Creating a FactoryBot Hash model with complicated structure, including multiple nested attributes - ruby

Question

I'm implementing a set of Cucumber driven API tests and stumbled into one specific model that has a few nested elements, like this:
factory :human_being, class: Hash do
human {
name {
first_name { Faker::Name.first_name }
last_name { Faker::Name.last_name }
}
age { rand(1..100) }
}
initialize_with { attributes }
end
The result I wanted to achieve should look like this:
{
:human => {
:name => {
:first_name => "mike",
:last_name => "blob"
},
:age => 16
}
}
I am invoking creation using FactoryBot.build(:human_being) and I get undefined method 'name' for #<FactoryBot::SyntaxRunner:0x00007fd640a39a80>
My env.rb has the World(FactoryBot::Syntax::Methods) / FactoryBot.find_definitions lines.
I've lurked through a few answers regarding the nested attributes / associations / traits but I didn't find a proper way to get what I want. Sorry if the post is duplicated and thanks in advance for help.

Answer 1

Okay, seems that I've found the solution right after posting the question. Currently the following model creates the Hash I described in the question:
factory :human_being, class: Hash do
human { {
name: {
first_name: Faker::Name.first_name,
last_name: Faker::Name.last_name,
},
age: rand(1..100),
sex: %w(male female other).sample
} }
initialize_with { attributes }
end
Although I'm not sure it is a completely correct answer from guidelines perspective, but at least it works for my exact case.
source (See 'Defining factories'): Because of the block syntax in Ruby, defining attributes as Hashes (for serialized/JSON columns, for example) requires two sets of curly brackets:
factory :program do
configuration { { auto_resolve: false, auto_define: true } }
end
