I have two tables: class PgmUpdate < ActiveRecord::Base has_many :pgm_visits, :foreign_key => ''pgm_update_fk'' ... and class PgmVisit < ActiveRecord::Base belongs_to :pgm_update, :foreign_key => ''pgm_update_fk'', :dependent => true ... According to the has_many docs (http://api.rubyonrails.org/classes/

I am trying to optimize some methods in my model so they don''t repeat CPU intensive algorithms every time I call the method in the same request/response cycle. Eg. ================ def invitations all_pgm_updates.find_all do |update| update.invited? end end ================ I want to do something like: ================ def invitations if @invitations.nil?

I have a pretty complex model with many modules and I have been trying to keep it clean, but I find that loading the model in development mode using WebBrick is much more lenient than production mode with lighttpd/fcgi. For instance, if I neglect to create a dedicated file that declares the module then I run everything in development mode it works fine, but as soon as it is deployed I

I got Capistrano working with one of my Rails projects, but I intend to use identical models in a second project. I originally was using a symlink to point to the other models, but I want to be able to use the same ''rake deploy'' command for the two apps individually so I don''t have to deploy both together all the time. Any ideas? -John -- John Smilanick

I have a class that has_many :visits, I want to search through the visits to get only ones that are committed: I thought it would be as easy as: ================== visits.find_all do |visit| visit.coming? end ================= but this always returns the entire list of visits. The only way to get it to work is to put the visits into a new array first: =================

class PgmUpdate < ActiveRecord::Base has_many :pgm_visits ... class PgmVisit < ActiveRecord::Base belongs_to :pgm_update ... I am trying to make sure that none of the visits in PgmUpdate overlap start and end dates. Should this validation exist in PgmUpdate or the controller? It seems natural to put them in PgmUpdate, but I must force the relationship together because

I am using the Openbase adapter and have had a similar glitch here and there, but after I go into production I consistently get an error on one page. ActionView::TemplateError (NoMemoryError: failed to allocate memory: SELECT * FROM ... I cannot track down the exact location of the error, but the production log says it was around:

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 =

I''ve got a Cuisine and a Restaurant model, with a habtm. One thing I want to do is find all the cuisines that have at least one restaurant associated with them.

The controller is under: app/controllers/admin/my_controller.rb The my_controller.rb file looks like this: module Admin class MyController def index render :text => ''Hello!'' end end end How does a route to all controllers under module

I''d like to announce acts_as_habtm_list plugin for rails. acts_as_habtm_list is a Ruby on Rails plugin, that can manage ordered lists through a join-table. It is providing almost the same Api as acts_as_list. The position column has to be defined in the join table. You can find additional information at: http://www.inlet-media.de/acts_as_habtm_list/ Install it executing this command

On my host I run my lighttpd instance bound to a specific port and my hostname is mapped to this port (I''m not exactly sure how this is accomplished, but it is lighttpd also listening on port 80 which handles this for me I believe). A redirect from rails includes my local port number in the request, so that it shows up in the address bar. I prefer people not to see this - I

Hey, I have users entering URLs into my app, is there anyway in which I can check to see if the URLs actually point to something before saving the user input? Maybe a kind of ''ping''-action that returns true on success? (btw: does anyone of a tentative release date for Rails1.1? I''ve been slobbering all over my RailsRecipes book and I can''t wait!
