Find or Create by ID

[sqlninja]

So I have a "micro" twitter system I maintain, where we store profiles, tweets, favorites, and followers for users in our db.
We store them because we crunch a lot of data together and it's easier than calling the real twitter API every time.

I've noticed when trying to do a find_or_create_by on profiles that if I use the id for the profile it always attempts an update because of the ORM#new? method checking for an id.

I have a search that allows users to search for other Twitter users, and I then attempt to save the new twitter profile using the id, this ensures if a screen_name changes we still get who we were hoping for.

Any insight on the best way to handle this?

I feel this can stem from this issue as well: #494

Hi @sqlninja as you point out, this is a side effect of new? not knowing if the resource exists or not. The only workaround that comes to mind is calling save_existing when find or find_by returns nil. Let us know if that helps. Meanwhile I'm going to close this as a duplicate of #494.
