我使用slick-joda-mapper 2.2，slick 3.1和play 2.5油滑排序喬達日期
它映射喬達日期沒有任何問題。
import com.github.tototoshi.slick.PostgresJodaSupport._
trait QuoteMapping {
self: HasDatabaseConfigProvider[JdbcProfile] =>
import driver.api._
val quotes = TableQuery[Quotes]
class Quotes(tag: Tag) extends Table[Quote](tag, "QUOTE") {
def id = column[Long]("ID", O.PrimaryKey, O.AutoInc)
def startDate = column[LocalDate]("START_DATE") // All OK
def endDate = column[LocalDate]("END_DATE") // All OK
def pricePerDay = column[Double]("PRICE_PER_DAY")
def totalPrice = column[Double]("TOTAL_PRICE")
def * = (id.?, startDate, endDate, pricePerDay, totalPrice) <>(Quote.tupled, Quote.unapply)
}
}
是否有可能將浮動約會日期排序？
/** Return a page of Quote */
def list(page: Int = 0, pageSize: Int = 10, orderBy: Int = 1, filter: String = "%"): Future[Page[(Quote)]] = {
val offset = pageSize * page
var query =
quotes.filter(_.id.asColumnOf[String] like filter.toLowerCase)
.drop(offset)
.take(pageSize)
orderBy match {
case 1 => query = query.sortBy(_.id.asc)
case 2 => query = query.sortBy(_.startDate.asc) // no .asc method
case 3 => query = query.sortBy(_.endDate.asc) // no .asc method
case 4 => query = query.sortBy(_.pricePerDay.asc)
case 5 => query = query.sortBy(_.totalPrice.asc)
case -1 => query = query.sortBy(_.id.desc)
case -2 => query = query.sortBy(_.startDate.desc) // no .desc method
case -3 => query = query.sortBy(_.endDate.desc) // no .desc method
case -4 => query = query.sortBy(_.pricePerDay.desc)
case -5 => query = query.sortBy(_.totalPrice.desc)
}
for {
totalRows <- count(filter)
list = query.result
result <- db.run(list)
} yield Page(result, page, offset, totalRows, pageSize)
}
