Our application is developed using Rails 2.3.5 along with ActiveScaffold. ActiveScaffold adds quite a bit of magic at run time just by declaring as following in a controller: class SomeController < ApplicationController active_scaffold :model end Just by adding that one line in the controller, all the restful actions and their corres...

How does one "parameterize" variable input into a Regex in Ruby? For example, I'm doing the following: q = params[:q] all_values.collect { | col | [col.name] if col.name =~ /(\W|^)#{q}/i }.compact Since it (#{q}) is a variable from an untrusted source (the query string), I have to assume it could be an attack vector. Any best practice...

Hi, I'm trying to create a drop down menu to allow a user to change an entry's field in my table. The user has one of three options -- hot, medium and cold. I already have text_fields that do essentially the same thing for other fields, that all update when the user clicks on a submit_tag. Is there an easy way to implement a drop-do...

I have Labellings which belong to Emails and Labels. Each labelling must be unique to the email/label pair - so an email can only be labelled 'test' once. I'm doing this with validates_uniqueness_of :label_id, :scope => :email_id. This works as expected. When I am labelling emails, I want to add the labelling if it is unique, and do n...

From what I understand, Google ignores sreg attribute requests, and only listens to the AX schema for email address. Here's my code: def open_i...
