Features

  • accept extend option to allow extending existing models (48b80e4)

1.1.0 (2022-02-28)

Features

  • Added MSSQL support as a 4th fully supported DBMS.
  • Added SetColumn("col_name", "upper(?)", "hello") in addition to Set("col_name = upper(?)", "hello") which works for all 4 supported DBMS.
  • improve nil ptr values handling (b398e6b)

Breaking changes

  • Bun no longer automatically marks some fields like ID int64 as pk and autoincrement. You need to manually add those options:
type Model struct {
-	 ID int64
+	 ID int64 `bun:",pk,autoincrement"`
}

Bun v1.0.25 prints warnings for models with missing options so you are recommended to upgrade to v1.0.24 before upgrading to v1.1.x.

  • Also, Bun no longer adds nullzero option to soft_delete fields.

  • Removed nopk and allowzero options.

Bug Fixes

  • append slice values (4a65129)
  • check for nils when appending driver.Value (7bb1640)
  • cleanup soft deletes for mssql (e72e2c5)
  • dbfixture: apply cascade option. Fixes #447 (d32d988)
  • create table WithForeignKey() and has-many relation (3cf5649)
  • do not emit m2m relations in WithForeignKeys() (56c8c5e)
  • accept dest in select queries (33b5b6f)

1.0.25 (2022-02-22)

Bug Fixes

Deprecated

In the coming v1.1.x release, Bun will stop automatically adding ,pk,autoincrement options on ID int64/int32 fields. This version (v1.0.23) only prints a warning when it encounters such fields, but the code will continue working as before.

To fix warnings, add missing options:

type Model struct {
-	 ID int64
+	 ID int64 `bun:",pk,autoincrement"`
}

To silence warnings:

bun.SetWarnLogger(log.New(ioutil.Discard, "", log.LstdFlags))

Bun will also print a warning on soft delete fields without a ,nullzero option. You can fix the warning by adding missing ,nullzero or ,allowzero options.

In v1.1.x, such options as ,nopk and ,allowzero will not be necessary and will be removed.

Bug Fixes

  • fix missing autoincrement warning (3bc9c72)
  • append slice values (4a65129)
