设计覆盖会话控制器

Question

我想在用户尝试登录但未确认时添加一条消息，我想在通知部分显示此消息，基本上设计需要向我们提供此消息但在这种情况下我没有看到任何消息.所以我决定从会话控制器手动添加它是我的代码：

class SessionsController < Devise::SessionsController

  def new
    super
  end

  def create
    user = User.find_by_email(params[:user][:email])

    self.resource = warden.authenticate!(auth_options)
    set_flash_message(:notice, :signed_in) if is_flashing_format?
    sign_in(resource_name, resource)

    if user.confirmed_at.nil?
      flash[:notice] = "my message here"
    end
    yield resource if block_given?

    respond_with resource, location: after_sign_in_path_for(resource)
  end

end

问题是执行操作后 flash[:notice] 为空，在控制台中我有

如何显示此消息？

更简单的方法是在你的 application_controller 中添加 before_filter :confirmation_notice 并检查 current_user.confirmed？与否。

前::

before_filter :confirmation_notice

def confirmation_notice
  flash[:notice] = "my message here" unless current_user.confirmed?
end

不要忘记配置您的视图以显示此 Flash 通知。
