Optionally pass a parameter?
In general, how do you optionally pass an optional qualifier to a Ruby
For example, for some model in Rails, like this:
How do I optionally add a condition? This generates a syntax error:
some_test ? :conditions => "id=100" : nil,
I guess it doesn't like that I only want to add the :conditions
occasionally. What is the Ruby best practice or idiom for this?

Try turning it inside out:
:conditions => (some_test ? "id=100" : nil)
:conditions => (some_test && "id=100")
Not too sure about what the second one will cause Rails to do if some_test
is false rather than nil, but worth a try.
