I'm trying to create a simple model and spec for the validations and it seems the ActiveModel::Validations are not working. A simple case is this:

Model:
class Account
include Mongoid::Document
include ActiveModel::Validations

field :email, type: String

validates :email, presence: true

end

Spec:
require 'rails_helper'

RSpec.describe Account, type: :model do
it "errors when with no id" do
expect

{Account.create!(email: 'test@gmail.com')}

.to raise_error(Mongoid::Errors::Validations, /Validation of Account failed./)
end
end
