if i want a link to book\_url(@book), but i want to pass an additional  
param, how to i do that?

i want it to result in something like [http://localhost/books/1?foo=bar](http://localhost/books/1?foo=bar)

this works, but seems hackish:

url\_for(:controller =\> book\_path(@book), :foo =\> “bar”, :only\_path =\>  
false)

book\_url(:id =\> @book, :foo =\> ‘bar’)

You have to use the hash format even for the :id when you want to add  
other parameters.
