Find a Document
You can retrieve a single document from a collection by using the
FindOne() method.
Example
Tip
Read the Usage Examples to learn how to run this example.
This example uses the following Restaurant struct as a model for documents
in the restaurants collection:
type Restaurant struct { ID primitive.ObjectID `bson:"_id"` Name string RestaurantId string `bson:"restaurant_id"` Cuisine string Address interface{} Borough string Grades []interface{} }
The following example matches documents in the restaurants collection
in which the name is "Bagels N Buns", returning the first document
matched:
coll := client.Database("sample_restaurants").Collection("restaurants") filter := bson.D{{"name", "Bagels N Buns"}} var result Restaurant err = coll.FindOne(context.TODO(), filter).Decode(&result) if err != nil { if err == mongo.ErrNoDocuments { // This error means your query did not match any documents. return } panic(err) }

result variable as a Restaurant struct:
// results truncated { "ID": "5eb3d668b31de5d588f42950", "Name": "Bagels N Buns", "RestaurantId": "40363427" "Address": [...], "Borough": "Staten Island", "Cuisine": "Delicatessen", "Grades": [...] }
