Question

我想在用户尝试登录时添加消息并且未确认，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，这是我的代码：

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flash [：notice]在执行操作后为空，在控制台中我有

   (0.1ms)  begin transaction
   (0.2ms)  commit transaction

如何显示此消息？

Answer 1

更简单的做法是在application_controller中添加before_filter：confirmation_notice并检查current_user.confirmed是否正确？或不。

ex ::

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。
