“模塊”對象沒有屬性“模型”

Question

我是python的新手。 考慮以下代碼：

from django.db import models


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 Book(models.Model):

    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)
    publisher = models.ForeignKey(Publisher)
    publication_date = models.DateField()

這是我的項目結構：

為什么要驗證時出現此錯誤？

復制粘貼的代碼。對我有用。您應該刪除自己的遷移，然后重試。
