## Struct Field 类型与数据库的对应
## 模型字段与数据库类型的对应
现在 orm 支持下面的字段形式
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。
| go type | field type | mysql type
| :--- | :--- | :---
| bool | TypeBooleanField | tinyint
| string | TypeCharField | varchar
| string | TypeTextField | longtext
| time.Time | TypeDateField | date
| time.TIme | TypeDateTimeField | datetime
| int16 |TypeSmallIntegerField | int(4)
| int, int32 |TypeIntegerField | int(11)
| int64 |TypeBigIntegerField | bigint(20)
| uint, uint16 |TypePositiveSmallIntegerField | int(4) unsigned
| uint32 |TypePositiveIntegerField | int(11) unsigned
| uint64 |TypePositiveBigIntegerField | bigint(20) unsigned
| float32, float64 | TypeFloatField | double
| float32, float64 | TypeDecimalField | double(digits, decimals)
默认所有的字段都是 **NOT NULL**
关系型的字段，其字段类型取决于对应的主键。
#### MySQL
| go |mysql
| :--- | :---
| bool | bool
| string - 设置 size 时 | varchar(size)
| string | longtext
| time.Time - 设置 type 为 date 时 | date

| uint16 | integer CHECK("column" >= 0)
| uint32 | bigint CHECK("column" >= 0)
| uint64 | bigint CHECK("column" >= 0)
| float32 | 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。
