Hi,    I have created the url "http://localhost:3000/groups/home?group_id=1&parent_id=3"\.   I have one method in which I am able to access the url parameters by using params[:group_id] and params[:parent_id]. My question is that how the params hash is get created? and who creats this hash?

Thanks, Tushar

ActionController creates it for you (grungy details in request.rb)
