分析
- 一本书 可以由多个作者编著
- 一本书只能由一个出版社出版
- 一个作者可以写多本书
- 每个作者有自己的简介
对应关系:
- Author-Book # 多对多
- Publish-Book # 一对多
- Author-AuhtorDetail # 一对一
如何创建:
- 多对多:ManyToManyField
- 一对多:ForeignKey
- 一对一:OneToOneField
注意:创建一对多表的时候,ForeignKey建在多的那一方。另外两个随意建在哪一方。
目录结构
配置 settings.py
注册app:INSTALLED_APPS 项中添加bms
配置静态文件:
STATICFILES_DIRS = [ os.path.join(BASE_DIR, ‘bms‘, ‘static‘) ]
配置模板:
TEMPLATES中添加:
‘DIRS‘: [os.path.join(BASE_DIR, ‘templates‘)]
配置路由分发
DjangoBMS.urls.py
from django.conf.urls import url,include from django.contrib import admin urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘^bms/‘, include(‘bms.urls‘)), ]
配置母模
<!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no"> <title>Title</title> <link rel="stylesheet" href="/static/plugins/bootstrap/css/bootstrap.min.css"> {% block page-css %} {% endblock %} <body> {% block page-main %} {% endblock %} <script src="/static/js/jquery-3.2.1.min.js"></script> <script src="/static/plugins/bootstrap/js/bootstrap.min.js"></script> {% block page-js %} {% endblock %} </body> </html>
layout
创建数据库表结构
bms.models.py
from django.db import models class Publish(models.Model): # 出版社 name = models.CharField(max_length=32) email = models.EmailField() class AuhtorDetail(models.Model): # 作者简介 addr = models.CharField(max_length=32) email = models.EmailField() class Author(models.Model): # 作者 name = models.CharField(max_length=32) age = models.IntegerField() detail = models.OneToOneField(‘AuhtorDetail‘) class Book(models.Model): # 书籍 title = models.CharField(max_length=32) publishDate = models.DateField() price = models.DecimalField(max_digits=5, decimal_places=2) # 最大 999.99 publish = models.ForeignKey(‘Publish‘) # 一对多 authors = models.ManyToManyField(‘Author‘) # 多对多
生成表命令:
python manange.py makemigrations
python manage.py migrate
