Hey guys,

I want to use the current parameters for the page in a link_to

So I have the current url:

And I just want to overwrite or add parameters to that

I know I can use request.parameters.update(hash)

I remember saying another way to do it, it was a ruby helper variable or
something like that. Any of you guys know what im talking about?

I wonder if you are refering to #url_for(:overwrite_params => {:book=>5, :id=>8}).
I have a usage example documented on my blog below.
