Sorry, I hit "Send" before I finished typing and proofing. Below is the
corrected and finished model layout. You don't want to use Attribute as the
name of a model or table.
class User < ActiverRecord::Base
has_many :photos, :dependent => :destroy
end
class Photo < ActiveRecord::Base
belongs_to :user
has_many :photo_attributes
end
class PhotoAttribute < ActiveRecord::Base
belongs_to :photo
belongs_to :photo_descriptor
end
class PhotoDescriptor < ActiveRecord::Base
has_many :photo_attributes
end
Your PhotoDescriptor model would be the list of descriptions/attributes
found in the photo (sea,green,sand,etc.).

You are going to want to do a has_many in the Photo model to PhotoAttribute
model. This will allow you to have the PhotoAttribute model be a list of all
the attributes that a photo can have. From what you explained this sound
like what you wanted to do with that table anyway. Your final models would
look like this:
class User < ActiverRecord::Base
has_many :photos, :dependent => :destroy
end
class Photo < ActiveRecord::Base

[Rails] Problems with SSL dependent gems OAuth2 & ActiveMerchant
Hello all, My application uses the OAuth2 gem (0.1.1) to connect to Facebook, and the ActiveMerchant gem (1.12.0) to connect to PayPal. Under what is the current Rails/Ruby distribution, both of these gems throw the following OpenSSL::SSL::SSLError when used: * SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed I did some digging, and found two patches. The first involves plugging this into my initializers folder as "faraday.rb" (http://bit.ly/hZqNwQ). The OAuth2 (Facebook) side of things does work with this patch. However, the ActiveMerchant (PayPal) code still throws the same SSL_connect error. The second patch I've tried (unsuccessfully) is the 'always_verify_ssl_certificates' gem (http://bit.ly/dXmuUh). I did the following things: (1) gem 'always_verify_ssl_certificates' in the Gemfile (2) require 'always_verify_ssl_certificates' in the ApplicationController file. However, both OAuth2 (Facebook) and ActiveMerchant (PayPal) throw the following TypeError: * wrong argument (NilClass)! (Expected kind of OpenSSL::SSL::SSLContext) Here are the links to my OAuth2 Facebook code (http://bit.ly/hRO0Yf) and my ActiveMerchant PayPal code (http://bit.ly/hQzdp6) as they stand now. This is after following the 2010 OAuth2 guide by Michael Bleigh and the 2008 Cody Fauser ActiveMerchant tutorial. Any help is greatly appreciated!

[Rails] Best practice question
Hi fellow rails users. :-) I'm starting to create a rails based application. It must be plugin based with authorization. I know of some authorization plugins which I will look at. My question is only about the best practice of making a plugin based application. Users must be able to create an instance of the application online and will be able to select which plugins they want to have included in their instance of the application. I'm a little confused. Is it best to use the plugin architecture that is built in rails do achieve this? How would I go around enabling/disabling plugin loading dynamically? All help is greatly appreciated!

You could just wrap the code in your method in a transaction block. As the docs say: +transaction+ calls can be nested. By default, this makes all database statements in the nested transaction block become part of the parent transaction. I.e., a nested transaction block does *not* result in a nested transaction. If you want the latter, you have to use transaction(:requires_new => true).

Can you give some examples of what your attributes are? You probably want to
avoid calling the association attributes - that will collide with an internal
activerecord method.
Fred
App has to work in this way, user add photo and then add attributes to
photo on example (Baltic Sea.jpg; sea, water, sand ).
Then usning Formal concept analysis (not relevant) special paris are
created {(photo,...,photo n),(attribute,...,attribute n)}
and it should be remember in some way (i suppose best will be another
table), because it will be modefied when photo table or
attribute table will change.
I can't find out the best way how associations between models should
look like and how many models i need.

Instead of :presence => true you should be able to say :presence => {...}

Re: [Rails] Service Management
I'm not necessarily an ITIL expert, but I've worked in environments and on projects where it was essential (technical infrastructure architecture, help desk application implementation) so I can probably get you pointed in the right direction. But because this has been a subject of real interest over the past few years as Ruby and Rails have matured for serious application development, there's a lot of information available out there, so don't stop your investigation here. There are a lot of different tools that are used for managing Rails applications. The best known paid options are probably New Relic RPM ( http://newrelic.com/) and Scout (https://scoutapp.com/) but there are plenty of open source options that are also used in various combinations (Monit, Nagios, Ganglia, ...) The free options will cover infrastructure status/history and basic service availability just fine. If you need more advanced features like performance management, troubleshooting, and inputs for capacity planning, you might be better served by the paid applications. As far as scaling goes, there was a series of videos and podcasts done a few years back called Scaling Rails (http://railslab.newrelic.com/scaling-rails) that describes a lot of the basic techniques used to improve performance. A lot of these have to do with caching and avoiding DB hits whenever possible. Beyond that though, I think it still comes down to good architectural practices like DB management, application layering and partitioning, etc. For my money, Cal Henderson's book Building Scalable Web Applications ( http://oreilly.com/catalog/9780596102357) is still the best place to start reading if you're looking for best practices for web applications in general. There was a Rails specific title dealing with scaling and deployment available a few years back that's now out of print ( http://pragprog.com/titles/fr_deploy/deploying-rails-applications). Design is too general. You'd need to be more specific about what you mean by that. Testing is an area that's taken very seriously with a lot of competing and complementary testing tools available. Get started with the official Rails guide to testing (http://guides.rubyonrails.org/testing.html) and then if you're interested in going deeper check out Rails Test Prescriptions ( http://pragprog.com/titles/nrtest/rails-test-prescriptions) and the Rspec Book (http://pragprog.com/titles/achbd/the-rspec-book).

[Rails] Service Management
I was just wondering if there was anybody here who'd worked in a Service Management environment (ITIL for example). I'm interested to know of tools for use with planning and managing availability, capacity, continuity and security in a RoR environment. Particularly the first two. How easy is it to scale RoR? Can you easily have multiple server instances for one service - if so, how do you do it, and what problems do there tend to be? How can you predict performance and capacity? I'm also interested in design and testing considerations. Much of the above is not, I know, of much direct interest to developers, but I'd hope that somebody has been involved with this! -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You are right. Catching and re-raising the exception is used if you want to do something when the exception happens but you don't want to fully handle the exception. For example, if you would like to log it but you don't want to be responsible for handling the problem.

Re: [Rails] Re: Help with find
For slighly more idiomatic Ruby, you could use the attribute name "active"
rather than "is active". The resulting query would then look something
like:
Province.joins(:cities).where(:active => true).where("cities.active = ?",
true)
