夹层评论应用程序定制失败

Question

我正在使用Mezzanine来帮助构建一个我目前正在进行的项目，我在如何使COMMENTS\u应用程序正常工作时遇到了一个问题。我已经把我的自定义应用程序安装了一个应用程序，并表示它是注释应用程序，把这个

from modify.models import CustomComment 
from modify.forms import CustomCommentForm

def get_model():
     return CustomComment 
def get_form():
     return CustomCommentForm

在应用程序的init.py中。我已经把

^{pr2}$

作为我的模型，我仍然有这个错误，而且在我的一生中，我不知道如何修正它。我错过了什么？是什么导致了这个错误？这是回溯
