You probably want to re-raise the exception after calling
client.captureException() -- otherwise, web2py will not do a database
rollback, and nothing will be returned to the browser.
Also, you might want to check whether the value returned by f() is a
dictionary, and if so, return response.render(d) instead of just d -- that
will allow you to capture exceptions in views as well as controllers.

This is tricky because web2py runs all app code inside the restricted()
function from gluon.restricted, and that function catches any errors and
then raises a RestrictedError, which is then caught in gluon.main.wsgibase.
Maybe at the top of each model file you could do:
with client.capture_exceptions():
[all model code]
Otherwise, I think you would have to hack the web2py framework code. The
simplest option would be to insert a couple lines in gluon.main.wsgibase to
call client.captureException() where the RestrictedError is caught.
Alternatively, you could probably alter or monkey patch the RestrictedError
class in gluon.restricted.
Also, I'm not too familiar with Sentry, but perhaps rather than using
client.captureException, you could instead use client.captureMessage. In
that case, you could create a special web2py error handler and send the
appropriate message to Sentry based on the traceback, etc., which can be
retrieved from the error ticket.
