ActiveRecord::NotNullViolation on specs

[fladson]

Hi, first thanks for the great work on this, it's very easy to setup.

I am using this on a devise model with rails 5 and so far it's all working fine, the only issue is when I try to create/save a record on the specs.

This is what I have:
schema

  create_table "users", force: :cascade do |t|
    ...
    t.string "encrypted_session", default: "", null: false
    t.string "encrypted_session_iv"
  end

model

class User < ApplicationRecord
  attr_encrypted :session, key: Rails.application.secrets.secret_key_attr_encrypt
  validates :session, presence: true
end

spec

require "rails_helper"

RSpec.describe User, type: :model do
  it { is_expected.to validate_presence_of(:session) }

  describe ".session encryption" do
    # this is fine
    it "assigns an encrypted value to encrypted_session and encrypted_session_iv" do
      user = User.new(session: Faker::Internet.password)

      expect(user.encrypted_session).not_to be_empty
      expect(user.encrypted_session_iv).not_to be_empty
    end

    it "returns the correct value after save" do
      session = Faker::Internet.password
      user = build(:user, session: session)
      binding.pry
      user.save

      expect(user.session).to eq(session)
    end
  end
end

the pry inspection

[1] pry(#<RSpec::ExampleGroups::User::SessionEncryption>)> user
=> #<User id: nil, email: "[email protected]", created_at: nil, updated_at: nil, session: nil>
[2] pry(#<RSpec::ExampleGroups::User::SessionEncryption>)> session
=> "Vp4q8fOoL3Np"
[3] pry(#<RSpec::ExampleGroups::User::SessionEncryption>)> user.session
=> "Vp4q8fOoL3Np"

The error

Failure/Error: user.save

     ActiveRecord::NotNullViolation:
       PG::NotNullViolation: ERROR:  null value in column "session" violates not-null constraint

The console and controller creation is fine
I've tried to put attribute :session at the model, but no success

Thanks for the help

@fladson Any luck figuring this error out?

This seems to be related to #335, i.e. how the attribute is assigned according to Rails attribute semantics.
