"gorm.io/gorm"
"log"
)
type Student struct {
gorm.Model
Name string
Age int
}
type StudentRepository struct {
gorm_generic.BaseRepository[Student]
db *gorm.DB
}
func NewStudentRepository(db *gorm.DB) *StudentRepository {
return &StudentRepository{
BaseRepository: gorm_generic.NewBaseRepository[Student](db),
db: db,
}
}
func (s *StudentRepository) CustomQuery(ctx context.Context) (*Student, error) {
var m Student
err := gorm_generic.FromContext(ctx, s.db).First(&m, 1).Error
if err != nil {
return nil, err
}
return &m, nil
}
func main() {
db, err := gorm.Open(nil)
if err != nil {
log.Fatalln(err)
}
r := NewStudentRepository(db)
students := []*Student{
{
Name: "test1",
Age: 18,
},
{
Name: "test2",
Age: 18,
},
}
r.BatchInsert(context.TODO(), students)
r.FindById(context.TODO(), 1)
r.FindByIdsWithDeleted(context.TODO(), 1)
r.CustomQuery(context.TODO())
}
