How to use absolute urls and helpers from mailers with Rails Or Spree

21 Apr How to use absolute urls and helpers from mailers with Rails Or Spree

First thing first: Don’t forget to setup the environments in my case for example:
config/environments/development.rb

# mailer defaults
config.action_mailer.default_url_options = { :host => "localhost:3000" }

config/environments/production.rb

config.action_mailer.default_url_options = { :host => 'elh.mx' }

And now let’s add the helpers

If you are just using the Rails you can do something like:

module MailersHelper
  def host_url_for(url_path)
    root_url.chop + url_path
  end
end

and require the helper in your mailer:

class Mailer < ActionMailer::Base
  default from: "no-reply@lhola.com"

  helper :mailers

  def my_method
    @myId = 'id'
  end
end

mailers/my_method.html.erb:

<%- edit_path = your_route_path(@myId) %>
<%= link_to 'Anchor text', host_url_for(edit_path) %>

If you’re using Spree you can do it like so:

module MailersHelper
  def spree_host_url_for(url_path)
    spree.root_url.chop + url_path
  end
end

and require the helper in your mailer:

class Mailer < ActionMailer::Base
  default from: "no-reply@lhola.com"

  helper :mailers

  def my_method
    @myOrderNumber = 'R23234234'
  end
end

mailers/my_method.html.erb:

<%- edit_order_path = spree.edit_admin_order_path(@myOrderNumber) %>
<%= link_to "#{@myOrderNumber}",
            spree_host_url_for(edit_order_path) %>
