Hi, Rails 2.3.2 class TestD < ActiveRecord::Base default_scope :limit => 12 named_scope :limit, lambda { |num| { :limit => num} } end ruby script/console >> TestD.all TestD Load (0.7ms) SELECT * FROM "test_ds" LIMIT 12 => [] >> TestD.limit(14) TestD Load (0.3ms) SELECT * FROM "test_ds" LIMIT 12 => [] Any ideas why the default limit

I have a polymorphic thingy called fields and I need to on each and every model, so I''d like to do the has_many from the base class, like this... ActiveRecord::Base.class_eval do has_many :fields, :as => :model, :dependent => true end It fails with this no method error (class_of_active_record_descendant) /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.6/lib/active_record/

Hi, I was wondering if there is a way to skip the application of a named_scope to calls made in legacy migrations. I am working with some old migrations that include some data manipulation tasks, and my default scope is preventing those migrations from running. I''m trying to avoid editing those migration files with with_exclusive_scope. Thanks, -G -- Posted via

I think this is a bug. I declared a model with self.abstract_class = true and then tried to call save on it and it attempted the save. I think this should raise a "method not allowed" exception of some sort. Where is the Trac system that I would use to report this?

I have the acts_as_commentable and a bunch of others added to pretty much every model, is there a way to automaically add these to EVERY model ? I tried the following but it fails with an error...

Hi, Does anyone know much about abstract_class? Does it actually prevent instances of the class from being created? Does it disable certain methods? I already know what it''s for, but I want to know what setting self.abstract_class=true actually does. The reason I ask is that I want to use it for a slightly unorthodox purpose. I want a class who''s only attributes are its

Hello, I am trying to convert three applications to multitenant, all of them have same structure difference is only in little functions and template designs. All of them using cattr_accessor for setting currencies and other data, and it works perfectly Now i added app_id as cattr_accessor to App model to use it in default_scope to implement multi-tenancy class App < ActiveRecord::Base

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>".

Good afternoon, I am currently migrating an app from rails 2.1 to rails 3 and found a problem that I realized was due to the fact that the BD columns had reserved rails names. I only have read access to BD, so I can''t change the name of columns. The column in question is called "reference" and I''m having a very strange behavior during implementation: 1) initializing /

I often find myself in situations where I''m fighting against ActiveRecord because there is no easy way to alias some tables. For example, I''m converting a legacy application. So, there is a ''condition_type'' table that actually should be something like ''fields''. Also it can have a parent field and deletion is handled by setting a

Is there a reason why AM:S doesn''t support arbitrary keys to serialization? I can see a lot of uses cases where arbitrary keys could come handy. Right now, if one tries to do it, AM:S checks if the keys match a method of the model and raises exception if it can''t find any. class Client < ActiveRecordBase attr_accessible :name, :address, as: :creator include

I want to create an internal admin view to display the output of "show variables" from mysql. What''s the best approach do this?
