How to insert multiple values of nested struct in mongodb with go -

i trying insert multiple values nested struct in mongodb golang ...

{  "_id" : objectid("56b879528d04effa4ae2de2c"),     "task_content" : "some text",    "priority" : "2",     "deadline" : {        "start_time" : isodate("2009-04-04t00:00:00z"),        "end_time" : isodate("2009-05-04t00:00:00z")     },    "users" : {       "u_status" : "completed",       "u_name" : john_smith,       "u_status" : "completed",       "u_name" : harry_potter    },  } 

is possible in mongo. i.e. there same name of keys values different.. here sample code tried

type deadline struct {     start_time  time.time `bson:"start_time"`     end_time    time.time `bson:"end_time"`   }   type users struct {     status  string `bson:"u_status"`     user_name  string `bson:"u_name"`   }   type taskdata struct {     id bson.objectid  `bson:"_id"`     task_content string  `bson:"task_content"`     priority string  `bson:"priority"`     deadline     users     []users    }  func tasktodo(w http.responsewriter, r *http.request) {     var doc taskdata     retmap := make(map[string]map[string]string)     retmap["user"]["1"] = "john_smith"     retmap["user"]["2"] = "harry_potter"      stime, _ := time.parse("2006/01/02","2009-04-04")     etime, _ := time.parse("2006/01/02","2009-05-04")       doc = taskdata{id: bson.newobjectid(),       task_content:"some text", priority:"2",       deadline:deadline{         start_time:stime,         end_time:etime,       }}      := 1; <= len(retmap["user"]);i++ {       doc.users = append(doc.users, users{         user_name : retmap["user"][strconv.itoa(i)],         status : "completed",        })     }     fmt.println(doc)     err := collection.insert(doc)     if err != nil {       fmt.printf("can't insert document: %v\n", err)       fmt.fprintf(w,"%s","can't insert document:%v\n", err)       os.exit(1)       }else{         fmt.println("task inserted ... ")       } } 

ignore basic mistakes in sample code. kindly me in advance

you need export sub structs make work.

like this:

type deadline struct {     start_time  time.time `bson:"start_time"`     end_time    time.time `bson:"end_time"` } type users struct {     status  string `bson:"u_status"`     user_name  string `bson:"u_name"` } type taskdata struct {     id bson.objectid  `bson:"_id"`     task_content string  `bson:"task_content"`     priority string  `bson:"priority"`     deadline deadline `bson:"deadline"`     users     []users `bson:"users"` }
