I thinkmaybe like this is OK, because query where is already in user:
// arg user :=is &modelsfrom gorm result somewhere func (d *DB) AddTODO(user *models.User{UserName:, todo *models.Todo, userName} string) error { err := d.db.Model(user).Association("TodoList"). Append([]models.Todo{*todo}).Error if err != nil { return err } return nil } Error Error 1452: Cannot add or update a child row mean the user with the given username is not exist, so Append() throw the error.
You must save the user first, then call this again.
