FreeBSD, Perfect Fit.

Ha pasado mas de una decada en que probe FreeBSD y otros unix. He probado todo unix que se me ha cruzado. FreeBSD logro superar todas mis expectativas, desde el primero al ultimo dia. Muchas Gracias a toda la comunidad de FreeBSD. Los veo como el mejor ejemplo de apertura de conocimiento. http://fusionisfreedom.blogspot.com.ar/2012/05/freebsd-un-mundo-aparte.html

ruby on rails, googlebot(at)googlebot.com, No HTTP_REFERER, canonical and consistent websites

---

When you have an exception from the system, something like:

---

Subject: [ERROR] ships#flag_choice (ActionController::RedirectBackError) "No HTTP_REFERER was set in the request to this action, so redirect_to :back could not be called successfully. If this is a test, make sure to specify request.env[\"HTTP_REFERER\"]."


A ActionController::RedirectBackError occurred in ships#flag_choice:

No HTTP_REFERER was set in the request to this action, so redirect_to :back could not be called successfully. If this is a test, make sure to specify request.env["HTTP_REFERER"].

---

Is your chance to make a better website, a browseable website for robots.

---

Here you have:

app/controllers/application.rb

before_filter :load_url_back

def flag_choice
  set_locale(params[:id])
  session["lang"] = "#{params[:id]}" 
  #redirect_to :back
  redirect_to params[:url_back]
end

def load_url_back
  @url_back = "http://" + request.env["HTTP_HOST"]
              + request.env["REQUEST_URI"]
end

apps/views/layouts/application.html.erb

<%= link_to(image_tag('ingles.png'),
:action => 'flag_choice', :id => 'en_EN',
:url_back => @url_back ) %>
<%= link_to(image_tag('esp.png'),
:action => 'flag_choice', :id => 'es_AR',
:url_back => @url_back ) %>

---

Now we have consistent links that can be saved in any place, and consulted without history of browser navigation. This makes your links independent from where you came from.
And in the controller you are working in a request that just need canonical information from the HTTP Request.

ruby on rails can't convert Symbol into String date_select, i18n

config/locales/es-ar.yml

"es-ar":
  hello: "Hola mundo"

  date:
    formats: 
      default: ""
      long: ""
      short: ""
    order: [ :day, :month, :year ]
...

ruby on rails, ActiveResource::Base, paginate, WillPaginate, RESTful xml resource and paginate

This sample assume that you have a service in the server that respond .xml

class NoteIntranet < ActiveResource::Base
  self.site = INTRANET_CREDENTIALS[:site]
  self.element_name = 'note'
  cattr_reader :per_page
  @@per_page = 20
  def self.paginate(*args) 
    options = args.pop 
    @@per_page = options.delete(:per_page) || @@per_page
    WillPaginate::Collection.create((options.delete(:page) || 1), @@per_page) do |pager|
      all_elements = self.find(:all, options)
      result = all_elements[pager.offset, pager.per_page].to_a
      # inject the result array into the paginated collection:
      pager.replace(result)
      unless pager.total_entries
        # the pager didn't manage to guess the total count, do it manually
        pager.total_entries = all_elements.size
      end
    end
  end

end

In the controller you may have conditions that are defined in the service, an example is a filter:

      @notes = NoteIntranet.paginate(:page => params[:page], :params => { :title => params[:title] })

In the server service, in the controller you have:

      @notes = Note.paginate(:page => params[:page], :conditions => ["title like '%?%'",params[:title]] )

This idea came from Gasper - Luis Guardiola
