Python 属性错误：'；模块'；对象没有属性'；日期字段'；

在models.py文件中

from django.db import models

# Create your models here.

class Publisher(models.Model):
    name = models.CharField(max_length=30)
    address = models.CharField(max_length=50)
    city = models.CharField(max_length=60)
    state_province = models.CharField(max_length=30)
    country = models.CharField(max_length=50)
    website = models.URLField()

class Author(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=40)
    email = models.EmailField()

class Books(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)
    publishers = models.ForeignKey(Publisher)
    publication_date = models.Datefield()

当我运行命令时

$ python manage.py validate

我收到了错误信息

AttributeError: 'module' object has no attribute 'Datefield'

请帮忙。

应该用大写字母

F

因此，您的

书籍

模型应如下所示：

class Books(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)
    publishers = models.ForeignKey(Publisher)
    publication_date = models.DateField()  # <--- Typo was here

教材（models.Model）：
title=models.CharField（最大长度=100）
作者=模型。ManyToManyField（作者）
Publisher=型号。ForeignKey（Publisher）
发布日期=models.DateField（）#
