I've inherited an existing model and added 3 fields to it. Wrote XML view for these fields and everything worked. But I forgot to add another field in the same inherited model, so when I define another field it gives me an error:

ProgrammingError: column res_partner.street3 does not exist
LINE 1: ...,"res_partner"."purchase_warn" as "purchase_warn","res_partn...
                                                             ^
HINT:  Perhaps you meant to reference the column "res_partner.street" or the column "res_partner.street2".

Any ideas why it's happening? It feels like I can't add any fields after I've defined my model and ran the server.
