I'm trying to get tags working in my rails application and want to use acts_as_taggable. Firstly I followed the instructions I found in Rails Recipies (a free sample bit online) that used the acts_as_taggable plugin.

The Background I started a Rails project recently and decided to use RESTful controllers. I created controllers for my key entities (such as Country) and added index, new, edit, create, show, update, delete. I added my map.resources :country to my routes file and life was good. After development progressed a little, I started to encoun...
I'm using Mongrel::DirHandler to control response headers for static files - this works great on my dev machine. My production machine uses Passenger so my headers aren't getting set. How do I control headers for static files when using Passenger? snippet from my environment.rb: if defined? Mongrel::DirHandler module Mongrel clas...

I am using Apache + Mongrel, I cannot use Passenger because I am working on Windows (please forgive me for this deadly sin!) Which of the following is a better approach?

I have two machines... a development machine and a production machine. When I first brought my rails app onto the production server, I had no problem. I simply imported schema.rb by running rake db:schema:load RAILS_ENV=production. All was well. So, then on my development machine, I made some more changes and another migration, and t...
I have a rails app that has picked up a bit of traction, but I have a serious headache to deal with. It's a basic sort of asset manager application - users upload their photos, .pdfs, videos, etc., and the system allows them to manage how that asset is presented. I started with a fairly standard rails view - just what gets generated by...

There is an assets table that has key :string (file name) and data :binary (file contents). I'm using the rubyzip library, and have made it as far as this: Zip::ZipFile.open(@f...
It's possible to write Markdown content with invalid syntax. Invalid means that the BlueCloth library fails to parse the content and throws an exception. The markdown helper in Rails doesn't catch any BlueCloth exceptions and because of that the complete page fails to render (500 Server Error page is rendered instead). In my case, users...
