonrails.org/action_mailer_basics.html>, I try to configure my app to send email with attachments but I have the error NameError (undefined local variable or method attachment for #&lt;InvoiceMailer:0x00007fde0d7bfe88&gt;
Did you mean? attachments)

Here is what I have in my controller :

  1.         array_docs.each do |doc| 
  2.             decoded_doc = URI.decode(doc)               
  3.             
  4.             tmp_file = Tempfile.new([&#39;bill&#39;, &#39;.pdf&#39;])
  5.             tmp_file.binmode
  6.             open(decoded_doc, &quot;Authorization&quot; =&gt; bearer_token) do |url_file|
  7.                tmp_file.write(url_file.read)
  8.                tmp_file.rewind
  9.                tmp_file.read
  10.                attachment = tmp_file.path
  11.                InvoiceMailer.send_invoice.deliver
  12.             end
  13.         end

Here is my Invoice Mailer :

  1. class InvoiceMailer &lt; ApplicationMailer
  3. default :from =&gt; &#39;Test &lt;no-reply@test.co&gt;&#39;
  4.  
  5.   def send_invoice
  6.     attachments[&#39;test-bill&#39;] = File.read(attachment)
  7.     mail(to: &quot;steven@test.com&quot;,
  8.     subject: &quot;check if it works&quot;)
  9.   end
  10. end

And my view send_invoice.html.erb
<!DOCTYPE html>

  1. &lt;html&gt;
  2. &#160;&#160;&lt;head&gt;
  3. &#160;&#160;&#160;&#160;&lt;meta content=&quot;text/html; charset=UTF-8&quot; http-equiv=&quot;Content-Type&quot; /&gt;
  4. &#160;&#160;&lt;/head&gt;
  5. &#160;&#160;&lt;body&gt;
  6. &#160;&#160;&#160;&#160;&lt;h1&gt;Test to check if it works &lt;/h1&gt;
  7.     &lt;p&gt;Hello world&lt;/p&gt;
  8. &#160;&#160;&lt;/body&gt;
  9. &lt;/html&gt;

Added to my development.rb and restart my server :

  1. config.action_mailer.delivery_method = :sendmail
  2. config.action_mailer.perform_deliveries = true
  3. config.action_mailer.raise_delivery_errors = true

How to pass the variable from the controller to the mailer file ?

答案1

得分: 0

  1. # controller
  2. InvoiceMailer.send_invoice(attachment).deliver
  4. # mailer
  5. def send_invoice(attachment)
  6.   attachments['test-bill'] = File.read(attachment)
  7.   ...
  8. end
英文: 
  1. # controller
  2. InvoiceMailer.send_invoice(attachment).deliver
  4. # mailer
  5. def send_invoice(attachment)
  6.   attachments[&#39;test-bill&#39;] = File.read(attachment)
  7.   ...
  8. end
  10. </details>
  14. # 答案2
  15. **得分**: 0
  17. 这对我有效：
  19. 在控制器中：
  21. ```ruby
  22. attached_file = tmp_file.read
  24. attachment = Array.new
  25. attachment = {filename: "nameoffile.something", file: attached_file}
  26. InvoiceMailer.send_invoice(attachment).deliver

邮件类中，您可以通过仅发送attached_file来简化附件，文件名只是灵活的，如果您想要使用其他名称重命名它。

  1. def send_invoice(attachment)
  2.    if attachment.present? 
  3.      attachments[attachment[:filename]] = {content: attachment[:file]}
  4.    end
  5.   ...
  6. end
英文:

this works for me:

in controller

  1. attached_file = tmp_file.read
  3. attachment&#160;= Array.new
  4. attachment = {filename: &quot;nameoffile.something&quot;, file: attached_file}
  5. InvoiceMailer.send_invoice(attachment).deliver

the mailer class, you can simplify the attachment via sending only the attached_file, the filename is just be flexible if you want to rename it with other names.

  1. def send_invoice(attachment)
  2.    if attachment.present? 
  3.      attachments[attachment[:filename]] = {content: attachment[:file]}
  4.    end
  5.   ...
  6. end
