Question

我目前正在学习django并从Django Rest Framework学习教程。

问题如下。我有以下树：

.
./tutorial
./tutorial/manage.py
./tutorial/tutorial
./tutorial/tutorial/__init__.py
./tutorial/tutorial/__init__.pyc
./tutorial/tutorial/settings.py
./tutorial/tutorial/settings.pyc
./tutorial/tutorial/snippets
./tutorial/tutorial/snippets/__init__.py
./tutorial/tutorial/snippets/__init__.pyc
./tutorial/tutorial/snippets/admin.py
./tutorial/tutorial/snippets/apps.py
./tutorial/tutorial/snippets/apps.pyc
./tutorial/tutorial/snippets/migrations
./tutorial/tutorial/snippets/migrations/__init__.py
./tutorial/tutorial/snippets/models.py
./tutorial/tutorial/snippets/tests.py
./tutorial/tutorial/snippets/views.py
./tutorial/tutorial/urls.py
./tutorial/tutorial/wsgi.py

我通过添加

在settings.py中添加了依赖项

'rest_framework',
'snippets.apps.SnippetsConfig',

在INSTALLED_APPS中。

问题是，当我做ElbattoresMacbook:tutorial elbattore$ python manage.py makemigrations snippets时。我有以下错误：

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/anaconda/lib/python2.7/site-packages/django/core/management/__init__.py", line 367, in execute_from_command_line
    utility.execute()
  File "/anaconda/lib/python2.7/site-packages/django/core/management/__init__.py", line 341, in execute
    django.setup()
  File "/anaconda/lib/python2.7/site-packages/django/__init__.py", line 27, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/anaconda/lib/python2.7/site-packages/django/apps/registry.py", line 85, in populate
    app_config = AppConfig.create(entry)
  File "/anaconda/lib/python2.7/site-packages/django/apps/config.py", line 142, in create
    app_module = import_module(app_name)
  File "/anaconda/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named snippets

我做的有什么问题？我严格遵循http://www.django-rest-framework.org/tutorial/1-serialization/

但它不起作用......

谢谢你们

你做了两次这个步骤：

$ docker-compose --version
docker-compose version 1.16.1, build 6d1ac219
$ docker --version
Docker version 17.09.0-ce, build afdb6d4

...最终在cd tutorial内而不是./tutorial/tutorial。

您可以通过将./tutorial降低一个文件夹级别或将已安装的应用更改为snippets来解决此问题。我建议将文件夹降低一级。您的结构应如下所示：

tutorial.snippets.apps.SnippetsConfig

Django努力进行迁移
