First thing first: Don't forget to setup the environments in my case for example: config/environments/development.rb [ruby] # mailer defaults config.action_mailer.default_url_options = { :host => "localhost:3000" } [/ruby] config/environments/production.rb [ruby] config.action_mailer.default_url_options = { :host => 'elh.mx' } [/ruby] And now let's add the helpers If you are just using the Rails you can do something like: [ruby] module MailersHelper def host_url_for(url_path) root_url.chop + url_path end end [/ruby]

Hello Guys, In this post I'm going to start putting all about queries in rails, so if you find any interesting query let me know and I can put it here, so let's get right to it: Something that I found really useful to understand how the joins works is using this image: If you want to retrieve all the orders that contain more than 2 shipments (Using Spree models) [rails] # this is using inner joins buy default from rails Spree::Order.joins(:shipments).group("spree_shipments.order_id").having("count(spree_shipments.id) > 2") [/rails]

frontend, javascript / 24.02.2015

After thinking a little bit I don't remember writing too much about javascript and I really like javascript !!!, well here it is the first post that I want you to share with you guys. Sometimes you need to get the absolute url from javascript for those cases you can find useful the following function: [javascript] window.Utils = { httpUrlFor: function(url_params) { var domain, port; domain = "http://" + window.location.hostname; port = window.location.port ? ":" + window.location.port : ""; return domain + port + url_params; } }; # or in coffee-script window.Utils = httpUrlFor: (url_params) -> domain = "http://#{window.location.hostname}" port = if window.location.port then ":#{window.location.port}" else "" "#{domain}#{port}#{url_params}" [/javascript]

Sometimes when you're playing with new code it is kind of difficult to find out where they are declared or maybe this method are declared using metaprogramming and they are not explicitly declared: In most of the cases you can just copy your method or function and search it in the repository using ack http://beyondgrep.com/ or silver searcher(ag) https://github.com/ggreer/the_silver_searcher but if you are not able to find the method you're looking for using some of this searcher tools you can use some gem for debugging for example debugger https://github.com/cldwalker/debugger or pry https://github.com/pry/pry.
