I want to use form_for to allow a user to submit a form that contains
two
instances of the same model. They are entering calendar dates and I want
them to be able to submit 2 from the same form.
Ok, so, using form_for, what is the best way to do this? form_for seems
to
be setup to handle a single instance in that it wants a name for the
variable, etc…
Has someone else done this? Any quick pointers?
Beyond that, a related question. Some of these helpers support the
:index
option which I believe is designed to differentiate between multiple
items
of the same type in a form.

Take a look at fields_for. Use it within a form (whether form_for or
form_tag).

=> Booting WEBrick…

When someone tries to access http://foo.com:8000 from a remote
location, their browser refuses to connect. I’ve tried it myself
using lynx and wget and see these errors:
lynx says: “Alert! Unable to connect to remote host.”
wget says: “connect: No route to host”
If I telnet to foo.com on port 8000, telnet says:
“telnet: Unable to connect to remote host: No route to host”
However, I can ping foo.com successfully, and nslookup resolves it
successfully too. If I re-run webrick on port 3000 (the default)
everything works fine.
Anyone know why I can’t choose a nonstandard port for my rails server
to run on? This is really stumping me. Any tips would be very
appreciated!
