Django — Generic Views

ListView

from django.views.generic import ListView
from .models import Post

class PostListView(ListView):
    model = Post
    template_name = 'blog/list.html'
    context_object_name = 'posts'
    paginate_by = 10
    
    def get_queryset(self):
        return Post.objects.filter(published=True)

DetailView

class PostDetailView(DetailView):
    model = Post
    template_name = 'blog/detail.html'
    context_object_name = 'post'
    
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['comments'] = self.object.comments.all()
        return context

CreateView

from django.contrib.auth.mixins import LoginRequiredMixin

class PostCreateView(LoginRequiredMixin, CreateView):
    model = Post
    template_name = 'blog/form.html'
    fields = ['title', 'content']
    
    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

UpdateView

class PostUpdateView(UpdateView):
    model = Post
    template_name = 'blog/form.html'
    fields = ['title', 'content']

DeleteView

class PostDeleteView(DeleteView):
    model = Post
    template_name = 'blog/confirm_delete.html'
    success_url = reverse_lazy('post-list')

Mini Practice

1. Create a ListView with filtering
2. Add context data to DetailView
3. Use CreateView with authentication
4. Implement UpdateView and DeleteView
