How to create additional records for the same subdomain

[zappiehost]

I read on examples/manage_records.php the following:

/*
 * In PowerDNS there's no such thing as 'updating' a record. Instead, just create a new record with the same name and
 * type, as this is the 'unique' combination for a record. The following example will change the IP for 'test2' from
 * '127.0.0.2' (see the example above) to  '127.0.1.2'.
 */

With this in mind, what is the best practice if we have an existing subdomain foo.bar.bz 1.2.3.4 and we want to add a second A record to the same subdomain without removing the first?

You need to append the new record to the existing one by retrieving it first, update the contents and save it. You can look at the example in this issue for exactly the same use case. It does what you want, but with a NS record.

So does this mean we have to write two different ways of adding two records

1. If the subdomain doesnt already exists, we need to use the ->create() method
2. if the subdomain does exists we need to loop through and modify the record by adding a new DNS entry inside?

Am i right with this logic?

Unfortunately, yes. However, if you've all the data in some way, you could also call create in both cases to overwrite the existing record.
