I have a Rails 3 application with a User class, and a tab-delimited file of users that I want to import. How do I get access to the Active Record model outside the rails console, so that I can write a script to do require "???active-record???"

I'm looking to build an application that handles authentication and authorization for a variety of smaller apps that may or may not be rails applications (e.g. some with sinatra, some with non-ruby frameworks, etc). These applications will be on separate domains. Can I do this with Authlogic? I do not want to setup a rails application f...
OAuth Provider Service and Rails 3
I am trying to look into setting up an OAuth Provider Server with Rails 3 but can't seem to find anything out there to accomplish this. I am also a newb when it comes to oauth, so excuse my ignorance. When setting up an oauth server do I need to already have an oauth account at somewhere like agree2.com? Or can I just use my own serve...
Ruby on Rails: Update page multiple times in controller
So I have a rather long controller function that performs various tasks, and it takes around 10-15 seconds. I want to be able to update the user on the status of the function as it goes along (progress bar). Ideally, the function is called as an Ajax request, and would then update the page as it goes along. This would work except you can...
How do I get my application.js (jQuery) file to execute a script from somewhere else in my Rails app?
I'm starting to feel crazy because what I want to do is so simple: write a line of javascript in my Rails application.js file that will cause a script somewhere else in the app to execute. I've tried it with jQuery.get() and jQuery.getScript() but nothing seems to work. Here's some sample code from my application.js file: #application....

Rails, saving the foreign key in a `belongs_to` association.
I think I'm having a really basic problem here but I can't seem to put my finger on what I'm doing wrong. So the issue here is when I save an instance of a model the foreign_key for the models's belongs_to association (in this case the user_id is not being saved, so I'm forced to do this: def new @thing = Thing.new(:user_id => curre...
Rails: Images on one server, CSS and Javascript on another
Hi, I am working on a rails app that has a bunch (hundreds) of images that are hosted on an S3 server. To have helpers like image_tag point here I had to add this to by config/environments/development.rb test.rb and production.rb: config.action_controller.asset_host = "http://mybucket.s3.amazonaws.com" However, this also means that it...
Ruby on Rails: How are people making search forms on sites with the broken textfield parsing that removes quotation marks?
I'm using Sunspot Solr search, which works fine for the most part for basic search. It's supposed to be able to handle quotation marks around phrases, so that a search for test case will return documents with both test and case, whereas a search for "test case" should return documents with the phrase test case. However, I've been pullin...
Rails new GEM_HOME
I recently upgraded to Ruby 1.8.7 (had an issue with 1.9.2) and had to reinstall RubyGems. Now my project can't see any of the old gems in my GEM_HOME, is there a way to point my new gem binary to my previous GEM_HOME? I can't find anything online and it's a big pain to install them all again one by one. I'm also on a Mac, so it's at:...
Ruby on rails: Devise, want to add invite code?
Hi, I would like to add an invite_code requirement for users to sign up. Ie. in addition to requiring them to specify an email/password combo, I want an additional field :invite_code.

Disabling ActiveModel callbacks
I published an article on disabling ActiveModel callbacks, but I’m not completely sure this is the prettiest way to do something like this. Mongoid::Timestamps adds a before save callback that updates the updated_at field. Let's say I don't want that in some cases and I disable the callback like this: class User # I'm using Mongoid, ...
