Hi guys,
really really long time i did anything here :).. and no this time not an usual bhaana(excuse) will do but an genuine reason.. was busy building something good.. and it is a secret(just can't disclose it here like this).
Anyhow coming to point.. i was doing a general routine development task for my company and i got hit by a situation like this.. where i was making an ajax call to a controller/action and in response i was sending a stream i.e (send_data and send_file) but as the post was xmlhttp everything was working fine but download was not available (and yeh over here i coded it for download not the inline stuff). What to do now.... i searched it ya ya googled it and response was not a solution that i can rely on(it might not be google's fault must be mine, but why am i favoring it.. it must be google fault lol :)) )
So i solved it my own way by redirecting the update to other action and coding the stream in the newly redirected action :)
Here are some snippets of it....
<%=link_to_remote "Export the result",:url => {:controller => "some_controller", :action => "ask_to_export"},:with => "'record_ids=1-2-3-4-5-6'" -%>
def ask_to_export
render :update do |page|
page.redirect_to :action => "process_and_export", :record_ids => params[:record_ids]
end
end
def process_and_export
outfile = ""
CSV::Writer.generate(outfile) do |csv|
csv << ["praveen","kumar","sinha",1,2,3,nil,""]
end
send_data outfile, :type => 'text/csv; charset=iso-8859-1; header=present', :disposition => "attachment; filename=report_#{Time.now.to_f.to_s}.csv"
end
I hope this must be helpful to some one stucked over here and googling it
Thanks :)
