i have an array @item = [ [name1, value1] [name2, value2] [name3, value4] ] which comes from the controller i want to put this into a drop down menu where the item chosen goes to :enter_by i also need to go back to the same form where the same array @item is displayed but this time the item selected ( :enter_by ) is now selected. i don''t want to use ajax i have read and re-read, and then made a trip to the bookstore about select, select_tag, options_for_select i going on 3 hours sleep in 48 hours and need this badly. this can not be soooooo complicated. i can get the items to display, i can return the item selected but i can not get the selected item to show if i go back to the form. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

hi rushnosh, i''m back (with a bit more time now) i posted what you wanted (as far as i understood you) in your last question. select which sets the selected items for a multiple select box. could you have a look at it and maybe tell me, what you don''t understand or what does not fit with your request? the only difference is, that in my example the array is hardcoded, but you can replace it with any array you want. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

ok, just typed that in:
in your controller:
@items = [[''A'',1], [''B'', 2],
[''C'', 3], [''D'', 4], [''E'',
5]]
this should''ve been returned (i simulate it):
params[:enter_by] = 2
in your view:
<%= select_tag("enter_by", options_for_select(@items,
params[:enter_by])) %>
where options_for_select gets two items:
the array with the options
the selected item
it should make no difference, if you render this the simple way or
replace it with ajax

i did look at your code and tested. it was not for a drop down. i finally, finally got it to work - but i can not believe this how ruby does it. it is extremely ugly. i know it can be done in a cleaner fashion with ajax/rjs but i didn''t want to add another level of difficulty to it. the help came from this post <http://www.falsepositives.com/index.php/2005/12/10/building-a-better- drop-down-selection-list-for-ruby-on-rails/> now i have to repeat this code about 100 times and i am dreading it. almost 2 days to figure this out. PLEASE, PLEASE let me know if there is a better way to do, there has to be, unless folks just don''t use drop down menus/selections anymore. until now i was so gunho about ruby.
