Hi,

I have just created a couple of ActiveResource classes that are being  
used to communicate with a rest api.

In every request I am having to place an api key as an additional param  
e.g.  
@book = Book.find(params[:id], :params =\> {:key =\>  
‘7348d92f82836eb9d5f69c0’})

Is anyone aware of a dry’er solution that will allow me define the  
additional param in the class below self.site or something similar?

Thanks,  
Scott
