15 += Migrating EOF -> Squeryl =
16 +
17 +In keeping with the strong-typed philosophy of Scala, Squeryl has no dynamic component like EOF (i.e an EO model file).
18 +
19 +EOF has the ability to generate classes in Java (and in Objective-C prior to WebObjects 4.5) as enforcing type has become customary in enterprise environments. We may exploit this feature of EOF to generate a Squeryl schema.
20 +
21 +1. Create a .eogen file for your EO model as normal. Only set the ##File Names## extension to "scala".
22 +1. Use the Squeryl EO Templates:
23 +
24 +*
25 +** Entity.eotemplate [[template>>WOL:Squeryl _Entity.eotemplate]]
26 +** Entity.eotemplate [[template>>WOL:Squeryl Entity.eotemplate]]
