Play2-Pager

Pager support for Play2 application.

Target

Scala 2.11.x & 2.12.x Play 2.5.x & 2.6.x

Setup

libraryDependencies += "jp.t2v" %% "play2-pager"             % "0.2.0"
libraryDependencies += "jp.t2v" %% "play2-pager-scalikejdbc" % "0.2.0" // optional. it is useful when you use scalikejdbc.

How to use

1. add imports into templateImports and routesImport in your Play Project .sbt.

   lazy val sample = (project in file("sample")).
     enablePlugins(PlayScala).
     settings(
       // ...snip
       templateImports ++= Seq(
         "jp.t2v.lab.play2.pager._"
       ),
       routesImport ++= Seq(
         "jp.t2v.lab.play2.pager.Pager",
         "jp.t2v.lab.play2.pager.Bindables._"
       ),
     )

2. define implicit Sortable value of your entities.

   • default is default sorting key and direction.
   • acceptableKeys is sortable keys of the entity.

   package models.account
   
   import scalikejdbc._
   import org.joda.time.{DateTime, LocalDate}
   import jp.t2v.lab.play2.pager.{OrderType, Sortable}
   
   case class Account(id: Int, name: Name, email: EMail, birthday: LocalDate, createdAt: DateTime)
   
   object Account extends SQLSyntaxSupport[Account] {
   
     def apply(s: SyntaxProvider[Account])(rs: WrappedResultSet): Account = autoConstruct(rs, s)
   
     implicit object sortable extends Sortable[Account] {
       val default: (String, OrderType) = ("id", OrderType.Descending)
       val acceptableKeys: Set[String] = Set("id", "name", "email", "birthday", "createdAt")
     }
   
   }

3. define controller that receive a Pager of your entity.

     def index(pager: Pager[Account]) = Action {
       Ok(views.html.index(accountService.findAll(pager)))
     }

4. define service that returns a SearchResult of your entity.

   package models.account
   
   import jp.t2v.lab.play2.pager.{SearchResult, Pager}
   
   class AccountService(implicit accountDao: AccountDao) {
   
     def findAll(pager: Pager[Account]): SearchResult[Account] = {
       SearchResult(pager, accountDao.countAll()) { pager =>
         accountDao.findAll(pager.allSorters, pager.limit, pager.offset)
       }
     }
   
   }

5. define template that receive a SearchResult of your entity.

   You can use @pagination to render pagination.

   @(result: SearchResult[Account])
   
   @main("Welcome to Play2 Pager") {
   
       ...snip
   
       @pagination(result, routes.Application.index)
   
   }
