Вот что мы делаем (в основном взяты из аутентифицированной системы) ... это метод контроллера, который обрабатывает вход в систему, который мы используем ...
def login
if logged_in?
flash[:notice] = "You are already logged in."
redirect_to "/" and return
end
unless request.post?
render :layout => 'task' and return
end
self.current_user = User.authenticate(params[:login], params[:password])
if logged_in?
if params[:remember_me].to_i == 1
self.current_user.remember_me
cookies[:auth_token] = {:domain => "#{DOMAIN}", :value => self.current_user.remember_token , :expires => self.current_user.remember_token_expires_at }
else
self.current_user.forget_me
cookies.delete(:auth_token, :domain => "#{DOMAIN}")
cookies[:auth_token] = nil
end
current_user.last_seen_at = Time.now
current_user.save
session[:notice] = "You logged in successfully"
flash[:notice] = "You logged in successfully"
redirect_back_or_default(:controller => 'dashboard') and return
#redirect_back_or_default(:controller => 'index', :action => 'index') and return
else
if $failed_login_counter.add_attempt(params[:login]) > MAXIMUM_LOGIN_ATTEMPTS
logger.info("login rate limiter kicking in, #{MAXIMUM_LOGIN_ATTEMPTS} login attempts failed")
redirect_to "/denied.html" and return
end
flash[:error] = "Unable to authenticate username and password"
render(:layout => 'task') and return
end
end
И использовать это для выхода из системы
def logout
current_user.last_seen_at = Time.now
current_user.save
self.current_user.forget_me if logged_in?
cookies.delete(:auth_token, :domain => "#{DOMAIN}")
reset_session
flash[:notice] = "You have been logged out."
#redirect_to :back
redirect_back_or_default(:controller => 'index', :action => 'index') and return
end
Тогда - в вашем application.rb вам понадобится что-то вроде:
before_filter :login_from_cookie
def login_from_cookie
return unless cookies[:auth_token] && !logged_in?
user = User.find_by_remember_token(cookies[:auth_token])
if user && user.remember_token?
user.remember_me
self.current_user = user
cookies[:auth_token] = { :domain => "#{DOMAIN}", :value => self.current_user.remember_token , :expires => self.current_user.remember_token_expires_at }
flash[:notice] = "#{self.current_user.login}, you have logged in successfully"
end
end
И - в вашей модели User есть несколько методов, подобных этому:
# Encrypts some data with the salt.
def self.encrypt(password, salt)
Digest::SHA1.hexdigest("--#{salt}--#{password}--")
end
# Encrypts the password with the user salt
def encrypt(password)
self.class.encrypt(password, salt)
end
def remember_token?
remember_token_expires_at && Time.now.utc < remember_token_expires_at
end
# These create and unset the fields required for remembering users between browser closes
def remember_me
self.remember_token_expires_at = 2.weeks.from_now.utc
self.remember_token = encrypt("#{email}--#{remember_token_expires_at}")
save(false)
end
def forget_me
self.remember_token_expires_at = nil
self.remember_token = nil
save(false)
end
