feeling shoehorned: using joins in gorm - orm

Question

Disclaimer: this is my first time using an ORM, and my SQL might be a bit rusty.
I have an application with users, songs, and I want to count and display how many times each song has been played by a given user. I know how to do it with SQL, but I'm failing at translating this to GORM. It goes like this:
package main
import (
"github.com/jinzhu/gorm"
_ "github.com/jinzhu/gorm/dialects/sqlite"
)
type User struct {
ID int `gorm:"primary_key"`
Listened []Listen
}
type Song struct {
ID int `gorm:"primary_key"`
Title string
Listened []Listen
}
type Listen struct {
UserID int `gorm:"primary_key;auto_increment:false"`
SongID int `gorm:"primary_key;auto_increment:false"`
Count int
}
Then, let's add some data
func main() {
db, err := gorm.Open("sqlite3", "test.db")
if err != nil {
panic(err)
}
defer db.Close()
db.DropTableIfExists(&User{}, &Song{}, &Listen{})
db.CreateTable(&User{}, &Song{}, &Listen{})
db.Save(&User{ID: 1})
db.Save(&User{ID: 2})
db.Save(&Song{ID: 1, Title: "oh yeah"})
db.Save(&Song{ID: 2, Title: "greatest song"})
db.Save(&Song{ID: 3, Title: "bestest song"})
db.Save(&Listen{UserID: 1, SongID: 1, Count: 7})
db.Save(&Listen{UserID: 1, SongID: 2, Count: 23})
db.Save(&Listen{UserID: 2, SongID: 2, Count: 13})
db.Save(&Listen{UserID: 2, SongID: 3, Count: 10})
// do something here
}
Now, as I said I want to list how many times a user has played each song of the database. After scratching my head a little I came to this:
sqlite> select songs.id, l.count from songs
...> left join (select song_id, count from listens where user_id = 1) as l
...> on songs.id = l.song_id;
id count
---------- ----------
1 7
2 23
3
... and here I am. I just don't understand how I can express that with GORM method chains. Or should I just give up and run a raw sql query?

Answer 1

In the end I found how to do it:
db.Table("songs").
Select("songs.id, listens.count").
Joins("left join (select * from listens where user_id = ?) as listens on songs.id = listens.song_id", 1).
Find(&rs)

Answer 2

This query probably will work also. I hope it's helpful.
if err := db.Table("listens").Select("songs.id, listens.count").
Joins("JOIN songs on listens.song_id = songs.id").Where("user_id = ?",
1).Find(&rs).Error; err != nil {
fmt.Prinln(err)
}
