Following the guide at http://github.com/fortuity/rails3-mongoid-devise I've managed to setup Rails3 with Haml, Devise, and Mongoid. (As a side-note, the guide is really detailed; recommended reading for new Rails users!) Only problem is I can't get Rails to render my Haml views: Started GET "/" for 127.0.0.1 at 2010-07-01 14:40:23 +02...

I have a template that generates a rails app. The problem is that in my template scenario I substitute some files, like environment.rb, that need to know rails app name to run things like AppName::Application.initialize!. I could get the app name from the command line arguments, but that's not always possible, since a user could do that:...

In the controller I could create a task with: @task = Task.new(params[:task]) under 1.9 I have to do @task = Task.new(params[:task]) @task.due_at = params[:task][:due_at] Is there something about mass assignment I'm missing? Thanks! c...
I am porting a 2.x rails app to rails3; we'll call it foo-app. Foo-app is one section of a larger rails app and lives at main_rails_app.com/foo-app. Previously we just set up the following in our foo-app production config to ensure that our foo-app routes worked properly: ActionController::Base.relative_url_root = "/foo-app" However, ...
