ruby-on-rails – Rails：使用Authlogic进行基本身份验证

设置authlogic后,在Application Controller中定义以下有用的与身份验证相关的帮助程序方法.

def current_user_session
  return @current_user_session if Defined?(@current_user_session)
  @current_user_session = UserSession.find
end

def current_user
  return @current_user if Defined?(@current_user)
  @current_user = current_user_session && current_user_session.record
end

def require_user
  unless current_user
    store_LOCATIOn
    flash[:notice] = "You must be logged in to access this page"
    redirect_to new_user_session_url
    return false
  end
end

def require_no_user
  if current_user
    store_LOCATIOn
    flash[:notice] = "You must be logged out to access this page"
    redirect_to root_url
    return false
  end
end

定义这些方法后,您可以指定要求用户登录的操作：

before_filter :require_user,:only => [:new,:edit]
