django.db.utils.DataError: (1406, "Data too long for column 'gender' at row 1")

全部报错代码

分析报错

没有具体的跳转, 但是文本是 gender 的问题因此可以断定是 gender 的长度问题

找到 所含 gender 的字段, 发现 长度确实有点小. female 是 6 位 超出了.因此报错

报错处理

更改 长度 为 10 然后 记得上传表更改之后再重新创建即可

django.db.utils.DataError: (1406, "Data too long for column 'gender' at row 1")的相关教程结束。
