urls.py同分页一
views.py
# encoding=utf-8
from django.shortcuts import render
# Create your views here.
def index(request):
#模拟数据,列表生成式
a_list = [i for i in range(1, 105)]
#获取当前页, 注意获取时是字符串，要转换为int
current_page = request.GET.get('p', 1)
current_page = int(current_page)
#数据切片
#data = a_list[:10]
#data = a_list[20: 30]
#每页显示10条数据,并且得与current_page发生关系
start = (current_page-1) * 10
end = current_page * 10
data = a_list[start: end]
########页码########
#total_count:数据总条数
#page_num:总页数
total_count = len(a_list)
page_num, y = divmod(total_count, 10)
#y为余数，y=0为假
if y:
page_num += 1
page_html_list = []
for j in range(1, page_num+1):
page_html = '<a href="/index/?p=%s">%s</a>' % (j, j)
page_html_list.append(page_html)
return render(request, 'index.html', {'data': data, 'page': page_html_list})
template
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<ul>
{% for d in data %}
<li>{{ d }}</li>
{% endfor %}
</ul>
{% for i in page %}
{{ i|safe }}
{% endfor %}
</body>
</html>
注意:{{ i|safe }}因为要保护模板，后台传过来的都按字符串显示<a>...</a>
如果要按特殊显示，必须确认传过来的数据安全，加上 ...|safe
