问题描述

我正在尝试发送在 django 中附加了一些图像的电子邮件.使用的代码是这个片段:http://www.djangosnippets.org/snippets/1063/.我不知道，为什么附件部分会返回一个核心错误.

I'm trying to send email with some images attached in django. Code used is this snippet : http://www.djangosnippets.org/snippets/1063/. I don't know, why the attachment part returns me a core error.

代码.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))

推荐答案

您发布的错误回溯似乎与实际代码没有任何关系 - 它似乎是中间件的某种问题(大概是呈现 500 错误页面时).

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).

但是，您的错误可能是由于您在调用 mail.attach 时使用了未定义的变量名称 attach 造成的.您没有 attach 变量 - 您已将发布的文件称为 image1 等，因此您应该使用这些名称.

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)
