我想部署我的rails應用程序與heroku。我跑heroku run rake db:migrate，這工作得很好。然後我試着運行heroku run rake db:seed，我得到了這個錯誤：value too long for type character varying(255)。如何看到什麼屬性給我這個錯誤：價值太長的類型字符變化（255）
我翻遍了我的代碼，我很確定所有的字符串屬性都少於255個字符。我如何看到哪個屬性給我錯誤？

這看起來更像是一個電子表格而不是數據庫模式。我希望你的下一次「遷移」能使結構正常化至少3NF。 – wildplasser
我是新來的鐵軌，我不太熟悉我的選擇。這個想法是，我的網站爲每個學院都有一個頁面，我想通過擁有一個大學視圖並根據@ college.attribute更改視圖來保留我的代碼。用電子表格可以更容易嗎？如果是的話，我如何使用電子表格？ –
