Hello.

I have entity with unique field. I am trying to save passing this unique key. After 2nd save call, I get “duplicate key”, beacuse typeorm is inserting instead of updating, beacuse typeorm does not check for unique key, but primary key.

Unique key should be considered in save, when primary key is not provided.

Also wondering, any progress yet?

The upsert is done by using columns that identify the data, the primary key. As I know a constraint “Unique key” have not for purpose to identify a row on your table. If it’s the case that mean your column have to be include on your primary key.

To apply an upsert like you expect using the fact that there is a conflict is not a common case and should be handle differently than using Save.
