similar to: Retrieving Mutliple Records using find_by_*

In the Agile RoR book, page 219 (softcover version) they talk about the fact you can use the methods: find_by_ and find_all_by_ and fill in the last piece with a valid column name. So I have a database table called "parts" and the following columns: id partname partnumber vendor I do the following: (connection to DB already established) class Part < ActiveRecord::Base end

I just created the sass directory in my stylesheets directory and when I reload my page I get this error: Status: 500 Internal Server Error Permission denied - /Users/Justin/kicksite/trunk/public/ stylesheets/ application.css /usr/local/lib/ruby/gems/1.8/gems/haml-2.0.0/lib/sass/plugin.rb: 72:in `initialize'' /usr/local/lib/ruby/gems/1.8/gems/haml-2.0.0/lib/sass/plugin.rb: 72:in

When I use find_by_name method I get LIMIT 1 result. > SELECT "users".* FROM "users" WHERE "users"."age" = 25 LIMIT 1 But the "age" column is not unique in my table and its value may repeat. So I expect that an array of records where "age" is 25 will be returned. But AR limits the query by 1. How to avoid it? Or is it the default

In my app, a user logs in [via the login generator] and has access to details of his account, and transactions attached to his account. This is achieved in the standard rail manner by passing the account id or transaction id between the controller and the view. But what is to stop someone hacking the URL or view html to access another account id or transaction id ? eg /account/show/46 becomes

Hi, A project came up that has made me realize that it''s time to learn RoR. I''ve got everything up and running (Ruby 1.8.6, Rails 2.1, MySQL 5, Webrick) and am using Aptana with RadRails for development. I''ve installed the "recipes" demo application and have been poking around for the past couple of hours, and now I have a few questions about how things work:

Hello everyone, I have a rails app which uses email as login name. At some point, I have to search the user, in the User model by email. For some reason, the method User.find_by_email(email) returns nil, even though the user is in the database. The same applies for any find_by_* method that searches by any database column. I was able to find the user using the User.find Does anyone have an idea

Hello there, I''m wondering how do they create functions on the fly? find_by_any_column_name ??

Hi I'm hoping someone can help me I am a relative newbie to R. I have data that is in a similar format to this... Experiment Score1 Score2 X -0.85 -0.02 X -1.21 -0.02 X 1.05 0.09 Y -1.12 -0.07 Y -0.27 -0.07 Y -0.93 -0.08 Z 1.1 -0.03 Z 2.4 0.09 Z -1.0 0.09 Now I can easily have a look at the overall correlation of score 1 and 2 by doing this plot(data[,2], data[,3]) or fit <-

I have a theory on the cause of a problem but it is still only a theory. I wonder if anyone here can confirm. I have a multi-isp configuration with a multi-path default route to each ISP, equally weighted. I am seeing, periodically, traffic dropped due to martian detection and errors logged on inbound traffic, but at other times, that same exact traffic will be allowed, no errors. My

Hello. I am trying to make use of rsync for backup purposes. I want to use it with the -b switch: it renames older FILE to FILE~ instead of replacing it with the newer version. This way, only the newest and the second most recent versions of a file are saved. I want to have more versions. One approach to this can be inpired by --backup-dir operation. I'd rather extend the backup

New to Asterisk's and loving it so far. Does anyone know of any functionality in Asterisk's (or more so phones) that allows line numbers to be lit up like a switch board on a phone? So that someone can page another person with 'call on line 3'. I'm not really a telco guy and are still learning terminology for things. Any idea's? -- Regards, JB Hewitt Business:

Hi, I want to use four independent variables to predict the output of one dependent variable using a linear model lm. I want to compare all possible combinations of the 4 independent variables, including singles, pairs and triples. I was thinking of using the AIC test to compare all models and pick the best one. The model looks like this : lm(Y ~ X1 + X2 + X3 + X4) Thanks for your help

Along the same lines as the default javascript library discussion [1], why don''t we switch the default test library to RSpec? The stats [2] posted by Xaviar in the other thread seem to support that RSpec is the preferred way to test.

Calling All Mongrel Minions! I wanna have some fun and would like this as a Christmas present. The site http://www.workingwithrails.com/ has this lame popularity system that''s kind of irking some of the main Ruby contributors.

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

Hello everyone, While walking through AWDWR, Task D: Add a Dash of AJAX, I was initially unable to let the AJAX magic work. Hitting the Add to Cart button doesn''t yield to any output on its own; I had to manually refresh the pages to witness the change. But when I tried to restart the ruby server, and load the application again, everything worked fine. Any explanations to behavior
