So, back to the topic, which is, I believe, the testing of glom as it exists in the VL 7 testing repository.
And as to this issue, I think it probably is working fine as a program, but that I don't know how to connect it to the postgresql database (and therefore data is not saved).
I am now using kexi, as Chris530 suggested, and it is pretty slick. But it has some glitches and, from what I read, glom is probably a better database for my purposes, given my limited knowledge of linux databases.
Anyway, this is just a report. If anyone knows postgresql, I bet he or she could tell us how to connect glom to it. If not, I will try to figure it out as time permits.
