【问题描述】：

我的风帆种子已配置为在模型下放置名称属性的字符串，但它反而使我的应用程序崩溃。

error: Bootstrap encountered an error: (see below)
error:
error: { UsageError: Invalid initial data for new records.
Details:
  Could not use one of the provided new records: Missing value for required attribute `name`.  Expected a string, but instead, got: undefined

  isOperational: true,

由于我的种子文件看起来像这样，我该如何解决这个问题。

    }
  ]
};

【解决方案1】：

我发现问题的原因是由于config/model.js 文件列出了migrate: 'drop' 而应该是migrate: 'alter'。我不知道为什么将其设置为drop 是错误的，但它不适用于drop 作为选项，只能用于safe 或alter。
