[Question about avram] Update the table attribute with same value in the SaveOpeation is noop.

[zw963]

e.g. foo record name's value is 1, when update use same value like this: SaveFoo.update!(foo, name: 1), there is no database update SQL executed.

Is this is a feature of avram, or postgres builtin?

Thanks

Yes, that is how Aram is designed to work. If no attribute changes, the database query is not run.
