Rails - Dec 2006 - Two form fields, same name. How to get the data?

Hi there,

I have a form with two fields that have the same name.  I didn''t
generate the names, Rails did.  I''m using two ajax auto completers.

On other webservers, if I had two fields with like names, I would get a
comma delimited string of the two values.  Rails however is only
returning the first value.

How can I retrieve both values?

Or 

How can I specify the name of an ajax auto completer?

Thanks,

Bry

Ok, I figured out that I need to put :index => 1 and :index => 2 on my
fields.

Now I need to know how to read the values in my controller?  I can''t
just do a simple params[:fieldname]

These are my two form fields:

name="tag[1][tag]"
name="tag[2][tag]"

how do I retrieve the values?

Thanks,

Bry

I think you can use params[:tag][:1].

place debug(params) in your view to see how the feilds are being passed.

Might want to add a debug statement to the view to see what is in
params, I don''t know how rails handles this.  FYI browsers send the
values null separated, then it''s up to the cgi library how to deal
with them.

I figured out the solution.  I needed to do this:

params[:tag][''1''][''tag'']

However, since I added the indexes to my auto_completes the ajax auto
complete no longer works.  So now I''m stumped again.
