Help with func(*iter)For

[Greg Worley]

Trying to use func(*iter)For and implement the example from the docs.

package main

import (

        "fmt"

        "launchpad.net/mgo"

        "launchpad.net/gobson/bson"

)

type Person struct {

        Name  string

        Phone string

}

func main() {

        session, err := mgo.Mongo("mongotest")

        if err != nil {

                panic(err)

        }

        defer session.Close()

        session.SetMode(mgo.Monotonic, true)

        c := session.DB("test").C("people")

        err = c.Insert(&Person{"Ale", "+55 53 8116 9639"},

                &Person{"Cla", "+55 53 8402 8510"})

        if err != nil {

                panic(err)

        }

                iter, err := c.Find(bson.M{}).iter()

                if err != nil {

                panic(err)

        }

        var result *Person

        err := iter.For(&result, func() os.Error {

                fmt.Println(result.Name)

                return nil

        })

        if err != nil {

                panic(err)

        }

}

seems iter, err := c.Find(bson.M{}).iter()

gives me iter as a query type, and not type iter.

Hey Greg,

Find will give you a Query value:

http://goneat.org/lp/mgo#Collection.Find

Iter will give you an Iter value:

http://goneat.org/lp/mgo#Query.Iter

Both Query and Iter support For:
