This is an example:
One program save data
package main
import (
"fmt"
"log"
"time"
"github.com/asdine/storm/v3"
bolt "go.etcd.io/bbolt"
)
type Record struct {
ID int `storm:"id"`
Name string `storm:"index"`
Value string
Seq int64
}
func main() {
log.SetFlags(log.LstdFlags | log.Lshortfile)
db, err := storm.Open("1.db", storm.BoltOptions(0600, &bolt.Options{Timeout: 1 * time.Second}))
if err != nil {
log.Panicln(err)
}
defer db.Close()
count := 10
tx, _ := db.From("a", "b").Begin(true)
for n := 0; n < count; n++ {
tx.Save(&Record{
ID: n + 1,
Name: fmt.Sprintf("name_%d", n+1),
Value: fmt.Sprintf("value_%d", n+1),
Seq: int64(n + 101),
})
}
tx.Commit()
var results []Record
db.From("a", "b").All(&results)
for _, v := range results {
log.Println(v)
}
var result Record
err = db.From("a", "b").One("Seq", 102, &result)
if err == nil {
log.Printf("✔️ find record: %+v", result)
} else {
log.Printf("❌ error: %s", err.Error())
}
}
another program reindex:
package main
import (
"log"
"time"
"github.com/asdine/storm/v3"
bolt "go.etcd.io/bbolt"
)
type Record struct {
ID int `storm:"id"`
Name string `storm:"index"`
Value string
Seq int64 `storm:"index"`
}
func main() {
log.SetFlags(log.LstdFlags | log.Lshortfile)
db, err := storm.Open("1.db", storm.BoltOptions(0600, &bolt.Options{Timeout: 1 * time.Second}))
if err != nil {
log.Panicln(err)
}
defer db.Close()
//ReIndex return error bucket not found
log.Println(db.From("a", "b").ReIndex(&Record{}))
var results []Record
db.From("a", "b").All(&results)
for _, v := range results {
log.Println(v)
}
var result Record
err = db.From("a", "b").One("Seq", 102, &result)
if err == nil {
log.Printf("✔️ find record: %+v", result)
} else {
log.Printf("❌ error: %s", err.Error())
}
}
