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
Bob

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. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

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)

But be aware that you cant double render, it will always raise an exception. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

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?
