Passing information to the controller from view

Hi everyone,

I have a template called createFile.html.erb which has some ruby code in
it.  The ruby code pulls information from the database because i''m
looping through some records.  Is it possible to send all of the
information in the createFile.html.erb output to the createFile method
in the controller? I''m wanting to save the content of it all to a text
file...

Or is there an easier way to produce the same outcome?

Thanks,
McKenzie.

render_to_string puts the whole html document in the data including the 
template, however I only need part of the file. This code might explain 
it a little better.

#demo_controller.rb
   1. def createFile
   2.     render_to_string :layout => false
   3.     @demo = Demo.find(params[:id])
   4.
   5.     data = render_to_string
   6.
   7.     f = File.open("#{RAILS_ROOT}/public/demo/demotest.txt",
"wb")
   8.     f.write(data)
   9.     f.close
  10.
  11.   end

#demo/createFile.html.erb
   1. ModelTemp {
   2.         Name "Mod"
   3.   Halt 0.0
   4.   DType "Define"
   5.   FData {
   6.     Events {
   7.     <% for event in display_demo_events(@demo) %>
   8.       Event {
   9.                     Name "<%= event.name -%>"
  10.                     Desc "<%= event.description -%>"
  11.                     Constant {FRate="<%= event.f_rate
-%>"}
  12.                   }
  13.       <% end %>
  14.     }
  15.     Outputs {
  16.       <% for deviation in display_demo_events(@demo) %>
  17.       Deviation {
  18.                     Name "<%= deviation.output_class -%>"
  19.                     "<%= deviation.description -%>"
  20.                   }
  21.       <% end %>
  22.     }
  23.   }
  24. }

Re: Passing information to the controller from view

In your controller, you just need

   data = render_to_string({:action => ''create.html.erb'',
:layout=>false})

I''m doing a PDF (using HTMLDOC) that way. Works awesome.
