Create a Rails application called company_contacts. The app will have a PostgreSQL database. Generate a model called Account that has a username, a password, and an email. All stories should have accompanying model specs. Developer Stories

    rails g model Account username:string password:string email:string
    rails db:migrate

As a developer, I need username, password, and email to be required.

    RSpec.describe Account, type: :model do
  it 'needs username, password, and email' do
    account = Account.create(username:'Learn123', password:'123ABC', email:'[email protected]')
    expect(account).to be_valid
  end
end

As a developer, I need every username to be at least 5 characters long.

it 'is not valid without minimum 5 characters' do
    account = Account.create(username:'1234')
    expect(account.errors[:username]).to_not be_empty
  end

As a developer, I need each username to be unique.

 it 'is does allow duplicate usernames' do
    Account.create(username:'Learn123', password:'123ABC', email:'[email protected]')
    account = Account.create(username:'Learn123', password:'123ABC', email:'[email protected]')
    # account = Account.create(username:'Learn123', password:'123ABC', email:'[email protected]')
    expect(account.errors[:username]).to_not be_empty
  end

As a developer, I need each password to be at least 6 characters long.

 it 'is not valid if under 6 characters' do
    account = Account.create(password:'12345')
    expect(account.errors[:password]).to_not be_empty
  end

As a developer, I need each password to be unique.

it 'is does allow duplicate password' do
    Account.create(username:'Learn123', password:'123ABC', email:'[email protected]')
    account = Account.create(username:'Learn123', password:'123ABC', email:'[email protected]')
    # account = Account.create(username:'Learn123', password:'123ABC', email:'[email protected]')
    expect(account.errors[:password]).to_not be_empty
  end

As a developer, I want my Account model to have many associated Addresses.

RSpec.describe Address, type: :model do
  it 'needs street_number, street_name, city, state, and zip' do
    address = Address.create(street_number:123, street_name:'first ave', city:'San Diego', state:'CA', zip:92121)
    expect(address).to be_valid
  end
end

As a developer, I want Address to have street_number, street_name, city, state, and zip attributes. The street_number and zip should be integers.

RSpec.describe Address, type: :model do
  it 'needs street_number, street_name, city, state, and zip' do
    address = Address.create(street_number:123, street_name:'first ave', city:'San Diego', state:'CA', zip:92121)
    expect(address).to be_valid
  end
end

As a developer, I want to validate the presence of all fields on Address.

class Address < ApplicationRecord
    belongs_to :account
    validates :street_number, :street_name, :city, :state, presence: true
end
