Issue with Fluent: Property to Field Conversion

Hi. I can't find any information how model properties are mapped to their database representation. Can anyone point in the right direction?

I am having an issue with IP address stored as String in the Model failing to be saved in inet column in my pg instance.

Here is the error message I am getting:

message: column "original_ip" is of type inet but expression is of type text

Thanks for the help in advance!

It's done at the driver level, so in the Postgres instance in PostgresNIO.

You can see some of the mappings at and related files. That's the best place to start.

You can also see how Date mapping is handled at

That should give you an idea of how to create a PostgresInet type that you can use in your models
