    <p>I've written a simple MongoDB package with some CRUD methods:</p> <pre><code>package backend import "labix.org/v2/mgo" type MongoDBConn struct { session *mgo.Session } type ToDo struct { Title string Description string } func NewMongoDBConn() *MongoDBConn { return &amp;MongoDBConn{} } func (m *MongoDBConn) Connect(url string) *mgo.Session { session, err := mgo.Dial(url) if err != nil { panic(err) } m.session = session return m.session } func (m *MongoDBConn) Stop() { m.session.Close() } func (m *MongoDBConn) AddToDo(title, description string) (err error) { c := m.session.DB("test").C("people") err = c.Insert(&amp;ToDo{title, description}) if err != nil { panic(err) } return nil } </code></pre> <p>I have a server.go where I create a Http Server and have handlers for the different URLs. I'd like to be able to connect to MongoDB and call the AddToDo method within a specific handler. I can connect to the DB from the main method of my server:</p> <pre><code>import ( "./backend" //other boilerplate imports ) func AddHandler(writer http.ResponseWriter, request *http.Request) { log.Printf("serving %v %v", request.Method, request.URL.Path[1:]) if request.Method != "POST" { serve404(writer) return } title := request.FormValue("title") description := request.FormValue("description") fmt.Fprintf(writer, " title description %v %v", title, description) //I can't call mongoConn.AddToDo(title, description) from here } func main() { //connect to mongoDB mongoConn := backend.NewMongoDBConn() _ = mongoConn.Connect("localhost") defer mongoConn.Stop() } </code></pre> <p>But I'm not sure how to call mongoConn.AddToDo(title, description string) method from the handler. Should I create a global db connection variable?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
