I have a real-world application with some complex queries that I want to convert to Arel (as part of an upgrade to Rails 3.1). So that I can understand what I''m doing before I flail around in my real app, I wrote a little sample app (just the models) with some similar associations -- one table joined with itself and more tables that join to another table, so there are some queries that

I''m building an app that needs i18n support across the entire database (i.e. localized attributes). In order to do this I''ve created a special HABTM join table that can be associated with _any_ other table: create table language_strings ( for_table varchar(255) not null, foreign_id int not null, language_id varchar(5) not null, attr_name varchar(255) not null, value text

I''m attempting to use the example given in the Rails Recipes book chapter 2, to create a select drop-down using the InPlaceEditor function (modified to be InPlaceSelectEditor.

Hi, I''m wondering how I should go about making my website multi-lingual. Basically, there will be different content for the different languages, and that''s not really a problem... all I need to do is give each content entry in the database a language_id.

DB field names: If I have a table that references 2 or more separate users from my users table, is there a recommended naming convention for this situation? In my case, I have 3 users associated with a record in my projects table: requester_user_id created_by updated_by I could name one of them "user_id", and then projects.user would work I guess, but wouldn''t work

My envrionment is Rails 1.1.2, Ruby 1.8.4, MySQL 5.0.21 on WinXP. When I run ''rake migrate'' after pulling the lastest 1.1 branch of Globalize plugin, I get the following error message: (in C:/Rails/Application/medicalmind) == GlobalizeMigration: migrating ============================================== -- create_table(:globalize_countries, {:force=>true}) -> 0.2110s

I''m trying to implement internationalization in my app. I followed the instructions on the Globalize example (http://wiki.globalize- rails.org/globalize/show/Example+Application), using in_place_editor. The translation works fine, however, I can''t get in_place_editor to work to translate the strings. My controller: class Admin::TranslateController < ApplicationController
