Re: MVC-way to obtain common data formatting
I think the potential solutions have all been highlighted, but I'd
like to add my 2 cents.
If you insist on translating binary bool values into human readable
values, you should pair your afterFind() method with a beforeSave()
method. beforeSave() will then translate back from the 'human' values
into the correct format for the database. Note that this is more
commonly used when your database values aren't a good fit (your app /
data requirements have changed, but you are unable to modify the
database schema).
Personally, I usually just leave my values as machine readable until
they're ready to be presented to the view. For example: if a user can
select which states they have lived in, I keep my states as unsigned
tinyint(1) in the database (boolean true / false if they lived in that
state). This obviously is a weighty translation, so I made a method
in my AppController (now that I think about it, it should be in my
AppModel... but oh well) that will perform the translations for me.
Rather than having this: array( 'region_AL' => 1, 'region_AK' =>
0, ... ), I can have an array that has the state names in it (after
calling AppController::_translateState() ).
I'd suggest just leaving everything machine readable, then translating
it before display. Whether you translate in the controller, model, or
helper, is up to you. I'd recommend making it a helper -- seems the
most Cake-ish way to me.

Re: MVC-way to obtain common data formatting
You can try creating a couple of methods in your model.
One afterFind, and another beforeSave.
You can convert the data however you want in the afterFind, and then
convert it back in the beforeSave so that it doesn't mess up your
validation and save methods.
But you're going to run into other problems with this method as well.
The form helper might;' have some issues with the newly formatted
data, and not knowing exactly what to do with it.
Your best bet is to convert the data how you want right before
viewing. It's not the easiest to edit a lot of files, but it will
save you headache in the long run.
Also... to convert a 0/1 to a No/Yes, you can use the built in
Set::enum($select, $list = null) method, leaving the $list var empty
will auto populate it with a yes/no array.
echo Set::enum($data['boolean_field']) will output "yes" or "no"
depending on value. Wrap that in a ucfirst or ucwords to get "Yes"
"No", done.

Re: MVC-way to obtain common data formatting
Hmm I see ... well, I think this can only be accomplished with some
kind of helper method/class in the view, just like Jon Bennet says.
Imho a class like that will get bloated very quickly , because there
will be different options to choose from on how to display the data.
A small helper for translating model-specific values would be my
personal choice.

Re: MVC-way to obtain common data formatting
I don't really understand the problem you present.
Either you display a model field as a read-only piece of information
in the view, and then there is no problem with data being updated.
Or you display model data in a form that can be edited, and in case of
for example the boolean you provide a dropdown list or use a radio
button that displays a readable string to the user but holds the raw
data as the value.

Another way would be to create a helper.
How about this helper: http://pastie.org/595351
// use it like so
$data = array('Model'=>array('status'=>1));
echo $dataConverter->nice('Model.status', 'onoff', $data);
IMHO the thing to remember is that you only adjust the data for
presentation only, hence it's done in either the view or the
controller.

I would have thought the only time you need to display 1 or 0 as yes
or no is in the view. You're quite right that if you adjust the data
in app_model, it will break your DB.
I have a Config value set in my bootstrap, and output that. eg:
// bootstrap.php
Configure::write('yesno', array(0=>'No', 1=>'Yes');
// View
Configure::read('yesno.'.$row[$modelClass]['field']); // outputs 'Yes'
for 1, and 'No' for 0.
