In the seemlingly endless search for the actual correct and easy way to deploy a Rails app, we have tried several ways. We tried out using Apache2 and running a cluster of Thin servers. With the built in threading of Puma we decided to use it with Nginx.
# This example does an AJAX lookup and is in CoffeeScript
$('.typeahead').typeahead(
# source can be a function
source: (typeahead, query) ->
# this function receives the typeahead object and the query string
| <script> | |
| // Charles Lawrence - Feb 16, 2012. Free to use and modify. Please attribute back to @geuis if you find this useful | |
| // Twitter Bootstrap Typeahead doesn't support remote data querying. This is an expected feature in the future. In the meantime, others have submitted patches to the core bootstrap component that allow it. | |
| // The following will allow remote autocompletes *without* modifying any officially released core code. | |
| // If others find ways to improve this, please share. | |
| var autocomplete = $('#searchinput').typeahead() | |
| .on('keyup', function(ev){ | |
| ev.stopPropagation(); |
| class User < ActiveRecord::Base | |
| alias :devise_valid_password? :valid_password? | |
| def valid_password?(password) | |
| begin | |
| devise_valid_password?(password) | |
| rescue BCrypt::Errors::InvalidHash | |
| return false unless Digest::SHA1.hexdigest(password) == encrypted_password | |
| logger.info "User #{email} is using the old password hashing method, updating attribute." | |
| self.password = password |
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.
| fs = require 'fs' | |
| path = require 'path' | |
| util = require 'util' | |
| express = require 'express' | |
| app = module.exports = express.createServer() | |
| app.get '/', (req, res, next) -> | |
| music_path = path.join __dirname, 'music' | |
| fs.readdir music_path, (error, files) -> | |
| output = [] |
