Shippinglogic¶ ↑

Please note, this library is no longer supported and is being deprecated. A replacement is being worked on that will allow for a seamless transition should use choose to do so.¶ ↑

The goal of this library is to provide simple and straight forward interfaces to the various shipping web services: FedEx, UPS, USPS, etc. (Only FedEx is supported at this time)

Before contacting me directly, please read:

If you find a bug or a problem please post it in the issues section. If you need help with something, please use google groups. I check both regularly and get emails when anything happens, so that is the best place to get help. This also benefits other people in the future with the same questions / problems. Thank you.

Install & use¶ ↑

Install the gem from rubyforge:

sudo gem install shippinglogic

Now just include it in your project and you are ready to go.

You can also install this as a plugin:

script/plugin install git://github.com/binarylogic/shippinglogic.git

See below for usage examples.

Simple tracking example¶ ↑

What I think is unique about this library is it’s usage / syntax:

fedex = Shippinglogic::FedEx.new(key, password, account, meter)
tracking = fedex.track(:tracking_number => "XXXXXXXXXXXXXXXXX")
# => A proxy object that delegates calls to an array of Shippinglogic::FedEx::Track::Event objects

tracking.tracking_number
# => "XXXXXXXXXXXXXXXXX"

tracking.tracking_number = "YYYYYYYYYYYYYYYYYY"
# => "YYYYYYYYYYYYYYYYYY"

tracking.status
# => "Delivered"

tracking.signature_name
# => "KKING"

tracking.events.first
# => #<Shippinglogic::FedEx::Track::Event @postal_code="95817", @name="Delivered", @state="CA", @residential=false,
#    @city="Sacramento", @type="DL", @country="US", @occured_at=Mon Dec 08 10:43:37 -0500 2008>

tracking.events.first.name
# => "Delivered"

Calls to the web services are lazy¶ ↑

In our above example, you will notice we are able to access attributes, while at the same time able to treat the object as an array. That’s because the object is not actually an array, it acts as a proxy for the underlying array.

That being said, a request is not sent to FedEx until we need to deal with the underlying array. Meaning it’s lazy, which is more efficient. Most would think the request to FedEx was sent when we initialized the object. This is not the case. The request to FedEx was sent when we executed “tracking.first”.

This is similar to how ActiveRecord’s association proxies work. When you call “user.orders” no database activity occurs until you actually use the object (Ex: user.orders.each).

Flexibility¶ ↑

You will notice above we assign the result of the ‘track’ method to a variable called ‘tracking’. That object has more to it:

# Initializing
tracking = fedex.track(:tracking_number => "XXXXXXXXXXXXX")
tracking.tracking_number
# => "XXXXXXXXXXXXX"

# Attribute accessors
tracking.tracking_number = "YYYYYYYYYYYYYYY"
tracking.tracking_number
# => "YYYYYYYYYYYYYYY"

# Mass attribute setting
tracking.attributes = {:tracking_number => "ZZZZZZZZZZZZZZZZ"}
tracking.tracking_number
# => "ZZZZZZZZZZZZZZZZ"

tracking.attributes
# => {:tracking_number => "ZZZZZZZZZZZZZZZZ"}

Available services and their features¶ ↑

This library is still very new, as a result only FedEx is supported at this time. More will come.

I spent a lot of time on the documentation, for examples of how to use each service please see the docs for their respective classes.

FedEx¶ ↑

  1. Tracking - See Shippinglogic::Fedex::Track

  2. Signature proof of delivery - See Shippinglogic::Fedex::Signature

  3. Getting service rates - See Shippinglogic::Fedex::Rate

  4. Creating shipments w/ labels - See Shippinglogic::Fedex::Ship

  5. Canceling shipments - See Shippinglogic::Fedex::Cancel

Add your own services¶ ↑

Simply fork the project and make your changes. If you want to add support for a new service it is very straight forward. Checkout the code in Shippinglogic::Fedex::Track, it very simple and easy to follow. It’s a great place to start because its the simplest of services.

Interface integration¶ ↑

What’s nice about having an object is that you can pass it around. Let’s say you wanted to add simple FedEx tracking functionality to your app:

class TrackingController < ApplicationController
  def new
    @tracking_details = fedex.track(params[:tracking])
  end

  def create
    @tracking_details = fedex.track(params[:tracking])
    render :action => :new if !@tracking.successful?
  end

  private
    def fedex
      @fedex ||= Shippinglogic::FedEx.new(key, password, account, meter)
    end
end

That’s pretty simple. Now check out your form:

# new.html.haml
- form_for @tracking_details do |f|
  = f.error_messages
  = f.text_field :tracking_number
  = f.submit "Track"

Then your results:

# create.html.haml
.signature_name= @tracking_details.signature_name
- @tracking_details.events.each do |event|
  .event
    .name= event.name
    .occured_at= event.occured_at.to_s(:long)
    .location== #{event.city}, #{event.state} #{event.postal_code}, #{event.country}
    .residential= event.residential ? "Yes" : "No"

Leave abstraction to your application¶ ↑

Here is what I did in an application of mine and it worked out great. I also have complete control of what I’m doing and the library is not limiting me:

class Shipment < ActiveRecord::Base
  class Service
    attr_accessor :carrier, :name, "delivered_by, :rate
  end

  def services
    @services ||= fedex_services # + some_other_services
  end

  private
    def fedex_services
      rate_options = {} # replace me with your own options accepted by Shippinglogic::FedEx::Rate
      fedex.rate(rate_options).collect do |rate|
        service = Service.new
        service.carrier = :fedex
        serivce.name = rate.name
        service.rate = rate.rate
        service.delivered_by = rate.delivered_by
        service
      end
    end
end
