如何在django中实现下一页

# views.py
from django.core.paginator import Paginator
from django.shortcuts import render

def my_view(request):
    # 获取当前页码，默认为1
    page = request.GET.get('page', 1)
    # 每页显示的数据量
    per_page = 10
    
    # 从数据库中获取所有数据
    all_data = MyModel.objects.all()
    
    # 使用Paginator类进行分页
    paginator = Paginator(all_data, per_page)
    
    try:
        # 获取当前页的数据
        current_page_data = paginator.page(page)
    except EmptyPage:
        # 如果页码超出范围，则返回第一页数据
        current_page_data = paginator.page(1)
    
    return render(request, 'my_template.html', {'data': current_page_data})


# my_template.html
{% if data.has_previous %}
    <a href="?page={{ data.previous_page_number }}">上一页</a>
{% endif %}

{% if data.has_next %}
    <a href="?page={{ data.next_page_number }}">下一页</a>
{% endif %}
