通过第一章和第三章创建级别目录
所需级别目录
所需代码
注意：所有的html页面都在templates文件夹中
views.py
from django.shortcuts import render,redirect
from django import http
from .models import *
# Create your views here.
def index(request):
books=Articles.objects.all() #查找所有书籍
print(books)
return render(request,"index.html",context={"books":books})
def login(request):
#数据提交给了login函数
#用请求的方式分别进行处理
if request.POST:
name=request.POST.get("uname")
pwd=request.POST.get("pwd")
users=Users.objects.filter(username=name,password=pwd)
if users:
return redirect("show/")
else:
return http.HttpResponse("用户名或密码错误")
return render(request,"login.html")
def zhuce(request):
if request.POST:
name = request.POST.get("name")
email = request.POST.get("email")
pwd = request.POST.get("pwd")
repwd = request.POST.get("repwd")
Users.objects.create(username=name,email=email,password=pwd)
if pwd==repwd:
return redirect("/")
else:
http.HttpResponse("两次密码输入不一致")
return render(request,"zhuce.html")
urls.py
注意：是应用的urls.py文件
from django.contrib import admin
from django.urls import path
from . import views
urlpatterns = [
path('', views.login),
path('show/', views.index),
path('zhuce/',views.zhuce),
]
models.py
from django.db import models
# Create your models here.
class Users(models.Model):
class Meta:
db_table="users" #描述原数据的内部类
id=models.AutoField(primary_key=True,db_column="id")
username = models.CharField(max_length=30)
email = models.CharField(max_length=50,null=True)
password = models.CharField(max_length=30,null=True)
def __str__(self):#魔法函数，用于打印对象时，显示对象中的某个信息
return self.email
class Articles(models.Model):
class Meta:
db_table="articles"
id=models.AutoField(primary_key=True,db_column="id")
