python - 导入错误 : No module named rest_framework. 授权 token

Question

我在我的项目中使用 django rest-framework (DRF) token 身份验证来在创建用户时创建 token 。在我从 DRF 文档中添加这一行之前，一切都很好:

url(r'^api-token-auth/', 'rest_framework.authtoken.views.obtain_auth_token'),

创建一个端点，在正确发布用户名和密码后为用户返回 token 。

它抛出这个错误:

ImportError: No module named rest_framework.authtoken

这很奇怪，因为 DRF 没有这一行就可以了，所以它必须包含在我的 PYTHONPATH 中。

我还运行了 python manage.py syncdb 和适当的迁移。

知道哪里出了问题吗？

设置.py:

THIRD_PARTY_APPS = (
        'south',  # Database migration helpers:
        'crispy_forms',  # Form layouts
        'avatar',  # for user avatars
        'rest_framework', # for rest
        'django_rq', # for aysnc
        'rest_framework_swagger', # for exploring the api
        'rest_framework.authtoken',
    )
INSTALLED_APPS = DJANGO_APPS + THIRD_PARTY_APPS + LOCAL_APPS

查看最后的回复 here .不要将整个 View 作为字符串包含，而是先导入“obtain_auth_token”，然后再引用它。

from rest_framework.authtoken.views import obtain_auth_token

...
url(r'^api-token-auth/', obtain_auth_token),
...

agconti 的进一步更新:

此问题源于使用:

urlpatterns = patterns("api.views",
    ...
    url(r'^api-token-auth/', 'rest_framework.authtoken.views.obtain_auth_token'),
    ...
)

因为 View 前缀。如果你想这样使用api-token-auth/你必须改成下面的方式或者使用Alex提供的解决方案:

urlpatterns = patterns('',
    ...
    url(r'^api-token-auth/', 'rest_framework.authtoken.views.obtain_auth_token'),
    ...
)
