Override created_on column name

We are using Rails for a project that must integrate with a legacy
database. Is there a way to get Rails to automatically set the
timestamp
for a column named something other created_on or updated_on ?

Also, how does one manipulate the size of the database connection pool?

Use Active Record callbacks to set their values to Time.now in
before_create/save.

pool?

Database connections are opened one per Rails instance (whether
FastCGI, Mongrel, or otherwise.)

Hello Jeremy,

Use Active Record callbacks to set their values to Time.now in
before_create/save.

Thanks. I just read upon this in “Agile Web Dev. w/ Rails”.

By “Rails Instance”, you mean all requests must share the same
connection,
or each request gets it’s own connection?

Rails requests are processed serially (one request at a time, single
file) so only one connection is required. By ‘Rails instance’ I mean
a dispatch.fcgi/Mongrel/webrick/etc process. Rails ‘scales’ by
adding more processes, so if you’ve set up lighttpd with 4 fastcgi,
you’ll have 4 database connections.
