# Complete Blog CRUD — Key Parts
# blog/views.py
# class PostListView(ListView):
# model = Post
# template_name = 'blog/list.html'
# context_object_name = 'posts'
# paginate_by = 10
# def get_queryset(self):
# qs = Post.objects.filter(published=True)
# search = self.request.GET.get('q')
# if search:
# qs = qs.filter(
# Q(title__icontains=search) |
# Q(content__icontains=search)
# )
# category = self.request.GET.get('category')
# if category:
# qs = qs.filter(category__slug=category)
# return qs
# class PostDetailView(DetailView):
# model = Post
# template_name = 'blog/detail.html'
# def get_object(self):
# obj = super().get_object()
# Post.objects.filter(pk=obj.pk).update(
# views_count=F('views_count') + 1
# )
# return obj
# class PostCreateView(LoginRequiredMixin, CreateView):
# model = Post
# fields = ['title', 'content', 'category', 'tags']
# def form_valid(self, form):
# form.instance.author = self.request.user
# form.instance.published = True
# return super().form_valid(form)
# class PostUpdateView(LoginRequiredMixin, UpdateView):
# model = Post
# fields = ['title', 'content', 'category', 'tags']
# def get_queryset(self):
# return Post.objects.filter(author=self.request.user)
# class PostDeleteView(LoginRequiredMixin, DeleteView):
# model = Post
# success_url = reverse_lazy('blog:list')
# def get_queryset(self):
