saving variable to file and downloading it

I've got a problem with my previous question. Nobody can't help me so I'll try to write better this time what I want:
- I've got a
generators#show
view, and in this view I want to do everything without refreshing page after clicking a button etc. - I've got a variable (it is nowhere stored - just dynamically put on
the site):
@bigtable
, which is actually an array of strings - I have a button placed in this view:
<%= form_tag do %><%= submit_tag 'Save it' %><% end %>
- If someone will click on that button I want to pop up an window and
he could set where he want to save a txt file (and set filename),
filled with all
@bigtable
array records.
For couple days I think I've tried everything but I don't really understand how to solve it. Could someone, please write here what methods in model and controller I should write? And all required routes? I'll really appreciate any help. My previous thread (but please do not send me there or give same answers like there): saving file after passing parameter
解決
finally I've found a solution:
def savefile
@generator = Generator.new(params[:generator])
@bigtable = Rails.cache.read("pass")
doc = "wyniki.csv"
File.open(doc, "w"){ |f| f << @bigtable}
send_file(doc, :type => 'text; charset=utf-8')
end
