我看到大量与此相关的问题,但我无法找出解决方案。
这是在 Django 1.4 和 Python 2.7 上。
data
是一个包含 UTF8 字符的字典。看到这一行:
render_to_response('application/app.html', data, context_instance=RequestContext(request))
模板被渲染,从那个输出值data
。
为什么它会爆炸,我该怎么做才能解决这个问题?
编辑:四处挖掘后,其中一部分data
包含lxml.objectify.ObjectifiedElement
. 基本上是一个可以像普通字典一样查询的 XML 元素。它产生的值似乎是正确的 unicode 字符串,如下所示:u'\xae\u2020\xa5\xa8\u02c6\xf8'
这是完整的堆栈跟踪:
