I need to create a sort of transaction around some Active Record objects that perform many insert/updates. Example: class MyObject def transaction &block @my_var = value self.instance_eval block end end MyObject.new.transaction do Model.create Model.collection.create etc...... end I have a gem that add a method into AR::Base and I need to read

I am serializing a data object (FooData) into an ActiveRecord column (Foo). I''d like to be able to do delegate methods to the data class if the Foo class doesn''t have that attribute. So instead of: f = Foo.new f.data.item1 I''d like to do: f = Foo.new f.item1 I was hoping that I could add a method_missing method to my Foo class and call methods in the FooData class

i''m using method_missing to implement a simple metaprogramming that checks for account rights. in Account << ActiveRecord::Base i defined: def method_missing(m, a = {}) if m.to_s =~ /^has_right_(.*)$/ ... calls another method passing $1 parameter end end it seems to override some of the active record methods based on method missing. in the console it seems to work ok so i

I have a site (for an academic conference) that I want to convert to RoR - both as a learning exercise and to ease further updates and development. There are a number of child pages for each conference (past and future), but these pages are different for each conference (not same child pages for each conference). The URLs are along the lines of: /conference/2000/keynotes

This SystemStackError is driving me crazy. It only takes place when testing with WEBrick - I can''t reproduce it with any tests. It is caused by calling the "missing" id method (base.rb:2435) on my ActiveRecord class. WEBrick and my tests are running as the same user, with a `ulimit -s` of 10240. Plus the query works sometimes so I don''t think this matters.

Any idees why I can do this: @sum = @selected.inject(0) { |sum, player| sum + player.value } but not this: @sum = @selected.sum { |player| player.value } @sum = @selected.sum(&:value) The last two give me following error: wrong number of arguments (1 for 2) /Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/associations/association_collection.rb:164:in `calculate''

I have a simple controller that takes a request, looks up some data and then returns the results as either HTML or Atom. The HTML response works fine, but the Atom Builder is blowing up with an undefined method error that I can''t figure out. It seems to be failing when the ActiveRecord instance is passed to the ''entry'' method and it tries to build the URL via the

Hi, I am getting a method_missing error when I run my application in the production environment unless I set config.cache_classes = false in config/environments/production.rb. This happens in Rails 2.2.2 but not in Rails 2.1.0. The method that is missing is one I used to have before I edited by hand the migration that creates the table associated with the object (I know you are discouraged to do

Is it possible to make a Rails app respond to a "dinamic" controller? As I understand method_missing can be used inside a controller to respond to nonexisting methods, is it possible to provide a similar behavior at a controller level? I am not sure at whic level would this code be inserted... -- An?bal Rojas http://www.lacaraoscura.com/ anibalrojas@gmail.com

Then if you do Post.limit(1).first << Author.limit(1).first You get an exception Author does not define :to_ary Or has there been a change in rails 3 that I have completely overlooked while migrating my app? -- You received this message because you are subscribed to

In my continued efforts to port my rails 1.x app to Rails 2.1.2, I keep running into what appear to be ActiveRecord bugs.
