How to create associations with Factory Girl?

I watched the RailsCasts episode on factory_girl, and I'm trying to get out of fixtures.

* Does anybody know an open source project that uses many of the factory_girls features?

I came up with a pseudo code for possibly showing some association features I don't understand yet.

Here's the code. It's blog posts with comments plus tagging: ############################ CODE STARTS create_table "posts", :force => true do |t| t.string "title" t.text "content" end

create_table "comments", :force => true do |t| t.ingeter "post_id" t.string "content" end create_table "tagging", :force => true do |t| t.integer "tag_id" t.integer "post_id" end

create_table "tags", :force => true do |t| t.string "name" end
