请求大佬支援！Django中使用BaseDetailView报错。

Question

环境：Python3.8 + Django3.0

urls.py

path('detail/<int:pk>/', views.BaseDetailView.as_view())

views.py

from django.http import JsonResponse
from .models import Blog
from django.views.generic.detail import BaseDetailView

class BlogDetailView(BaseDetailView):
    model = Blog

    def render_to_response(self, context):
        blog = context['object']
        data = {
            'blog': {
                'id': blog.id,
                'title': blog.title,
                'content': blog.content,
                'author': {
                    'id': blog.author.id,
                    'username': blog.author.username
                }
            }
        }
        return JsonResponse(data)

请求URL：

http://127.0.0.1:8000/blog/detail/1/

报错：

ImproperlyConfigured at /blog/detail/1/

BaseDetailView is missing a QuerySet. Define BaseDetailView.model, BaseDetailView.queryset, or override BaseDetailView.get_queryset().

Answer 1

BaseDetailView缺少QuerySet。定义BaseDetailView.model, BaseDetailView.queryset，或覆盖BaseDetailView.get_queryset().

所以你可以给quertset赋值
queryset = 某个model.objects.all()

或者重写get_queryset方法，
def get_queryset(self):
return 某个model.objects.all()

学学djangorestfrmawork吧
