Models

If you need to create new models or customize existent ones, you can do it so at the app/models/custom folder. Keep in mind that for old models you'll need to firstly require the dependency.

For example for Madrid's City Hall fork its required to check the zip code's format (it always starts with 280 followed by 2 digits). That check is at app/models/custom/verification/residence.rb:

require_dependency Rails.root.join('app', 'models', 'verification', 'residence').to_s
class Verification::Residence
validate :postal_code_in_madrid
validate :residence_in_madrid
def postal_code_in_madrid
errors.add(:postal_code, I18n.t('verification.residence.new.error_not_allowed_postal_code')) unless valid_postal_code?
end
def residence_in_madrid
return if errors.any?
unless residency_valid?
errors.add(:residence_in_madrid, false)
store_failed_attempt
Lock.increase_tries(user)
end
end
private
def valid_postal_code?
postal_code =~ /^280/
end
end

Do not forget to cover your changes with a test at the spec/models/custom folder. Following the example we could create spec/models/custom/residence_spec.rb:

require 'rails_helper'
describe Verification::Residence do
let(:residence) { build(:verification_residence, document_number: "12345678Z") }
describe "verification" do
describe "postal code" do
it "should be valid with postal codes starting with 280" do
residence.postal_code = "28012"
residence.valid?
expect(residence.errors[:postal_code].size).to eq(0)
residence.postal_code = "28023"
residence.valid?
expect(residence.errors[:postal_code].size).to eq(0)
end
it "should not be valid with postal codes not starting with 280" do
residence.postal_code = "12345"
residence.valid?
expect(residence.errors[:postal_code].size).to eq(1)
residence.postal_code = "13280"
residence.valid?
expect(residence.errors[:postal_code].size).to eq(1)
expect(residence.errors[:postal_code]).to include("In order to be verified, you must be registered in the municipality of Madrid.")
end
end
end
end
