我找不到此代码中的错误。我尝试隔离问题，但是当我将相关代码复制到一个单独的文件中时正常工作。问题必须与周围的代码有关，但我不知道它是如何相关的。这是一切：
问题在于“激活您的项目帐户”电子邮件。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
这两个版本的电子邮件中“text here”相同，但实际文件中不是，尝试发送时不是来自不同脚本的电子邮件。这是代码：
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',

我无法重新创建任何类似你所描述的东西（类似于拉米罗谁回答了票，也无法重现问题）。如果我有两个模板具有相同的基本名称，不同的扩展名，不同的内容，以及从代码剪切和粘贴以从视图发送电子邮件，我会在发送的邮件中显示不同的内容（在Gmail上并检查“原始” ）。
你说你的.html和.txt文件是不同的，但根据你所说的一切，它确实听起来你的.html文件有.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？也许在另一个看起来内容错误的地方有一个迷路文件？
shell中的一些实验可能有助于您进行调试。加载.html模板，看看它是否真的包含您的想法。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: '.
'>]
如果加载时它们是相同的，那么你需要查看为什么没有找到正确的模板文件或为什么找到的文件具有错误的内容，并且答案与渲染无关（）代码。只有在加载时它们不同并且在渲染时相同才会查看render（）是必要的。
更新：因此，基于问题更新，加载的模板是不同的，因为每个模板都扩展了不同命名的基本模板。那么接下来的问题是，那些基本模板是不同的？更改我的娱乐场景以匹配您的，至少就最初加载的模板扩展基本模板而言，我仍然无法重新创建问题。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">]
以不同的方式呈现：
>>> 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'
因为引用的基本模板具有不同的内容：
>>> 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: '
'>]
>>>

get_template()在settings.TEMPLATE_LOADERS
TEMPLATE_LOADERS通常是根据filesystem和app_directories
app_directories检查所有INSTALLED_APPS模板
因此，我会检查您settings.INSTALLED_APPS所有包含'电子邮件'文件夹的模板，并重命名您的模板，或将您想要的模板放在INSTALLED_APPS列表中。

仅供参考，我想我终于发现它是Django开发服务器的错误！当我将它切换到生产并在我的apache服务器上运行时，我似乎没有这个问题。
