Django:提交表单报错:RuntimeError: You called this URL via POST, but the URL doesn’t end in a slash and you have APPEND_SLASH set.

　　-解决方法：
　　　-　　　 RuntimeError: You called this URL via POST, but the URL doesn’t end in a slash and you have APPEND_SLASH set. 　　
　　　　　　　提示form的action地址最后不是/结尾的，而且APPEND_SLASH的值是Ture

　　  　　　　将from的action地址改为/结尾的就可以了 

　　 -　　 或者 
　　　　　　　修改settings:APPEND_SLASH=False
