activerecord - How to query nested associations in rails -

-

my models campaign.rb

has_many: views_logs

user.rb

has_many :views_logs

views_log.rb

belongs_to :campaign belongs_to :user

i want campaign.first.views_logs.uniq.users.genders know query wrong want this

you need define direct relationship through parameter:

class modelname   has_many :views_logs   has_many :users through: :views_logs end

then can query this: model_name.user.where(gender: 'male')
