Django框架Pagination分页实现代码实例-创新互联

一、自定义分页

1、基础版自定义分页

data = []
 
for i in range(1, 302):
  tmp = {"id": i, "name": "alex-{}".format(i)}
  data.append(tmp)
 
print(data)
def user_list(request):
 
  # user_list = data[0:10]
  # user_list = data[10:20]
  try:
    current_page = int(request.GET.get("page"))
  except Exception as e:
    current_page = 1
 
  per_page = 10
 
  # 数据总条数
  total_count = len(data)
  # 总页码
  total_page, more = divmod(total_count, per_page)
  if more:
    total_page += 1
 
  # 页面最多显示多少个页码
  max_show = 11
  half_show = int((max_show-1)/2)
 
  if current_page <= half_show:
    show_start = 1
    show_end = max_show
  else:
    if current_page + half_show >= total_page:
      show_start = total_page - max_show
      show_end = total_page
    else:
      show_start = current_page - half_show
      show_end = current_page + half_show
 
  # 数据库中获取数据
  data_start = (current_page - 1) * per_page
  data_end = current_page * per_page
 
  user_list = data[data_start:data_end]
 
  # 生成页面上显示的页码
  page_html_list = []
  # 加首页
  first_li = '
首页
'
  page_html_list.append(first_li)
  # 加上一页
  if current_page == 1:
    prev_li = '
上一页
'
  else:
    prev_li = '
上一页
'.format(current_page - 1)
  page_html_list.append(prev_li)
  for i in range(show_start, show_end+1):
    if i == current_page:
      li_tag = '
{0}
'.format(i)
    else:
      li_tag = '
{0}
'.format(i)
    page_html_list.append(li_tag)
 
  # 加下一页
  if current_page == total_page:
    next_li = '
下一页
'
  else:
    next_li = '
下一页
'.format(current_page+1)
  page_html_list.append(next_li)
 
  # 加尾页
  page_end_li = '
尾页
'.format(total_page)
  page_html_list.append(page_end_li)
 
  page_html = "".join(page_html_list)
 
  return render(request, "user_list.html", {"user_list": user_list, "page_html": page_html})
