Description
Hi there! I've been using Etso for a while now and it's a great solution to get an Ecto based project up and running in no time.
One thing that I'm missing is to be able to get the error that happens when trying to insert a duplicate entry. In other words, I get a changeset that is invalid, however, the errors property is empty. The impact is that I'm unable to show this error information on a form.
I've been dabbling a litte with the implementation in order to check if it's possible, and here are my findings.
First, the empty error is justified by the following line:
etso/lib/etso/adapter/behaviour/schema.ex
Line 24 in f25bdea
If I change that to this:
diff --git a/lib/etso/adapter/behaviour/schema.ex b/lib/etso/adapter/behaviour/schema.ex
index 6fe3992..fd8f7e1 100644
--- a/lib/etso/adapter/behaviour/schema.ex

ets_field_names = TableStructure.field_names(schema)
ets_changes = TableStructure.fields_to_tuple(ets_field_names, fields)

end %{

}What are your thoughts on that, is that something you wish to support?
