similar to: Overloading ''find''

Hi, i was wondering if there was a nice clean way(after all, it is ruby) to change the find method of a certain model/class (Page) so that if i wanted to use a find method on a @page instance it would return only specific rows from the table(if the page.published == true/false: the pages table looked like SQL: ... id int not null auto_increment, published tinyint(1) not null, something

I''ve got 8 scaffolds, each one can be considered an ''item'', such as a blog, photo, etc. Using login_engine and user_engine, I list all blogs belonging to a user by saying: @user=session[:user] @blogs=@user.blogs.find(:all) but then let''s say I want to create an option where I want to slice it differently: @user=session[:user] if @someOption ==1

Hi, I''m writing this app with inheritance. I''m using the type column to store the class name. Another app scans the app and performs actions. However, it is possible that the second app does not implement a class, in which case, the superclass should be instantiated. Now I''m getting: /opt/local/lib/ruby/gems/1.8/gems/activerecord-1.14.2/lib/

When testing my app locally I''m getting intermittent errors which are driving me mad! The error is: NameError ((eval):1:in `alias_method'': undefined method `destroy_without_callbacks'' for class `Exercise''): Refreshing the browser sometimes fixes it, as does restarting WEBrick. Annoying to debug as it only happens intermittently. Any ideas on why this is

So after recompiling ruby a few times to get ssl and readline working, fighting with lighty for awhile, and learning a bit more about linux in the process, I think I''m really close to getting i2 up and running. However, when I try to access my wiki, I get either a blank page or an error 500 and the stack trace below gets sent to the log. If I can''t get this working soon

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

Guys, I am trying to figure out what exactly does this line do at the end of "acts_as_paranoid" plugin? ActiveRecord::Base.send :include, Caboose::Acts::Paranoid::ActiveRecord My problem: I have some classes that I use acts_as_paranoid, and others with tagging support. Classes declared as taggable, throw error, which appears to be in the acts_as_paranoid version of the

ciao a tutti.     come al solito, sto andando avanti a piccoli passi nel creare l''applicazione depot del libro "Sviluppare Applicazioni Web con Rails". Ora mi trovo nella fase di creazione dei test automatizzati. Ma c''è una cosa che proprio non capisco: Ho la seguente classe in ~/depot/test/unit/product_test.rb require File.dirname(__FILE__) +

Howdy, I have a model I called ''content_series''. I created it and noticed that Rails called it ''Sery'', so I added ''series'' to the uncountable thing in the config, like this: Inflector.inflections do |inflect| # inflect.plural /^(ox)$/i, ''\1en'' # inflect.singular /^(ox)en/i, ''\1'' #

Trying this straight from the README: I have acts_as_paranoid in my model (Course), and added the deleted_at column. This is OK: Course.find_with_deleted(:all) Course.find(:all, :with_deleted => true) gives: ArgumentError: Unknown key(s): with_deleted from /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/ active_support/core_ext/hash/keys.rb:49:in `assert_valid_keys''

I''m having problems unit testing my model- I have a kind of quiz functionality user table and a question table and a user_question_response table that contains the id for the user, the id for the question and the user''s response. The user_question_response has it''s own model belongs_to/has_many with users and questions and it works fine in the actual application but

Hi, This is just kindof a RoR question, but since you all potentially do the same things as I do, I thought I''ll ask here.. Im trying to use the boolean type in the database. Migrations is no problem, it even converts the 0/1 values from my import CSV to false and true. However, I cannot make the :conditions part of a find work: Loading development environment (Rails 2.0.2) >> c

Hi list, Is there a better/simpler way to code an inner join, than the 4 lines below: class Day < Foo def self.find_all_with_appointments (*args) find :all, { :select => ''distinct foos.*'', :joins => ''INNER JOIN appointments ON days.appointment_id = foos.id'' }.merge

Hi, I want to share some helpful code snippet. Can it further be optimized? Or is this even good to do? Put this in your model to write a customized find method having more conditions: def self.find_active(*args) options = extract_options_from_args!(args) conditions = "AND (#{sanitize_sql(options[:conditions])})" if options[:conditions] options[:conditions] =

Hi, I''m new to Ruby/Rails and trying to do something like: options = { :select=>''t1.*, count(c2)'', :joins=> ''AS t1 LEFT JOIN t2 ON t1.ID=t2.t1_id'', :group=> ''t1.id'', :having=> "count(c2) = #{my_var}" } T1.find(:all,options) But I got the following error: ArgumentError in T1Controller#action1 Unknown

If I pass a date through date_select to a controller, can a Active Record object be found based on this date that is passed?
