hello everybody
I want to pass user_id to another controller, => category
this is my code
<%form_for :user, @user, :url=>{ :action =>"index",
:controller =>
"categories"} do |f| %>
<%= select(:category, :user_id, @users.map{|p| [p.name, p.id] }) %>
<%= submit_tag "Ir" %>
<% end %>
when I push submit bottom form_for generate the object params with 3
paramaters
{"action" => "index",
"controller" => "categories",
but I don´t know which is the third parameter}
perhaps this?? I don´t know
"user"=> {name=> "bla bla", id=>"bla
bla"}
In my category controller in the method index I do this
@valor = params[:category]
render :text => @valor
the browser writte this
user_id1; if i select one
user_id2; if I select two
etc...
if I want take de user_id, how do it?
my select and my form_for are well???
thank you

If you look at the HTML source code of the page your form is on, you''ll see that the selection drop box form field is named "category[user_id]". Other form fields built with the helpers against the category model will be named similarly - "category[fieldname]". The result when the form is submitted is that all the input fields are put into a hash {''user_id'' => 3, ''name'' => ''joe blow''}, which is then added to the overall params hash with a key of :category, as if this had been done... params{:action => ''index'', :controller => ''category'', :category => {:user_id => n}} What you are seeing here:> user_id1; if i select one > user_id2; if I select two...is Rails default rendering of the hash params[:category]. You are seeing the hash {''user_id'' => 1} or {''user_id'' => 2} flattened out for display. If you were to, instead: render :text => @valor.inspect You''ll see the contents of the params[:category] hash displayed a little more intelligently. So, bottom line is, when you see this: user_id1; if i select one then params[:category][''user_id''] is equal to 1. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Sorry - typo up there... where I wrote:
params{:action => ''index'', :controller =>
''category'', :category =>
{:user_id => n}}
I meant to write:
params = {:action => ''index'', :controller =>
''category'', :category =>
{:user_id => n}}
