Rails 3, saving data without a form

Question

How do I save information from my site http://yocoro.com/public into my database ? just by going to the page

PS: I'm using 2 gems geocoder and user-agent to optain this information.

//controller
class PublicController < ApplicationController  
  def index  
      @time = Time.now  
      @user_agent = request.env['HTTP_USER_AGENT']  
  end  
end

//view
<%= request.ip %>
<%= request.location.city %>  
<%= request.location.country_code %>  
<%= @user_agent %>

Based on input from @meager I was able to trim this way down.

Create a model and the appropriate table to go with it

rails generate model location ip:text city:text country:text user_agent:text

Then in your index action just put the info together and store it:

def index
  @ip = ip_param
  # Here is where you use the IP address and the geocoder gem to gather the 
  # info from the ip address. Then create the location object and save it.
  @location = Location.new
  @location.ip = @ip
  @location.city = city
  @location.country = country
  @location.user_agent = request.env['HTTP_USER_AGENT']
  @location.save
end

here is how I finally did it.. I try this before it didn't work but I finally understand why, my old code had "@location = location.new" the letter -l- was lower case and rails was giving me an error after I change to "@location = Location.new" bingo bango it worked!!!.

thank you so much to everyone.!!!

  @location = Location.new
  @location.ip = request.ip
  @location.city = request.location.city
  @location.country = request.location.country_code
  @location.user_agent = request.env['HTTP_USER_AGENT']

  if @location.save
    flash[:notice] = 'Location save'
  else
    flash[:notice] = 'Location did not save' 
  end
