Auchandirect::ScrAPI

A ruby gem providing, through scrapping, an API to the french www.auchandirect.fr online grocery

Add this line to your application's Gemfile:

gem 'auchandirect-scrAPI'

And then execute:

$ bundle

Or install it yourself as:

$ gem install auchandirect-scrAPI

This library should be production ready.

• It is automaticaly tested through Travis
• It should be daily tested through daily-travis to quickly detect modification at www.auchandirect.fr

This API has 2 main features :

• walking the store to collect all the different items in the different subsections
• Connecting with a user account in order to fill his cart

It is not currently possible to pay and validate an order through this API. In order to do so, a user must :

1. first disconnect from the API
2. only then reconnect with his account through a browser, and order his pre-filled cart

Suppose you'd want to fill your cart with all the pizzas available on the store, this is how you would do it :

cart = Auchandirect::ScrAPI::Cart.login('buyer@mail.org', 'password')

begin

  Auchandirect::ScrAPI::Items.browse.categories.each do |cat|
    cat.categories.each do |s_cat|
      s_cat.categories.each do |ss_cat|
        ss_cat.items.each do |item|

          if item.attributes[:name] =~ /pizza/i

            cart.add_to_cart(item.attributes[:remote_id])

          end
        end
      end
    end
  end

ensure

  ensure cart.logout

end

In order to make it possible for a web browser to automaticaly connect to auchandirect.fr (for example in an iframe, to pay for a cart that was previously filled with this gem on the server), the Auchandirect::ScrAPI::Cart class exposes enough information to generate the html that makes this possible. You can have a look at spec/lib/auchandirect/scrAPI/client_cart_shared_examples.rb for more details. This whole thing remains tricky and subject to failures though.

In order to run quicker and offline tests for the rest of your app, you can use Auchandirect::ScrAPI::DummyCart in place of a real cart. This cart is compatible with Storexplore's dummy store generators (see https://github.com/philou/storexplore).

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

• If you want to run the tests, you'll need valid auchandirect credentials. So first, head up to www.auchandirect.fr and create yourself an account if you don't yet have one.
• To run guard or rspec, you'll have to specify these credentials through environment variables :

AUCHANDIRECT_TEST_EMAIL=me@mail.com AUCHANDIRECT_TEST_PASSWORD=secret bundle exec rspec spec

• If you get tired of repeating this, you can create yourself a 'credentials' shell script at the root of the repo :

#!/bin/sh
AUCHANDIRECT_TEST_EMAIL=me@mail.com AUCHANDIRECT_TEST_PASSWORD=secret "$@"

• Make it exectuable chmod +x credentials
• You can now simply run any command with your credentials

./credentials bundle exec rspec spec
