Question

As per rails guides says ActiveRecord::AssociationTypeMismatch should be raised only when there is association mismatch but in my case its something new..

Below is exception :

ActiveRecord::AssociationTypeMismatch (Service(#50963840) expected, got Service(#70493480)):

Can somebody explain what could be the possible issue ??

Answer 1

It was my mistake .. i was referring service association which wasn’t actually service object 🙂
