django中的分页不适用于第一页

from django.core.paginator import Paginator

class CustomPaginator(Paginator):
    def get_page(self, number):
        """
        Return a valid Page object for the given 1-based page number.
        """
        number = self.validate_number(number)
        bottom = (number - 1) * self.per_page
        top = bottom + self.per_page + self.orphans
        if top + self.orphans >= self.count:
            top = self.count
        return self._get_page(self.object_list[bottom:top], number, self)

from django.shortcuts import render
from .models import YourModel
from .utils import CustomPaginator

def your_view(request):
    queryset = YourModel.objects.all()
    paginator = CustomPaginator(queryset, 10)  # 每页显示10条数据
    page_number = request.GET.get('page')
    page_obj = paginator.get_page(page_number)
    return render(request, 'your_template.html', {'page_obj': page_obj})
