在django发送带有附件的电子邮件 [英] Sending emails with attachment in django

问题描述

我正在尝试发送附有django的一些图像的电子邮件。使用的代码是此代码段： http://www.djangosnippets.org/snippets/1063/。 Dunno为什么附件部分给我一个核心错误。

代码。 form.py

 从django导入表单
从通用导入slugify_unique 
从django.conf导入设置$来自django.core.cache的缓存
从django.contrib.admin导入小部件
从django.shortcuts导入get_object_or_404 
 
类WorkForm（forms.Form）：
 name = forms.CharField（label ='Name and surname'，max_length = 64，required = True）
 nick = forms.CharField（label ='nickname'，max_length = 40，required = True）
 email = forms.EmailField（label ='e-mail'，required = True）
 image1 = forms.Field（label ='sample photo'，widget = forms.FileInput，required = True）
 image2 = forms.Field（label ='sample photo'，widget = forms.FileInput，required = True）
 image3 = forms.Field（label ='sample photo'，widget = forms.FileInput，required = True）
 text = forms.CharField（label ='关于你的几句话'，widget = forms.Textarea， required = False）
  

views.py

 从表单导入WorkForm 
从django.core.mail导入send_mail，EmailMessage 
 
 
 def工作（请求）：
 template ='other / work.html'
 
如果request.method =='POST'：
 form = WorkForm（request.POST，request.FILES）
如果表单。 is_valid（）：
 name = form.cleaned_data ['name'] 
 nick = form.cleaned_data ['nick'] 
 email = form.cleaned_data ['email'] 
 subject ='Work'
 text = form.cleaned_data ['text'] 
 image1 = request.FILES ['image1'] 
 image2 = request.FILES ['image2'] 
 image3 = request.FILES ['image3'] 
 try：
 mail = EmailMessage（subject，text，['EMAIL_ADDRESS']，[email]）
 mail.attach（image1.name ，附上.read（），attach.content_type）
 mail.attach（image2.name，attach.read（），attach.content_type）
 mail.attach（image3.name，attach.read（），attach 
 mail.send（）
 template ='other / mail_sent.html'
除了：
返回附件错误
返回render_to_response（template，{ 'form'：form}，
 context_instance = RequestContext（request））
 else：
 form = WorkForm（）
 return render_to_response（template，{'form'：form} 
 context_instance = RequestContext（request））

我做错了什么？

解决案例

您发布的错误追踪与实际代码似乎没有任何关系 - 它似乎是中间件的某种问题（大概在渲染500个错误页面时）。 / p>

但是，您的错误可能是由于使用未定义的变量名称 attach 在调用 mail.attach 。您没有附加变量 - 您已经调用了发布的文件 image1 等，所以你应该使用

  mail.attach（image1.name，image1.read（），image1.content_type）
邮件。 attach（image2.name，image2.read（），image2.content_type）
 mail.attach（image3.name，image3.read（），image3.content_type）

I'm trying to send email with some images attached in django. Code used is this snippet : http://www.djangosnippets.org/snippets/1063/. Dunno why the attachment part returns me a core error.

THe code. forms.py
from django import forms
from common import slugify_unique
from django.conf import settings
from django.core.cache import cache
from django.contrib.admin import widgets    
from django.shortcuts import get_object_or_404                                   

class WorkForm(forms.Form):
    name = forms.CharField(label='Name and surname', max_length=64, required = True )
    nick = forms.CharField(label='nickname', max_length=40, required = True )
    email = forms.EmailField(label='e-mail', required = True )
    image1 = forms.Field(label='sample photo', widget = forms.FileInput,    required = True )
    image2 = forms.Field(label='sample photo', widget = forms.FileInput, required = True )
    image3 = forms.Field(label='sample photo', widget = forms.FileInput, required = True )
    text = forms.CharField(label='Few words about you', widget=forms.Textarea, required = False )
views.py
from forms import WorkForm
from django.core.mail import send_mail, EmailMessage


def work(request):
    template = 'other/work.html'                             

    if request.method == 'POST':
        form = WorkForm(request.POST, request.FILES)
        if form.is_valid():
            name = form.cleaned_data['name']
            nick = form.cleaned_data['nick']
            email = form.cleaned_data['email']
            subject = 'Work'
            text = form.cleaned_data['text']
            image1 = request.FILES['image1']
            image2 = request.FILES['image2']
            image3 = request.FILES['image3']
            try:
                mail = EmailMessage(subject, text, ['EMAIL_ADDRESS'], [email])
                mail.attach(image1.name, attach.read(), attach.content_type)
                mail.attach(image2.name, attach.read(), attach.content_type)
                mail.attach(image3.name, attach.read(), attach.content_type)
                mail.send()
                template = 'other/mail_sent.html'
            except:
                return "Attachment error"
            return render_to_response(template, {'form':form},
                              context_instance=RequestContext(request))   
    else:
        form = WorkForm()                              
    return render_to_response(template, {'form':form},
                  context_instance=RequestContext(request))

What am I doing wrong ?
解决方案
The error traceback you've posted doesn't seem to have anything to do with the actual code - it seems to be some sort of problem with middleware (presumably when rendering the 500 error page).

However, your error is probably caused by your use of the undefined variable name attach in the calls to mail.attach. You don't have an attach variable - you've called the posted files image1 etc, so you should use those names.
mail.attach(image1.name, image1.read(), image1.content_type)
mail.attach(image2.name, image2.read(), image2.content_type)
mail.attach(image3.name, image3.read(), image3.content_type)
