Gorm How to get LastInsertId when Create with map?

Your Question

The docs says now it is able to Create() from map

db.Model(&User{}).Create(map[string]interface{}{"Name": "jinzhu", "Age": 18})

But how can I get LastInsertId? I try put an id key in the map, but after created, the id is still nil. So how can I get LastInsertId?

I know I can use User{} model to insert data and get LastInsertId, but there is some reason that I have to insert with a map, and get the LastInsertedId.

The document you expected this should be explained

Add an example of getting LastInsertId after create with map.

Expected answer

Get LastInsertId after Create() with map

When you create the User struct embedded the gorm.Model

 type User struct{
   gorm.Model
   Name string
   Age int
}

You would got a primary key ID by default. After the new user is committed by gorm, the user has been injected with ID, CreateAt, UpdateAt and DeleteAt attributes, So. You can change the code as following:

   user := &User{"Name": "jinzhu", "Age": 18}
  db.Create(user)
  fmt.Printf("User id: %s", user.ID)
