In the example above you have created 3 groups. The Group class has a has_many :tipo_atividades relationship

You should have the instance of a Grupo example:

# pegando o útimo grupo criado
grupo3 = Grupo.last
grupo3.tipo_atividades.create(nome: 'Palestra')

or

# pegando os últimos 3 grupos criados
Grupo.last(3).each do |grupo|
  grupo.tipo_atividades.create(nome: 'Palestra')
end

Using the has_many method
