django和python ./manage.py makemigrations执行错误

Question

这是myles.py中的代码

from django.db import models
from django.utils import timezone
   class Book(models.Model):
title = models.CharField(max_length = 200)
author = models.CharField(max_lenght = 200)
description = models.TextField()
publish_date = models.DateField(Default= timezone.now)

当我输入./manage.py makemigrations执行错误时 这就是我所看到的嘘 仍然错误没有控制空间知道什么时候我指向鼠标到django它出现未解决的参考'django'虽然我安装它pip安装django == 1.8我每次运行sudo pip安装--ignore-installed virtualenvwrapper因为当我使用workon bookstore-django它直到我运行sudo pip install才会执行--ignore-installed virtualenvwrapper我在这个领域太初学了

Answer 1

Charfield部分应为CharField。

在/Users/bavlymorcos/Desktop/development/bookstore/store/models.py中，行号。 6，

应该是

title = models.CharField(max_length = 200)

即。 F in field应该是Capital。 （CharField而不是Charfield）

Answer 2

我解决了问题谢谢你们

问题出在model.py中我将其更改为

 from django.db import models

 from django.utils import timezone


class Book(models.Model):
   title = models.CharField(max_length=200)
   author = models.CharField(max_length=200)
   description = models.TextField()
   publish_date = models.DateField(default=timezone.now)
