在同一页上提交表单时保留django分页和搜索过滤器

from django.core.paginator import Paginator
from django.shortcuts import render, redirect

def my_view(request):
    # 获取分页和搜索过滤器的参数
    page_number = request.GET.get('page')
    page_size = request.GET.get('page_size')
    search_filter = request.GET.get('search_filter')

    # 将参数保存到context中
    context = {
        'page_number': page_number,
        'page_size': page_size,
        'search_filter': search_filter
    }

    # 处理表单提交逻辑
    if request.method == 'POST':
        # 表单验证和数据保存操作
        # ...

        # 重新构建URL，并将其作为重定向的目标URL
        redirect_url = f'/my_view/?page={page_number}&page_size={page_size}&search_filter={search_filter}'
        return redirect(redirect_url)

    # 获取数据并进行分页和搜索过滤
    data = MyModel.objects.all()
    if search_filter:
        data = data.filter(name__icontains=search_filter)
    paginator = Paginator(data, page_size)
    page = paginator.get_page(page_number)

    # 将分页和搜索过滤器的结果保存到context中
    context['data'] = page

    return render(request, 'my_template.html', context)
