Find and delete a document

Finds a single document in a collection using filter and sort clauses, and then deletes that document.

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

Result

Python
TypeScript
Java
curl

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

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

Example response:

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

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

Example resolved response:

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

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

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

Deletes 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 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 deleted.

Example response:

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

Example response if no document was found:

{
  "data":{
    "document":null
  },
  "status":{
    "deletedCount": 0
  }
}

Parameters

Python

curl

Use the find_one_and_delete method, which belongs to the astrapy.Collection class.

Method signature

find_one_and_delete(
  filter: Dict[str, Any],
  *,
  projection: Dict[str, bool],
  sort: Dict[str, Any],
  general_method_timeout_ms: int,
  request_timeout_ms: int,
  timeout_ms: int,
) -> Dict[str, Any]

Name Type Summary

Name	Type	Summary
`filter`	`Dict[str, Any]`	Optional. An object that defines filter criteria using the Data API filter syntax. The method only finds documents that match this filter criteria. For a list of available filter operators and more examples, see Filter operators for collections. Filters can use only indexed fields. If you apply selective indexing when you create a collection, you can’t reference non-indexed fields in a filter.
`projection`	`Dict[str, bool]`	Optional. Controls which fields are included or excluded in the returned document. For more information, see Projections for collections. Default: The default projection for the collection. Certain fields, like `$vector` and `$vectorize`, are excluded by default. Certain fields, like `_id`, are included by default.
`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. For vector searches, this parameter can use either `$vector` or `$vectorize`.
`general_method_timeout_ms`	`int`	Optional. The maximum time, in milliseconds, that the client should wait for the underlying HTTP request. Default: The default value for the collection. This default is 30 seconds unless you specified a different default when you initialized the `Collection` or `DataAPIClient` object. For more information, see Timeout options.
`request_timeout_ms`	`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`.

Delete a document that is most similar to a search vector

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

Delete 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.

Delete a document after applying a non-vector sort

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.

Include only specific fields in the response

Certain fields, like $vector and $vectorize, are excluded by default and will only be returned if you specify them in the projection. Certain fields, like _id, are included by default.
