Sqlmock + Gorm 失败并显示错误“不支持的数据类型：&[]”

如何解决Sqlmock + Gorm 失败并显示错误“不支持的数据类型：&[]”

我尝试用 sqlmock 测试 gorm 的东西。

我的模型看起来像：

type Worker struct {
  Model
  NetworkAddress string
  Name           string
  Version        string
  Available      bool
  Services       []Service `gorm:"foreignKey:WorkerId;references:Id"`
}

我收到以下错误：

unsupported data type: &[]: Table not set,please set it like: db.Model(&user) or db.Table("users")

测试：

db,mock := createMock(t)
repo = db
row := sqlmock.NewRows([]string{"id","network_address","version","name"}).AddRow("1","test","1.0","test")
mock.ExpectQuery(regexp.QuoteMeta("SELECT * FROM `workers` WHERE `workers`.`id` = ? AND `workers`.`deleted_at` IS NULL ORDER BY `workers`.`id` LIMIT 1")).
    WithArgs(1).
    WillReturnRows(row)
db.Con.Table("Services")
worker,err := FindWorkerByConds(1)
if err != nil {
    t.Errorf("expected query to be executred,got error %s",err)
}
if worker.Name != "test" {
    t.Error("expected name to be test")
}

功能：

var (
    worker  *models.Worker
    tx      *gorm.DB
)
worker = &models.Worker{}
// use builder to load preload conditions
tx = repo.Build().Preload("Services").First(worker,conds)
return worker,tx.Error

Build 只是一个返回 *gorm.DB

的助手

运行示例按预期工作，但尝试对其进行单元测试失败。
