Question

我在项目中使用django rest-framework，（DRF），令牌身份验证来创建用户时创建令牌。一切都很有效，直到我从DRF文档中添加这一行：

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返回用户的令牌。

它抛出了这个错误：

ImportError: No module named rest_framework.authtoken

这很奇怪，因为DRF在这条线上很好，所以它必须包含在我的PYTHONPATH中。

我还运行了python manage.py syncdb和相应的迁移。

知道可能出现什么问题吗？

Settings.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

查看上一个回复here。不要将整个视图包含为字符串，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'),
    ...
)

因为视图前缀。如果您想以这种方式使用api-token-auth/，则必须将其更改为以下或使用Alex提供的解决方案：

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

ImportError：没有名为rest_framework.authtoken的模块
