Hey everyone, I''m interested in extending ActiveRecord::Base. I have a special "easier" find function that I want to include in all classes. How can I include this in all classes? Can I just create a model object that does something like this: class ExtendedAR < ActiveRecord::Base def self.special_find ... end end and then all my other classes

Something is getting lost here. def create @home = Team.find_by_user_id(current_user.id) for player in @home.players player.update_attribute(:game_id, @game.id) end end def show @players = Player.find_all_by_game_id(params[:id]) end view <%= @players.size %> # mistakenly equals zero Played with the console and everything should be working fine...

Hello list, I''ve had this problem for two days now. Perhaps someone here would care to comment on it. I''d be REALLY appreciative if that''d be the case. Basically, it''s outlined at this paste: http://rafb.net/paste/results/ kXQSHZ83.html But I''ll paste it here, too. The main problem is in the customers/list action. The problem is with this line:

I have a form with contingent select boxes (the state is contingent on the country selected, so when the country selected changes, the state changes -- I am using the Carmen plugin for getting my state names and country names together, but not the functionality I am interested in achieving).

Hello. I''m trying to do the video tutorial "how to build a blog engine in 15 minutes with ruby on rails" from the main rubyonrails website, and I''m getting an error when I try to use scaffold :post after editing my config file for the mysql database.

Hi Hoping someone has had experience with this or can tell me where to start investigating. I''ve got a Rails app with Devise authentication running on a server cluster behind a load balancer, so requests to the website will alternately hit one server, or the other. My problem occurs when I try to register a new user. Everything goes fine, I get the confirmation email, I click the link,

I can''t get my view to display the most recent parameters from an associated object in a view... here is a birds-eye of my app: I have two models, Ferms and Kinetics. Ferm has_many :kinetics, Kinetic belongs_to :ferm. Kinetic has the fields ferm_id, brix and temp. In my ferms/index view I have a table listing the attributes of each ferm instance. I would like to display the most recent

Assuming you have Person that has_many :messages, what will it happen if it has 10000 messages? Will rails attempt to initialize @person.messages with 10000 rows from database? If that is the case, is combining finder_sql and counter_sql the common practice to avoid this? Bogdan _______________________________________________ Rails mailing list

Hi all I am new to Rails, and obviously I''m missing something, I''ll get straight to the question: A User has many operations (granted to her), each Operation is associated with an OperationType. Each Operation may be associated with more then one User. So the model goes like this: class User < ActiveRecord::Base has_and_belongs_to_many :operations

Rails documentation gives examples of using option_groups_from_collection_for_select with two tables/objects. How could it be done with one? Example that almost works: I have a form to enter address from both the United States and Canada. It has the following: ====new.html.erb==== <%= select_tag( :state, option_groups_from_collection_for_select( State.countries, :country,

Looking for suggestions on following two queries. Query 1 ------------------------------ Are the two following lines of code different in Ruby / Rails ( in a *.html.erb) file. <% if @forms.count != 0 %> <!-- first code --> Vs. <% if @forms.count %> <!--second code --> @forms is an array of objects.

Like the subject says, I''ve got a really weird problem. A co-worker added a couple of gems to our rails project.

Hi everyone, first post here in the forum. I''m usually in #rubyonrails on freenode. I''ve been thinking about the various types of caching, and I was wondering if its possible to have the server selectively send back data, instead sending nothing ''0'' if user has the newest data. My example is a presence monitor, and it seems like the logic is: - Rails caches
