Python 如何使用分页由这是行不通的

views.py

paginate\u by不起作用，而“get\u queryset”中的“if”语句不起作用，是否有任何方法可以处理此问题

class PostListView(ListView):
    model = Post
    template_name = 'all_users/public/main.html'
    context_object_name = 'posts'
    paginate_by = 3

    def get(self, request, **kwargs):
        if request.user.is_public:
            post = Post.objects.filter(patient=self.request.user).order_by('-date_posted')
            context = {
                'posts': post,
            }
            return render(request, self.template_name, context)

        else:
            query = self.request.session['query']
            post = Post.objects.filter(patient=User.objects.get(username=query)).order_by('-date_posted')
            context = {
                'posts': post,
            }
        return render(request, self.template_name, context)

Django将对源自

get\u queryset

的queryset进行分页。因此，您可以通过以下方式实现视图：

from django.contrib.auth.mixins import LoginRequiredMixin

class PostListView(LoginRequiredMixin, ListView):
    template_name = 'all_users/doctor/main.html'
    model = Post
    context_object_name = 'posts'
    paginate_by = 3

    def get_queryset(self, *args, **kwargs):
        super().get_queryset(*args, **kwargs).filter(
            author=self.request.user
        ).order_by('-date_posted')

编辑：或带有条件：

from django.contrib.auth.mixins import LoginRequiredMixin

class PostListView(ListView):
    template_name = 'all_users/doctor/main.html'
    model = Post
    context_object_name = 'posts'
    paginate_by = 3

    def get_queryset(self, *args, **kwargs):
        qs = super().get_queryset(*args, **kwargs)
        if self.request.user.is_public:
            qs = qs.filter(
                author=self.request.user
            )
        else:
            qs = qs.filter(
                patient__username=self.request.session['query']
            )
        return qs.order_by('-date_posted')

来自django.contrib.auth.mixins导入登录所需的mixin
类PostListView（ListView）：
template_name='all_users/doctor/main.html'
型号=员额
上下文\对象\名称='posts'
分页单位=3
def get_queryset（self、*args、**kwargs）：
qs=super（）.get_queryset（*args，**kwargs）
如果self.request.user.u是公共的：
qs=qs.filter(
author=self.request.user
)
其他：
qs=qs.filter(
患者\用户名=self.request.session['query']
)
返回qs.订单日期（'-date\u posted'）

注意：您可以将基于类的视图限制为具有

你的答案有效，但我想在这个类中添加IF-Else条件。如果Else条件在“get_queryset”中不起作用。你能帮我吗？

from django.contrib.auth.mixins import LoginRequiredMixin

class PostListView(ListView):
    template_name = 'all_users/doctor/main.html'
    model = Post
    context_object_name = 'posts'
    paginate_by = 3

    def get_queryset(self, *args, **kwargs):
        qs = super().get_queryset(*args, **kwargs)
        if self.request.user.is_public:
            qs = qs.filter(
                author=self.request.user
            )
        else:
            qs = qs.filter(
                patient__username=self.request.session['query']
            )
        return qs.order_by('-date_posted')
