form_for and Multiple Models Being Saved

Howdy Folks,

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.

Something like this:

<%= form.text_field :event_city, :index => @event_date.id %>

But, for an unsaved item, @event_date.id will be nil so what do folks use to
handle this?

Any help very much appreciated.

Cheers,
Hunter

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

You''d pass :index if you had multiple event_city for a single record.
Sounds
like you don''t need it at all.

production server on nonstandard port, "unable to connect to host" error

I have a very weird problem where no one can connect to my server  
("foo.com"), even though DNS is working.

I''m running my rails app on port 8000 using this command:

# ./script/server webrick --port=8000 --environment=production
=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:8000
=> Ctrl-C to shutdown server; call with --help for options
[2006-09-27 23:06:42] INFO  WEBrick 1.3.1
[2006-09-27 23:06:42] INFO  ruby 1.8.4 (2005-12-24) [i386-linux]
[2006-09-27 23:06:42] INFO  WEBrick::HTTPServer#start: pid=1345  
port=8000


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!

Thanks everyone,
-Jason

Re: production server on nonstandard port, "unable to connect to host" error

You were right Vish. We needed to open port 8000 in iptables. Works  
fine now.

Thanks!

migrate production db, not development?

I want "rake migrate" to act on my production db, not the development
one; do I just change database.yml from this:

development:
   database: myproject_development


...to this?

development:
   database: myproject_production


Thanks!

No.  Leave your database file as-is.  Run this instead:

$ rake migrate RAILS_ENV=production
