views和urls

#coding:utf-8

from django.shortcuts import render
from django.http import HttpResponse
from tb.models import Users
from django.contrib.auth.hashers import make_password,check_password

def reset_pwd(request):
    rs=""
    if request.method=="GET":
        return render(request,'chpwd.html',{'msg':rs})
    if request.method=="POST":
        username=request.POST.get('username')
        pwd=request.POST.get("password")
        new_pwd=request.POST.get("new")
        if pwd==new_pwd:
            rs="新密码和旧密码不能重复"
            return render(request,'chpwd.html',{'msg':rs})
        else:
            #先查询数据库是否有此用户名
            user_lst=Users.objects.filter(user_name=username).first()
            if not user_lst:
                #没这个用户
                rs="{}用户未注册".format(username)
                return render(request,'chpwd.html',{'msg':rs})
            else:
                #如果注册过，判断密码对不对
                is_pwd=check_password(pwd,user_lst.pwd)
                if is_pwd:
                    user=Users.objects.get(user_name=username)
                    user.pwd=make_password(new_pwd)
                    user.save()
                    rs="密码修改成功!"
                else:
                    rs="密码错误！"
                return render(request,'chpwd.html',{'msg':rs})

urls.py访问地址

# coding:utf-8

from django.conf.urls import url
from tb import views

urlpatterns = [
    # 新增用户
    url(r'^register/', views.register),
    url(r'^login/', views.login),
    url('^chpwd/',views.reset_pwd),
]

　实现效果如下
