我收到错误.accepted_renderer没有设置响应resp api django。

I am getting the error ".accepted_renderer not set on Response resp api django".

我正在关注django rest-api教程。
Django版本我使用1.8.3
我按照教程直到第一部分。它工作正常但是当我继续发送响应的第二部分时，我收到一个错误

Cannot apply DjangoModelPermissions on a view that does not have `.queryset` property or overrides the `.get_queryset()` method.

然后我尝试其他方式我得到

Then i tried other ways i got

.accepted_renderer not set on Response resp api django

请帮助我出来我认为它的许可问题。

Please help me out. I think its permission issue.

推荐答案

您可能已将 DjangoModelPermissions 您的设置中的默认权限类。如下所示：

You probably have set DjangoModelPermissions as a default permission class in your settings. Something like:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.DjangoModelPermissions',
    )
}

DjangoModelPermissions 只能应用于具有 .queryset 属性或 .get_queryset（）方法的视图。

DjangoModelPermissions can only be applied to views that have a .queryset property or .get_queryset() method.

由于教程2使用FBV，您可能需要将其转换为CBV，或者简单的方法是为该视图指定不同的权限类。
您必须在视图中使用 api_view 装饰器。然后，您可以定义权限，如下所示：

Since Tutorial 2 uses FBVs, you probably need to convert it to a CBV or an easy way is to specify a different permission class for that view. You must be using the api_view decorator in your view. You can then define permissions like below:

from rest_framework.decorators import api_view, permission_classes
from rest_framework import permissions

@api_view([..])
@permission_classes((permissions.AllowAny,))
def my_view(request)
    ...

要解决渲染器错误，您需要将相应的渲染器添加到您的设置。

To resolve the renderer error, you need to add the corresponding renderer to your settings.

REST_FRAMEWORK = {
    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.<corresponding_renderer>',
        ...
    )
}
