obj.atr
Block below is valid for the block above:
def x(obj, atr)
return obj.send(:atr)
end
Have fun! Please, let me know how will you use this code, if you find it useful at all. In example, I can see that it can be used for something like this:
p User.find(:first, :condition => {:userid => 1}).name
This will drop an exception, if there is no such user with id 1. However, you can call it through the wrapper:
def wrp(obj, atr)
if obj.nil?
then
return "N/A"
else
return obj.send(:atr)
end
end
...
p wrp(User.find(:first, :condition => {:userid => 1}), name)
This might be awkward, but works well enough.
P.S. Here is the original question posted in Twitter and replies to it. (Thanks to Tweeplies.)
