Exception Type: TypeError at /admin/cms/page/5/advanced-settings/
Exception Value: __str__ returned non-string (type __proxy__)
问题似乎是value = str(value)没有返回字符串，尽管据说值是“继承最近祖先的模板”。我不确定这里发生了什么。
显然，它返回__proxy__类型，根据其他问题，该类型是用于翻译的类型。我该怎么做才能解决此问题？我需要访问页面的设置才能更改其使用的html模板。

我遇到了同样的问题-在我的settings.py中设置I18N=True可以解决问题。
如果这不起作用，请尝试点安装django-parler，看看是否有帮助。
答案 1 :(得分：0)
对于其他有相同问题的人。 设置I18N不得设置为False。 如果您的目标是停用多语言站点，则可以在urls.py中删除“ i18n_patterns”。
