I'm trying to print a report as a pdf, which uses the render method. This works fine. The problem comes at the end when I try to redirect to the index page, which causes the double render. I'm sure there's a way around this, but I'm coming up blank. If I remember right, there was a method that acted almost like redirect_to, but wouldn't cause the error. Please help...
Thanks

How come you want to present the report and then close it and go somewhere else? people wont see it. i dont get it , it seems you used render where you should have used send_file but i need to see your code to be sure.
When I render the report, it's to a file that can be viewed, printed, or backed up as needed. It is to a pdf, so I'm using:
respond_to do |format| format.pdf { send_data render_to_pdf( :action => 'idreport', :layout => 'pdf_report'), :filename => "ID List for " + @today.strftime('%m-%d-%y') + ".pdf" } end Then the error is caused by a redirect_to(households_url)

I don't think you do - there can only be a single response to an http request, so you can't both provide a file and show a response (unless perhaps you were to do something like have your "success" page include an iframe with the actual download)

That i understand , you can render the file inline or send it to the user, what i dont understand is the need to redirect after that. Please explain. But be aware that you cant double render, it will always raise an exception.
The reason for the redirect_to is to end the process after the file is created at the index page so the user doesn't have to find his way back. Is there a way to go to the start or index page maybe?
