Change Log


Breaking Changes

  • gorm.Open return type *gorm.DB instead of gorm.DB

  • Updating will only update changed fields

    Most applications won't be affected, only when you are changing updating values in callbacks like BeforeSave, BeforeUpdate, you should use scope.SetColumn then, for example:

    func (user *User) BeforeUpdate(scope *gorm.Scope) {
      if pw, err := bcrypt.GenerateFromPassword(user.Password, 0); err == nil {
        scope.SetColumn("EncryptedPassword", pw)
        // user.EncryptedPassword = pw  // doesn't work, won't including EncryptedPassword field when updating
  • Soft Delete's default querying scope will only check deleted_at IS NULL

    Before it will check deleted_at less than 0001-01-02 also to exclude blank time, like:

    SELECT * FROM users WHERE deleted_at IS NULL OR deleted_at <= '0001-01-02'

    But it is not necessary if you are using type *time.Time for your model's DeletedAt, which has been used by gorm.Model, so below SQl is enough

    SELECT * FROM users WHERE deleted_at IS NULL

    So if you are using gorm.Model, then you are good, nothing need to be change, just make sure all records having blank time for deleted_at set to NULL, sample migrate script:

import (

func main() {
  var models = []interface{}{&User{}, &Image{}}
  for _, model := range models {
    db.Unscoped().Model(model).Where("deleted_at < ?", now.MustParse("0001-01-02")).Update("deleted_at", gorm.Expr("NULL"))
  • New ToDBName logic

    Before when GORM convert Struct, Field's name to db name, only those common initialisms from golint like HTTP, URI are special handled.

    So field HTTP's db name will be http not h_t_t_p, but some other initialisms like SKU that not in golint, it's db name will be s_k_u, which looks ugly, this release fixed this, any upper case initialisms should be converted correctly.

    If your applications using some upper case initialisms which doesn't exist in golint, you need to overwrite default column name with tag, like gorm:"column:s_k_u", or alert your database's column name according to new logic

  • Error RecordNotFound has been renamed to ErrRecordNotFound

  • mssql driver has been moved out from default drivers, import it with import _ ""

  • Hstore has been moved to package
