Mapping values in a Phoenix View

Hello 👋 ,

I have a couple of doubts, both related to mapping. I am using the [Ja Phoenix View].(https://hexdocs.pm/ja_serializer/JaSerializer.PhoenixView.html)

  1. The view is always displaying the id field. In my case this field is private and only used internally. Instead, we communicate with the uuid field. I would like to use by default the uuid field, and not overwrite the id in my controller before passing it to the view. Any ideas on how to do this?

  2. I smaller issue, I would like to add some fields in the view that are not directly related to the database record. How can I add a field in the view without specifying the value in the controller? Some keys are renamed in the view vs the database record.

Thanks for your time!

@hylkealons check out the JaSerializer.Serializer documentation, specifically the attributes/2 and id/2 callbacks - https://hexdocs.pm/ja_serializer/JaSerializer.Serializer.html#c:attributes/2
https://hexdocs.pm/ja_serializer/JaSerializer.Serializer.html#c:id/2

I think those should address both your questions.
