python - Django - 缺少 1 个必需的位置参数 : 'request'

Question

我遇到了错误

get_indiceComercioVarejista() missing 1 required positional argument: 'request'

尝试访问方法 get_indiceComercioVarejista 时。我不知道它有什么问题。

from rest_framework.views import APIView
from rest_framework.response import Response

class ChartData(APIView):

    authentication_classes = []
    permission_classes = []

    def get(self, request, format=None):

         data = {
            'customer' : 10,
            'sales': 100
        }

        return Response(data)

    def get_indiceComercioVarejista(self, request, format=None):
        data = {
            'customer' : 10,
            'sales': 100
        }
        return Response(data)

from django.conf.urls import url
from . import views
from django.contrib.auth.views import login

urlpatterns = [
    url(r'^$', views.home),
    url(r'^login/$', login, {'template_name': 'Oraculum_Data/login.html'}),
    url(r'^cancerColo/$', views.cancerColo),
    url(r'^educacao/$', views.educacao),
    url(r'^comercio/$', views.comercio),
    url(r'^saude/$', views.saude),
    url(r'^api/chart/data/$', views.ChartData.as_view()),
    url(r'^api/chart/indiceVolumeReceitaComercioVarejista/$', views.ChartData.get_indiceComercioVarejista)
]

有人可以帮帮我吗？

request 作为第一个参数传递。您的第一个参数是 self。

这就是为什么从 ChartData 类中提取 get_indiceComercioVarejista 是个好主意:

def get_indiceComercioVarejista(request, format=None):
    data = {
        'customer' : 10,
        'sales': 100
    }
    return Response(data)
