我在heroku上运行rake时遇到错误。我可以在当地运行耙子，但由于某种原因，这不适用于现场环境。我看过一些关于bigint整数的帖子，但我甚至不确定这个错误发生在哪里或为什么？

答案 0 :(得分：2)
"150000200000"是使用INSERT INTO "posts" ("body", "created_at", "external_url", "heading", "make", "mileage", "model", "price", "timestamp", "title_status", "transmission", "updated_at", "year")...语句插入的其中一个字段中的值。
相应字段应从integer更改为bigint以解决此问题。如果字段不必是数字，则更改为字符串。
问题不是在本地发生，而是在heroku上发生，很可能是因为Heroku刮擦进程是针对本地脚本中未包含的站点运行的。
最好添加额外的logging / puts语句，以确定哪个字段的值为"150000200000"，然后适当地处理该字段。
