使用 django-rest framework-generics 时如何修复 TypeError

Question

我正在学习如何使用基于 class 的通用视图，但我一直收到类型错误

from invoice.models import Invoice
from invoice.serializers import InvoiceSerializer
from rest_framework import generics


class InvoiceList(generics.ListCreateAPIView):
    queryset = Invoice.objects.all()
    serializer_class = InvoiceSerializer


class InvoiceDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Invoice.objects.all()
    serializer_class = InvoiceSerializer

serialzers.py
from rest_framework import serializers

from .models import Invoice


class InvoiceSerializer(serializers.ModelSerializer):
    class Meta:
        model = Invoice
        fields = "__all__"

urls.py
from django.urls import path
from invoice import views
from rest_framework.urlpatterns import format_suffix_patterns

urlpatterns = [
    path('invoice/', views.InvoiceList),
    path('invoice/<int:pk>/', views.InvoiceDetail),
]

urlpatterns = format_suffix_patterns(urlpatterns)

我收到类型错误消息“init() takes 1 positional argument but 2 were given”

Answer 1

您在 urls.py 中的导入看起来有误。在 urls.py 中，尝试这样的操作：

from django.urls import path
from .views import InvoiceList

path('invoice/', InvoiceList.as_view(), name="invoice"), # name can be anything you want.

我没用过format_suffix_patterns，所以你可以把那条线拿下来试试看行不行。
