Elmas

Elmas means diamond, but in this case it's an API wrapper for Exact Online. This gem was created by @Marthyn, Hoppinger and a few people.

DISCLAIMER

As of 25th of May, 2FA will be mandatory for all Exact Online accounts. Therefor the auto authorize method with which you could simulate an App 2 App connection will not work anymore. Hoppinger is working on a new solution. The methods will stay available but probably won't work and will show a deprecation warning. Read more about it here

Contributers

Thanks for helping! If you want to contribute read through this readme how to!

Installation

Add this line to your application's Gemfile:

gem 'elmas'

And then execute:

$ bundle

Or install it yourself as:

$ gem install elmas

Authorization and Setup

You have to have an Exact Online account and an app setup to connect with.

You have to set a few variables to make a connection possible. I'd suggest using environment variables set with dotenv for that.

Then configure Elmas like this (take these values from your app that you setup at apps.exactonline.com)

Elmas.configure do |config|
  config.client_id = ENV['CLIENT_ID']
  config.client_secret = ENV['CLIENT_SECRET']
  config.redirect_uri = ENV['REDIRECT_URI']
end

You then have to retrieve an access token for the user you want to login with. You can setup a user facing OAUTH2 flow or set the access_token and/or refresh token on the go.

Elmas.configure do |config|
  config.access_token = "42"
  config.refresh_token = "42"
end

Once you've set your access tokens you should be able to do requests. You'll need a division number, you can retrieve that with the following line of code:

get("/Current/Me", no_division: true).results.first.current_division

Logger

The default logger is STDOUT. A custom logger can be be configured.

  dir = File.dirname("./tmp/errors.log")
  FileUtils.mkdir_p(dir) unless File.directory?(dir)

  Elmas.configure do |config|
    config.logger = ::Logger.new("./tmp/errors.log", "daily")
  end

Accessing the API

We can retrieve data from the API using the following syntax.

The query will return an Elmas::ResultSet which contains up to 60 records and a method to retrieve the next page of results. Unfortunately the ExactOnline API does not allow us to retrieve a specific page or define how many records we want to retrieve at a time.

# Query the API and return an Elmas::ResultSet
accounts = Elmas::Account.new.find_all

# Return an array of accounts
accounts.records

If the query results in more than 60 records the next set can be retrieved using the next_page method.

# Return an Elmas::ResultSet containing the next page's records
accounts.next_page

Filter and sort results

Filtering result sets can be done by adding attributes to the initializer and then using find_by. Filters accept a single value or an array of values.

# Find the account with code 123
accounts = Elmas::Account.new(code: '123').find_by(filters: [:code])

# Find the accounts with code 123 and 345
accounts = Elmas::Account.new(code: ['123', '345']).find_by(filters: [:code])

You can also match on values "greater than" or "less than" by specifying gt or lt:

# Find all AgingReceivables with an amount greater than 0 in the third age range
Elmas::AgingReceivablesList.new(age_group3_amount: { gt: 0 }).find_by(filters: [:age_group3_amount])

Results can be sorted in the same way

# Return all accounts sorted by first name
accounts = Elmas::Account.new.find_all(order_by: :first_name)

Filters and sorting can also be combined

# Return accounts with code 123 and 345 sorted by first name
accounts = Elmas::Account.new(code: ['123', '345']).find_by(filters: [:code], order_by: :first_name)

To find an individual record by its ID the find method can be used

# Return the account with guid
account = Elmas::Account.new(id: '9e3a078e-55dc-40f4-a490-1875400a3e10').find

For more information on this way of selecting data look here http://www.odata.org/

Creating new records

Use the initializer method followed by 'save' to create a new record:

# Create a new contact
contact = Elmas::Contact.new(first_name: "Karel", last_name: "Appel", account: "8d87c8c5-f1c6-495c-b6af-d5ba396873b5"  )
contact.save

Projects and Time Tracking

Project Types:

  • :type=>2, :type_description=>"Fixed price"
  • :type=>3, :type_description=>"Time and Material"
  • :type=>4, :type_description=>"Non billable"
  • :type=>5, :type_description=>"Prepaid"

To create a new project

project = Elmas::Project.new(code: "PROJ902343", description: "Great project", account: "8d87c8c5-f1c6-495c-b6af-d5ba396873b5", type: 2 )
project.save

To submit a new time transaction

hours = Elmas::TimeTransaction.new(account: "8d87c8c5-f1c6-495c-b6af-d5ba396873b5", item: "eb73942a-53c0-4ee9-bbb2-6d985814a1b1", quantity: 3.0, notes: "")
hours.save

SalesInvoice flow

SalesInvoices have a relationship with SalesInvoiceLines. A SalesInvoice has many SalesInvoiceLines and a SalesInvoiceLine belongs to a SalesInvoice. To create a valid SalesInvoice you need to embed the SalesInvoiceLines

sales_invoice = Elmas::SalesInvoice.new(journal: "id of your journal", ordered_by: "id of customer")

Now it still needs SalesInvoiceLines

sales_invoice_lines = []
sales_invoice_lines << Elmas::SalesInvoiceLine.new(item: "id of item being sold") # do this for each item you want in the invoice.
sales_invoice.sales_invoice_lines = sales_invoice_lines

Now you can save the SalesInvoice and it will be parsed to the following

sales_invoice.save
# Sanitized object: {"Journal"=>"id of your journal", "OrderedBy"=>"id of customer", "SalesInvoiceLines"=>[{"Item"=>"id of item being sold"}]}

If you have a SalesInvoice with an id(so saved before already), you can also create invoice lines without embedding

sales_invoice = Elmas::SalesInvoice.new({id: "1"}).first
sales_invoice_line = Elmas::SalesInvoiceLine.new(invoice_ID: sales_invoice, item: "42")
sales_invoice.save
# Sanitized object: {"Item"=>"42", "InvoiceID"=>"1"}

For many resources there are mandatory attributes, you can see that in the classes for every resource. For example for Contact: https://github.com/exactonline/exactonline-api-ruby-client/blob/master/lib/elmas/resources/contact.rb

###Divisions and Endpoints

Usually in the exact wrapper you need a division number, this one will be set on authorization checks (with /Current/Me endpoint). Sometimes you need to do a request without the division number, or even without the standard /api/v1 endpoint. Like so:

response = Elmas.get('/api/oauth2/token', no_endpoint: true, no_division: true)
response = Elmas.get('/Current/Me', no_division: true)

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Contributing

  1. Fork it ( https://github.com/[my-github-username]/elmas/fork )
  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 a new Pull Request

Testing

We use Rspec for normal unit testing. We aim for coverage above 90%. Also the current suite should succeed when you commit something. We use Rubocop for style checking, this should also succeed before you commit anything.

We're also experimenting with Mutation testing, which alters your code to test if your specs fail when there's faulty code. This is important when you alter a vital part of the code, make sure the mutation percentage is higher than 80%. To run a part of the code with mutant run the follwing mutant --include lib/elmas --require elmas --use rspec Elmas::ClassYoureWorkingOn

To test the vital classes run this mutant --include lib --require elmas --use rspec Elmas::Response Elmas::Client Elmas::Utils Elmas::Resource Elmas::Request Elmas::Parser Elmas::Config This will take a few minutes

When you're editing code it's advised you run guard, which watches file changes and automatically runs Rspec and Rubocop.
