通过django默认的权限管理来管理权限即可，我们在基础上进行一些第三方扩展
下面给出一个权限控制的示例，这里url路径转发的时候需要添加默认的 别名，我们需要修改的也是这些别名
models.py
class UserProfile(models.Model):
user = models.OneToOneField(User)
name = models.CharField(max_length=64)
school = models.ForeignKey('School')
def __unicode__(self):
return self.name
class Meta:
permissions =(('view_customer_list', u"可以查看客户列表"),
('view_customer_info',u"可以查看客户详情"),
('edit_own_customer_info',u"可以修改自己的客户信息"),
('view_teacher_list',u"可以查看老师列表"),
('view_school_list',u"可以查看学校列表"),
)permissions.py 这边采取的是装饰的写法

def teachers(req):
teachers_list=models.UserProfile.objects.all()
return render(req,'crm/teachers.html',{'teachers_list':teachers_list})◆ 权限验证(1)
views 中验证
if not request.user.has_perm('crm.view_teachers_list')
return HttpResponse('Forbidden')
◆ 权限验证(2)
Template 中的权限检查
{% if perms.crm.view_teachers_list %}
有权限
{% endif %}前端权限判断截图如下：
