sharing-a-devise-user-session-across-subdomains

two key words, sample cookie_store key and secret_key_base devise_secret_key

Rails.application.config.session_store :cookie_store, key: "vcooline_ikcrm#{Rails.env}_#{SESSION_DOMAIN.try(:underscore)}_session", :domain => :all, :expire_after => 86400*90, :tld_length => 2

You might get weird things like halfway Devise sessions sharing, but only allowing you to create and destroy the session on the root domain. Using :all works great if you’re using localhost, but when I started using lvh.me:3000 for testing I had those problems (lvh.me stands for local vhost me and is a domain that simply points to localhost which makes for zero-config subdomain development. It’s super handy.).

get 'crm_base_agent/', to: "crm_base_agent#index"

Usage

jhjguxin

Array.prototype.each_slice = function (size, callback){
  for (var i = 0, l = this.length; i < l; i += size){
    callback.call(this, this.slice(i, i + size));
  }
};

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10].each_slice(3, function (slice){
  console.log(slice);
});

// Add an URL parser to JQuery that returns an object
// This function is meant to be used with an URL like the window.location
// Use: $.parseParams('http://mysite.com/?var=string') or $.parseParams() to parse the window.location
// Simple variable:  ?var=abc                        returns {var: "abc"}
// Simple object:    ?var.length=2&var.scope=123     returns {var: {length: "2", scope: "123"}}
// Simple array:     ?var[]=0&var[]=9                returns {var: ["0", "9"]}
// Array with index: ?var[0]=0&var[1]=9              returns {var: ["0", "9"]}
// Nested objects:   ?my.var.is.here=5               returns {my: {var: {is: {here: "5"}}}}
// All together:     ?var=a&my.var[]=b&my.cookie=no  returns {var: "a", my: {var: ["b"], cookie: "no"}}
// You just cant have an object in an array, ?var[1].test=abc DOES NOT WORK
