Anyone know how to send a file/data to the user agent (download it)
using #send_file or #send_data, *and* render a new page in the same
action?
This just sends the file and doesn''t render the page:
def gimme
...
send_data(our_data, :filename => ''output.csv'',
:disposition =>
''attachment'')
end
And this will give a Double-Render error:
def gimme
...
send_data(our_data, :filename => ''output.csv'',
:disposition =>
''attachment'')
render :action => :gimme
end
As will a redirect. Hopefully I''m missing a really obvious solution
here.
Any ideas? Thanks.

That works fine. Not exactly elegant or very Rails-like, but it works! I''m still open to other ideas, but at least this gets me going again. Anyone know if there''s a (real) reason why you can''t send a file/data and render a page using the common Rails methods? (Besides the fact that someone early on forgot about this possibility when creating the code that checks for a double-render...) /kian -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

One response. You''re trying to respond with two things :) You could wrap this up in a helper/plugin to hide what''s going on, but this is still going to be the end result :) -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Since I''ve really got data that I want to send (rather than a file), and I don''t want to create a temporary file from it, I instead put it into the flash. The new URL in the META tag is a controller action that pulls the data out of flash.now and uses #send_data to create the response. Works well, except for the ugliness of putting that meta tag in the layout for this view only... -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Sending the correect header is definitely nicer. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

And you''ll find other uses for it too... like having a yield block for javascript that *has* to go at the bottom of the page just before the closing </body> because IE can''t deal with it in the middle, etc... -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

But if you need to cache that page then this wouldn''t work... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
