How best to handle custom fields defaults and category setting logs

Development

Yeah this is tricky. I suppose most plugins don’t run into this because their ‘default’ for the category setting is a null value.

Did you have an idea for a core API change which could help improve the situation?

Totally untested, but I think we might be able to swing something right now by using a raw HTML input field (note lowercase input instead of Ember’s two-way-bound <Input component).

<input
  value={{or category.custom_fields.my_field "default value"}}
  {{on "change" this.updateMyFieldValue}}
/>

With that strategy, we have control over how values are read/written to the model instance. So, if a value is set to the default in the UI, we can write that as ‘null’ in the custom fields:

@action
updateMyFieldValue(event){
  let newValue = event.target.value;
  if(newValue === "default value"){
    newValue = null;
  }

  this.category.set("custom_fields.my_field", newValue);
}

(and then you would remove the default value configuration you described in (1) of the OP)
