My Git Deploy Workflow

I use this for static and simple [Sinatra][1] based sites -- great for prototyping simple apps. Credit goes to http://toroid.org/ams/git-website-howto for the original idea.

If you don't know what this is, here's an example of how I deploy my website/app to a server:

# create/update/delete files in my site
git add .
git commit -m "description of the changes I made"

git push

  Capybara.save_page body, "#{path}.html"
  page.driver.render Rails.root.join "#{Capybara.save_and_open_page_path}" "#{path}.png"
end

Polymorphic Associations reversed

It's pretty easy to do polymorphic associations in Rails: A Picture can belong to either a BlogPost or an Article. But what if you need the relationship the other way around? A Picture, a Text and a Video can belong to an Article, and that article can find all media by calling @article.media

This example shows how to create an ArticleElement join model that handles the polymorphic relationship. To add fields that are common to all polymorphic models, add fields to the join model.
