More questions about RoR!

is there something about garbage collection a rails application needs to
worry about? if models(i.e model.new) are being created eveytime a user
visits a page, does that memory get ‘held up’ some place? does it need
to be freed?

if there are multiple requests/updates to a table from multiple users,
does rails handle mutex/data protection? or is this not an issue?

thanks

No, Ruby does garbage collection for you.

Active Record supports both optimistic and pessimistic locking.

Add a lock_version integer not nil default 0 column to your table to
automatically enable optimistic locking.

Sorry for the off-topic comment, but is this group moderated or
something?

I tried to start a new topic several times today, and though a long
time has passed I don’t see that the topic has been published to the
group.

Anyone experiencing similar difficulties?
