python之为什么我得到 python manage.py syncdb 的错误 (IndentationError : unexpected indent)

from django.db import models 
 
 
class Post(models.Model): 
    title = models.CharField(max_length=100) 
    content = models.CharField(max_length=1000) 
    created = models.DateField() 
    modified = models.DateField() 

python manage.py syncdb 错误:

请您参考如下方法:

您是否在文件中混用了制表符和空格？这是此类错误的最常见原因。
