Hi, i’ve a page where when a params[:something] is passed all/some the urls in that page must have the params[:something] too, but when there isn’t it shouldn’t appear. I’ve tried with: report\_url(params[:id], :something =\> params[:something]) this works when there is the params[:something], but it doesn’t when there isn’t, as the result is: [http://localhost:300/report/1?something=](http://localhost:300/report/1?something=) So i’ve tried with tmp = params[:something] ? {:something =\> params[:something]} : {} report\_url(params[:id], tmp) This is better, because works when there is the parameter, and almost does when there isn’t, as the result is: [http://localhost:300/report/1](http://localhost:300/report/1)? Is there any way to have the two results [http://localhost:300/report/1?something=123](http://localhost:300/report/1?something=123) and [http://localhost:300/report/1](http://localhost:300/report/1) when there is and there isn’t the parameter? Without having the question mark at the end in the second case ---
