Types

type BelongsTo 

type BelongsTo[T model.Model] struct {
	// contains filtered or unexported fields
}

BelongsTo represents a belongs to relationship on a model. The parent model with a BelongsTo property will have a column referencing another tables primary key. For example if model Foo had a BelongsTo[*Bar] property the foos table would have a foos.bar_id column related to the bars.id column. Struct tags can be used to change the column names if they don't follow the default naming convention. The column on the parent model can be set with a foreign tag and the column on the related model can be set with an owner tag.

Tags:

  • owner: parent model
  • foreign: related model
Example 
sqlite.UseSQLite()
type Bar struct {
	model.BaseModel
	ID   int    `db:"id,autoincrement,primary"`
	Name string `db:"name"`
}

type Foo struct {
	model.BaseModel
	ID    int `db:"id,autoincrement,primary"`
	BarID int `db:"bar_id"`
	Bar   *builder.BelongsTo[*Bar]
}

db := sqlx.MustOpen("sqlite3", ":memory:")
defer db.Close()

createFoo, err := migrate.CreateFromModel(&Foo{})
check(err)
err = createFoo.Run(context.Background(), db)
check(err)
createBar, err := migrate.CreateFromModel(&Bar{})
check(err)
err = createBar.Run(context.Background(), db)
check(err)

foo := &Foo{BarID: 1}
err = model.Save(db, foo)
check(err)
bar := &Bar{ID: 1, Name: "bar name"}
err = model.Save(db, bar)
check(err)

err = builder.Load(db, foo, "Bar")
check(err)
relatedBar, _ := foo.Bar.Value()

fmt.Println(relatedBar.Name)

Output:
