I'm currently using a mongodb with mgo lib for a web application, but I'm not sure if the way I'm using it, is good one ..
package db
import (
"gopkg.in/mgo.v2"
)
const (
MongoServerAddr = "192.168.0.104"
RedisServerAddr = "192.168.0.104"
)
var (
MongoSession, err = mgo.Dial(MongoServerAddr)
MDB = MongoSession.DB("message")
MCol = MDB.C("new")
MSav = MDB.C("save")
UDB = MongoSession.DB("account")
UCol = UDB.C("user")
)
I init the db session and create variables who takes the collection and document value,
so when I need to query a collection, I use the variable to make it.
Like that :
func UserExist(username string) bool {
user := Users{}
err := db.UCol.Find(bson.M{"username": username}).One(&user)
if err != nil {
return false
} else {
return true
}
}
So is there a best practice or this one is fine ..?
Thanks
