Silverstripe version :4.7
I have migrated a silverstripe project from version 4.1.2 to 4.7.
I faced an issue on,
Object->__call() : the method ‘where’ does not exist on ‘Silverstripe/ORM/UnsavedRelationList’
However I fixed the issue by adding private static $searchable_fields.
But only 5 fields appeared from them in to the admin side search field.
How do I solve this issue?
I am not very familiar with silverstripe framework.
Thank you.
