Rails - Sep 2006 - collection_select is quoting my text_method text ?

I have a table that contains currencies I support which has the
columns:
 id,
 ch (the character to display when showing currency)
 name (the human name of the currency ...)

This table is currently loaded with these values:

currencies:

   Name     ch
  --------     --------------
  U.S.D     $
  Euro       &euro
  G.B.P.    &pound

I created a method in my ''currency'' model called
''menustr'' which I use
in collection_select to show the currency options:

  def menustr
    return ch + " " + name
  end

I then use this in my form template:

    <td><label for="customer_def_cur_pref">Default
Currency:
</label></td>
    <td><%= collection_select("customer", :def_cur_pref,
@zcurtype,
:ch, :menustr) %></td>

where @zcurtype is an array containing all the currencies in the
currencies table.

Instead of putting the pretty html version of &pound and &euro in my
pull down menu, collection_select''s form is quoting them and I still
see the "&pound" and "&euro" text.

Anyone have a way to work around this?

Thanks!

Append a semicolon to the values in your table that are HTML symbols.

Thanks for the response.  I have the semi-colon on the end of my values
for ''ch'' in my currencies table.   If I list my table using
the default
scaffolding, I get what I want:

Listing currencies (sorry for the formatting)
Name 	Ch 	Menustr 	Actions
USD 	$ 	$; USD 	Show 	Edit 	Destroy
Euro 	€ 	€; Euro 	Show 	Edit 	Destroy
GBP 	£ 	£; GBP 	Show 	Edit 	Destroy


However, when I populate a pull-down menu using collection_select, the
symbol reverts back to either &pound or &euro which doesn''t
look as
pretty :-(

My controller does this:

def new
    @customer = Customer.new
    @zcurtype= Currency.find(:all)
end

and the chunk in the form template does this for the pull-down:

  <label for="customer_def_cur_pref">Default Currency:
</label></td>
  <%= collection_select("customer", :def_cur_pref, @zcurtype, :ch,
:menustr) %>

...  Looking at the generated html, you can see the &amp ... prefixes
on the code plus the extra semi-colon I added to see if it would help
:-)

   <label for="customer_def_cur_pref">Default Currency:
</label>
   <select id="customer_def_cur_pref"
name="customer[def_cur_pref]">
     <option value="$" selected="selected">$;
USD</option>
     <option value="&amp;euro;">&amp;euro;;
Euro</option>
     <option value="&amp;pound;">&amp;pound;;
GBP</option>
   </select>

Yes, the Rails select options builder is calling html_escape on the
option texts and values.

You''ll either have to build your html options manually, or override
the html_escape method.

Aha... So collection_select escapes html.  That explains it.  I will
use your suggestion and build up the option lists manually.

Too bad we can''t pass an :escape => false or something to
collection_select.

Thank you!

Mark,

You are correct.  I didn''t know that it did that until now but now I
do.  It''s too bad we can''t pass an :escape => false or
something to
collection_select.

Thank you for you help,

Dan

Good idea.  While the value tag of the option must be escaped
(see http://dev.rubyonrails.org/ticket/2011), the option text
is html, and that need not be escaped.  I''ll submit a patch.
