按照DjangoBook所述创建我的第一个应用

问题描述

我正在阅读DjangoBook 2.0版，我刚刚创建了我的第一个应用程序，并将其添加到settings.py中的INSTALLED_APPS设置属性中

I'm reading the DjangoBook version 2.0, and i've just created my first app and added it to INSTALLED_APPS setting attribute in settings.py

我已使用:

因此，它的名字是'books'.

therefore, it's name is 'books'.

我添加了书中写的模型，

i added the models as written on the book,

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()

在验证添加的应用程序之后，使用

After validating the added app, using

我收到以下输出:

* 我添加到INSTALLED_APPS的数据是"mysite.books"，因为我的项目名称是mysite.

* The data i added to INSTALLED_APPS is 'mysite.books' because my project's name is mysite.

我的行为出了什么问题?
