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, ActiveResource::Base, paginate, WillPaginate, RESTful xml resource and paginate
This sample assume that you have a service in the server that respond .xml
In the controller you may have conditions that are defined in the service, an example is a filter:
In the server service, in the controller you have:
This idea came from Gasper - Luis Guardiola
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

Flash Messages, System Messages, Ruby on Rails, by style, debug and test
controller:
views/layouts:
css out of dev, in test, this can help you in both environments:
flash[:notice] = "Correct things."
flash[:error] = "Alert things."
flash[:debug] = "Simple debug."
views/layouts:
<%- flash.each do |name, msg| -%>
<%= content_tag :div, msg, :id => "flash_#{name}" %>
<%- end -%>
css out of dev, in test, this can help you in both environments:
#debug{
display:none;
}
