Django分页笔记

1。在views.py视图里面导入

from django.core.paginatorimport Paginator,EmptyPage,PageNotAnInteger

2.定义函数

def admin_yqinfor(request):

cursor.execute("select * from baijiahao ")

# bjh_list=models.baijiahao.objects.raw("select * from baijiahao ")

bjh_list= cursor.fetchall()

paginator_obj = Paginator(bjh_list, 10)

collapse = ["collapseOne", "collapseTwo", "collapseThree", "collapseFour", 'collapseFive',

"collapseSix", "collapseSeven", "collapseEight", "collapseNine", 'collapseTen', ]

zip_data =zip(bjh_list, collapse)

print(zip_data)

# print(bjh_list[id])

if request.method =='GET':

page = request.GET.get("page")

try:

page_of_blogs = paginator_obj.get_page(page)

except PageNotAnInteger:

page_of_blogs = paginator_obj.page(1)

except EmptyPage:

page_of_blogs = paginator_obj.page(paginator_obj.num_pages)

current_page_num = page_of_blogs.number

page_range =list(range(max(current_page_num -3, 1), current_page_num)) \

+list(range(current_page_num, min(current_page_num +3, paginator_obj.num_pages) +1))

if page_range[0] -1 >=2:

page_range.insert(0, '....')

if paginator_obj.num_pages - page_range[-1] >=2:

page_range.append('....')

if page_range[0] !=1:

page_range.insert(0, 1)

if page_range[-1] != paginator_obj.num_pages:

page_range.append(paginator_obj.num_pages)

return render(request,'admin_yqinfor.html',{'bjh_list':bjh_list,'page_of_blogs':page_of_blogs,

'page_range':page_range,'zip_data':zip_data})

3.在HTML里面显示

{%for row in page_of_blogs %}
