You’re going to have to be more specific.

If you have:

def foo(*bar)
bar.class # => Array
end

So the parameters becomes an array of values, including an empty array
if nothing is passed in.

Then you can do stuff like:

foo
foo “one”, “two”
foo :a => “b”
etc.

Is that what you were looking for?

Another pseudo-random guess…

I’ve had several places where I’ve done something like this in a
controller:

FIND_OPTIONS = {:limit=>10, :offset=>0, :order=>:name}
def index
find_options = FIND_OPTIONS.dup
find_options.reverse_merge :name=>params[:name] if
params[:name].blank?
… other options…
SomeModel.find(:all, find_options)
end

That allows you to search only for arguments that are supplied by the
user (ignoring blanks as don’t cares).

If you want to only add/update data as returned from a form
submission… Rails already does that for you.
