Hi guru's out there,

Im happilly coding my first rails app, and all goes well. I find myself
manually coding in a particular field all the time (company_id), that relates
the contact to a company. The total coding of this form seems somewhat much.
Could somebody tell me what Rails power I'm possibly missing and stuborn as I
am trying to do myself?

I was wondering if the first part of the form can simply be put in the loop
somehow and still be a dropdownlist. So if anybody wants to shoot, here's the
form code:

<%= start_form_tag :action => 'update_contact', :id => @contact %>
<table border="0" cellpadding="3"
cellpadding="0">
<tr>
  <th>Field</th><th>Contents</th>
  </tr>
### First part - My 'manual' coded stuff
<%  odd_or_even = 0 %>
<tr class="ListLine<%= odd_or_even
%>"><td>Company</td>
  <td>
  <select name="contact[company_id]">
  <% @companies.each do |company| %>
    <option value="<%= company.id %>">
      <%= company.name %>
    </option>
  <% end %>
  </select>
  </td></tr>
### The cool dynamic part that shows the rest
<%
  odd_or_even = 0
  for column in Contact.content_columns
  odd_or_even = 1 - odd_or_even
%>
  <tr class="ListLine<%= odd_or_even %>">
  <td><%= column.human_name %>:</td>
  <td><%= text_field 'contact', column.name  %></td>
  </tr>
<% end %>
</table>
<input type="submit" value="Save" />
<%= end_form_tag %>

Thanx a lot guys!

Regards,

Gerard.

you can replace above with following:
( if @companies are extracted from Company class (companies table) )

<%= @companies = Company.find(:all)
    collection_select(:contact, :company_id, @companies,
                      :id, :name )
%>

Hiroshi,

Great thanx. That worked.

But my more pressing question: Is it necessary to have the dropdownlist
generated seperately from the full field generation loop?

Regards,

Gerard.

You can also use the 'cycle' helper to do the table striping.

Do something like this...

<tr class="ListLine<%= cycle("0","1")
%>">

Kevin,

I did not digest the helper chapter yet in the Agile webdev book, but I asume
you mean create a shareable function called cycle, and remove the code from
the view?

Grtz n Thanx

Gerard.

'cycle' is a predefined helper for doing table striping.

See

Kevin,

Thanx! That'll be a nice cleanup in my views. Will take a look at that .. :-)

And best wishes to you to!

(And ofcourse to all coders the world over!)
