Paper trail object changes and rails enums
问题
我正在处理一个旧项目中模型的版本问题。项目中几乎所有的枚举值都是整数。在使用object_changes跟踪更改时，这些值显示为整数，这对查看数据的最终用户来说不够清晰。
例如
class Article
has_paper_trail
enum status: {draft: 0, published: 1}
end
记录保存时，对象更改为 status :[0,1]
有没有一种方法可以保存或显示状态键而不是值？
英文:
I'm working on versioning models in an old project. almost all of the enum's values used in the project are integers. when tracking changes with object_changes the values are displayed as integers, which is not clear to the end user viewing this data.
for example
class Article
has_paper_trail
enum status: {draft: 0, published: 1}
end
the record is saved with object changes status :[0,1]
is there a way either to save or display the status key instead of the value?

可以通过使用以下代码获得枚举值的可读形式。
version = Article.first.versions.last
version.changeset["status"]
为了更进一步，迁移您的数据并将枚举值定义为 'status'，如下所示。
enum status: {draft: :draft, published: :published}
Rails 将值保存为字符串；因此，它的属性必须具有兼容的数据类型。
英文:
You can obtain the readable form of the enum value by using the following code.
version = Article.first.versions.last
version.changeset["status"]
To go even further, migrate your data and define your enums for 'status' as follows.
enum status: {draft: :draft, published: :published}
Rails will save the values as strings; therefore, its attribute must have a compatible data type.
