In MongoDB doing something like db.mycollection.find() returns all documents in a collection.

When working in GoLang using the package and I do for example:

query := db.C("client").Find();

It complains that it requires input in the form of an interface. All I need to do is retrieve all documents and iterate through them and display each one for now. How do I achieve this effect? All examples I have seen seem to have filters in place.

    Found a solution:

        var results []client
        err := db.C("client").Find(nil).All(&results)
        if err != nil {
            // TODO: Do something about the error
        } else {
            fmt.Println("Results All: ", results)

    func (uc UserController) GetUsersList(w http.ResponseWriter,r *http.Request,p httprouter.Params){
    var u []models.User
    // Fetch user
    if err := uc.session.DB("mydb").C("users").Find(nil).All(&u); err != nil {
        fmt.Println("Results All: ", u) 
    uj, _ := json.Marshal(u)
    w.Header().Set("Content-Type", "application/json")
    fmt.Fprintf(w, "%s", uj)
