I am new to Ruby on Rails. I am trying to create a form and submit it and show the submitted values in a page. But i am getting error most often, can any one help me to work around this with any simple example or simple link?

Simplest way to create a form without REST is

<%= form_tag '/some_path' do %>
   <%= text_field_tag :name %>
   <%= submit_tag %>
<% end %>

and then you can get to the value of the text field via params[:name] . This will be available in a controller, for example.

# routes.rb

match "/something" => "home#something"

# home_controller.rb

class HomeController < ApplicationController
  def something
    # this will output raw text/plain with the content submitted via the form
    render :text => params[:name]
  end
end

It would be helpful if you could provide exactly what error are you getting and an example of your code.
