Django实现分页

Django实现分页

views.py中

from django.core.paginator import Paginator
from django.shortcuts import render
from .models import Blog,BlogType


def blog_list(request):
    # 获取所有博客
    blog_all_list = Blog.objects.all()
    # 每10页进行分页
    paginator = Paginator(blog_all_list,10)
    page_num = request.GET.get('page',1)   # 获取url的页面参数
    # 根据页码获取每页数据  页码参数出错时，自动转为第一页
    page_of_blogs = paginator.get_page(page_num)
    currenter_num = page_of_blogs.number # 获取当前页码
    # 获取当前页码前后各2页的页码范围
    page_range = list(range(max(currenter_num-2,1),currenter_num))+list(range(currenter_num,min(currenter_num+2,paginator.num_pages)+1))
    # 加上省略页码标记
    if page_range[0] -1 >=2:
        page_range.insert(0,'...')
    if paginator.num_pages - page_range[-1] >=2:
        page_range.append('...')
    # 加上首页和尾页
    if page_range[0] !=1:
        page_range.insert(0,1)
    if page_range[-1] != paginator.num_pages:
        page_range.append(paginator.num_pages)
    blog_type_list = BlogType.objects.all()
    return render(request,'blog/blog_list.html',locals())

前端blog/blog_list.html中,借助于bootstrap

    

        
{% block heading_title %}博客列表{% endblock %}
        

            {% for blog in page_of_blogs.object_list %}
                
{{ blog.title }}
                

                    
                    {{ blog.blog_type }}
                    
                    发表日期:{{ blog.create_time|date:'Y-m-d H:i:s' }}
                
                
{{ blog.content|truncatechars:30 }}
                

            {% empty %}
                
暂无博客，敬请更新
            {% endfor %}
        
    
    

        

            {# 上一页 #}
            

                {% if page_of_blogs.has_previous %}
                    
                        «
                    
                {% else %}
                    «
                {% endif %}
            
            {# 页码 #}
            {% for page_num in page_range %}
                {# 当前页高亮 #}
                {% if page_num == page_of_blogs.number %}
                    
{{ page_num }}
                {% else %}
                    {# 省略页码 #}
                    {% if page_num == '...' %}
                        
{{ page_num }}
                    {% else %}
                        
{{ page_num }}
                    {% endif %}
                {% endif %}
            {% endfor %}
            {# 下一页 #}
            

                {% if page_of_blogs.has_next %}
                    
                        »
                    
                {% else %}
                    »
                {% endif %}
            
        
    
    
 一共有篇{{ blog_all_list|length }}博客，当前是{{ page_of_blogs.number }}页，一共有{{ page_of_blogs.paginator.num_pages }}页
