Re: [Rails] Re: Rails and Service Oriented Architecture (SOA): any downsides?
Lille, sinatra is WAAAY better than rails for building a web service API - I've built two API's in sinatra in the past week, one of them took only 1.5h (this w/ oauth, get/put/post/delete, etc.). Compare this to when I tried to build an API in The Rails Way , which at the time was ActiveResource (which has since gone fallow), which took weeks. If you're using something like amazon's S3 or SQS or SimpleDB, then congrats, you're doing SOA. My understanding is that the culture inside Amazon was always very heavily SOA-oriented, and top management frowned on efforts that involved reinventing commodity functions like storage or queueing - and this led to their cloud business. The S is SOA is Service - if you want to provide a service, then SOA may be a good idea. If you want a nice clean separation between API and everything above, and if you think your web service API might some day be used by other business units, partners, mashups, etc., then sure, you can think of it as a service and you're doing SOA. AFAIK the only connection between SOA and performance is that you can focus on optimizing your service, and if you provide a really good service you could perhaps have economies of scale - but on the other hand you can focus on optimizing any section of code. m On Thu, Aug 4, 2011 at 4:15 PM, Lille lille.pengu...@gmail.com wrote: Hey folks, I allow that I likely mangled the use of the term 'performance', but I think the question stands, because anyone consciously refactoring their Rails app to accommodate an SOA approach would surely know it: models now implemented as services would respond to HTTP requests or messaging services like RabbitMQ.

A part of my Rails app could possibly succeed as its own app, while its existence also benefits the rest of the app I have underway. Shouldn't I want to develop this independent piece as an autonomous service while also allowing for its use by the rest of the app? It is said... + organizational efficiency - services are isolated, so development teams focus on their assigned service(s) alone + robustness - services have their own data stores and modifications to them is independent from other services + scalability - rather than optimize the common Rails data store to meet all cases entailed by use of the app, each service and its associated use case entails its own particular database optimization Lille On Aug 2, 4:09 am, Chris Kottom ch...@chriskottom.com wrote: SOA and performance are two of the most abused terms in IT, so definitions matter a lot.

That being the case, I have a hard time understanding the original question because all of these concepts seem to be more or less orthogonal to one another. Architecture and implementation technology are certainly going to have an effect on performance, but they don't determine performance or scalability (related term, though not the same, also badly abused) as much as how they're applied which is largely determined by application complexity and the skill of the development team.

Re: [Rails] Re: Call Rest webservice in Ruby on Rails
Allow me to second the recommendation to read up on ActiveResource - this is
exactly what it's designed for, and in fact if you're also developing the
ReST API, you can use ActiveResource to impose convention (over
configuration) in your API - plus you'll have a nice test rig when you're
done.
Only issue is whether enough people in the Ruby community see AR this way
and whether it will continue to be maintained.

Re: [Rails] Re: Upcoming app Research and Prep
Well, if you like ActiveRecord and SimpleDB (aws), I recommend http://github.com/appoxy/simple_record However, and I don't mean this to inflame anyone, but ActiveRecord may fundamentally oppose NoSQL - while ActiveRecord makes joins easy (for the programmer, not so much for the db), those joins don't scale well. [To other people's points, a single MySQL can take you a very long way with minimal joins and good row-level caching.] The NoSQL way is to get (minimal) results from a single table at a time, then if necessary, do other queries to get connected data. In other words, instead of sending joined queries to the db layer, you unwrap (efficiently) them in your code. marc -- getCloudCache.com On Wed, Mar 24, 2010 at 5:13 PM, brianp brian.o.pea...@gmail.com wrote: On Mar 24, 4:59 pm, Marc Byrd dr.marc.b...@gmail.com wrote: Life may be much simpler for you when you scale if you use a nosql option, What nonsql option would you recommend? -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Of course that's best used if you're on EC2 (or EngineYard on EC2).

