mysql- Mysql2 ::错误：数据太长，无法在列1'列'描述

Question

我建立了一个刮板，它似乎不像我的描述长度。我将列更改为varchar（500），但没有骰子。我想我需要转换为文本，但我不知道如何。这对我来说有意义吗？谢谢！

错误 -

In the United States, United Kingdom and Canada, the term panini has been adopted to refer to a pressed and toasted sandwich; there is widespread availability and use of sandwich presses, often known as \"panini presses\" or \"toasted sandwich makers.\"', '/wiki/File:Italian_Sandwich.jpeg', 'Panini', '2013-05-03 01:10:08') (ActiveRecord::StatementInvalid)
