1：创建model
你的app／models.py
class User(models.Model):
phone=models.CharField(verbose_name='站名',max_length=100)
password=models.CharField(verbose_name='站名',max_length=100)
registTime = models.DateTimeField(max_length=250, verbose_name='加入时间',auto_now_add=True,blank=True)# auto_now_add=True第一次注册创建的时间
loginTime = models.DateTimeField(max_length=250, verbose_name='最近登陆',auto_now=True,blank=True)# auto_now=True每次登录都会更新这个时间
2：创建view
你的app／views.py
from django.http import HttpResponse,HttpResponseRedirect
from django.shortcuts import render,render_to_response
from django import forms
from rnapp.models import User
##定义UserForm表单用于注册和登录页面，ChangeForm表单用于修改密码页面
class UserForm(forms.Form):
phone = forms.CharField(label='用户名')
password = forms.CharField(label='密 码',widget=forms.PasswordInput())
#last_login = forms.DateTimeField()
class ChangeForm(forms.Form):
phone = forms.CharField(label='用户名')
old_password = forms.CharField(label='原密码',widget=forms.PasswordInput())
new_password = forms.CharField(label='新密码',widget=forms.PasswordInput())
def regist(request):
if request.method == 'POST':
uf = UserForm(request.POST)
if uf.is_valid():
phone = uf.cleaned_data['phone']
password = uf.cleaned_data['password']
##判断用户原密码是否匹配
user = User.objects.filter(phone = phone)
if user:
info = '用户名已存在!'
elif len(user) == 0:
info = '注册成功!'
user = User()
user.phone = phone
user.password = password
user.save()
return HttpResponse(info)
else:
uf = UserForm()
return render(request, 'public/regist.html', locals())
def login(request):
if request.method == 'POST':
##获取表单信息
uf = UserForm(request.POST)
if uf.is_valid():
phone = uf.cleaned_data['phone']
password = uf.cleaned_data['password']
##判断用户密码是否匹配
user = User.objects.filter(phone = phone)
if user:
passwd = User.objects.filter(phone = phone, password = password)
if passwd:
info = '登录成功！'
else:
info = '请检查密码是否正确!'
elif len(user) == 0:
info = '请检查用户名是否正确!'
return HttpResponse(info)
else:
uf = UserForm()
return render(request,'public/login.html', locals())
def change_pass(request):
if request.method == 'POST':
uf = ChangeForm(request.POST)
if uf.is_valid():
phone = uf.cleaned_data['phone']
old_password = uf.cleaned_data['old_password']
new_password = uf.cleaned_data['new_password']
##判断用户原密码是否匹配
user = User.objects.filter(phone = phone)
if user:
passwd = User.objects.filter(phone = phone , password = old_password )
if passwd:
User.objects.filter(phone = phone,password = old_password).update(password = new_password) ##如果用户名、原密码匹配则更新密码
info = '密码修改成功!'
else:
info = '请检查原密码是否输入正确!'
elif len(user) == 0:
info = '请检查用户名是否正确!'
return HttpResponse(info)
else:
uf = ChangeForm()
return render(request,'public/change.html',{'uf':uf})
def index(request):
return render(request, "index.html")
# Create your views here.
3:创建模板
你的app／template/public/regist.html
你的app／template/public/login.html
你的app／template/public/change.html
