感谢@furas为我的问题提供了解决方案。我想我现在明白出了什么问题。我为任何可能遇到类似问题的人提供解决方案代码

视图.py

from django.views.generic import ListView from .models import Shoes class ShoeListView(ListView): model = Shoes template_name = 'shoes/shoes-list.html' context_object_name = 'shoes' paginate_by = 1 def get_context_data(self, **kwargs): if 'shoespp' in self.request.GET: self.paginate_by = self.request.GET.get('shoespp', 2) shoes = super().get_context_data(**kwargs) shoes['last_shoespp'] = self.request.GET.get('shoespp') return shoes

在您当前的代码中，它在开始时执行request.GET，甚至在它将HTML发送到浏览器之前，用户可以单击List shoes

我认为它应该在服务器从浏览器获得请求时执行的某个函数中

但是另一个问题可能是这个页面使用<form>发送GET，但是分页中的每个链接都是作为GET发送的，所以您可能需要检查shoespp是否真的是发送的

我不能测试它，但它可以是这样的

class ShoeListView(ListView):
    model = Shoes
    template_name = 'shoes/shoes-list.html'
    context_object_name = 'shoes'

    paginate_by = 2  # set some value at start

    def get_context_data(self, **kwargs):
        # change value when get new value from browser
        if 'shoespp' in self.request.GET:
             self.paginate_by = self.request.GET.get('shoespp', 2)

        context = super().get_context_data(**kwargs)

        return context

另请参见问题How do I use pagination with Django class based generic ListViews?第二个答案中的代码
