Hey All, very simple question for you folks ;) I have a @commutes object that for each record there is a bit value set (0/1) to denote if an accident occurred. What I want to do is have it display "Yes" or "No" when I view the listing of commutes. I can get it to display the bit value just fine with <%= commute.accident %> but how can I get it so that when a record with a 0 comes up that it displays "No" and if a 1 "Yes"?

<%= commute.accident ? "Yes" : "No" %> Michael
Perfect! That''s exactly what I needed. Ryan On 2/26/06, Michael Trier <mtrier@gmail.com> wrote:> > <%= commute.accident ?

Maybe you can try the Acts_as_bitfield plugin http://wiki.rubyonrails.org/rails/pages/Acts+As+Bitfield+Plugin Cheers! -- Mathias Stjernstrom On Feb 27, 2006, at 2:38 AM, Ryan Prins wrote:> Hey All, very simple question for you folks ;) > > I have a @commutes object that for each record there is a bit value > set (0/1) to denote if an accident occurred.

E.g.: <%= commute.accident.YesNo %> Is it possible to define the method in such a way that it is available for every boolean attribute in my model?

Probably, and in that case you would open up the ActiveRecord::ConnectionAdapters::Column class and add in the method, for instance boolean_to_string. That may or may not be the right spot for it. Generally what I see is that you would define a helper, and use that. For instance, in your helpers/application_helper.rb file put in something like def YesNo(value) value ? "Yes" : "No" end Then in your view you do <%= YesNo(commute.accident) %> Now granted, I''m just learning this stuff, so there''s probably another way that is a much better approach. Michael
Just to clarify: <%= commute.accident ? "Yes" : "No" %> Didn''t work for me, but the following did. <%= commute.accident == 1 ? "Yes" : "No" %> Thanks!

I would think that <%= commute.accident? ? "Yes" : "No" %> should have also worked Craig On Mon, 2006-02-27 at 20:52 -0800, Ryan Prins wrote:> Just to clarify: > > <%= commute.accident ?

You might want to handle true and false different from zero and nonzero.
Rails translates bits to boolean TrueClass and FalseClass, so this code
works for me:
# Translate boolean true/false to string ''Yes'' /
''No'' for
human-friendly reading
# of checkbox fields.
def handle_translations(field)
case field
when TrueClass, FalseClass
(field) ? ''Yes'' : ''No''
else
field
end
end
