我尝试用 gorm 创建 mysql 事务,这是代码:
type Game struct {
Images []string
}
game := Game{Images: []string{"1.png", "2.png"}}
db := Database()
tx := db.Begin()
if err := tx.Create(&game).Error; err != nil {
tx.Rollback()
return errors.New("Cannot add game")
}
tx.Commit()
但我收到报错如下:(sql: converting argument $1 type: unsupported type []string, a slice of string)
我知道 mysql 不支持这种类型,但是我能用某种方式解决这个问题吗? 我想我可以把字体改成Json.rawmessage,但我认为这是错误的方式。

If you want a list of something in MySql, you have two options
gorm supports joins through something it calls associations. In this case, you have a has many association (http://doc.gorm.io/associations.html#has-many).
An example of how you might do this is:
type Game struct {
gorm.Model
GameImages []GameImage
}
type GameImage struct {
gorm.Model
Name string
}
db.Model(&game).Related(&gameImages)
这个问题我也遇到了,可以先转换成JSON格式,然后再通过自定义JSON类型使得gorm库可以支持,我写了一篇博客详细介绍了该过程,可以移步: golang-gorm库不支持[]string类型问题的解决方法 https://blog.csdn.net/weixin_43811340/article/details/119455488?spm=1001.2014.3001.5502
