I am trying to build a generic CrudRepository struct using Gorm for my api. I know generics are coming to GoLang in version 2 but I try to build this lib using reflection or any other lib.
In my CrudRepository:
func (repository *BaseRepository) find(result interface{}, pageSize int, page int) error {
if page < 1 {
return errors.ExceedsMinimumInt("page", "", 0, true, nil)
}
offset := (page - 1) * pageSize
ent := reflect.Zero(reflect.TypeOf(result))
repository.db = repository.db.Limit(pageSize).Offset(offset)
err := repository.db.Find(&ent).Error
result = ent
if err != nil {
return err
}
return nil
}
And calling this method sth like:
func List(){
var entityList []MyEntity
find(entityList, 1, 10)
}
I think, I cannot pass any interface reference into Gorm.db.Find() method Is there any other way to succeed?
