Persistent adapter

[alexbiehl]

Hello,

I have a fully specified model using persistent from the yesod framework and currently I am evaluating available query DSLs. Do you think it would be possible to write adapters for relational-record to use it with persistent? That would make relational-record way more easily usable for me and probably many other people.

Thank you,
Alex

I'm also curious whether relational-record could function as a reasonable stand-in for esqueleto

@rehno-lindeque a glance over the code reveals relational-query-hdbc is itself an adapter for relational-query. I don't know what is needed exactly but it supplies ToSql instances for hdbcs record representation.

Maybe it wouldn't be too much work to make it work with PersistValues but I cannot say exactly yet.
