basic support for PostgreSQL Enums in ActiveRecord - to be placed in an initializer
##
# This provides `create_enum` and `drop_enum` methods for migrations, which creates
# a Postgres ENUM type with the provided values.
#
# It'll also dump these into the schema.rb to be loaded into another DB (e.g. rake db:test:load)
#
# In order to reference the new enums as actual types, ActiveRecord needs to know about them, so
# make sure they are all represented in the `types` array below
#
# Then you can reference them in your migrations, e.g.

The way I had to add a github repo webhook for pull requests

This is more complex than necessary.

GitHub webhooks for a URL by default only fire on repo pushes. There appears to be no way in the web UI to set up webhooks for other events. And so we go to the API. I prefer to do this type of thing with Hurl.

Friendly URLs in Rails

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

# config.ru for Pow + Wordpress, based on http://stuff-things.net/2011/05/16/legacy-development-with-pow/
# added hackery to work around wordpress issues - Patrick Anderson (patrick@trinity-ai.com)
# added rubygems, replaced script_path with script from path_parts, added to_return to fix return error - Paul Cook
# clearly this could be cleaner, but it does work
require 'rubygems'
require 'rack'
