django-python makemigrations

对不起，我是Django和Python的新手

无论如何，我正在mac上运行Python2.7，并试图在这里创建我的第一个项目。 尝试shell命令python manage.py makemigrations时出错。 我之前升级了pip，安装pip2-升级pip，否则Django无法安装

所以我不知道是django版本的问题还是

(mydjangoblog) ninodidoxxx:mydjangoblog antoninodanselmo$ python manage.py makemigrations

设置.py

任何帮助都将不胜感激。谢谢

您应该在def和_str_______________和_unicode之间留出一个空格__

它应该如下所示

#python 3
    def __str__(self):
        return self.titolo

#python 2
    def __unicode__(self):
        return self.titolo

好的，我做了，但现在还有其他事情要做/Users/antoninodanselmo/Desktop/mydjangoblog/mydjangoblog/posts/models.py，第11行，在posts data=models.datatimefielddauto\u now=False，auto\u now\u add=True AttributeError:'module'object没有属性DataTimeField'@antoniod'Anselmo，有什么新的错误，请用最新的问题编辑问题，因为那是日期而不是数据，检查拼写…我刚刚修好了…这是我的意大利根潜入…无论如何谢谢现在它工作了：太好了，很高兴我帮助了。
