How to populate a select list.

I''m creating a simple ''Yes/No'' select droplist.  I
thought the select
tag accepted a hash. But, it doesn''t show any items when I view it.
This is the code in Markaby 0.5.

select_tag( ''work_order'',
''warranty_work_ny'',{"Yes" => "Y",
"No" => "N"})

There must be an obvious error in there somewhere,  I''m just not seeing
it.

try

select_tag(name, option_tags = nil, options = {})
but
select(object, method, choices, options = {}, html_options = {})
try
select_tag(  ''warranty_work_ny'',{"Yes" =>
"Y", "No" =>  "N"})

Re: How to populate a select list.

You want the select helper, not select_tag, since you are tying it to 
your work_order.warranty_work_ny method. This helper accepts an array of 
arrays for the choices, not a hash.

Here''s how you do it...

select(''work_order'', ''warranty_work_ny'',
[["Yes","Y"],["No","N"]])

For a boolean state object I suggest one of two approaches....
1. A checkbox or
2. two radio buttons.

In your case, it sounds like you really need to put in a checkbox

I use the radio button approach when the states match to a small set of
mutually exclusive states that don''t neatly map to a true/false.
Things like ''gender'' are a good example.

select_tag takes: name for params, options for popup, html options.   
So you have an extra argument slipped in there, and you should really  
use options_for_select to build the options string.  try:

select_tag(:warranty_work_ny, options_for_select({"Yes" =>
"Y", "No"
=> "N"}))

 From the survey design PoV, any binary (Yes/No) question has four  
possible and appropriate responses:

Yes;
No;
Don''t know;
not applicable.

Plus also:

Not Answered.

Most binary survey questions fall into the same camp.  From the UI  
perspective, popups/dropdowns are biased towards the first option,  
the one that shows by default.
