jasonkarns / find_redundant.rb
Created February 3, 2012 03:01
# This script greps the code base for all associations with an explicit foreign_key.
# For each defined association, it attempts to infer the foreign_key using our inflection rules.
# If the inferred foreign_key matches the explicit foreign_key, then the foreign_key declaration can be removed.
# If not, then there is the potential that the inflection can be added to config/initializers/inflections
# (unless it is an exception to an already-defined initializer inflection)
# USAGE: run from the command line
# $ ruby find_redundant_foreign_keys.rb

jasonkarns / fb.js
Last active December 16, 2015 19:59
Facebook's JS SDK doesn't support registering multiple 'ready' handlers. So here's an implementation inspired by Twitter's SDK. (uses underscore)
window.fb = (b = { _e: [], ready: function(f){ b._e.push(f); } });
window.fbAsyncInit = function() {
fb.ready = function(f){ f(); };
_.invoke(fb._e, 'call');
};
fb.ready(function(){ console.info("facebook sdk loaded"); });

jasonkarns / partialObject.underscore.js
Last active December 16, 2015 22:09
Instead of partially applying parameters to a function, partially apply properties on a plain old javascript object.
_.partialObject = function(func, partial_object) {
return function(object) {
return func.call(this, _.extend({}, partial_object, object));
};
};
