SpreeTemando

spree_temando adds support to Spree to calculate a shipping quote using Temando.

Add this line to your application's Gemfile:

gem 'spree_temando'

And then execute:

$ bundle
$ rake spree_temando:install:migrations
$ rake db:migrate

Or install it yourself as:

$ gem install spree_temando

Finally, in an initializer, set up your authentication keys :

Temando::Api::Base.config.username = ENV['TEMANDO_USERNAME']
Temando::Api::Base.config.password = ENV['TEMANDO_PASSWORD']

The extension adds a new Shipping calculator.

NOTE this extension assumes that all product dimensions are in centimetres, with weights in kilograms.

Add a new Shipping Method from the Spree Admin (under Configuration > Shipping Methods), and you can set the relevant calculator type to Temando.

There are a few options you must fill out :

• Origin Suburb - the suburb you will be shipping from.
• Origin Postcode - the postcode you will be shipping from.
• Express - select this to find the fastest & cheapest shipping quote.

It is possible to create multiple calculators with different settings - for example, a "Regular" method with Express disabled, and an "Express" method with Express enabled.

In the calculations, the extension always attempts to find the cheapest quote, but when Express is selected, only the quotes with the smallest maximum_eta are considered.

It's important to note that all products in the cart must have their dimensions filled out (height, length, depth, weight), otherwise Temando will not be able to quote.

Depending on how you actually fulfil the shipments, you might like to add some padding to the ETA days provided by Temando. This allows you to better manage customer expectations.

In this case, you have three fields to tweak:

• Minimum ETA - the minimum days it will take to ship and deliver. The days provided will never be less than this value.
• Pad Minimum - The number of days to pad the "Minimum ETA" by.
• Pad Maximum - the number of days to pad the "Maximum ETA" by.

For example, if you know it's always going to take at least 3 days to get an order boxed up before you can ship it, you might set each of the "pad" values to 3 days, turning a quote for 1-3 days into 4-6 days.

Another example is where you know there are frequently delays with your usual shipping provider. In this case, you might set the minimum ETA to 5, and set each of the padding values to 2. If temando offers a quote at 1-2 days, this will turn into 5-7.

In this case, the lowest number is forced by the minimum eta setting. The highest number is forced to the same value (as it's under 5) and then padded by 2.

To simplify all the options for feeding product data to Temando, you can define the Spree::Variant#populate_temando_item method, which will be called back after the Variant has been turned into a Temando Item.

A few examples are included below to give you a hint at the possibilities.

The temando API allows for items to be identified as eligible for optimisation (ie. they can be grouped together in a defined packaging size), or ineligible for optimisation (ie. already packed and can't be combined).

Because there are numerous different ways you might want to implement this logic in your site, you must calculate this from the Spree::Variant#populate_temando_item callback.

module VariantDecorator

  def populate_temando_item(item)
    item.packaging_optimization = %w( Bundle Free ).include?(product.shipping_category.try(:name)) ? "Y" : "N"

    item
  end

end
Spree::Variant.send(:include, VariantDecorator)

The above example assumes that you're using a shipping category to decide, and products in the "Bundle" or "Free" categories are optimisable.

A similar situation arises with the shipping packaging. Because different shipping methods are defined against different packaging types (eg. parcels, pallets, etc) you often need to drive these from the product categories.

To do this, you can adjust the Item returned by and set the correct shipping_packaging. (See the Temando API for details on valid values).

The Temando gem defaults to Parcel packaging type if nothing is explicitly set.

module VariantDecorator

  def populate_temando_item(item)
    case product.shipping_category.try(:name)
    when 'Pallet'
      item.shipping_packaging = 'Pallet'
      item.pallet_type        = 'Plain'
      item.pallet_nature      = 'Not Required'
    when 'Box'
      item.shipping_packaging = 'Box'
    else
      item.shipping_packaging = 'Parcel'
    end

    item
  end

end
Spree::Variant.send(:include, VariantDecorator)

The extension only makes requests to the Temando API when the order changes in some way - either address details, line items, or the like. This ensures that a customer going back and forth between the Address and Delivery pages does not bombard the Temando API with spurious requests.

However, each time the calculator is used does cause another request. For example, the example of two shipping methods above will cause two requests to the API for the relevant quotes, even though they expect the same data.
