Bongo Pagination

#go #mongodb

In our previous article, we made a collection with bongo.

If you haven't read it, you can look here Make the collection find using Go bongo

Now we will paginate our query.

we continue the connection in the same way

Perpage 20
Active Page 1

package main

import (
  "log"

  "github.com/globalsign/mgo/bson"
  "github.com/go-bongo/bongo"
)

type User struct {
  bongo.DocumentBase `bson:",inline"`
  Username          string
}


func main() {

  // Bongo Connection Config
  config := &bongo.Config{
    ConnectionString: "localhost",
    Database:         "test",
  }

  connection, err := bongo.Connect(config)

  if err != nil {
    log.Fatal(err)
  }

  result := connection.Collection("users").Find(bson.M{})

  // Perpage = 20, activePage = 1
  info, _ := result.Paginate(20, 1)

  users := make([]User, info.RecordsOnPage)

  for i := 0; i < info.RecordsOnPage; i++ {
    _ = result.Next(&users[i])
  }


  log.Println(users)
}
