Rails - seeding data with has_many through association?

I have a seed file with the following code within it:

300.times do
  # create the customer
  customer = Customer.create([
    {customer_type_id: '1'}
  ])

  # create an address for the customer
  address = Address.create([
    {city: Faker::Address.city, country: 'UK'}
  ])
  postcode = Postcode.create([
    {value: Faker::Address.uk_postcode}
  ])
  name_number = NameNumber.create([
    {value: Random.rand(495)}
  ])
  street = Street.create([
    {value: Faker::Address.street_name + " " + Faker::Address.street_suffix}
  ])
  state = State.create([
    {value: Faker::Address.uk_county}
  ])

This works fine. I had hoped, however, to be able to do the following:

address = Address.create([
  {city: Faker::Address.city, country: 'UK'}
])
address.postcode = Postcode.create([
  {value: Faker::Address.uk_postcode}
])

Where I have created the address in the first line, and I am creating the postcode for the address in the second line. This, however, generates an error.

Could anyone suggest how I can do this?

Thanks!

EDIT: As requested, the error generated is:

rake db:seed
rake aborted!
undefined method `postcode=' for #<Array:0x007f9df1f26818>

Tasks: TOP => db:seed
(See full trace by running task with --trace)

You're passing an array to create, which creates one object for each hash of attributes in the array and returns the resulting array of objects. Since you're only creating one object at a time, simply remove the square brackets around your hash of attributes (and even the curly braces if you want) and it should work correctly:

address = Address.create(city: Faker::Address.city, country: 'UK')
