similar to: initialising an instance variable on ActiveRecord creation

I''m trying to be a good rails developer and fix DRY violations as i find them. However, i''m trying to fix this one, i cant seem to get it to work. I have two tables A and B that have a one-to-one relationship. Table B belongs_to Table A. Table A has_one Table B. I''m creating instances of Table A in different places, depending on the controller. However, for each

Running into an interesting problem that at first glance appears to be a bug in the AR association code. However, it''s explicitly coded this way so I''m not so sure. I have some code like this: class Address < ActiveRecord::Base belongs_to :addressable, :polymorphic => true end class Person < ActiveRecord::Base has_many :addresses, :as => :addressable,

Hi all, I have a problem with acts_as_rateable in rails 2.2.0. [code=]ActionView::TemplateError (uninitialized constant <#object>::Rating) on line #10 of app/views/blah/blah.html.erb: /Library/Ruby/Gems/1.8/gems/activesupport-2.2.0/lib/active_support/dependencies.rb:102:in `const_missing'' /Library/Ruby/Gems/1.8/gems/activerecord-2.2.0/lib/active_record/base.rb:2042:in

As great as Rails 2.1 is, I for the life of me cannot figure out why polymorphic associations do not support reconfiguring the type column used. For example, I have no way to do a polymorphic association using a lookup hash which maps an integer to a class name. Storing a TINYINT unsigned is waaaaay more efficient than storing a string like "SomeActiveRecordModel" over and over again.

I am trying to do something right from Agile Web Dev with Rails book and it does not work. I must be missing something obvious. I have a one-to-many relationship: class Draft < ActiveRecord::Base has_many :endorsees end class Endorsees < ActiveRecord:: Base belongs_to :draft end >From my reading, methinks I should be able to say: d = Draft.new d.endorsees << Endorsee.new

For some reason rake spec is totally crapping out on me. I don''t know what I did to make it break, the only thing I tried new was install haml, but even after removing it there is still a stack trace. Here is what I am getting- sparta at phalanx ff $ rake spec (in /Users/sparta/Projects/work/idastudios/ff)

Hi, Thanks for your reply. I just came up with another question about a similar but different thing: Say I have a bunch of data.frame variables named P1,P2,P3? I want to assign them row names according to symbols in the first column, and I want to do this using a for loop. How could I accomplish this? for (test_sample in c(1:10)){ +

I can submit a patch, but wanted to confirm I''m looking at this right... The docs indicate that if you specify a has_many association with :finder_sql, but no :counter_sql, it constructs the appropriate counter sql by substituting the SELECT clause. But has_many_association.rb doesn''t seem to do that -- it just passes Base#count_by_sql the finder_sql, which doesn''t

Hi, I have a strange problem that only occurs on the production server. I''ve been banging my head for hours trying to figure it out with no success. Below is a copy of the error from the production log.

Hi, I spot weird behaviour of latest Firefly 3rd party on my laptop. Sometimes it comes to state that it won't start (hangs on "Initializing" ) and it again works after system restart... Didn't yet figured out how to recreate it..... Any similar experience ? Also - how can I force Firefly to make outgoing calls (also sip or iax calls) through Asterisk ? I'd like to

Hi, It seems to me that the Mersenne-Twister PRNG can be initialised using one integer instead of 624 integers, since inside RNG.c code there's a function defined as MT_sgenrand(Int32). How do I actually set this seed within R? I've tried: > .Random.seed <- c(3, 1) > runif(1) Error in runif(1) : .Random.seed has wrong length In addition, is '3' actually the

Are there any plans to allow us to specify UPS variables in ups.conf, eg: [evo_s_3000] driver = usbhid-ups port = auto desc = "Eaton Evolution S 3000" vendorid = 0463 productid = ffff ups.delay.shutdown = 120 ups.delay.start = 130 The reason I ask is that I'm using FreeBSD & gmirror and need to extend the gracetime

I installed WPO2000 on RedHat 7.2 - it worked fine for a while. I used the updated install scripts and Mr. Torrie's CorelWine rpm. It has been working fine for a couple of weeks (and continues to do so on another machine). Now when I start the WP application, I get a window that says "Wine initializing...", then it goes away (a little too quickly, I think), and then...
