Could not find implicit value for parameter builder: Shapeless.Lazy

[abhitechdojo]

Hello,

I wrote the following code

val schema = AvroSchema[SalesRecord]
val output = AvroOutputStream[SalesRecord](new File(outputLocation))
output.write(salesList)
output.flush
output.close

But this throws a compile time error

could not find implicit value for parameter builder: shapeless.Laxy[com.sksamuel.avro4s.AvroSchema[...]]

not enough arguments for method apply: .... Unspecified value parameter builder.

[sksamuel]

Can you give me the definition for sales record.

It might only work on case classes. I'm not sure if shapeless can find a Generic for a non case class. If you're on scala 2.11 can you try making it a case class. On 6 Feb 2016 04:04, "abhitechdojo" notifications@github.com wrote:

don’t the case classes have a 22 field limitation? My sales record is much wider than that.

I would try to convert this into a case class and break down the sales record into smaller entities.

[sksamuel]

Looks like the private fields are throwing shapeless off. I can get it to work as a normal (non case) class, without the privates. Eg.

class SalesRecord(val saleId: Int, val sellerId: Int, val createDateStr: String, val vin: String, val make: String, val model: String, val year: Double, val tL: String, val clr: String, val tr: String, val eg: String, val iT: String, val tML: Option[String], val dO: Double, val sP: Double, val tG: Double, val fEG: Double, val bEG: Double, val cT: Option[String], val sT: Option[String], val cDStr: String, val dDStr: String, val rDStr: String, val pBID: String, val fN: Option[String], val mN: Option[String], val lN: Option[String], val fuN: Option[String], val ad: Option[String], val ct: Option[String], val st: Option[String], private val pCStr: String, val hPN: Option[String], val bPN: Option[String], val cPN: Option[String], val eA: Option[String], val eT: Option[String], val cN: Option[String], val sBID: Option[String], val sFN: Option[String], val sMN: Option[String], val sLN: Option[String], val sFuMN: Option[String], val sAd: Option[String], val sC: Option[String], val sS: Option[String], val sPC: Option[String], val sHPN: Option[String], val sBPN: Option[String], val sCPN: Option[String], val sEA: Option[String], val sET: Option[String], val sCN: Option[String])

This is fixed in release 1.3.0 if you want to try it.
