jwietelmann / every_controller_spec.rb
Created January 12, 2016 17:37
An RSpec sanity check to run against every Rails controller.
# What the heck is this spec about?
#
# It's a gut-check that runs against every controller in the application.
# It is NOT a replacement for writing controller specs for each controller.
#
# What this does is things like check to make sure you didn't forget to lock
# down the index action of a controller to authorized users, checks to see if
# common routes are throwing silly errors, etc.
#
# Your controller passing these tests does not guarantee that it is healthy.

Getting Good at Vim

I have used Vim to write code for about a year, and I can confidently say that Vim does two things for me well. The most obvious thing is that it cuts down on my text editing time. If you consider the amount of time you spend highlighting with the mouse and then returning back to the keyboard to edit text, daily, over the course of a year that time begins to adds up.

jwietelmann / mongoose-single-subdoc.js
Created November 30, 2012 04:18
Hack to fake single subdoc field in a mongoose schema
// mongoose doesn't like single embedded schemas
// it likes them as arrays of an embedded schema
// so this is a cheater hack to fake a single subdoc
// it creates a field named `_yourField` and a virtual named `yourField`
// and it makes sure the array keeps just one element in it
// USAGE EXAMPLE:
/*
var models = require('models')
, ChildSchema = models.ChildSchema
, singleSubdoc = require('mongoose-single-subdoc');
