similar to: exclude association option for ActiveRecord

Hello RoR Groupies, I''m seeing some weird ActiveRecord-2.2.2 SQL generation when doing eager association/preloading and using joins and ordering by said join table. Here''s an example: class Photo < ActiveRecord::Base end class User < ActiveRecord::Base has_one :headshot, :class_name => "Photo" end class Mail < ActiveRecord::Base belongs_to :user end

Hi - is there an easy way to submit an object with its associations as an :expects parameter to a AWS webservice? I know I could first create a webservice method for the object, and then call - in a loop - another webservice for each of my association objects. Is there an easier more elegant way, so that I don''t have to make so many expensive webservice calls? I was thinking

We have been using more and more Ror for new applications. Right now we are debating on the best way to implement some new webservices that will interact with our payment gateway. These webservices will be backend type functions. Updating customer/billing records, retrieving data, etc.. The interface for actually processing transactions won''t be changing. Ideally, the webservice will

I''ve gotten eager associations to work before, but for some reason this isn''t working out for me this time. I''ve been scratching my head but can''t quite figure out the nuances of what works and what doesn''t work. I''ve got 3 models: profile, widget_configuration and widgets profile.rb -- has_many :widget_configurations

I am still using Rails 1.0... I have a simple has_many association: class Round < ActiveRecord::Base has_many :scores end class Score < ActiveRecord::Base belongs_to: round end When I do something like this (contrived for the sake of clarity): rr = Round.find(params[:id]) rr.scores.each { |s| logger.debug("object_id=#{s.round.object_id}") } I see a database query on

Hi all, Is it possible to do "eager loading" with polymorphic associations ? Ex : I have a Page model that acts as taggable. When I do Page.find(:all), I would like to retrieve all tags associated with a page. Thanks, Thomas. -- Posted via http://www.ruby-forum.com/.

Hello all, I still have a patch for #3438 (eager loading doesn''t respect association orders); it passes all unit tests, and has additional unit tests with full coverage. The patch is attached. == The Bug == Author.find(1).posts != Author.find(1, :include => [:posts]).posts if Author has_many :posts, :order => anything. This means that either one must avoid eager loading or

Hi, I have a strange problem while using WebService API which expects an ActiveRecord derivate. This is the code of the API ... ------ class HarvesterApi < ActionWebService::API::Base api_method :send_measurand, :expects => [{:measurand => Measurand}, {:eaiSystemName => :string}] end ------ ... and this of my Model ------ class Measurand < ActiveRecord::Base

Hi Folks, Troll trumps your existing ActiveResource mocking libraries like inbuilt HttpMock,Fakeweb or Webmock out of water. With Troll, ActiveResource mocking just works, some of its features: 1. Don''t need to mock calls at Net::HTTP level (which webmock,fakeweb do). Really, we don''t care what HTTP library ActiveResource uses, fakeweb and webmock bring additional complexity

I just now thought of this, and sure enough it works like a charm (at least so far in my limited testing): has_many :events, :dependent => :delete_all has_many :upcoming_events, :class_name => "Event", :conditions => "date > NOW()" The purpose of this is that it makes eager loading of subsets of associations possible without replacing all the magic of the

Hello everyone, I would like to eager load scoped records to avoid queries executed in a loop (huge performance impact). The "scoped" part is what is giving me a hard time. I''m using Rails3 RC. Does anyone have any idea how I can do it? Here is a test case : we have an "Article" and a "Comment" Activerecord models, article has many comments comment

Hi, I am trying to overwrite the accessor of a has_many association. Basically my class looks like this: class Person has_many :emails has_one :link, :class_name => ''PersonProxy'' def emails_with_link link.emails + emails_without_link end alias_method_chain :emails, :link end Now that works fine if I only access the collection like >>

Hi friends, i''m usgin the edge version because i need eager loading on polymorphic associations support, but i see this: Message.find(:first, :include => :owner) #This generate this query: SQL (0.000072) SET SQL_AUTO_IS_NULL=0 Message Load (0.000389) SELECT * FROM `messages` User Load (0.001070) SELECT * FROM `users` WHERE (users.id IN (1,2)) And this Message.find(:first,

hi, I found a bug in ActiveRecord association SQL INNER JOIN codes. in has_many, has_one, habtm and belongs_to queries the foreign key is determined from the table name of reflection and self. but that''s worng because if you use a global prefix or suffix for your tables the foreign keys will be in format of PREFIX_CLASSNAME_SUFFIX_id which is wrong, because it breaks the advantage of

Hello, Can anyone tell me if there is a package which will allow me to write a package in R, then publish the package using WebServices? The idea is that I want to be able to pass a data set into R, have R perform the calculations, then send the result back to either a .Net application or a LIMS BASIC application. So far I see many packages that allow R to consume WebServices, but I haven't
