I'm doing a first pass at rolling my own authentication and sessions in rails and am not sure that I understand the session support that is present. (By first pass, I mean I'm initially authenticating via http, not https. Production code will use https.) My understanding of secure sessions is that you pass a token to the browser via a c...
I have a View that can vary significantly, depending on the 'mode' a particular user has chosen. I thought I would extract the different behavior into two different Helpers, and then have code like this in the Controller: class MyController < ApplicationController case mode when 'mode1' helper "mode1" when 'mode2' helper "mode2" e...
Hi everyone, I know that Hpricot is still a standard but I remember hearing about a faster more expressive HTML parser for Ruby. Does anybody know what it's called and if it is worth switching to from Hpricot?? Thanks in advance ...
I have a Rails site, where the content is written in markdown. I wish to display a snippet of each, with a "Read more.." link. How do I go about this? Simple truncating the raw text will not work, for example.. >> "This is an [example](http://example.com)"[0..25] => "This is an [example](http:" Ideally I want to allow the author to (...

Let's say we have two classes, Foo and Foo Sub, each in a different file, foo.rb and foo_sub.rb respectively. foo.rb: require "foo_sub" class Foo def foo FooSub.SOME_CONSTANT end end foo_sub.rb: require "foo" class FooSub < Foo SOME_CONSTANT = 1 end This isn't going to work due to the circular dependency - we c...
When I reading source code of Beast, I found a lot of code like this: <%= 'Password'[:password_title] %> It seems like a call to [] method with Symbol as input parameter to a String to me, but I didn't find such type of parameter of String [] method in the ruby API. What is this means? thanks in advance. ...

I'm writing some functional tests for a controller in rails, using mocha to do mocking/stubbing. Is there a way to prevent the template from being rendered during the test, so that I can test only the code in the controller? It looks like rspec provides something like this, but I'm not using rspec. ...
After making a few modifications to a rails app I am tinkering on, railroad stopped working. The verbose output gives some clues. I wonder if other folks have encountered this and if there are some pointers for fixing this problem. Is it a data modeling error? Is it a problem with railroad? Error log follows... railroad -vM Loading appl...
I have a collection of movies and TV shows in iTunes, and I'd like to rename them to an XBMC compatible naming convention without breaking the links in iTunes. All the necessary metadata (season number, show name, episode number, etc) seems to be in an XML file that iTunes manages, and the episode name is the current file name. So progr...

I have some settings I need in a Javascript file -- servers to connect to -- that changes based on my environment. For development, test, and staging, I want to use the staging servers; for production, the production servers. I already have the settings in Ruby (configured in my environment/xyz.rb files). So far, I've been dynamically...
Dear Stack, Is it possible, using an Observer, to observe the creation of JOIN records? For example, you have a User Model that has_and_belongs_to_many Book Models. Is it possible to monitor books_users records as they are created or deleted or must I have a BookUser model to do this? Example of what I want to observe: User.books <<...
I want to write tests for my app, though each time I look at rspec.info, I really don't see a definite path to take towards "doing things right" and testing first. I watched the peepcode videos on rspec more than once, yet it doesn't take. I want to take more pride in my work, and I think that testing will help. How can I break throug...

I'm writing a rake task that does some DB work outside of Rails/ActiveRecord. Is there a way to get the DB connection info (host, username, password, DB name) for the current environment as defined in database.yml? I'd like to get it so I can use it to connect like this... con = Mysql.real_connect("host", "user", "pw", "current_db") ...
I have some rails models which don't need any persistence, however I'd like rails to think the model actually has attributes x, y, z so when calling methods like to_json in the controller I get them included for free. For example, class ModelWithoutTableColumns << ActiveRecord::Base def x return "Custom stuff here" end There is n...
I am trying to create a form in Rails 2.2.2 that populates a field based on a choice a user has made in an 'auto_complete' field. It looks as though the observe_field functionality is what I need to use but I'm stuck on how to update the value of an existing text field. The sequence of events I am trying to model is follows: 1) Use typ...
Most dead-tree books and web tutorials address Rails 1.X. I'm wondering if they are worth using to learn Rails 2.X. If so, what sections and concepts should should I avoid and what have pretty much stayed the same? ...
