day04 基于python Django 编写简单的图书管理系统--单表
整个目录如下：
首先html文件有三个：查看、新增和编辑页面
查看页面：book
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>图书馆</title>
<link rel="stylesheet" href="/statics/bootstrap/css/bootstrap.css">
<style>
.container{
margin-top: 100px;
}
.btn{
margin-top: 10px;
}
</style>
</head>
<body>
<h3>图书馆</h3>
<div class="container">
<div class="row">
<div class="col-md-6 col-md-offset-3">
<a href="/addbook/" class="btn btn-primary">添加书籍</a>
<table class="table table-striped table-bordered">
<thead>
<tr>
<th>书籍名称</th>
<th>价格</th>
<th>出版日期</th>
<th>出版社</th>
<th>删除操作</th>
<th>编辑操作</th>
</tr>
</thead>
<tbody>
{% for book in book_list %}
<tr>
<td>{{ book.title }}</td>
<td>{{ book.price }}</td>
<td>{{ book.pub_date|date:'Y-m-d' }}</td>
<td>{{ book.publish }}</td>
<td><a href="/book/{{ book.pk }}/delete" class="btn btn-danger">删除</a></td>
<td><a href="/book/{{ book.pk }}/change" class="btn btn-info">编辑</a></td>
</tr>
{% endfor %}
</tbody>
</table>
</div>

</body>

路由设置
from django.contrib import admin
from django.urls import path,re_path
from app01 import views
urlpatterns = [
path('admin/', admin.site.urls),
path('index/',views.index),
path('book/',views.book),
path('addbook/',views.addbook),
re_path(r"book/(\d+)/delete",views.delbook),
re_path(r"book/(\d+)/change",views.changebook),
# re_path(r"query",views.query)
]
视图设置：
from django.shortcuts import render,HttpResponse,redirect
from app01.models import Book
# Create your views here.
def book(request):
'''
查看图书馆书籍
:param request:
:return:
'''
book_list = Book.objects.all()
return render(request,'book.html',locals())
def addbook(request):
'''
添加书籍
:param request:
:return:
'''
if request.method=='POST':
title=request.POST.get('title')
price=request.POST.get('price')
date=request.POST.get('date')
publish=request.POST.get('publish')
Book.objects.create(title=title,price=price,pub_date=date,publish=publish,state=1)
return redirect('/book/')
return render(request,'addbook.html')
def delbook(request,id):
Book.objects.filter(id=id).delete()
return redirect('/book/')
def changebook(request,id):
'''
编辑书籍
:param request:
:param id:
:return:
'''
if request.method=='POST':
title = request.POST.get('title')
price = request.POST.get('price')
date = request.POST.get('date')
publish=request.POST.get('publish')
Book.objects.filter(id=id).update(title=title,price=price,pub_date=date,publish=publish)
return redirect('/book/')
return render(request,'changebook.html',locals())
模型设置
from django.db import models
# Create your models here.
class User(models.Model):
id = models.AutoField(primary_key=True,verbose_name='主键')
username = models.CharField(max_length=32,verbose_name='用户名')
# password = models.IntegerField()
password = models.CharField(verbose_name='密码',max_length=64)
class Book(models.Model):
id=models.AutoField(primary_key=True)
title=models.CharField(max_length=32)
state=models.BooleanField()
