推荐答案

这是因为它是以 user 而不是 customer 的身份通过的.我相信这是因为您使用的是 current_user ，它是一个 User 而不是 Customer (从代码中猜测).将其更改为 params.require(:user).permit(blah)

It is because it is coming through as user and not customer. Which I believe is because you are using current_user which is a User and not a Customer (guessing from the code). Change it to be params.require(:user).permit(blah)
