Rails - Dec 2005 - Sort or Order a <Select> box.

Evening folks,

I''m new to RoR, and have found some very useful info on this site, 
thanks.

I have a select box that I need to sort.

<select name="people[peoplekind_id]">
<% @peoplekinds.each do |peoplekind| %>
<option value="<%= peoplekind.id %>"
<%= '' selected'' if peoplekind.id == @people.peoplekind_id
%>>
<%= peoplekind.name %>
</option>
<% end %>
</select></p>
<input type="submit" value="Update" />

In the controller for the List page I am able to use,  :order_by => 
''name'' , under the Def List.

 I have tried this in <% @peoplekinds.each do |peoplekind| %> above, 
but this does not work. How far off track am I?

Kindest regards.

When you retrieve @peoplekinds, either use sort_by or pass the :order  
=> ''name'' parameter when you call your model''s
find method.

You can also use options_from_collection_for_select(@peoplekinds,  
"id", "name", @people.peoplekind_id) to generate all the
<option>
tags for you; see http://api.rubyonrails.com/classes/ActionView/ 
Helpers/FormOptionsHelper.html#M000356.

I''ve found this kind of construct works (where arg might be your AR).

options_for_select(arg.sort{|k,v| k[1] <=> v[1]}, selected)

So, perhaps you''d be using:

options_for_select(people.sort{|k,v| k[1] <=> v[1]},
@people.peoplekind_id)

Hope this helps...

Thanks for the info, and thanks to those that emailed me with help.

The above two examples seem to be beyond me, but made for interesting 
reading, I have homework to do.

The soloution I came up with was to include the following under the 
controller for the page in question,

@peoplekind_pages, @peoplekinds = paginate(:peoplekinds, :order_by => 
''name'', :per_page => 30)

This seems to work but I''m gussing it is not a very ellegant approach, 
as I will have to repeat this under all the

def''s ....

end

that it needs to appear in.

Thanks again.
