如何使用详细视图类限制对对象的访问

我试图将显示对象限制为创建它的用户。 是使用对象模型中的外键完成的吗？

前任： 用户1可以访问对象1 用户2可以访问对象2

此时，任何用户只需输入该对象的正确 URL 即可访问该对象。

文件views.py

from django.shortcuts import render
from django.http.response import Http404
from .models import Host
from django.views.generic.detail import DetailView
from django.views.generic.list import ListView
from django.contrib.auth.decorators import login_required
# Create your views here.


def index(request):
    return render(request, 'index.html')


class HostDetail(DetailView):

    model = Host

    def get_context_data(self, **kwargs):
        context = super(HostDetail, self).get_context_data(**kwargs)
        return context


class HostList(ListView):

    model = Host

    def get_queryset(self, **kwargs):

        qs = super(HostList, self).get_queryset(**kwargs).filter(perfil=self.request.user.perfil.id)
        return qs

文件 models.py

class Perfil(models.Model):

    usuario = models.OneToOneField(User, on_delete=models.CASCADE)
    zbx_user = models.CharField(max_length=255, null=False)
    pwd = models.CharField(max_length=255, null=False)
    nome = models.CharField(max_length=255, null=False)
    grupo = models.CharField(max_length=255, null=False)
    numero_hosts = models.IntegerField(null=True)

    def __str__(self):

        return self.nome

class Host(models.Model):

    host_name = models.CharField(max_length=120)
    templateid = models.PositiveIntegerField()
    tipo = models.PositiveIntegerField()
    ip = models.GenericIPAddressField()
    dns = models.CharField(max_length=120, default="")
    host_id = models.PositiveIntegerField()
    # Relacionamento 1 pra N com Perfil
    perfil = models.ForeignKey(Perfil, on_delete=models.CASCADE)

    def __str__(self):
        return self.host_name

文件 url.py

from django.conf.urls import url
from . import views
from django.conf.urls.static import static
from django.conf import settings
from .views import HostDetail, HostList

urlpatterns = [

    # Rota para index perfis
    url(r'^$', views.index, name='index'),
    url(r'^host/(?P<pk>\d+)$', HostDetail.as_view(), name='HostDetail'),
    url(r'^host/$', HostList.as_view(), name='HostList'),

Thanks

使用与您使用的相同的方法ListView。使用过滤查询集self.request.user.

您可能还想使用LoginRequiredMixin两个视图上，以便只有登录用户才能访问视图。

from django.contrib.auth.mixins import LoginRequiredMixin

class HostDetail(LoginRequiredMixin, DetailView):
    model = Host

    def get_queryset(self):
        qs = super(HostList, self).get_queryset().filter(perfil=self.request.user.perfil_id)
        return qs

    ...
