У меня есть метод класса authenticate, который работает с классом User.
def self.authenticate(email:, password:)
result = DatabaseConnection.query("SELECT * FROM users WHERE email = '#{email}'")
User.new(result[0]['id'], result[0]['email'])
end
У меня есть тест Rspec;
feature 'authentication' do
it 'a user can sign in' do
User.create(email: 'test@example.com', password: 'password123')
visit 'sessions/new'
fill_in(:email, with: 'test@example.com')
fill_in(:password, with: 'password123')
click_button 'Sign In'
expect(page).to have_content 'Welcome, test@example.com'
end
end
При запуске Rspec я получаю следующую ошибку:
1) authentication a user can sign in
Failure/Error:
def initialize(id:, email:)
@id = id
@email = email
end
ArgumentError:
wrong number of arguments (given 2, expected 0)

Ниже мое приложение Sinatra;

class BookmarkManager < Sinatra::Base
enable :sessions, :method_override

@user = User.find(session[:user_id])
@bookmarks = Bookmark.all
erb :'bookmarks/index'

Ниже приведен полный класс пользователя
require_relative './database_connection'
require 'bcrypt'
class User
def self.create(email:, password:)
encypted_password = BCrypt::Password.create(password
)
result = DatabaseConnection.query("INSERT INTO users (email, password) VALUES('#{email}', '#{encypted_password}') RETURNING id, email;")
User.new(id: result[0]['id'], email: result[0]['email'])
end
attr_reader :id, :email
def initialize(id:, email:)
@id = id
@email = email
end
def self.authenticate(email:, password:)
result = DatabaseConnection.query("SELECT * FROM users WHERE email = '#{email}'")
User.new(result[0]['id'], result[0]['email'])
end
def self.find(id)
return nil unless id
result = DatabaseConnection.query("SELECT * FROM users WHERE id = #{id}")
User.new(
id: result[0]['id'],
email: result[0]['email'])
end
end
Я не понимаю, почему Rspec говорит, что он ожидает 0 аргументов, когда для метода initialize
явно требуется двааргументы (идентификатор и адрес электронной почты)?Мне нужно взять идентификатор и метод электронной почты от authenticate
и доставить его на initialize
.Я думал, что это то, что я делал, но Rspec и sinatra говорят иначе.
Спасибо, заранее.
