I'm guessing all objects that are local to the action are passed into the view? I never see sample code that actually specifies which objects are passed to the view! Is it good practice to create a 'model' object and then assign, as properties to the 'model' object, all objects you want to pass to the view? How can you explicitly pass...

I just created a new gem (using bundler) and want to add Active Record support. So I added s.add_dependency "activerecord", "~> 3.0" to my gemspec. Then I use Bundler.setup and Bundler.require and thought that I have access to Active Record now, but I haven't. I have to explicitly use require "active_record". Any idea why Bunder.require ...

But I'm not as certain of what to do with: ENV["RAILS_ENV"] ||= 'production' We've got it at the top of a whole bunch of rake tasks and daemons... and the id...

I'm trying to deploy a rails app to Heroku and I'm running into some basic git problems. I'm new to this all -- rails, git, heroku -- so I'm afraid I'm getting lost on what's probably a fairly basic concept. I've pushed the app to Heroku, but when I'm migrating the db ($ heroku rake db:migrate), I keep getting the following error: rake...

For example, class User < AciveRecord::Base has_many :events, :finder_sql => 'SELECT something complex' end While user.events returns what I need, the number of records returned can be huge, so I need to have a way to pass parameters for LIMIT. Is t...
