similar to: Why does Object.subclasses_of ignore subclasses within modules?

ActiveSupport provides a method Object.subclasses_of, to give the subclasses of a given class. However, it ignores any subclass within a module, so : class A end class B < A end Object.subclasses_of(A) # returns [B] module C class D < A end end Object.subclasses_of(A) # returns [B], even though C::D is also a subclass of A class E < C::D end Object.subclasses_of(A) # returns

Anyone know a pretty way to get a list of all Models? That is, a list of all classes which inherit from ActiveRecord:Base I can''t seem to figure it out! The best I''ve got is to list the /app/models directory... but, that is *dirty*. -hampton. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi! I want to do what subject say. Is there any elegant way to do this: ??? # Silence the log inside the block attached to the method call. def silence_logger orig= nil ObjectSpace.each_object(::Logger) do |logger| logger.info "-" * 80 logger.info "Quieting the log..." orig= logger.level logger.level= ::Logger::FATAL end yield

Hey :) I''m trying to create a method for making a sitemap dynamically. It works great for flat sites where you simply have your controllers in the app/controllers directory. In this case, I can extract the controller names like, @controllers ObjectSpace.subclasses_of(ActionController::Base).each do |obj| @controllers["#{obj.controller_name}"] = obj end However,

A recently committed revison of R-devel (47740) has introduced a new mechanism for ordering superclasses consistently, with related changes for selecting inherited methods. As part of the process, a function testInheritedMethods has been introduced that examines method selection for the relevant subclasses and reports ambiguities. Maintainers of packages that have methods involving multiple

I would like to get at all models in a rails application to be able to add a field to every one of them as part of a migration. Something like the following: Appmodels.each { |x| add_column x.table_name.to_s, :foo, :text } I understand I can get the table name using ActiveRecord::Base#table_name, but how do I get all the models into an array that I can use in the above manner? -- Cheers, Hasan

I recently upgraded to 1.8.4 to try out mongrel, and so far have been in a kind of hell where I can''t get my app working!

Anybody know how to get a list of all your model classes from a rails environment? I''d like to do something like "ActiveRecord::Base.subclasses" but that gives me: pcollins@horatio:~/proj/foobox$ script/console Loading development environment. >> ActiveRecord::Base.subclasses NoMethodError: protected method `subclasses'' called ... Anybody know how to do

Hello. I have an application that depends on a table/model (ModelInternationalization) that provides international translations in various languages for all the model/table and columns names as well as some other stuff (whether the column is visible on forms, dropdowns, lists, reports etc). I need to create a management interface for this translation stuff (the plaintext stuff, btw, will be

All, My apologies if this is a little long-winded and stream of consciousness-y :). SUMMARY: Why do we extend ActiveRecord instead of mixing it in to our model classes? Been thinking about my app''s models and starting to want to build something of a hierarchy. I have some commonality across 3 of my model classes and I''d liek to aggregate the behavior in a superclass.

Hi, my mongrel has crashed with following errors in the logfile: ** Starting Rails with development environment... ** Rails loaded. ** Loading any Rails specific GemPlugins ** Signals ready. TERM => stop. USR2 => restart. INT => stop (no restart). ** Rails signals registered. HUP => reload (without restart). It might not work well. ** Mongrel 1.1.3 available at 0.0.0.0:3000 **

Hi, I''m using an ActiveRecord::Observer to log users changing data in my application. However, I''ve noted that adding an item to a has_many relationship gets logged, but removing the item does not. That is: @product.users << user is logged, but: @product.users.delete(user) is not. I''ve dug into ActiveRecord and found that the underlying issue is that the

Hi, I'm working with Version 1.9.0 (2004-04-12) on Windows 98/NT/2000 where I found the following wrong (?) behavior of setValidity(). I already mentioned this on the R-help list (2004-06-11, was "setValidity changes Extends?") , but as I got no answer I tried to figure out what's happening. Well, setValidity() behaves not as I would expect (something about the

I've tested it on MSVC, gcc, clang and icc. The solution in clang (in Decl.h) is not ideal (as you have said yourself). The solution I offer, is using a union of fields of class BitField (this is a new class that implements a bitfield of a specific type requested). With this, the definition, of the required bitfields in the subclass data, remains in the hands of the actual class needing them.

I have a STI class tree. I want to set some default values (calculated values so I can''t set it in the database as defaults) on every created instance regardless of what subclass is actually instantiated. So I figured adding a after_create callback in the top class in the hierarchy should do the trick. It seems it doesn''t get called :( Code: class SuperClass <

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

Hello, I''m having problems using the widgets Wx::Http*, such as Wx::HtmlWindow, Wx::HtmlEasyPrinting, etc.. The error I got is "uninitialized constant Wx::HtmlWindow". The code is correct since I''m trying to execute samples in the html/ directory. All other samples work. I can''t even see that widgets doing require ''wxruby'';
