day11 日志功能(扩展)
一、添加路由
查看日志路由 urls.py
模型modes.py
# 日志表
class Log(models.Model):
id = models.AutoField(primary_key=True)
ip = models.CharField(max_length=64, verbose_name='访问IP', help_text='访问用户的IP地址')
time = models.DateTimeField(auto_now_add=True, verbose_name='访问时间', help_text='该用户的访问时刻')
url = models.CharField(max_length=64, verbose_name='访问的URL', help_text='该用户访问的URL地址')
device = models.CharField(max_length=256, null=True, verbose_name='访问的浏览器', help_text='该用户是用什么浏览器访问的')
platform = models.CharField(max_length=256, null=True, verbose_name='访问的系统', help_text='该用户用的是什么操作系统')
# 定义这个表中默认显示的字段
def __str__(self):
return self.ip
# 定义这个表在admin后台中显示的别名
class Meta:
ordering = ['id']
verbose_name_plural = '日志'
path('log/', views.log, name='log'),
添加视图函数view.py
添加和查看日志log(其中包含分页器)
from django.core.paginator import Paginator
def log(request):
log_num = models.Log.objects.count()
page_num_int = int(request.GET.get('page', 1))
log_list = models.Log.objects.all()
paginator = Paginator(log_list, 10)
if paginator.num_pages > 9:
if page_num_int - 4 < 1:
page_range = range(1, 9)
elif page_num_int + 4 > paginator.num_pages:
page_range = range(paginator.num_pages - 8, paginator.num_pages + 1)
else:
page_range = range(page_num_int - 4, page_num_int + 4)
else:
page_range = paginator.page_range
page = paginator.page(page_num_int)
return render(request, 'other/Log.html', locals())
