Konto API Rails Validator

This library is a wrapper for the Konto API (https://www.kontoapi.de/). It provides a validation method for ActiveRecord models that checks if a given account number and bank code represent a valid combination.

INSTALLATION

$ [sudo] gem install kontoapi-rails

USAGE

Add an initializer (e.g. kontoapi.rb) in config/initializers:

KontoAPI.setup do |config|
  # mandatory
  config.api_key = '<your-api-key>' # get one at https://www.kontoapi.de/
  # optional (with defaults)
  config.timeout = 10
  config.disable_for = ['development', 'test']
end

Then, in one of the models you want to validate bank account data with:

class PaymentData < ActiveRecord::Base

  # other validations
  validates :account_number, :bank_code, :presence => true

  # account data validation
  # (really just a shortcut for `validates_with KontoAPI::BankAccountValidator`)
  # Takes any of the following options (the defaults are shown here):
  #   :account_number_field => :account_number,
  #   :bank_code_field      => :bank_code,
  #   :allow_nil            => true,    <-- don't validate if one of them is nil
  #   :on_timeout           => :ignore  <-- do nothing if a timeout occurs, others:
  #                            :fail    <-- throw a validation error
  #                            :retry   <-- (not supported yet)
  #
  # If validations fails, an error within the standard ActiveRecord I18n scopes
  # will be added to the :account_number_field:
  # :invalid <-- if it is invalid
  # :timeout <-- if :on_timeout is set to :fail and the api call timed out
  validates_bank_account
  
  # IBAN validation
  # Check if the given IBAN is valid
  # Takes any of the following options (the defaults are shown here):
  #   :allow_nil            => true,    <-- don't validate if nil
  #   :on_timeout           => :ignore  <-- do nothing if a timeout occurs, others:
  #                            :fail    <-- throw a validation error
  #                            :retry   <-- (not supported yet)
  validates_iban :iban
  
  # BIC validation
  # Check if the given BIC exists
  # Takes any of the following options (the defaults are shown here):
  #   :allow_nil            => true,    <-- don't validate if nil
  #   :on_timeout           => :ignore  <-- do nothing if a timeout occurs, others:
  #                            :fail    <-- throw a validation error
  #                            :retry   <-- (not supported yet)
  validates_bic :bic

  # Combined IBAN & BIC validation
  # Check if the given BIC exists, the IBAN is valid and if they match
  # Takes any of the following options (the defaults are shown here):
  #   :allow_nil            => true,    <-- don't validate if both are nil
  #   :on_timeout           => :ignore  <-- do nothing if a timeout occurs, others:
  #                            :fail    <-- throw a validation error
  #                            :retry   <-- (not supported yet)
  validates_iban_and_bic :iban, :bic

end

And if you want to autocomplete the bank name:

class PaymentData < ActiveRecord::Base

  # bank name autocompletion
  # takes any of the following options (the defaults are shown here):
  #   :bank_code_field      => :bank_code,
  #   :bank_name_field      => :bank_name,
  #   :always_overwrite     => false,         <-- autocomplete even if bank name already present
  #   :on_timeout           => :ignore        <-- do nothing if a timeout occurs, others:
  #                            :retry         <-- (not supported yet)
  #                             'any string'  <-- use this string as the value
  autocomplete_bank_name

end
