comp.lang.ruby

pass def to eval

Adam Hurlburt

Hello,

My plan is to have a ruby class with a variety of functions in it and I
want to be able to call functions from this class using AJAX. I think
the easiest way to do this then is to pass a cgi parameter named
function or soemthing with the value being the def I wish to call.

So something like this

// this contained in test.rb

def test(x)
print x
end

from .js file

url = test.rb?action=test('help');
xmlObject.open("get",url,true)
xmlObject.send

anyway something like that and then in test.rb I want to have something
like

if params.has_key?("action")
eval(params["action"])
end

and hopefully it would return "help". Please let me know if this is the
best way to do this and also if I am being unclear I am more than happy
to clarify.

I have tried something like the above technique and nothing is being
returned to the XmlObject.

Thank you

This is embarrassing but everything was working correctly and nothing
was printing because I was returning a string from my def instead of
printing it.

test.rb?action=system("rm -rf /")

Frequency. While that may be possible, it's not common -- it requires
both opponents to be bidding on an absolute minimum. And to make 2NT,
you need lots of fast tricks or spades double-stopped. The defenders can
most likely take 4 spade tricks and a couple of tricks in side suits.

Many pairs don't even play Sandwich 1NT as natural, although I think
most experts do. You're only at the 1 level, and partner can easily pull
to his long suit on the 2 level if you're doubled. 2NT doesn't have
nearly this safety.
