Ruby on Rails Controller Error in Search - ruby-on-rails

Question

I am facing the below error after I removed two fields middle_name, last_name from the Student migration thru another migration. below are the errors.
Searchlogic::NamedScopes::OrConditions::UnknownConditionError in StudentController#advanced_search
The condition 'last_name' is not a valid condition, we could not find any scopes that match this.

Answer 1

Thanks for the replies, The problem solved.
The problem was in the index migration, actually I removed the columns from the create migration but it was already there in index migration.

Answer 2

Dude that code is huge and very unlikely that someone will understand it by reading it one time..
Install rubocop or some other lint tool and clean that mess.
