Rails - Mar 2010 - Post Methods

Hello!, I''m a RoR begginer, i need it to make a web interface for a
bigger project that i''m developing in Ruby, but i don''t know
how to do
the next:

I want to read a config file of my main program (a normal conf file),
and be able to change some values.
I take all the names and values pf my config file correctly via a ruby
function, to change the values i think in a form which has a lot of
inputs named like the vars i want to change, and send the new value.
My post command it''s correct for me, it contains the data i want
(something like [name]value[name]value....) , but i don''t know how i
can access to the post variable to work with this data in Ruby ( i
need to write a file [name] \n value .....)
The code for my form its:

<% form_for :variable , :legend => "Personal info", :url =>
{:action
=> :save_post} do |$dataform| %>
....#Read my file .....
....
Name: <%=text_field_tag("#{var_name}", "#{value}", :size
=> 20)%> </p>
<%=  submit_tag "Change Config File", :class =>
"submit" %>

so, how can i access to the post variable?

Thanks!

Within your controller action you can do:

params[:my_param_name]

Assuming you''ve done something like PHP before, it''s the
equivalent to
PHP''s:

$_POST["my_param_name"]

Cheers,
