Hi! I just ran the first few Rails tutorials and I''m really impressed at how quickly I was able to get something up and running. I''m slowly emerging from the stone ages, and leaving my powerbuilder behind ? yes, I know, keep the snickering to a minimum please! I started into J2EE/STRUTS, but was quickly frustrated by how long it would take to code anything but relatively

I have two tables I am using single table inheritance with: Page and Item. "Page" has many "Items"; "Item" belongs to "Page". Item Model: class Item < ActiveRecord::Base end class Article < Item belongs_to :page end Page Model: class Page < ActiveRecord::Base end class Issue < Page has_many :articles end In my controller, when I

Hi all, I''ve upgraded my system to Rails 1.1.1 successfully. After much looking I haven''t found out how to migrate an existing application to a new rails version though. What is the procedure, if any, for upgrading the application I''ve developed in 1.0? Is there a script I need to run? -- Posted via http://www.ruby-forum.com/.

Hi, I need a relatively simple image api for the app I''m writing. I need to copy photos, rename them, and re-size them to put them in a standard format. I tried using RMagick/Imagemagick, but the photos would be corrupted on re-size, so I''m looking for some suggestions. -- Posted via http://www.ruby-forum.com/.

Hi, I have three tables, a domain of Sites, a domain of Users, and a junction of Sites_Users with the tables named as such. My RoR application has a model and controller both User and Site. I tried to add a controller and model named Site_User but I can''t reference any functions in the controller, I get an Uninitialized Constant error. I''m very new to RoR, but not to

I feel awful asking such a basic question, but here it goes.... I have a controller, "NewsController". The user enters and the "list" action is called and I populate an instance variable "@news" which contains all the elements I''d like to display using a form. The user then changes something and the "update" action is called. Is

I am getting the following error when running my app on the server: mysql::Error: Lost connection to MySQL server during query: <some SQL here> The SQL is usually a SHOW FIELDS statement, but after scouring the log files I see that it occassionally happens with other queries as well. I did a little research, and one topic I found suggested that I edit the /etc/mysql/my.cnf and increase

Hi: Sorry if this is a painfully stupid question... I have some data I need through the life of someone''s session. In the application controller, I grab the data and store it like so: session[:foo] = @foo Now, whenever I need to access data about foo I don''t need to cause any DB io, I can just grab foo from the session (it''s very small fyi). Here''s what I

I have chunk of data that I need for the life of the session. I am going to use it for selects through out my app. Is the best place to keep this data in the session? Is the session easily spoofed or cracked? While viewing the data is not critical in itself, spoofing it could cause me massive headaches. -- Posted via http://www.ruby-forum.com/.

I was up late last night trying to find the cause of this, but I''m stumped. I have this relatively simple controller to load up a bio. It''s basicly id, name, desc, type (I use STI). class BioController < ApplicationController layout ''layouts/singlepanel'' def index @bio = Bio.find(:all, :conditions => [''site_id = ?'',

I am trying to create a generic person model. Then subclass it as either a professor or an author. The only problem is that since some professors are authors, I don''t want duplicate entries.

I am going for a dedicated hosted server for a rails app I am working on, and have a choice from several different operating systems.

The app is Ruby 1.8.4, Rails 1.1.2, mySQL 5.0 The contestants are: Red Hat Enterprise 3.0 Red Hat Enterprise 4.0 Debian CentOS FreeBSD I''m leaning towards Debian,

Can a ruby on rails app obtain the ip of the server it is running on? I''d like the application to be able to determine x set of data is for y data, for example: These domains all point to the same ip... mydomain-1.com mydomain-2.com mydomain-3.org I can obtain the domain name from the request by using: @request.domain I''d like the application to grab the corresponding ip for

Right now rails doesn''t support composite keys, that is id1, id2, and id3 are in the primary key of the table. Does anyone know if this is being discussed for future versions, or is it pretty much out of scope? -- Posted via http://www.ruby-forum.com/.

Hi, I think I''m doing this the right way, but can''t get it going. I''m building a menu from the values in a mySQL table, and want to build it on the fly. This is something that should be working but only works halfway: <% @pages = Page.find(:all, :conditions => [''site_id = 4'']) %> <% @pages.each do |p| %> xyz <%p.id%> <%

Hi, I have a problem where I need an auto-incremented id back from the database for a statement that has yet to be committed. The operation that uses the id may fail, and if so, I need to rollback the database. I can''t figure out how to send only the statement to the database without the commit without sending over hard coded SQL. This is what I started out with: 1 def add_album

Hi, I''m searching for a method of eager loading polymorphic associations under activerecord 2.0.2.
