ruby on rails - Formatting to_json method for child object -

i have rails object product:

{     id: 1     name: 'soup' }

and customer object:

{     id: 20     name: 'ryans' }

they linked via:

class product < activerecord::base   belongs_to :customer

when call product.to_json(methods: [:customer]), get:

{     id: 1     name: 'soup',     customer: {         id: 20         name: 'ryans'     } }

but need in format:

{     id: 1     name: 'soup',     customer_name: 'ryans' }

is possible? i'm using rails v4.1.7

you can delegate nameto customer class

class product < activerecord::base   belongs_to :customer   delegate :name, to: :customer, prefix: true

you can do

product.to_json(methods: [:customer_name])
