在django发送每个请求的邮件 [英] Send mail per request in django

问题描述

这真的是杀了我。我一直在处理这个日子。

当用户从我的django网络应用程序下载文件时，我想通过发送邮件通知上传者他的文件已被下载。问题是，如果我下载一个低文件大小（489kb），它将向上传者发送一条邮件。但是如果我下载一个3MB或以上的文件大小，它将向上传者发送 c $ c>多个邮件 / p>



我只是希望每次下载向上传者发送一封邮件通知。

视图：

  @login_required 
 def document_view请求，emov_id）：
 fileload = Emov.objects.get（id = emov_id）
 filename = fileload.mov_file.name.split（'/'）[ -  1] 
 filesize = fileload .mov_file.size 
 response = HttpResponse（fileload.mov_file，content_type =''）
 response ['Content-Disposition'] ='attachment; filename =％s'％filename 
 response ['Content-Length'] = filesize 
 send_mail（'你的文件刚刚被下载'，loader.get_template（'download.txt'）。render （{'fileload'：fileload}）），'[e-mail]'，[fileload.email，]）
返回响应
  

download.txt

 '您的文件{{fileload.name}}已被下载！
  

如何根据下载请求发送邮件？

解决方案

我会建议不同的方法...

当有人下载​​文件时，事件到您的数据库上的表。

写入会话ID，文件名，用户名。

确保session_id + file_name + user_name 唯一键

这样，您可以获得更多可以帮助您的信息。

稍后（作为crontab批处理或保存监听器）发送电子邮件。

您甚至可以发送每日/每周报告等...

This is really killing me. I've been dealing with this for days.

When a user download a file from my django web app, I want to notify the uploader that his file has been downloaded by sending a mail. The problem is, If I should download a low file size (489kb), it will send a mail once to the uploader. But if I should download a file size of 3mb or above it will send more than one mail to the uploader.

I just want it to send one mail notification to the uploader per download.

views:

@login_required
def document_view(request,emov_id):
    fileload = Emov.objects.get(id=emov_id)
    filename = fileload.mov_file.name.split('/')[-1]
    filesize=fileload.mov_file.size
    response = HttpResponse(fileload.mov_file, content_type='') 
    response['Content-Disposition'] = 'attachment; filename=%s' % filename
    response['Content-Length'] = filesize    
    send_mail('Your file has just been downloaded',loader.get_template('download.txt').render(Context({'fileload':fileload})),'[e-mail]',[fileload.email,])
    return response

download.txt

'Your file {{ fileload.name}} have been downloaded!'

How can I send mail per download request?

解决方案

I would suggest a different approach...

When someone download the file, log the event to a table on your database.
Write the Session ID, the file name, the user name.
Make sure that session_id+file_name+user_name are unique key
This way, you can get much more information that can help you later.

Later on (as a crontab batch, or save listener) send the emails.
You can even send a daily/weekly report and so on...
