Tip
Nonexistent Databases and Collections
If the necessary database and collection don't exist when you perform a write operation, the server implicitly creates them.
coll := client.Database("sample_restaurants").Collection("restaurants")newRestaurant := Restaurant{Name: "8282", Cuisine: "Korean"}
result, err := coll.InsertOne(context.TODO(), newRestaurant)if err != nil { panic(err)}View a fully runnable example
Expected Result
After you run the full example, you can find the following inserted document in the restaurants collection:
{ "_id": ObjectId("..."), "name": "8282", "cuisine": "Korean"}For an example on how to find a document, see the Find a Document usage example.
