Saving Unknown Attributes about store_model

[DmitryTsepelev]

Hi @ishields! Unfortunately, it's not possible right now, because no one asked for it before 🙂 If I'm not mistaken, the method was introduced to handle the situation when there is a legacy column with extra data you don't care, but don't want serialiser to crash.

It feels like the implementation is going to be fairly simple: when unknown attributes are found we store them to the unknown_attributes hash, in order to avoid erasing them we just need to change this line (to something line attributes.with_indifferent_access.merge(unknown_attributes).as_json(options)). Do you want to try it out? 🙂

Yea I can take a look! One thing that would be nice with this is if you then add the attribute that was unknown it translates it into it. And the other way around - if a model attribute is removed.

You mean you want to be able to add and unknown attribute to the model and have it saved? Something like:

class Configuration
  include StoreModel::Model

  attribute :model, :string
end

configuration = Configuration.new
configuration.model = "XR"
configuration.unknown.color = "red"
