Page对象

class Page(object_list, number, paginator)



Page方法
Page.has_next() 如果有下一页，返回True
Page.has_previous() 如果有上一页，返回 True
Page.has_other_pages() 如果有上一面或下一页，返回True
Page.next_page_number() 返回下一页的页码.如果不存在,抛出InvalidPage异常
Page.previous_page_number() 返回上一页的页码.如果不存在,抛出InvalidPage异常
Page.start_index() 返回当前页上的第一个对象，相对于分页列表的所有对象的序号
Page.end_index() 返回当前页上的最后一个对象，相对于分页列表的所有对象的序号



创建用户小例子
from django.core.paginator import Paginator
class UserViewV2(View):
    def get(self,request,*args,**kwargs):
        queryset = User.objects.all()
        paginator = Paginator(queryset,10)
        try:
            page = int(request.GET.get("page"))
        except:
            page = 1
        if page < 1:
            page = 1
        page = paginator.page(page)
        data = [{"id":user.id,"username":user.username,"email":user.email} for user in page.object_list]
        return JsonResponse(data,safe=False)

    def post(self,request,*args,**kwargs):
        username = request.POST.get("username")
        userpass = request.POST.get("userpass")
        email = request.POST.get('email')
        if not username or userpass or not email:
            return JsonResponse({"errormsg":"参数有误！"})
        user = User.objects.create(username,email,userpass)
        return JsonResponse({"id":user.id,"username":user.username,"email":user.email})
