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

"Object is the root of Ruby''s class hierarchy. Its methods are available to all classes unless explicitly overridden." Wouldn''t Class class be at the root of the class hierarchy? After all, look at this: 1.9.2p290 :006 > Object.instance_of? Class => true Object is an instance of class, after all we can use one of Class'' instance methods on Object:

append_features(mod) The documentation says: When this module is included in another, Ruby calls append_features in this module, passing it the receiving module in mod. Ruby’s default implementation is to add the constants, methods, and module variables of this module to mod if this module has not already been added to mod or one of its ancestors. See also Module#include. What if this module is

Hi all, I am using rails 3.1 and ruby 1.9.3,Now i want to use uuid concept in rails 3 for existing data so i did like :- create_table :posts, :id => false do |t| t.string :uuid, :limit => 36, :primary => true end ActiveRecord::Base.class_eval do # old rails versions set_primary_key ''uuid'' before_create :generate_uuid def generate_uuid self.id =

We''ve been running into problems with ferret indexing lately. The problem is intermittent and some times it persists. Just got this after wiping the index and redeploying: NoMethodError (undefined method `add'' for Solution:Class): (druby://10.1.65.87:9009) /data/releases/20071111152414/vendor/rails/activerecord/lib/active_record/base.rb:1238:in `method_missing''

Is there a way with ActiveRecord to get ahold of a collection containing each association? I want to write a rake task that will dump a model and all its related models to yaml.

I''m having a problem converting a date retrieved from my MySQL database and I''m hoping someone can help. MySQL stores the date/time as this: 2005-03-08 17:00:34.0 and according to my Pickaxe book Ruby stores times as "the number of seconds and microseconds since [...] January 1, 1970". All well and good. Unfortunately, RoR is converting my date to this:

In the example below, what is the dash doing between the class attribute and array: (field_helpers - [:label, :check_box, :radio_button, :fields_for, :hidden_field, :file_field]).each do |selector| -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi, it would be nice to be able to specify workers as singletons. By this I mean that every call to the new_worker method returns the same instance of said worker. This can be done transparently either by adding a new argument to new_worker (something like :singleton => true) or adding a new method, like I did in my installation of BackgrounDrb: def get_worker_by_class(klass)

OK, call me crazy, but am I the first one to want to list out the actions that are available @ runtime? Anyone else come across this yet? Am I crazy? Well, yes, but... -- Posted via http://www.ruby-forum.com/.

Hi folks. So I''m using mocha on a ruby project, and I really like it. One thing I''ve noticed is that it can be a bit "surprising" when I''m mocking methods that don''t exist on an object, and I think there''s an easyish fix. At the moment, you use sheep = mock() to create a mock sheep. What I''d like to do is something like sheep =

Hello! So, my problem is following. I have bird offspring growth data and I'd like to model individual growth curves (aim is to study asymptotes and inflection points) with nlme according to Pinheiro & Bates 2000: first using nlsList to generate individual curves and then nlme to study the parameters and fixed effects. The data is structured to two levels. I have broods and

I''m wondering what''s the difference between stub and message expectation with any_number_of_times, for example: myMock = mock("mymock") myMock.stub!(:is_a?).with(MyClass).and_return(false) and myMock = mock("mymock") myMock.should_receive(:is_a?).with(MyClass).any_number_of_times.and_return(false) because is_a? may not be called at all, it just like a

I have a model where I need to calculate one of the fields when I create a new instance. It seems to me that I should do this in the model code and that I should override the new and/or create methods. Is this the right approach and, if so, how can I execute the existing method but add on my calculation? I want something like: def create -Do the original create first- field =

Hey all, There''s a core Class class and core Object class in Ruby library: http://www.ruby-doc.org/core/classes/Object.html http://www.ruby-doc.org/core/classes/Class.html First, let''s resolve the simple distinction between an Object and Class as envisioned by Smalltalk but within the Ruby context: #A class is a template used to define methods and properties class Hello

I haven''t had a chance to work on fixing multiple controller view paths recently. My original patch attempt was: http://dev.rubyonrails.org/ticket/8582 It was rejected due to the fact that it was fixing the symptom more than the problem. However, I think it''s critical that this problem get fixed, otherwise the whole concept of view_paths is severely neutered and

Hi folks. I''ve just started using rspec and I have to say it''s very nice. The thing is, I prefer mocha''s mocking dialect. So I thought a simple require ''mocha'' would set me up. Unfortunately, rspec does all its goodness using do/end blocks in anonymous classes, so it wasn''t quite that obvious. Anyway, here is the incantation I ended up

Hi! I''m trying to extend ActiveRecord''s find method (Rails 1.0, Ruby 1.8.2), but I recognize a strange behaviour of the "alias_method" call. I wrote a very simple script to explain my problem: ------------------------------------------------------ module ActiveRecordExtension def self.included(base) base.extend(ClassMethods) base.class_eval do

Hi, there. I have two validations in the model: validates_numericality_of :value, :only_integer=>true, :allow_blank=>true validates_size_of :value, :is=>9, :message=>"must be 5-digit number", :if=>Proc.new{|u| u.value.is_a?(Numeric)} They work as expected except when the :value is character/string like "a" "abc", the second validation will also output
