How can i update the ids field with this rethinkdb document structure? - rethinkdb

Question

Having trouble trying to update the ids field in the document structure:
[
[0] {
"rank" => nil,
"profile_id" => 3,
"daily_providers" => [
[0] {
"relationships" => [
[0] {
"relationship_type" => "friend",
"count" => 0
},
[1] {
"relationship_type" => "acquaintance",
"ids" => [],
"count" => 0
}
],
"countries" => [
[0] {
"country_name" => "United States",
"count" => 0
},
[1] {
"country_name" => "Great Britain",
"count" => 0
}
],
"provider_name" => "foo",
"date" => 20130912
},
[1] {
"provider_name" => "bar"
}
]
}
]

In JavaScript, you can do
r.db('test').table('test').get(3).update(function(doc) {
return {daily_providers: doc("daily_providers").changeAt(
0,
doc("daily_providers").nth(0).merge({
relationships: doc("daily_providers").nth(0)("relationships").changeAt(
1,
doc("daily_providers").nth(0)("relationships").nth(1).merge({
ids: [1]
})
)
})
)}
})
Which becomes in Ruby
r.db('test').table('test').get(3).update{ |doc|
{"daily_providers" => doc["daily_providers"].changeAt(
0,
doc["daily_providers"][0].merge({
"relationships" => doc["daily_providers"][0]["relationships"].changeAt(
1,
doc["daily_providers"][0]["relationships"][1].merge({
ids => [1]
})
)
})
)}
}
You should probably have another table for the daily providers and do joins.
That would make things way more simpler.
