Insert a Document

You can insert a document into a collection by using the InsertOne() 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 {
	Name         string
	RestaurantId string        `bson:"restaurant_id,omitempty"`
	Cuisine      string        `bson:"cuisine,omitempty"`
	Address      interface{}   `bson:"address,omitempty"`
	Borough      string        `bson:"borough,omitempty"`
	Grades       []interface{} `bson:"grades,omitempty"`
}

The omitempty struct tag omits the corresponding field from the inserted document when left empty.

The following example inserts a new document to the restaurants collection:

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)
}

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.
