ForeignModelConditionBuilderField

Helper type to access sub-fields through ModelRef foreign key fields. Will join the foreign model table automatically if using any fields on there, other than the primary key, which can be read directly from the source.

Just like ConditionBuilder this automatically mirrors all DORM fields of the _foreign_ table, i.e. the referenced model type.

This type is returned by the ConditionBuilder. It does not define any members itself, it only defines all members of the referenced Model to be accessible. When operating on the primary key that is referenced to from the ModelRef foreign key, no join operation will be enforced, as the data is stored entirely in the table with the foreign key.
