在此列出 ORM 推荐的对应数据库类型,自动建表功能也会以此为标准。
默认所有的字段都是 NOT NULL
MySQL
| go | mysql |
|---|---|
| int, int32 - 设置 auto 或者名称为 Id 时 | integer AUTO_INCREMENT |
| int64 - 设置 auto 或者名称为 Id 时 | bigint AUTO_INCREMENT |
| uint, uint32 - 设置 auto 或者名称为 Id 时 | integer unsigned AUTO_INCREMENT |
| uint64 - 设置 auto 或者名称为 Id 时 | bigint unsigned AUTO_INCREMENT |
| bool | bool |
| string - 默认为 size 255 | varchar(size) |
| string - 设置 type(text) 时 | longtext |
| time.Time - 设置 type 为 date 时 | date |
| time.Time | datetime |
| byte | tinyint unsigned |
| rune | integer |
| int | integer |
| int8 | tinyint |

| uint8 | tinyint unsigned |
| uint16 | smallint unsigned |
| uint32 | integer unsigned |
| uint64 | bigint unsigned |
| float32 | double precision |
| float64 | double precision |
| float64 - 设置 digits, decimals 时 | numeric(digits, decimals) |

关系型字段
其字段类型取决于对应的主键。
- RelForeignKey
- RelOneToOne
- RelManyToMany
- RelReverseOne
- RelReverseMany
