Hi Rick and thanks for your answer,
The problem is not the nested hash but the fact that there is no
assoiciation named :companies. Address belongs to :addressable... So
my query should read:
Address.all :joins => :addressable, :conditions => { :companies =>
{ :reseller => true }, :addresses => { :geocoded => true } }
But then I get an exception:
ActiveRecord::EagerLoadPolymorphicError: Can not eagerly load the
polymorphic association :addressable
