    user := User{Name: "jinzhu", Age: 5}
    toy := Toy{Name: "jinzhu", OwnerID: "test"}

    DB.Create(&user)
    DB.Create(&toy)

    var result User

    DB = DB.Where("name = ?", "jinzhu")

    if err := DB.First(&result, "age = ?", 5).Error; err != nil {
        t.Errorf("Failed, got error: %v", err)
    }

    var ttoy Toy
    if err := DB.First(&ttoy, "owner_id = ?", "test").Error; err != nil {
        t.Errorf("Failed, got error: %v", err)
    }