It completely depends on your application. I've run sites that had 4
servers with 1gb each, I've run sites that have 64mb... you need to
figure out how much data you need to store. Start with 64 and let it

get some data on how it's doing. Scroll down till you see the stat

compression? Not sure what you mean. Memcached is very fast. Most

You shouldn't need a plugin to get going... add this to your
environment.rb (or one of the specific ones in environments)
config.cache_store = :mem_cache_store, localhost, {:namespace =
'foobar'}
Then in your views you can do things like:

While I don't recommend this as a long-term solution, it should help know whether this is the issue (make a backup first w/ current permissions): chown -R www-data:www-data /usr/lib/...gems I believe I also did chmod 777 /usr/bin/gem_file I also modified the /etc/init.d/apache2 script, adding to the ENV line things like: ENV=env -i LANG=C PATH=/usr/local/bin:/usr/bin:/bin:/usr/lib/ruby/gems/1.8/gems/simple_record-1.0.2/bin:/usr/lib/ruby/gems/1.8/gems/cloud_cache-1.0.1/bin /etc/init.d/apache2 restart - (The more proper way to do this [should be built into ./bin/passenger-install-apache2-module ?] is to give these files group permissions, include www-data in the group). Other observations: 1) I had to include the full path for passenger-install-apache2-module, didn't work as # passenger-install-apache2-module , not found) 2) script/console, script/runner, script/server - all worked fine, but passenger/apache2 didn't work until I got permissions right. Good luck, m On Mon, May 18, 2009 at 11:08 AM, karl kpb...@gmail.com wrote: Ok, tried these things. The gems are the same. Changing permissions doesn't do anything.

[Rails] Re: Gem path problems w/ Passenger+Apache2
Platform - Ubuntu, 32-bit on EC2, jaunty jackalope On line that says require 'cloud_cache' it says file not found. Note that in order to get require 'simple_record' to load properly I had to chown www-data:www-data on its files. I did the same on cloud_cache files but no joy. Again, all work perfectly well under webbrick. thanks, m On Fri, May 8, 2009 at 6:17 PM, Conrad Taylor conra...@gmail.com wrote: On Fri, May 8, 2009 at 6:13 PM, Marc Byrd dr.marc.b...@gmail.com wrote: Anyone else having a dickens of a time getting Passenger+Apache2 to recognize the gem path?

[Rails] ActiveSupport::Cache vs. others?
Hi, We are building and using a new caching gem. We would like to figure out how to make this most friendly and easy for both existing projects and new projects to use. I'm guessing the best way to get used in new projects would be via subclassing the ActiveSupport::Cache::Store class? Is this expected to be the primary way to use a cache going forward? What about gems that may be widely used in existing projects like cached_fu, memcached, etc. ? Are these expected to be rolled in through ActiveSupport::Cache over time? If you had to chose one cache interface to speak (e.g. drop-in replacement, small constructor diff only, or config diff only), which one would you suggest? And if only two, which two?

[Rails] Re: Track number of clicks on a link
Note that writing to the db every time something on your site is viewed can
really limit your capacity and scale and hasten the day when you'll need to
think about multi-master configuration. So unless you're using something
like amazon SimpleDB, which scales for you, it might be better to figure out
a better way to track view counting (e.g. central log server, cron job to
aggregate and update db?).

Hello,
So I am trying to simply track the number of hits a link has received
and display that number on the site so other users can see which links
are more popular. So once the link is clicked on it adds a +1 value to
the hits column in the database and then redirects the person to the
url that the link is supposed to go to. So far this is what I have.
I have a tutorials table in my database and a column for hits and a
column for url.
** tutorials_controller.rb **
def update_hits_count
@tutorial.update_attribute :hits, params[:count].size + 1
if @tutorial.save
redirect_to url_for(@tutorial.url)
end
end
modify the method so it suits any controller,
like in self.update_attribute
add the method to application_controller
whenever you want to add a hit you call it,
like in
def index
update_hits_count
end
** view/tutorials/show.html.erb **
% for tutorial in @tutorials %
%=link_to tutorial.title, {:action = 'update_hits_count', :count
= tutorial.hits} %
% end %
That is what I have so far and when you click on the link the hits
column in the tutorials table just gets set to null and it does not
redirect them to the proper url. Any help would be greatly
appreciated. Thanks in advance.
