I have a module as shown below and when I extend an active record to use it, I can not access the primary_key method. In a simple test program using a similar approach where active record is not involved, access to the class methods seems to work ok.

Observers will be no more as of Rails 4, farewell, never been much of a fan. However, I''m using it in one of my gems which enables model attributes for use with a WYSIWYM editor. The resulting markup is persisted, but in order to use it in a view, it has to be nokogiried in a helper which fragment caches the result. This cache has to be zapped once the model instance is either

I''m a recent convert to Rails and I''m working on a new project using Rails 2.3 (I''ll probably upgrade at some point when Rails 3 is in production and had a chance to bake the .0 bugs out). I''m going to use Redis anyway for caching important data, so I thought I''d use the redis-store: http://github.com/jodosha/redis-store But it appears the flash

Hi I have a panel dataset with large number of groups and differing number of observations for each group. I want to randomly select say, 20% of the groups or 200 groups, but along with all observations from the selcted groups (with the corresponding data). I guess it is possible to generate a random sample from the groups ids and then match that with the entire dataset to have the intended

I'm manipulating a large dataset and need to eliminate some observations based on specific identifiers. This isn't a problem in and of itself (using which.. or subset..) but an imprint of the deleted observations seem to remain, even though they have 0 observations. This is causing me problems later on. I'll use the dataset warpbreaks to illustrate, I apologize if this isn't in

Hi, I am starting to learn rails and I went through the guide and a couple of tutorials. Even though I understand controllers or at least I can use them I can''t see yet the whole picture. Why do you need several controllers for a single application? If a controller is just a class whose methods interface with models and views, why not have a single controller for the whole application?

Hi, I''m using an ActiveRecord::Observer to log users changing data in my application. However, I''ve noted that adding an item to a has_many relationship gets logged, but removing the item does not. That is: @product.users << user is logged, but: @product.users.delete(user) is not. I''ve dug into ActiveRecord and found that the underlying issue is that the

Rails Guides says: ...the UserObserver ... would be saved as app/models/user_observer.rb and registered in config/environment.rb this way: config.active_record.observers = :user_observer But the observer registration above doesn''t work because there is no ''config''.
