Question

我正在通过虔诚地阅读this book来学习Django。我在第5章：模型，一切正常（在InteractiveConsole中），直到我到达Basic Data Access。

epqrs@epqrs:~/webapps/djcode/mysite$ pwd
/home/epqrs/webapps/djcode/mysite
epqrs@epqrs:~/webapps/djcode/mysite$ python ../manage.py shell
Python 2.7.3 (default, Sep 26 2012, 21:51:14)

Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from books.models import Publisher
Traceback (most recent call last):

ImportError: No module named books.models
>>> import sys

我不知道为什么我会得到 ImportError：没有名为books.models的模块。
books 目录位于当前目录 mysite （/ home / epqrs / webapps / djcode / mysite / books）下。

Answer 1

我必须将其更改为：

from books.models import Publisher, Author, Book

所以基本上，我不得不把mysite部分拿走。另外，将已安装的应用从'mysite.books'更改为'books'

我希望它有所帮助

Answer 2

我不得不做

from mysite.books.models import Publisher

让它发挥作用。

ImportError：没有名为books.models的模块
