Rails - Mar 2006 - Help: Input of form 1 to hidden field in form 2?

Hi all I''m new to rails an i''m trying to build a step by step
form /
process to gather data. For example:
form one:
User enters a 8 digit number
the submit button points to form 2.

form two:
the 8 digit number from form one becomes a hidden field in form 2.

The problem I have is that the entire hash from form 1 is showing up in 
form two rather than just the input data.


example:

form 1:

<h1>Step 1</h1>

<%= start_form_tag :action => ''step2'' %>
  <%= render :partial => ''form1'' %>
  <%= submit_tag "Register Tag" %>
<%= end_form_tag %>

Here is the partial (form1):

<!--[form:tag]-->
<p>
<%= text_field ''tag'', ''tag'' 
%></p>
<!--[eoform:tag]-->



CONTROLLER:
  def step1
    @tag = Tag.new
    render :action => ''step1''
  end

  def step2
    @newtag = (@params[:tag])
    @tag = Tag.new
    render :action => ''step2''
  end


FORM 2:
...
<input id="tag" name="tag" type="hidden"
value="<%= @newtag %>" /></p>



RESULT:
If I submit 12345678 in form 1

I get "tag12345678" in form 2


FORM 2:
Source after Form 1 submit
<input id="tag" name="tag" type="hidden"
value="tag12345678" /></p>

I only want the digits 12345678.

you''re feeding the whole tag hash into @newtag. try changing in your  
controller:
> CONTROLLER:
>   def step1
>     @tag = Tag.new
>     render :action => ''step1''
>   end
>
>   def step2
>     @newtag = (@params[:tag])
       @newtag = (@params[:tag][:tag])
>     @tag = Tag.new
>     render :action => ''step2''
>   end
maybe you should change the name of your text_field name to something  
like tag[value]...tag[tag] is a bit confusing:

<%= text_field ''tag'', ''value''  %>

-tak.
