In MongoDB doing something like db.mycollection.find() returns all documents in a collection.
When working in GoLang using the package labix.org/v2/mgo 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 {
w.WriteHeader(404)
fmt.Println("Results All: ", u)
return
}
uj, _ := json.Marshal(u)
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(200)
fmt.Fprintf(w, "%s", uj)
}
