Composite Primary Key

Set multiple fields as primary key creates composite primary key, for example:

type Product struct {
ID string `gorm:"primaryKey"`
LanguageCode string `gorm:"primaryKey"`
Code string
Name string
}

Note integer PrioritizedPrimaryField enables AutoIncrement by default, to disable it, you need to turn off autoIncrement for the int fields:

type Product struct {
CategoryID uint64 `gorm:"primaryKey;autoIncrement:false"`
TypeID uint64 `gorm:"primaryKey;autoIncrement:false"`
}
