I’m trying to use a select list for a boolean field in my model. I
want there to be three values in the list: nil, true, and false. Here
are the snippets of code I have so far:
<%= f.select :yes_to_terms, [[‘Yes’, true], [‘No’,
false]], :include_blank => '–select one-- %>
The problem I’m running into is that if someone selects ‘–select
one–’ in the drop-down and submits the form, my app interprets the ‘–
select one–’ as false (it’s values is an empty string in the html).
I tried changing the list of options to this:
[[’–select one–’, nil], [‘Yes’, true], [‘No’, false]]
But that didn’t work either. Does anyone have any ideas? Also, I can’t
use a checkbox for this app, since I need to know whether the value is
true, false, or unknown.
