AttributeError:“tuple”对象在Django Rest框架中没有基于函数视图的“get\u extra\u actions”属性

django-rest-framework django

图形\u数据/视图.py

@api_view(http_method_names=['GET'])
def my_func(request):

    print(request)

    return Response({'message': 'success'})

从django.url导入路径

app_name = 'graph_data'
urlpatterns = [
    path('my_func/<contact_id>', my_func, name='my_func')
]

并在主应用程序中包含图形url网址.py

router = routers.SimpleRouter()
router.register(r'graph/', include('graph_data.urls'), base_name='graph_data')

urlpatterns = [
    path('', include(router.urls))
]

AttributeError: 'tuple' object has no attribute 'get_extra_actions'

路由器的注册函数需要一个viewset,所以不可能以您想要的方式包含图形的url。

get_extra_actions 是ViewSet类的方法,并且 include 返回元组。因此,您可以忽略此错误,因为它在构建路由时尝试对include返回的元组调用此函数。

改为像这样包含图形URL:

urlpatterns = [
    path(r'graph/', include(('graph_data.urls','graph_data'), namespace='graph_data')),
]
