Rails Models

Generating models

Associations

belongs_to

has_one

Template Components

Used to provide structural templates.

Pattern

t-template-name

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.

	class UsersController < ApplicationController

	respond_to :html, :json

	def index
	@json = User.all.to_gmaps4rails
	respond_with @json
	end

	end

	var cat = {};

	/**
	* cat.NewsBox
	* Retrieves news from Google
	*/
	cat.NewsBox = (function(){

	function NewsBox(searchTerm, injectFn) {
	this.searchTerm = searchTerm;

	<!DOCTYPE html>
	<script src="url.js"></script>
	<script>

	var url = new URL('http://www.example.com/a/b/c.html?p=q&r=s&p&p=t#hash');

	for (var key in url) {
	console.log(key, url[key]);
	}

	You can now create a spinner using any of the variants below:

	$("#el").spin(); // Produces default Spinner using the text color of #el.
	$("#el").spin("small"); // Produces a 'small' Spinner using the text color of #el.
	$("#el").spin("large", "white"); // Produces a 'large' Spinner in white (or any valid CSS color).
	$("#el").spin({ ... }); // Produces a Spinner using your custom settings.

	$("#el").spin(false); // Kills the spinner.

	var pubsub = {};
	(function(q) {
	var topics = {}, subUid = -1;
	q.subscribe = function(topic, func) {
	if (!topics[topic]) {
	topics[topic] = [];
	}
	var token = (++subUid).toString();
	topics[topic].push({
	token: token,
