similar to: select some columns only when doing "find"

I have 3 tables keywords (keywords attached to a file) files (info about the file) paths (path for the file) [This is a legacy database, so I can''t change this] keyword belongs_to file and file belongs_to path. Users need to be able to search the keywords, but they only have access to certain volumes, so the results need to be limited by the path. I also need to show paging,

I''ve been trying to use Rails on a database where the biggest datawarehouse-style table doesn''t have a primary key. It really doesn''t make sense and just adds extra unnecessary space. I do have, however, a column that I normally use to search on (IP) that returns many rows. The table also references several other tables through rails-friendly foreign keys. Simple AR

Sorry if this is a simple question, I''m a CSS noob. I have a rails app that is displaying posts, I am having it generate each post with its own div like "post_19", "post_20", etc. I could make it so it puts another div around that div (i need the individual post div''s for deletion with AJAX) but would rather not. Is there some way to use CSS to do

Hi all, I''m working actually on a Control Panel to manage a mail system. Until now, when I create a new mail account, i do an insert and protect the pasword with ENCRYPT(''password'') function. I can''t change the method to SHA1 or MD5 because the SMTPd a IMAPd will not support it. Can you explain me how to force RoR to rewrite the INSERT SQL query and use

Hi I am trying to use active record to copy some data. One of the entry I am copying is type interval (Postgres); however, it lose some precision after I copied that column. Here is what I did: @newData.elapsedtime = @oldData.elapsedtime @newData.save Result: both displayed as 00:00:02.453 in the table, however, if I use the following command to convert its value into float ( SELECT

I have a model with a datetime field called start_date. I''d like to do a find on the model so that it returns only records with the start_date equal to the current day. Something like this: @foos = Foo.find(:all, :conditions => //?? start_date equal to today''s date ??// ] ) Thanks in advance for any help. -------------- next part

I want to show a users entries based on there login id. I have tried this: View: <div id="myfish"> <%= render :partial => ''myfish'', :locals => {:user => session [:user].id } %> </div> Partial: <% for entry in @entries %> <table border ="0" CELLSPACING="0"> <tr class="<%= alternate

sorry again, i''m building a registration form, getting stumped on the country listbox. any ideas how i could build a listbox for countries, taking it''s content from a data table? i''d imagine i''d have to generate a data model for country, fill it in with all the current ISO spec countries; that i can do. then tie that data model to the account controller.

Hopefully the subject line didn''t scare you. That said... I have a simple polymorphic relationship (is that possible?): class Part has_many :attachments, :as => :attachable end class Attachment belongs_to :attachable, :polymorphic => true end Calling Part.find(:first).attachments yields this SQL error: ActiveRecord::StatementInvalid: Mysql::Error: Unknown column

I need to show a different background color depending on the type of comment posted. The type of comment is determined from a drop-down selection. I figured the simplest way would be to do something like I have below, but I can''t seem to get it to work: <tr <%= puts ''"style = "background: red;"'' if comment.comment_type == ''Hiring

Hi I am trying to get RoR to work with Postgresql 8,2.5 (latest stable version) Steps taken 1. Download Postgresql 1.82 and installed successfully 2. Edited my Database.yml development: adapter: postgresql database: test_development username: postgres password: xxx host: localhost test: adapter: postgresql database: test_test username: postgres password: xxx host: localhost

When I run "rake" using a postgres 8.1 database, I get a bunch of these notices. NOTICE: CREATE TABLE will create implicit sequence "categories_id_seq" for serial column "categories.id" NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "categories_pkey" for table "categories" How can I avoid those? I take it I need to modify the

In Postgres, I use different database schemas for each application, by declaring, e.g.: class ApplicationController < ActionController::Base ActiveRecord::Base.table_name_prefix = "keywords." end I assumed that the sequence names were also prefixed with the database schema names, e.g. keywords.things_id_seq But Rails 1.2.3 assumes the sequence is *NOT* in the same schema as the

Is there something like MAMP, but uses PostgreSQL instead? I found a couple PostgreSQL dmg''s, but one was < 8.x. For those who use PostgreSQL on Mac, how''d you install it (fink, package, please don''t say compile!)? Thanks, Joe -- Posted via http://www.ruby-forum.com/.

I know how to avoid SQL injection attacks when you use :conditions User.find :first, :conditions => ["login=?", params[:username]] but how about with :order, :limit or :group? # uh-oh...spaghetti-oh User.find :first, :order => "login; delete from users; select * from users" Pat --~--~---------~--~----~------------~-------~--~----~ You received this message because you

Sorry for all the questions today... Beyond the obvious things--models, controllers, helpers, and other framework-related types--where should I put the code for my own types? For example, I was thinking of writing my own AJAX-friendly paginator, but I don''t know where to put the code for that sort of thing. I would prefer to keep things object-oriented, so I would rather do a lot of

I am a Rails noob, working on bringing a legacy db system into the 21st century. I want to localize the UI for two languages (EN/JA). Since I am already using the salted user system, I have been playing around with T. Fuchs'' localization module. Nice and simple, already up and working. But here''s the problem: Japanese text is wrapping weirdly in table cells. I could set

Hi guys, I need your help. Here is my database.yml: development: adapter: postgresql database: db username: username password: mypassword # Connect on a TCP socket. Omitted by default since the client uses a # domain socket that doesn''t need configuration.

Hello, I have tried to install the salted hash login generator by following the quick start guide at: http://wiki.rubyonrails.com/rails/pages/SaltedLoginGeneratorQuickstart. Everything seems to work fine until I try to run the unit tests by doing ''rake test_units'', then I get the following error message: <error-message> [brasse@keso login-test]$ rake test_units (in

I am curious what you find is good and bad MVC design. Let''s use the find and find_by_sql methods as examples. Currently I have these spread out all over the place... View: here I have some find methods when I am for example populating a select list with choices in a form. Controller: here I have the simpler find methods. Model: here I have the more complicated find methods (usually
