Question

from django.shortcuts import render
from django.http import HttpResponse
from django.views.generic import TemplateView,ListView,DetailView
from django.contrib.auth.mixins import LoginRequiredMixin
from .models import Post


# Create your views here.

def index(request):
  return HttpResponse("Hello, world.")


class HomePageView(LoginRequiredMixin,ListView):

  model = Post
  template_name = 'home.html'
  context_object_name = 'deeppost'
  def get_context_data(self, **kwargs):
    # Call the base implementation first to get a context
    context = super().get_context_data(**kwargs)
    # Add in a QuerySet of all the books
    context['deeppost'] = Post.objects.filter(author=request.user)
    return context

每次我使用author=request.user时，都会收到错误消息：

Answer 1

您在不使用CBV - 列表视图实例的情况下直接访问request。您需要访问通用视图中的请求对象，如下所示

self.request.user

Answer 2

您需要使用self.request

  class HomePageView(LoginRequiredMixin,ListView):


  model = Post
  template_name = 'home.html'
  context_object_name = 'deeppost'
  def get_context_data(self, **kwargs):
    # Call the base implementation first to get a context
    context = super().get_context_data(**kwargs)
    # Add in a QuerySet of all the books
    context['deeppost'] = Post.objects.filter(author=self.request.user)
    return context
