|
||
|
||

|
||
|
||

|
||
- 表名：`book_author`
|
||
- 模型：`model/book/book_author.go`
|
||
- 迁移接入：`initialize/gorm_biz.go`

|
||
|
||
## 建议 SQL
|
||
|
||
> 以下 SQL 以当前项目 PostgreSQL 为准，主要表达字段、约束和索引语义；实际落库以 `GORM Model` 和 `initialize/gorm_biz.go` 为准。
|
||
|
||
```sql
|
||
CREATE TABLE book_author (
|
||
id bigserial PRIMARY KEY,
|
||
created_at timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
|
||
updated_at timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
|
||
name varchar(128) NOT NULL,
|
||
author_status varchar(32) NOT NULL DEFAULT 'enabled',
|
||
intro text,
|
||
cover_url varchar(500)
|
||
);
|
||
|
||
COMMENT ON TABLE book_author IS '书籍作者表';
|
||
COMMENT ON COLUMN book_author.id IS '主键';
|
||
COMMENT ON COLUMN book_author.created_at IS '创建时间';
|
||
COMMENT ON COLUMN book_author.updated_at IS '更新时间';
|
||
COMMENT ON COLUMN book_author.name IS '作者名称';
|
||
COMMENT ON COLUMN book_author.author_status IS '作者状态字典值，对应 book_author_status';
|
||
COMMENT ON COLUMN book_author.intro IS '作者简介';
|
||
COMMENT ON COLUMN book_author.cover_url IS '作者封面图片 URL';
|
||
|
||
CREATE UNIQUE INDEX uk_book_author_name ON book_author (name);
|
||
CREATE INDEX idx_book_author_author_status ON book_author (author_status);
|
