使用参数 '('l', 'o', 'n', 'd', 'o', 'n')' 和关键字反转 'places'未找到参数“{}”
Reverse for 'places' with arguments '('l', 'o', 'n', 'd', 'o', 'n')' and keyword arguments '{}' not found
Django 1.9.6
你能帮我理解我做错了什么吗？
该程序已尝试：['places/$']。好吧，这有点令人困惑。
/places/ + 参数 'london' 有效。我的意思是 http://localhost:8000/places/london/ 工作正常。
我很乐意在这里踢球。提前谢谢你。

我认为您的模型 get_absolute_url 有两个问题：
@models.permalink

return ('places', self.slug)
应该是

def get_absolute_url(self):
return ('place', (self.slug,))
