Differences in execution between console and app

You can't create a Range over 2 Dates and iterate over those - I'm
assuming that's what you want to do.

but what you can do is iterate over the lookahead

(0..look_ahead).each do |diff|
  yield (date+diff.....)
end

ok i seems you sometimes CAN create ranges of dates - but that it
doesn't work in a running app points towards some strange view-helpers
being added to the date-class or something like that.
my method should still work, while yours implies some kind of hidden
to_i/to_date back-and-forth which could lead to that error. don't try
to force it if there is another way.

I think we've gotten a little off-track. Allow me to steer us back in
the right direction...

This is the line throwing the error in my app:

appointments.find_all_by_date(date)

What's the stack trace of the error?

ah .. yes sorry I seem to be responding while new and clarifying
messages are added to this thread.. that way I got off-track.

have you tried converting the date to a string before the
find_all_by_date() ?
or formulating it as a :conditions array ?

these are not solutions but you could analyse the problem from
different angles like that.

Oh, yeah, weird. I would just change it to
appointments.find_all_by_date Date.today.to_s(:db)

and cross my fingers.

What database are you using? Version, and adapter version? It looks
like AR isn't treating something as a date there. Like it's
sanitizing the SQL as a string...which most likely means (to me) that
for some reason it doesn't know that the db column is a date. Did you
perhaps mess up on the migration and create the date field as a string
instead of a date?

What does the (:db) to?

ActiveSupport overrides Date#to_s, passing :db makes it format the
string in the way the database wants it.
