Django 分页操作的实现示例

from django.core.paginator import Paginator

# 假设我们有一个模型对象列表 query_set
query_set = MyModel.objects.all()

# 每页显示 10 条数据
per_page = 10

# 创建分页器对象
paginator = Paginator(query_set, per_page)

# number 是用户请求的页码，例如从 URL 参数中获取
number = request.GET.get('page', 1)  # 默认显示第一页

# 获取分页后的 Page 对象
page = paginator.get_page(number)

current_data = page.object_list

current_page_number = page.number

total_pages = paginator.num_pages

has_next_page = page.has_next

has_previous_page = page.has_previous

next_page_num = page.next_page_number if page.has_next else None

previous_page_num = page.previous_page_number if page.has_previous else None

<!-- 渲染当前页的数据 -->
<ul>
    {% for item in page.object_list %}
        <li>{{ item.some_field }}</li>
    {% endfor %}
</ul>

<!-- 分页导航 -->
<div>
    <span>Page {{ page.number }} of {{ page.paginator.num_pages }}</span>
    {% if page.has_previous %}
        <a href="?page=1" rel="external nofollow" >&laquo; first</a>
        <a href="?page={{ page.previous_page_number }}" rel="external nofollow" >previous</a>
    {% endif %}

    <span>
        {% for i in page.paginator.page_range %}
            {% if page.number == i %}
                <strong>{{ i }}</strong>
            {% else %}
                <a href="?page={{ i }}" rel="external nofollow" >{{ i }}</a>
            {% endif %}
        {% endfor %}
    </span>

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