Ruby 如何在rails中将表单字段限制在一定数量范围内

我有这两个条件，不知道我应该使用regex还是有更好的rails助手方法

我想做的是

field1: to have any number between 1-31
field2: to have any number between 1-5

调用创建操作时，将检查此选项

欢迎提供任何指导。

在您各自的车型中尝试此功能

validates :field1, :inclusion => 1..31, on => :create
validates :field2, :inclusion => 1..5, on => :create

在您各自的型号中尝试此功能

validates :field1, :inclusion => 1..31, on => :create
validates :field2, :inclusion => 1..5, on => :create
