Answer 1

检查您的models.py可能您错误输入了pub_date日期时间字段

Answer 2

有点晚了，但我也有这个问题，我找到了答案。将yor models.py文件更改为：

from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

class Choice(models.Model):
    poll = models.ForeignKey(Poll)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

pub_date在Django教程错误中无效
