图书管理系统之书籍的增删改查
书籍表结构设计
1. id title 出版社_id
2. SQL
create table book (
id int primary key auto_increment,
title varchar(30) not null,
press_id int not null,
constraint fk_press foreign key(press_id) references press(id)
on delete cascade
on update cascade
)
3. ORM外键
press = models.ForignKey(to='Press', on_delete=models.CASCADE)
书籍的增删改查
1. 查询
1. book_obj.press --> ORM层面封装的，返回的是和我这本书关联的出版社对象
2. book_obj.press_id --> 数据库中真正存在的字段，保存的是和我关联的出版社id值
2. 增加
1. 用select标签把已经存在的出版社在页面上展示出来
让用户去选择
使用的是：模板语言的for循环
<select name="press_id" class="form-control">
{% for press in press_data %}
<option value="{{ press.id }}">{{ press.name }}</option>
{% endfor %}
</select>
3. 删除
类名.objects.filter(id=).delete()
补充一个3秒钟之后跳转到指定页面的操作
1. location.href
2. setTimeout()
3. setinterval()
4. 编辑
obj = 类名.objects.get(id='')
obj.name = '新值' --> 修改对象的属性（修改数据行某个字段的值）
obj.save() --> 把修改同步到数据库
用select标签展示默认的出版社
<select name="press_id" class="form-control">
{% for press in press_list %}
<option value="{{ press.id }}">{{ press.name }}</option>
{% endfor %}
</select>

注意
ORM变更表结构
ORM修改表结构的时候，执行 python3 manager.py makemigration 时候出来俩选项
1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
2) Quit, and let me add a default in models.py
为什么?
给数据库中已经存在的表添加另外一个字段，这个字段既没有默认值也不能为空
ORM就不知道数据库中已经存在的数据该怎么处理这个字段
选项1 是直接在 makemigration跳转到相应的界面自定义默认值, 然后直接执行 migrate命令完成数据库表结构的变更
manage.py@bookmanager > makemigrations
bash -cl "/usr/local/bin/python3.6 /Applications/PyCharm.app/Contents/helpers/pycharm/django_manage.py makemigrations /Users/cjw/Desktop/bookmanager"
Tracking file by folder pattern: migrations
You are trying to add a non-nullable field 'price' to book without a default; we can't do that (the database needs something to populate existing rows).
Please select a fix:
1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
2) Quit, and let me add a default in models.py
Select an option: 1
Please enter the default value now, as valid Python
The datetime and django.utils.timezone modules are available, so you can do e.g. timezone.now
Type 'exit' to exit this prompt
>>>
选项2 则是退出 makemigration界面, 去models.py中定义相关的字段属性, 完成后回来重新执行 makemigration, 然后再执行migrate
图书管理系统之作者的增删改查
作者表结构设计
1. SQL版
-- 创建作者表
create table author(
id int primary key auto_increment,
name varchar(32) not null
);
-- 创建作者和书的关系表
create table author2book(
id int primary key auto_increment,
author_id int not null,
book_id int not null,
constraint fk_author foreign key (author_id) references author(id) on delete cascade on update cascade,
constraint fk_book foreign key (book_id) references book(id) on delete cascade on update cascade
);
2. ORM版
1. 第一版：
自己创建第三张表
2. 第二版
让ORM帮我们创建第三张表
models.ManyToManyField()
作者表与书籍表的增删改查
author_obj = Author.objects.all()
1. 查询
author_obj.books --> 得到的只是一个关联关系，并不能拿到数据
author_obj.books.all() --> 得到和我这个作者关联的所有书籍对象列表
2. 添加
author_obj.books.add() --> 对author_obj这个对象追加外键字段books的值, 传入的值是单列数据类型
author_obj.books.set() --> 对author_obj这个对象重新添加外键字段books的值, 传入的值是列表或元组
3. 删除
Author.objects.filter(id=delete_id).delete()
3. 编辑
author_obj.name = author_name
author_obj.save()
author_obj.books.set(book_ids)
