I have 2 radio buttons like this: <%= radio_button ''group'', ''public'', true %> <%= radio_button ''group'', ''public'', false %> They hold the correct values when viewing the @group object. However, when updating, it does not appear that the params[:group][:public] value is being typecast correctly. As params[:group][:public] = "true", "true" should be resolved to a "1" in the database. However, this is not occurring. Has anyone else seen this issue or have a suggested fix?

However, this is not occurring.What is typecasting? Seriously, radio buttons return string literals back in the params, so true comes back as "true". If you want it to map to 1 or 0, set the radio button to return "1" or "0". in ruby at least.... true.to_s => "true" (true == 1) => false _Kevin -- Posted via http://www.ruby-forum.com/.
But that''s the problem...if I set the value of the radio button to "1", it won''t show up as selected when rendering the view because Rails will only mark it selected if its value is "true." So if I set the value as 1, the attribute value is saved correctly to the DB...but then the button won''t be selected as the attribute it is tied to has a value of "true." As you said: true == 1. - Derek - Derek On 1/11/06, Kevin Olbrich <kevin.olbrich@duke.edu> wrote:> Derek Haynes wrote: > > when updating, it does not appear that the params[:group][:public] > > value is being typecast correctly. > > > > As params[:group][:public] = "true", "true" should be resolved to a > > "1" in the database.

<%= radio_button ''group'', ''public'',
"1" %>
<%= radio_button ''group'', ''public'',
"0" %>
This works...
the params hash will look like this {... "group" =>
{"public"=>"1"}}
when the first one is selected.
The first radio button will be selected if ...
group.public == "1"
Hope that helps...
