python - AssertionError - 没有提供异常 - django

Question

我真的很困惑，不知道它想从我这里得到什么。

这是我的简单功能

def confirm_abo(request):
  try:
      abo = Abonnement.objects.get(id=int(request.GET.get('abocid')))
      abo.status = 1
      abo.save()
      link = "http://127.0.0.1:8000/delete_link/?abocid=" + str(abo.id)
      subject = "test subject"
      message = "test message" + link
      send_mail(subject, message, 'info@test.com', [abo.email], fail_silently=False)
      return render(request,'abo_confirm.html',{'abo':abo,'abo_success':'yes'})
  except: 
      return render(request,'abo_confirm.html',{'abo_success':''})#<-- problem

我进入最后一行

AssertionError at /confirm_abo/ No exception supplied

错误。

我在 django1.4 和 python 2.7 中。它一直工作到现在没有任何问题..

我做错了什么？

Answer 1

检查模板 abc_confirm.html 是否包含无效的标签用法，如下所示:

{% if x == '0' %}
...
{% else if x == '1' %}   {# used `else if` instead of `elif` %}
...
{% endif %}

可能导致AssertionError ..:

>>> from django.template import Template, Context
>>>
>>> t = Template('''
... {% if x == '0' %}
...              ..
... {% else if x == '1' %}
...              ..
... {% endif %}
... ''')
