django中Paginator怎么用

Paginator是Django中的一个分页工具，可以将查询结果按照每页显示的数量进行分页显示。使用方法如下：

1. 引入Paginator和EmptyPage异常：

from django.core.paginator import Paginator, EmptyPage

2. 在视图函数中进行查询：

from .models import MyModel

def my_view(request):
    my_objects = MyModel.objects.all()
    paginator = Paginator(my_objects, 10) # 每页显示10条数据
    page = request.GET.get('page') # 获取页码
    try:
        my_objects = paginator.page(page)
    except EmptyPage:
        my_objects = paginator.page(paginator.num_pages) # 超出范围则显示最后一页
    return render(request, 'my_template.html', {'my_objects': my_objects})

3. 在模板中进行渲染：

{% for my_object in my_objects %}
    <!-- 显示数据 -->
{% endfor %}

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

        <span class="current-page">
            Page {{ my_objects.number }} of {{ my_objects.paginator.num_pages }}.
        </span>

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

希望以上内容能够帮助你解决问题。
