Good morning! I have a case where I need to build a csv file from my
model and allow a user to download/save that file. I''ve got this all
working with non-Ajax forms, but the generation of the csv file can take
quite a bit of time, so I want to provide a busy indicator for my user.
So I tried the following in my view:
<% form_remote_tag ( :url =>{:action => ''all_open''},
:update => "test" ,
:before =>
"Element.show(''busy_indicator'')",
:complete =>
"Element.hide(''busy_indicator'')") do %>
<%= submit_tag ''Save Report'', {:name =>
''save_report''} %>
<% end %>
which only updates the "test" div, as I expected (but this
isn''t what I
want since the data is already displayed in a pretty table on the page).
I googled and found suggestions to try send_file, but since I''m
building
my csv from a model and don''t want to save the file server-side, this
won''t work. I also found http://www.ruby-forum.com/topic/111107, but
I need the busy indicator so user''s don''t mash the save button
incessantly. Is there any way at all to pop up my busy_indicator and
still start the file download?
Any help/advice would be greatly appreciated (especially if it''s
quick...this is the last thing I need to fix before deploying the
app:)).
Thanks in advance!
-Chris
