Rails重定向取决于登录状态

Question

我的rails应用程序中有一个联系表单.现在它只是重定向到主页,无论如何.如果用户已登录,我想重定向到user_path,如果不是,我想重定向到主页..我该怎么做？

*使用设计

contact_controller

  def create
    @message = Message.new(params[:message])

    if @message.valid?
      NotificationsMailer.new_message(@message).deliver
      redirect_to(user_path, :notice => "Message was successfully sent.")
    else
      flash.now.alert = "Please fill all fields."
      render :new
    end
  end

end

Answer 1

如果他们已登录,您可以重定向到其他地方:

if current_user
    redirect_to(user_path, :notice => "Message was successfully sent.")
else
    redirect_to root_path
end

假设您current_xxx的设置为" user"
