//If you are using express router

var route, routes = [];

app._router.stack.forEach(function(middleware){

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

require 'fileutils'

start_time = Time.now


SOURCE_DB = {
  :name => 'db_name',
  :user => 'db_user',
  :password => 'db_pass',
  :host => 'localhost'

iMagesh

For new user
adduser user_name 

add sudo permission to the user
adduser user_name sudo

For generate key(local)
ssh-keygen -b 4096

copy key to server (ubuntu)

To enable the precompilation of all non.js/.css assets within vendor/assets just add this to config/initializers/assets.rb:

Rails.application.config.assets.precompile << Proc.new { |path, fn| fn =~ /vendor\/assets/ && !%w(.js .css).include?(File.extname(path)) }

Be aware that this will precompile ALL non .js/.css assets that you have there, some plugins or libraries might have .txt or other files around, and those would end up into your precompiled list also.

If you need to precompile images only, you could use this:

Rails.application.config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)
