Use Sales Force as an Active Model

ActiveForce

A ruby gem to interact with SalesForce as if it were Active Record. It uses Restforce to interact with the API, so it is fast and stable.

Installation

Add this line to your application's Gemfile:

gem 'active_force'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_force

Setup credentials

Restforce is used to interact with the API, so you will need to setup environment variables to set up credentials.

SALESFORCE_USERNAME       = [email protected]
SALESFORCE_PASSWORD       = your-sfdc-password
SALESFORCE_SECURITY_TOKEN = security-token
SALESFORCE_CLIENT_ID      = your-client-id
SALESFORCE_CLIENT_SECRET  = your-client-secret

You might be interested in dotenv-rails to set up those in development.

Usage

class Medication < ActiveForce::SObject

  field :name,             from: 'Name'

  field :max_dossage  # defaults to "Max_Dossage__c"
  field :updated_from

  ##
  # Table name is inferred from class name.
  #
  # self.table_name = 'Medication__c' # default one.

  ##
  # Validations
  #
  validates :name, :login, :email, presence: true

  # Use any validation from active record.
  # validates :text, length: { minimum: 2 }
  # validates :text, format: { with: /\A[a-zA-Z]+\z/, message: "only allows letters" }
  # validates :size, inclusion: { in: %w(small medium large),
  #   message: "%{value} is not a valid size" }

  ##
  # Callbacks
  #
  before_save :set_as_updated_from_rails

  private

  def set_as_updated_from_rails
    self.updated_from = 'Rails'
  end

end

Altenative you can try the generator. (requires setting up the connection)

rails generate active_force_model Medication__c

Associations

Has Many

class Account < ActiveForce::SObject
  has_many :pages

  # Use optional parameters in the declaration.

  has_many :medications,
    scoped_as: ->{ where("Discontinued__c > ? OR Discontinued__c = ?", Date.today.strftime("%Y-%m-%d"), nil) }

  has_many :today_log_entries,
    model: DailyLogEntry,
    scoped_as: ->{ where(date: Time.now.in_time_zone.strftime("%Y-%m-%d") }

  has_many :labs,
    scoped_as: ->{ where("Category__c = 'EMR' AND Date__c <> NULL").order('Date__c DESC') }

end

Belongs to

class Page < ActiveForce::SObject
  field :account_id,           from: 'Account__c'

  belongs_to :account
end

Querying

You can retrieve SObject from the database using chained conditions to build the query.

Account.where(web_enable: 1, contact_by: ['web', 'email']).limit(2)
#=> this will query "SELECT Id, Name, WebEnable__c
#                    FROM Account
#                    WHERE WebEnable__C = 1 AND ContactBy__c IN ('web','email')
#                    LIMIT 2

It is also possible to eager load associations:

Comment.includes(:post)

Model generator

When using rails, you can generate a model with all the fields you have on your SFDC table by running:

rails g active_force:model <table name>
