我是OneMonth学习条纹支付的初学者。现在，我正在学习如何创建产品表并为数据库设定种子。到目前为止，一切顺利，直到我在运行rake db：seed
后遇到问题 Davids-MBP-2：one_month_stripe_payments DKP $ rake db：seed

任务：TOP =＆gt; DB：种子
（通过使用--trace运行任务查看完整跟踪）
我尝试过rake db：reset，然后rake：db migrate，然后再次rake db：seed。但我仍然有同样的错误。
有人可以帮我解决这个问题吗？我感觉卡住了，我不知道该怎么做。
非常感谢！

＆＃39;电子邮件已被拍摄＆＃39;表示您有一条记录，其中已存在相同的电子邮件。
执行Rails控制台并检查记录是否存在。 如果没有，请做rake db：drop - ＆gt; rake db：create - ＆gt; rake db：migrate - ＆gt; rake db：seed。这将解决您的问题。

执行rake db:reset时，rake db:drop - ＆gt; rake db:create - ＆gt; rake db:migrate - ＆gt; rake db:seed。
您不需要再次rake db:seed。
您可以通过rails c检查您的控制台，看看您是否已将数据置于种子内部。 Product.all
