Detailed Description

template<typename OtherTable, typename ThroughTable>
class HasOneThrough< OtherTable, ThroughTable >

Represents a one-to-one relationship through a join table.

The OtherField parameter is the field in the join table that references the other record. The ThroughField parameter is the field in the join table that references the current record.
