similar to: extending an active record model with obj.extend(Module)

Hi list, I''m trying to figure out the best way to add some functionality to active record. I have a table of files, and need to write a set of core functions that do different things depending on the type of file eg: class file < ActiveRecord::Base def resize ....does stuff end end the problem is the "....does stuff". For example, if the file is an image it

I have three model objects: 1. Document 2. Section 3. Content According to my requirements a Document must have at least one Section. Similarly a Section must have at least one Content. How can I add a Section when a Document is created and add a Content when a Section is created? My code: class Document < ActiveRecord::Base has_many :sections end class Section < ActiveRecord::Base

Hi, I''ve started to implement page caches but I''ve hit a brick wall getting a sweeper to clear the cache when needed. It seems that any models that I tell it to observe aren''t being observed properly. If I add the sweeper to a controller the initialize method runs, but no matter what I do the after_save/after_update callbacks aren''t running. Also if I try to

Hi everyone, I''m looking for a shortcut to finding and updating or creating record depending on the results of the find. So, is there a shorter way to do it than this? @stuff = Stuff.find_by_foo_and_bar("yay","hooray") if @stuff: Stuff.update(@stuff.id, {:foo => "boo", :bar => "hoo"}) else Stuff.create({:foo => "boo",

Hi, Two questions: 1 - Say I have average speed and directions for tide and I would like to plot them on a polar plot, but with different colors so I can indicate the two directions. I'm using polar.plot from the plotrix library. How can I add a second "b" and "dir.b" series to a polar.plot? library(plotrix) a = 3 dir.a = 85 b = 4 dir.b = 250 polar.plot(a, dir.a, start =

All, I''m wanting to initialize an ActiveRecord object. I understand that there is a method called after_initialize that appears to get called right after the ActiveRecord object is instantiated. Is after_initialize a Ruby thing or a Rails thing? Where is after_initialize documented? Can I pass parameters to it? If so, how? I want to initialize the "belongs_to" attribute of

Hi, I''m using activemerchant and setting up a class variable using config.after_initialize. It works great for the first request, but then the variable is nil. config.after_initialize do ActiveMerchant::Billing::Base.mode = :test OrderTransaction.gateway = ActiveMerchant::Billing::PaypalGateway.new(...) end I''m assuming this is is due to the model reloading after each

I have had a visit from our windows buddy the BSOD twice in one day when running R1.6.2 under ESS5.1.24 on a win2000 platform. I wasn't doing anything special, just moving or resizing the emacs window, although I did have 4 or 5 emacs windows open at the time. Has anyone else observed this problem? Thanks, Darryl.

All, I have a quick question - is the purpose of implementing after_initialize to allow custom attribute initialization for AR descendants? I have been overriding initialize whenever I require custom setup of my model classes, like so: def initialize(attributes = nil) super self.Status = ''G'' end So I have a couple of questions: 1) Could I achieve the same

Hi everybody I would like a function as the "before_save" method in the model. But it must be the opposite. When I take out data from the database through the model, I want to call a function before the data are available in the controller. Can anyone help me? ---- >>>> thx <<<< ---- -- Posted via http://www.ruby-forum.com/.

I have a hard disk full of live shows. Each show is in an individual folder (titled by name and date of show), and contains the individual wav files of the show, labeled "disc1track1, disc1track2, etc." It's the same naming scheme in each of the 200 or so folders for each show. I want to convert each audio file to flac - is there a way to do this all at once? I can't just

I''m trying to use redis-store as my cache_store. I also have an app_confirg.rb initalizer which loads a yaml file for config settings. In my redis.rb initializer I have: MyApp::Application.config.cache_store = :redis_store, APP_CONFIG[''redis''] However, this doesn''t appear to work. If I do Rails.cache in my rails console I can clearly see it''s using

Could someone point me in the right direction for the following issue: A function is defined as follows: tfun <- function(dat) { fmla <- as.formula("y~x+z") dat2 <- dat mdl <- lm(fmla,dat2) mdl <- step(mdl) } Then the following code dat <- data.frame(x=1:10,z=1:10,y=(1:10)^2+10*(1:10)) tfun(dat) generates the output Start: AIC= 43.67

I have the following models: class Order < ActiveRecord::Base belongs_to :billing_address belongs_to :shipping_address accepts_nested_attributes_for :billing_address accepts_nested_attributes_for :shipping_address, :reject_if => proc { |attributes| attributes[''has_shipping_address''] != ''1'' } def after_initialize self.build_billing_address

I have a case where I am abstracting the creation of models. After a fair bit of indirection, I eventually get around to making a .new call. I need to be able to pass params to that .new call. I know I can''t use def initialize() in an AR model (rather frustrating). So, I have found some references to after_initialize, but that doesn''t work either. I see several threads on

All, Can anyone see what''s happening here? ================== migration ======================= class CreateGreetings < ActiveRecord::Migration def self.up create_table :greetings do |t| t.string :greet t.string :language t.integer :count t.timestamps end end def self.down drop_table :greetings end end ================== greeting.rb

Hi all, Just had an interesting production failure while updating my Rails application - a bunch of code previously in config/environment.rb was put into config/initializers. That resulted in me having to wrap some code in config/environments/production.rb into an after_initialize do ... end block When backgroundrb was run against that code, the setup done in that after_initialize block

In Rails 3, is it possible to have a plugin inside an engine? Adding the lib dir of the plugin to autoload_paths doesn''t seem to work. I can manage to load it by adding that path to $: and requiring the init.rb file, but I''m not sure that''s the correct approach.
