Django2.0 分页的应用

#分页例子
from django.core.paginator import Paginator
def blog_list(request):
blog_all_list = models.Blog.objects.all()
paginator = Paginator(blog_all_list,1) #10个一页进行分页
page_num = request.GET.get('page', 1) #获取url页面参数没有默认显示第一页
page_of_blogs = paginator.get_page(page_num)

context = {}
context['page_of_blogs'] = page_of_blogs #得到每页的数据
context['blog_types'] = models.BlogType.objects.all()
# context['blogs_count'] =models.Blog.objects.all().count()
return render_to_response('blog_list.html', context)

#分页html代码
-- 分页页码样式和标签采用bootstrap的例子做的
-- 连接是https://v3.bootcss.com/components/#pagination
<nav aria-label="Page navigation">
<ul class="pagination">
<li>

{% if page_of_blogs.has_previous %} 
<a href="?page={{ page_of_blogs.previous_page_number }}" aria-label="Previous">
«
</a>
{% else %}

{% endif %}
</li>
{% for page_num in page_of_blogs.paginator.page_range %}
<li><a href="?page={{ page_num }}">{{ page_num }}</a></li>
{% endfor %}
<li>

{% if page_of_blogs.has_next %} 
<a href="?page={{ page_of_blogs.next_page_number }}" aria-label="Next">
»
</a>
{% else %}

{% endif %}
</li>
</ul>
</nav>

#总结
向前段传递分页对象page_of_blogs
对象属性：

- page_of_blogs.num_pages 总页数（最后一页）
- page_of_blogs.has_previous 是否有上一页
- page_of_blogs.previous_page_number 上一页页数
- page_of_blogs.has_next 是否有下一页
- page_of_blogs.next_page_number 下一页页数

判断上一页下一页代码：
-- 是否有下一页如果有就输出上一页图标
{% if page_of_blogs.has_next %}
<a href="?page={{ page_of_blogs.next_page_number }}" aria-label="Next">
»
</a>
{% else %}
-- 如果没有可以输出一个空或者输出一个没有a便签的图标

{% endif %}

#完整代码  包括上一页 下一页 首页 尾页
<nav aria-label="Page navigation">
  <ul class="pagination">
    <li>
      <!-- 上一页 -->
      {% if page_of_blogs.has_previous %} <!-- 是否有上一页 -->
        <a href="?page=1" aria-label="Previous">
          <span aria-hidden="true">首页</span> 
        </a>
        <a href="?page={{ page_of_blogs.previous_page_number }}" aria-label="Previous">
          <!-- <span aria-hidden="true">&laquo;</span> -->
          <span aria-hidden="true">上一页</span>
        </a>                  
      {% else %}
        <!-- <a href="?page=1" aria-label="Previous">
          <span aria-hidden="true">首页</span> 
        </a> -->
      {% endif %}
    </li>
      {% for page_num in page_of_blogs.paginator.page_range %}
        <li><a href="?page={{ page_num }}">{{ page_num }}</a></li>
      {% endfor %}
    <li>
      <!-- 下一页 -->
      {% if page_of_blogs.has_next %}  <!-- 是否有下一页 -->
        <a href="?page={{ page_of_blogs.next_page_number }}" aria-label="Next">
          <!-- <span aria-hidden="true">&raquo;</span> -->
          <span aria-hidden="true">下一页</span>
        </a>
        <a href="?page={{ page_of_blogs.paginator.num_pages }}" aria-label="Next">
          <span aria-hidden="true">尾页</span> 
        </a>                 
      {% else %}
          <!-- <span aria-hidden="true">&raquo;</span> --> 
        <!-- <a href="?page={{ page_of_blogs.end_index }}" aria-label="Next">
          <span aria-hidden="true">尾页</span> 
        </a> -->
      {% endif %}                  
    </li>
  </ul>
</nav>
