how can I get ALL records from route53? - ruby

Question

how can I get ALL records from route53?
referring code snippet here, which seemed to work for someone, however not clear to me: https://github.com/aws/aws-sdk-ruby/issues/620
Trying to get all (I have about ~7000 records) via resource record sets but can't seem to get the pagination to work with list_resource_record_sets. Here's what I have:
route53 = Aws::Route53::Client.new
response = route53.list_resource_record_sets({
start_record_name: fqdn(name),
start_record_type: type,
max_items: 100, # fyi - aws api maximum is 100 so we'll need to page
})
response.last_page?
response = response.next_page until response.last_page?
I verified I'm hooked into right region, I see the record I'm trying to get (so I can delete later) in aws console, but can't seem to get it through the api. I used this: https://github.com/aws/aws-sdk-ruby/issues/620 as a starting point.
Any ideas on what I'm doing wrong? Or is there an easier way, perhaps another method in the api I'm not finding, for me to get just the record I need given the hosted_zone_id, type and name?

The issue you linked is for the Ruby AWS SDK v2, but the latest is v3. It also looks like things may have changed around a bit since 2014, as I'm not seeing the #next_page or #last_page? methods in the v2 API or the v3 API.
Consider using the #next_record_name and #next_record_type from the response when #is_truncated is true. That's more consistent with how other paginations work in the Ruby AWS SDK, such as with DynamoDB scans for example.
Something like the following should work (though I don't have an AWS account with records to test it out):
route53 = Aws::Route53::Client.new
hosted_zone = ? # Required field according to the API docs
next_name = fqdn(name)
next_type = type
loop do
response = route53.list_resource_record_sets(
hosted_zone_id: hosted_zone,
start_record_name: next_name,
start_record_type: next_type,
max_items: 100, # fyi - aws api maximum is 100 so we'll need to page
)
records = response.resource_record_sets
# Break here if you find the record you want
# Also break if we've run out of pages
break unless response.is_truncated
next_name = response.next_record_name
next_type = response.next_record_type
end
