如何在django中对带有分页的单页博客使用基于类的视图

from django.views.generic import ListView
from django.core.paginator import Paginator

from .models import Blog

class BlogListView(ListView):
    model = Blog
    template_name = 'blog_list.html'
    context_object_name = 'blogs'
    paginate_by = 10

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        blogs = context['blogs']
        paginator = Paginator(blogs, self.paginate_by)
        page_number = self.request.GET.get('page')
        page_obj = paginator.get_page(page_number)
        context['page_obj'] = page_obj
        return context

from django.urls import path
from .views import BlogListView

urlpatterns = [
    path('blogs/', BlogListView.as_view(), name='blog_list'),
]

{% for blog in page_obj %}
    <h2>{{ blog.title }}</h2>
    <p>{{ blog.content }}</p>
{% endfor %}

<div class="pagination">
    <span class="step-links">
        {% if page_obj.has_previous %}
            <a href="?page=1">&laquo; first</a>
            <a href="?page={{ page_obj.previous_page_number }}">previous</a>
        {% endif %}

        <span class="current-page">{{ page_obj.number }}</span>

        {% if page_obj.has_next %}
            <a href="?page={{ page_obj.next_page_number }}">next</a>
            <a href="?page={{ page_obj.paginator.num_pages }}">last &raquo;</a>
        {% endif %}
    </span>
</div>
