我在这段代码中找不到错误。我尝试过隔离问题，但是当我将相关代码复制到单独的文件中时，它可以工作。问题肯定出在周围的代码上，但我不明白它有什么关系。这是一切:
问题出在“激活您的项目帐户”电子邮件上。它向我发送了一封电子邮件，其中包含以下内容:
--===============1413769924==
Content-Type: text/plain; charset="utf-8"
MIME-Version: 1.0
Content-Transfer-Encoding: quoted-printable
text here
--===============1413769924==
Content-Type: text/html; charset="utf-8"
MIME-Version: 1.0
Content-Transfer-Encoding: quoted-printable
text here
对于两个版本的电子邮件，“此处的文本”是相同的，但在实际文件中不是，并且当我尝试发送时不是来自不同脚本的电子邮件。代码如下:
def join_transporter(request):
form = TransporterJoinForm(request.POST)
if request.POST and form.is_valid():
user = User(
username = form.username.val,
first_name = form.first_name.val,
last_name = form.last_name.val,
email = form.email.val,
is_active = False,
)
user.set_password(form.password1.val)
user.save()
Profile.objects.create(
user = user,
phone = form.phone.val,
company_name = form.company_name.val,
details = Transporter.objects.create(),
address = Address.objects.create(
city = form.address.city.val,
province = form.address.province.val,
country = form.address.country.val,
street = form.address.street.val,
postal_code = form.address.postal.val
)
)
e = send_multipart_email('Activate Your PROJECT Account',
'emails/transporter_joined',
{'user':user, 'fee': settings.PROJECT_FEE * Decimal('100.00'),'settings':settings},
[user.email],
send_immediately=False
)
e.attach_file('/home/PROJECT/webapps/media/files/InsuranceLetter.pdf')
e.send() # <------- PROBLEM IS HERE
send_multipart_email('Transporter Joined',
'emails/staff_transporter_joined',
{'trans':user,'settings':settings},
['service@PROJECT.com','EMAIL@gmail.com']
)
messages.info(request, 'Thank you for registering. Please check your email for details on how to activate your account.')
return redirect('home')
def send_multipart_email(subject, template, data_dict, recipient_list, from_email=settings.DEFAULT_FROM_EMAIL, send_immediately=True):
if not isinstance(recipient_list, list): recipient_list = [recipient_list]
d = {'settings':settings} # default context vars
d.update(data_dict)
c = Context(d)
try:
tt = loader.get_template(template+'.txt')
except:
try:
ht = loader.get_template(template+'.html')
except:
raise Exception('Neither `%(tmpl)s.txt` or `%(tmpl)s.html` could be found.' % {'tmpl':template})
else:
e = EmailMultiAlternatives(subject, ht.render(c), from_email, recipient_list)
e.content_subtype = 'html'
else:
e = EmailMultiAlternatives(subject, tt.render(c), from_email, recipient_list)
try:
ht = loader.get_template(template+'.html')
except:
pass
else:
e.attach_alternative(ht.render(c), 'text/html')
if send_immediately:
e.send()
return e

最佳答案
我无法重现您所描述的任何内容(类似于回答问题的拉米罗，也无法重现问题)。如果我有两个具有相同基本名称、不同扩展名、不同内容的模板，并从代码中剪切和粘贴以从 View 发送电子邮件，我会在发送的邮件中看到不同的内容(在 Gmail 上并检查“原始”) )。
您说您的 .html 和 .txt 文件不同，但根据您所说的一切，听起来您的 .html 文件确实具有 .txt 内容。您已经列出了文件系统和应用程序目录加载器:哪一个应该找到这些文件？也许在另一个正在查找的地方有一个杂散文件，其内容有错误？
shell 中的一些实验可能会帮助您进行调试。加载 .html 模板并查看它是否确实包含您认为的内容。例如:
>>> from django.template import loader
>>> from pprint import pprint
>>> template = 'emails/dun'
>>> ht = loader.get_template(template+'.html')
>>> pprint(ht.nodelist)
[<Text Node: '<p><strong>Mr. '>,
<Variable Node: user>,
<Text Node: '</strong>: Pay us $ '>,
<Variable Node: amt>,
<Text Node: ' before next Friday.</p>
'>]
验证 .html 版本与 .txt 版本是否不同:
>>> tt = loader.get_template(template+'.txt')
>>> pprint(tt.nodelist)
[<Variable Node: user>,
<Text Node: ': This is an important me'>,
<Variable Node: amt>,
<Text Node: '.
'>]
如果加载时相同，那么你需要调查一下为什么没有找到正确的模板文件，或者为什么找到的模板文件内容错误，答案与渲染无关() 代码。只有当它们在加载时不同并且在渲染时相同时才需要查看 render() 。
更新:因此，根据问题更新，加载的模板有所不同，因为每个模板都扩展了不同名称的基本模板。那么下一个问题是，这些基本模板是否不同？更改我的游戏场景以匹配您的游戏场景，至少就最初加载的模板扩展基本模板而言，我仍然无法重现该问题。我看到加载了不同的模板:
>>> from django.template import loader, Context
>>> from pprint import pprint
>>> template = 'emails/dun'
>>> ht = loader.get_template(template+'.html')
>>> pprint(ht.nodelist)
[<ExtendsNode: extends "emails/base.html">]
>>> tt = loader.get_template(template+'.txt')
>>> pprint(tt.nodelist)
[<ExtendsNode: extends "emails/base.txt">]
渲染方式不同:
>>> c = Context({'user': 'Joe', 'amt': '50.00'})
>>> tt.render(c)
u'\nJoe: This is an important message. You owe us $ 50.00.\n\n'
>>> ht.render(c)
u'<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xm
lns="http://www.w3.org/1999/xhtml">\n<head>\n<title></title>\n</head>\n<body>\n\n<p><strong>Mr. Joe</strong>: Pay us $ 5
0.00 before next Friday.</p>\n\n</body>\n</html>\n'
因为引用的基础模板内容不同:
>>> template = 'emails/base'
>>> ht = loader.get_template(template+'.html')
>>> pprint(ht.nodelist)
[<Text Node: '<!DOCTYPE html PUBLIC "-/'>,
<Block Node: title. Contents: []>,
<Text Node: '</title>
</head>
<body>
'>,
<Block Node: content. Contents: []>,
<Text Node: '
</body>
</html>
'>]
>>> tt = loader.get_template(template+'.txt')
>>> pprint(tt.nodelist)
[<Block Node: content. Contents: []>, <Text Node: '
'>]
>>>
