我正在将django项目从1.1.1迁移到1.2.1
现在，{% url %}标记既不起作用，也@models.permalink - 装饰get_absulute_url起作用
即。我得到了
TemplateSyntaxError at /
Caught TypeError while rendering: __init__() got an unexpected keyword argument 'error_message'
代表
<li><a href="{% url archive_talks %}">talks</a></li>
虽然url-pattern看起来像这样：
url(r'^archive/talks/$', 'talkapp.views.archive_talks', name="archive_talks"),
有没有人遇到同样的问题？有解决方案吗？

答案 0 :(得分：4)
此问题与实际{% url %}标记无关。您在该标签上点击它的原因是URL反转过程实际上导入了所有Django视图，并且在完全不同的地方出现错误：BlogForm类。
如果没有该表单的代码，很难确切地告诉那里有什么错误，虽然它确实传递了error_message参数，而不是error_messages（带有s）。
