When checking my work , I encounter the following:

There seems to be an error in your code: /usr/local/lib/ruby/gems/2.3.0/gems/activerecord-5.0.1/lib/active_record/relation/delegation.rb:123:in method_missing': undefined methodname=' for #<ActiveRecord::Associations::CollectionProxy []> (NoMethodError) from /usr/local/lib/ruby/gems/2.3.0/gems/activerecord-5.0.1/lib/active_record/relation/delegation.rb:93:in method_missing' from /workdir/playground.rb:3:in<top (required)>'

playground.rb
owner = Owner.first
pet = owner.pets
pet.name = 'milo'
