AttributeError:'module'对象没有属性'model'

Question

任何人都可以帮我解决这个问题..

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):

Answer 1

它被称为models.Model而不是models.model(区分大小写).修复你的民意调查模型 -

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

希望有帮助......

我也有同样的错误,但我注意到我输入了外国*k*ey而不是外国*K*ey,(大写K)如果有新手,请查看拼写和上限.

Answer 3

正如错误消息最后一行所示：models文件中的模块c:\projects\mysite..\mysite\polls\models.py不包含 class model。这个错误发生在类的定义中Poll：

class Poll(models.model):

model类的定义中的类拼写错误Poll，或者模块中的类拼写错误models。另一种可能性是模块中完全缺少它models。也许它在另一个模块中或者尚未在models.
