ruby on rails - Getting Records Based on Count of Associated Model -

i want utilize statement following:

baseproduct.where(baseproduct.products.count => 1)

this doesn't work.i undefined method 'products' class xyz.

in rails console though, can do

baseproduct.first.products

and output.

how records associated model count 1?

associations:

class baseproduct < activerecord::base   has_many :products end  class product < activerecord::base   belongs_to :base_product end

please seek this

product.select('base_product_id, count(base_product_id) c').includes('base_product').group('products.base_product_id').having('c > 1')
