Find and update a document

Finds a single document in a collection using filter and sort clauses, and then updates properties in that document. Optionally, if no document matches the filter, inserts a new document.

This method and the method to update a document have the same database effect but differ in their return value. This method returns the document that was found and updated. The method to update a document returns details about the success of the update.

Result

  • Python

  • TypeScript

  • Java

  • curl

Updates a document that matches the specified parameters, and returns a dictionary representation of the document. If no document was found, returns None.

The method parameters control whether the returned document reflects the original or updated values.

The fields included in the returned document depend on the projection specified in the method.

If an upsert is requested, the method inserts a new document if no document matches the filter.

Example response:

{'_id': 101, 'name': 'John Doe'}

Updates a document that matches the specified parameters, and returns a promise that resolves to the document. If no document was found, returns returns a promise that resolves to null.

The method parameters control whether the returned document reflects the original or updated values.

The fields included in the returned document depend on the projection specified in the method.

If an upsert is requested, the method inserts a new document if no document matches the filter.

Example resolved response:

{_id: 101, name: 'John Doe'}

Updates a document that matches the specified parameters, and returns the document (Optional<T>). If no document was found, returns returns Optional.empty().

The method parameters control whether the returned document reflects the original or updated values.

The fields included in the returned document depend on the projection specified in the method.

If an upsert is requested, the method inserts a new document if no document matches the filter.

Updates a document that matches the specified parameters, and returns a dictionary representation of the document. If no document was found, returns null instead of a dictionary representation of the document.

The method parameters control whether the returned document reflects the original or updated values.

The fields included in the returned document depend on the projection specified in the method.

The response also includes details about the success of the operation, such as the number of documents that were modified.

If an upsert is requested, the method inserts a new document if no document matches the filter.

Example response:

{
  "data": {
    "document": {
      "_id":"101",
      "name":"John Doe"
    }
  },
  "status":{
    "matchedCount":1,
    "modifiedCount":1
  }
}

Example response if no document was found:

{
  "data":{
    "document":null
  },
  "status":{
    "matchedCount":0,
    "modifiedCount":0
  }
}

Example response if a new document was inserted:

{
  "data":{
    "document":null
  },
  "status":{
    "upsertedId":"7d690267-28f5-47e8-a902-6728f587e84e",

sort

Dict[str, Any]

Optional. Sorts documents by one or more fields, or performs a vector search.

For more information, see Sort clauses for collections.

Sort clauses can use only indexed fields. If you apply selective indexing when you create a collection, you can’t reference non-indexed fields in sort queries.

int

Optional. An alias for general_method_timeout_ms. Since this method issues a single HTTP request, general_method_timeout_ms and request_timeout_ms are equivalent.

timeout_ms

int

Optional. An alias for general_method_timeout_ms.

boolean

Optional. Whether to insert a new document if no document matches the filter criteria.

Default: False

projection

Projection

Optional. Controls which fields are included or excluded in the returned document.

For more information, see Projections for collections.

sort

Sort

Optional. Sorts documents by one or more fields, or performs a vector search.

boolean

Whether to include details about the success of the operation in the response.

Default: False

timeout

number | TimeoutDescriptor

Optional.

The timeout(s) to apply to this method. You can specify requestTimeoutMs and generalMethodTimeoutMs. Since this method issues a single HTTP request, these timeouts are equivalent.

Details about the timeout parameter

The TimeoutDescriptor object can contain these properties:

Update a document that is most similar to a search string

To find the document whose $vector value is most similar to the $vector value of a given search string, use a sort with the search string that you want to vectorize and match. For more information, see Find data with vector search.

Vector search with vectorize is only available for collections that have vectorize enabled. For more information, see $vector and $vectorize in collections.

Update a document after applying a non-vector sort

You can use a sort clause to sort documents by one or more fields.

For more information, see Sort clauses for collections.

Sort clauses can use only indexed fields. If you apply selective indexing when you create a collection, you can’t reference non-indexed fields in sort queries.

To update a nested property, use dot notation. For example, field.subfield.subsubfield.

To update an item in a list, specify a numeric index. For example, listProperty.3.

Insert a new document if no matching document exists

You can use upsert to insert a new document if no document matches the filter criteria.

  • Python

  • TypeScript

  • Java

  • curl

from astrapy import DataAPIClient

# Get an existing collection
client = DataAPIClient("ASTRA_DB_APPLICATION_TOKEN")
database = client.get_database("ASTRA_DB_API_ENDPOINT")
collection = database.get_collection("COLLECTION_NAME")

# Update a document
result = collection.find_one_and_update(
    {
        "$and": [
            {"isCheckedOut": False},
            {"numberOfPages": {"$lt": 300}},
        ]
    },
    {"$set": {"color": "blue"}},
    upsert=True,
)

print(result)

You can also use the setOnInsert operator specify additional fields to set if a new document is created:

from astrapy import DataAPIClient

# Get an existing collection
client = DataAPIClient("ASTRA_DB_APPLICATION_TOKEN")
database = client.get_database("ASTRA_DB_API_ENDPOINT")

      "$set": {"color": "blue"},
