我试图将 \'comment.html\' 包含到 store.html 中，并 store.html 扩展 base.html。
\n\n但是 Django 抛出错误comment.html (<class \'django.template.base.TemplateDoesNotExist\'>)\n
所有模板都在同一目录中。store.html工作正常，并且可以正常扩展，base.html没有任何问题。但是，当我包含comment.html在store.html错误中时，会抛出...\n我已使用{% include "comment.html" %}它来包含comment.html到store.html

self.cursor.execute("select (1) from eScraperInterfaceApp_scrapeddata where productURL = '%s' limit 1") % URL
错误
%不支持的操作数类型:'long'和'unicode'
productURL是unicode所以如何更换它...有人可以帮助我
我有一个模型,在我使用时会抛出错误 python manage.py syncdb
在这一行createdAt = models.DateTimeField(auto_add_now=True),错误是
