Hi everyone, Does Ruby support variable variables like PHP (http://www.php.net/manual/en/language.variables.variable.php)? Or do I have to use eval, like some_hash.each_pair{|key, pair| eval "#{key} = #{value}" } Or is there some other way? I''m actually trying to figure this out in order to use ez_where to create its conditions from a hash, so if this isn''t even

I''m looking through the api for something like find(:all, :distinct => true) so that multiple instances of a row won''t be returned - is this possible? Thanks!

Hello everyone, I have the code below: paginator_options.merge!({:conditions => ''cities.id = 4'', :include => [:cities]}) @people_pages, @people = paginate :people, paginator_options There''s a many-to-many relationship between people and cities. It seemed like before this was working, but now in the sql that''s generated the join table isn''t

Hello all, I just ran into something that I think is a bug, and I would like to confirm with the core team whether this is expected/desired behavior or if this is a bug that I should file and develop failing tests for (I doubt I have the active record method_missing fu to actually patch it). Test Scenario: I would like to find or initialize a new user and base the find on the users email

I''m pretty much done with a project I''ve been developing to learn Rails, http://www.happycarpools.com . If you could take a look, that''d be awesome! Feedback would be even more awesome! Probably the coolest thing about making this has been seeing how Rails does *so much* and hardly has any superfluous parts, if any. There are so many features that I initially

I have two computers both of which are running Windows XP SP2. R 1.9.1 runs just fine on one but not the other. Both installations of R came from the same installation package. When I click on the desktop icon an hourglass shows up then disappears. Similarly, if I start RGUI the process shows up in task-manager then abruptly disappears. Interestingly, I can access R in Excel via the D(COM) Server

Hi everyone, It seems like every time I want to evaluate a possibly undefined variable I have to use defined? to see that it exists first, so I can''t simply have -- if params[:range_start] > 3 or something like it. I need to have -- if defined? params[:range_start] && params[:range_start] > 3 I can''t even have -- if params[:range_start].nil? This is really

Hello everyone, In my model, I have def leave_at_formatted leave_at.strftime("%I:%M %p") end I was wondering if there were any way to define to_s for leave_at in order to get the same result? Thanks!

I have two classes, Listing and Warranty. A Listing (think of it as a product) may or may not have a Warranty from a lookup table. When I want the Warranty.company for a given Listing I want to say the following: @listing = Listing.find(4) @company = @listing.warranty.company In order to do that I did the following: class Listing < ActiveRecord::Base belongs_to :warranty end and

Hi, I understand there are total 11 types of key Options for finding a record. The all 11 valid keys for the options hash are :conditions, :include, :order, :select, :group, :joins, :from, :limit, :offset, :readonly, and :lock. We also have Dynamic Finders for the same. e.g. ... find_by etc... I would like to know, how many types of dynamic finders, Active Record provides, to match all those

I have orders, order_items, and products. I want to collate several orders so that I can get a SUM of quantities ordered for each product etc. Can I say something like (the below gives an error on :sum, and ignores :group) OrderItem.find(:all, :sum => ''quantity'', :group => ''product_id'', :include => [:order, :product]) I want to get back a

Hi I''ve written ferret_helper.rb (FerretHelper module) containing wrapper methods for converting PDF, HTML, Open Document and Microsoft Word files to plain text for the Ferret index analysers. To help test it I wrote a simple ff.rb (Ferret Finder) command-line utility to index and search document files. You can download the code at http://www.methods.co.nz/ff/ Cheers, Stuart --

It looks rails automatically creates a "finder" method on models that have a "belongs_to". So I tried this in the console: c = Category.find(2) chunks = Chunk.find_by_category(c) chunks is always returned as an empty array. When I know have some chunks with a category_id of 2. Should the find_by_category do what I think it should be doing or am I completely off base?

Hi, I just uploaded a Rails plugin that allows you to specify custom SQL when doing a find with associations (AKA eager loading). One of the problems I encountered when implementing the Chacha Underground (http://underground.chacha.com) was being able to use queries provided by the DBA to efficiently get all the informaion I needed to render a page. In some cases, I needed to go two or three
