So, I have a User has_many :profiles. The most recently dated profile is considered the current one. I need to sort these users by name, but the name attribute is a member of the associated table. Is there any easy way to do this other than with some ugly find_by_sql? Maybe a more general question - is there a common solution to sorting in Ruby? -- Posted via http://www.ruby-forum.com/.

Hi all - I''d like to implement a lookup table in my app that contains some reference data, just some status codes and their descriptions. What''s the most appropriate approach according to the "rails way" of doing things? Would I just implement a has_many relationship? Let''s say these are Order status codes, would the StatusCode have many Orders? This

Sorry, that name is a misnomer. However, I was excited to find that Ruby has a built in Observable module and I''m pretty bored, so I apologize in advance.... require ''observer'' # one who is observed class Celebrity include Observable attr_accessor :name attr_reader :is def is=(val) @is = val changed notify_observers(self) end end # one who

I have a simple method in a model, to send out e-mails via the script/runner. def Reminder.dropoff @messages = Reminder.find(:all, :conditions => [ "time < now()"]) @messages.each do |mes| Mailman::deliver_send_message(mes) end end However, it''s not sending e-mails. When this exact code was dropped in a controller, it worked great... is there

So, I''ve written a partial that does some stuff with a given instance of my class "entity". Entity is ActiveRecord. I''m able to retrieve all sorts of data from an @entity, until I do something like: <% for @attribute in @entity.attributes %> <div id="attribute_<%= @attribute.id %>"> <%= render(:partial =>

For a really long time, I''ve been using DBDesigner from FabForce.net. For those of your who''ve never used it, its a freeware visual entity-relationship diagram tool, which allows you to make database designs visually instead of in SQL DDL. You can then use it to generate the SQL to make your databse design into reality, or even run a "synchronize" to make any

Hi, I'm needing some help finding a function to read a large text file into an array in R. The data are essentially presence / absence / na data for many species and come as a grid with each species name (after two spaces) at the beginning of the matrix defining the map for that species. An excerpt could therefore be: SPECIES1 999001099 900110109 011101000 901100101 110100019 901110019

If I browse to \myRoRApp, I get the "Welcome aboard" screen. I''ve done the ruby scripts/generate controller MyTest, and "Rolling with Ruby on Rails" tells me I should be able to browse to \myRoRApp\MyTest and see an error page, but what I''m actually seeing is a fastcgi config file! I have installed fastcgi, but apache can''t "see" the

Bad rails day for Matt- In a migration, for a habtm: create_table :teams_users do |t| t.column :team_id, :integer t.column :user_id, :integer end Ok, fine. In a controller (well really a migration script): @user.teams << Team.find( 3 ) And the SQL pumped at my server is: INSERT INTO teams_users (`team_id`, `id`, `user_id`) VALUES (3, 3, 34) Which

So this new STI :through thing is still not clear to me. I have a project now where I''m using this: class List < ActiveRecord::Base belongs_to :user end class StaticList < List has_and_belongs_to_many :items end In the script/console: >> StaticList.create NameError: uninitialized constant StaticList What? ok, fine. So a List.create would be in

Hi. I'm trying to perform what should be a reasonably basic analysis of some spatial presence/absence data but am somewhat overwhelmed by the options available and could do with a helpful pointer. My researches so far indicate that if my data were normal, I would simply use gls() (in nlme) and one of the various corSpatial functions (eg. corSpher() to be analagous to similar analysis in SAS)

Hi everyone, I've been having difficulty writing wrapper functions for some functions where those same functions include other functions with eval() calls where the environment is specified. A very simple example using function lmer from lme4: lmerWrapper <- function(formula, data, family = gaussian, method = c("REML", "ML", "PQL", "Laplace",

Does anyone know of a good package that can convert a PDF into HTML? Cross-platform compatible is a plus, but I can live with Linux-only if it comes to that. -- Posted via http://www.ruby-forum.com/.

Hi, If I include a javascript library, will it load when the html load, or just at the first use? I have table.js and I have few pages that needs it. Should I include it just on the pages that needs it, or put it on the application_layout? Thanks, Kfir

Hi, I have a ''descriptions'' table which has_one of lots of other tables. The other tables all belong to a description. But I only want each description to have one record from any of the tables. So a description can''t have a room and photo. There has to be one description for each room, and one description for each photo. Any idea if there''s a reasonably easy

Hi there, we made a PHP and Impakt2 based web content management system for schools with specific features that work really well for schools. The way I designed it was so there was one central set of source code and an empty (in terms of rows in tables) database structure. To set up a new school i had a script that basically created a new directory in /var/www and then within that, symlinked

Hi all, I''m trying to get rails up on mssql for a friend, does anyone have experience? We''re working on a Windows XP box with MSSQL 2000 (no service pak), and both rails (1.1) and MSSQL are on the same box. I''m running into a bug (I think) where activerecord is using this syntax: SELECT TOP 1 * FROM users WHERE (users.user = ''jbgnuumnbu'')

Is there anyway to make Rails NOT cache? I''m getting caching in the browser and the server. I have to restart Lighttpd after every view change to see the results. Thanks, phill
