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 %>
| Field |
Contents |
### First part - My 'manual' coded stuff
<% odd_or_even = 0 %>
| Company |
<% @companies.each do |company| %>
<%= company.name %>
<% end %>
|
### 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
%>
| <%= column.human_name %>: |
<%= text_field 'contact', column.name %> |
<% end %>
<%= 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.

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

You can also use the ‘cycle’ helper to do the table striping.
Do something like this…

‘cycle’ is a predefined helper for doing table striping.
See
http://api.rubyonrails.com/classes/ActionView/Helpers/TextHelper.html#M000430

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!)
