python - 属性错误 : 'module' object has no attribute 'model'

Question

谁能帮我解决这个问题..

from django.db import models

# Create your models here.
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 = models.CharField(max_length=200)
    votes = models.IntegerField()

运行:

c:\projects\mysite>python manage.py sql polls
Traceback (most recent call last):

它被称为 models.Model 而不是 models.model(区分大小写)。像这样修复您的投票模型 -

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