Symfony keeping objects old and new value(after form submit) [closed]

  default-value, dto, forms, object, symfony

Is there a way I can keep the old and new entity object values with relations(after form submit) in Symfony and compare them to see the changes only. Thanks!

I was thinking for mapped=”false” to form fields, but not sure how to pass the collection data to entry form type, or maybe it could be done with Data transfer object.
