我有一个基于Ruby on Rails的API。目前的逻辑是设计密码重置功能。以下是查找用户并重置密码的代码块：
def update_password_by_token
@user = User.find_by_reset_password_token!(params[:id])
if @user.reset_password_sent_at < 2.hours.ago
render status: 422, json: {}
else
@user.password = params[:password]
@user.password_confirmation = params[:confirm_password]
if @user.save
render status: 200, json: {}
else
render status: 422, json: {}
end
end
end
这里是Android向API发送参数的过程
{
"password":"newpassword",
"confirm_password":"newpassword",
"id":"Upn0QHKNy858yMK1J8x1KA"
}
进一步深入研究后，我拿到了令牌并启动了Rails控制台。
@user = User.find_by_reset_password_token!("Upn0QHKNy858yMK1J8x1KA")
User Load (1.5ms) SELECT "users".* FROM "users" WHERE
"users"."deleted_at" IS NULL AND "users"."reset_password_token" = $1
LIMIT $2 [["reset_password_token", "CtW8XFYUdX3d9J7H1rtfUQ"], ["LIMIT",
1]]

我在部署的代码中是否有做错的地方？请问有人能给予建议吗？提前感谢。
@user是空值，而你正在对空值调用password_confirmation设置器。如果 @user 是空值，为什么它不会在@user.password =上中断，我就无法理解了。 - ray
