I was trying to use postbacks, but its not working.

def edit  
@xxxx= xxxx.find\_by\_id(params[:id]) || xxxx.new  
if request.post?  
@xxxx.attributes = params[:xxxx]  
redirect\_to :list and return if @xxxx.save  
end  
end

I get the following error: SystemStackError in xxxxxController#edit  
stack level too deep. The code of list is same as the code generated by  
the  
scaffold generator. The stack trace is below:

e:/program  
files/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action\_controller/base.rb:854:in  
`redirect_to' e:/program files/ruby/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_controller/base.rb:854:in `redirect\_to’  
#{RAILS\_ROOT}/app/controllers/xxxxx\_controller.rb:23:in `edit’

The record is created but the url is still  
[http://localhost:3000/xxxxx/edit/x](http://localhost:3000/xxxxx/edit/x)

I ran into the same problem recently and it was basically fuming when I  
realized it all boiled down to the incorrect parameters being passed to  
redirect\_to().

For your code sample below,

redirect\_to :list

should be  
redirect\_to action =\> :list
