similar to: Looping through all models in the application

Hello. I have a program that accesses a metadata (translation) table for column names as well as the ordering of columns for a specific model. Also in there is a collection of bool options such as column_visible_on_form, column_visible_on_screen_quicklist etc. The idea is that our customer can specify to a certain extent how their layout/user interface will appear. To accomplish this, I use

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

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, my mongrel has crashed with following errors in the logfile: ** Starting Rails with development environment... ** Rails loaded. ** Loading any Rails specific GemPlugins ** Signals ready.

ActiveSupport provides a method Object.subclasses_of, shown below: def subclasses_of(*superclasses) subclasses = [] ObjectSpace.each_object(Class) do |k| next if (k.ancestors & superclasses).empty? || superclasses.include?(k) || k.to_s.include?("::") || subclasses.include?(k) subclasses << k end subclasses end Can anyone shine some light on why

Hello, I''ve been working for a few days on a problem which, after tracking it down, seems to be related to unicorn. I''m hoping that somebody might be able to help with information about what''s going on. In the Rails 3 application that I support, we sometimes fork during a web request in order to do background processing behind the scenes without the user (and the

Hi I''ve migrated from Passenger to Unicorn about a week ago. It''s great. Great transparency and management, thanks for this great software! A few of my Rails applications start background jobs using Kernel#fork. Of course, the ActiveRecord connections are closed and reopened again in the parent and child processes. The child process also does its job. Unfortunately, it seems

Hi, I''m trying to write some methods which use a parameter to represent a Class name. A very simplistic example: def foo(class_name, conditions) x = class_name.find(:all, :conditions => "#{conditions}") end Unfortunately, this does not work. The only way around this problem that I can think of is to use eval: def foo(class_name, conditions) x = eval

Can any one tell me if Rails has a max file size upload limit? and if so what is it and can I change it? Cheers. -- Posted via http://www.ruby-forum.com/.

Has anyone managed to replace ActiveRecordStore::Session with their own model? In the source (http://dev.rubyonrails.org/browser/trunk/actionpack/lib/ action_controller/session/active_record_store.rb) it says you can override the default by setting CGI::Session::ActiveRecordStore.session_class = MySessionClass I have tried doing this in a number of ways but I get all kinds of weird errors, as

Hi, I would like to put a checkbox on a form where the input field is a variable rather than a field in a model. The normal way (with a model) would be: <%= check_box(''client'', ''accept'', {}, "1", "0") %> But since accept is a variable @accept and model client will not be there, how do I make a check box work? Regards, Paul

I just got the Rails Recipies and I''m looking the Recipe 17. class Person < ActiveRecord::Base has_many :addresses, :as => :addressable end class Company < ActiveRecord::Base has_many :addresses, :as => :addressable end class Address < ActiveRecord::Base belongs_to :addressable, :polymorphic => true end At the beggining I had some problems because

Hello, I created a table and about 10 migrations down the line I decided that I needed to add an ID column (this was actually a table for a has_many :through and I recently realized that it needs an ID column, unlike HABTM tables). I am a big perfectionist and I frequently run "SHOW COLUMNS IN table;", so I naturally expect to see the "id" column the first one listed. However,

hi! im trying to implement a role based authentication in my project, but im writing too many conditions, and i think thats not the right way to proceed. i have search in google, but there are a lot of plugins and "tutorials", and they are always not similar, so i dont understand them. please could someone help me? maybe with a easy authentication or with a good/nice tutorial?

How can I get the sessid from the current session object? For instance, I log in the system, and want to know which sessid I''m using. I''m storing the session using active_record. Later on, I want to restore a session finding it using the sessid. Thanks in advance. Fernando Lujan
