In this case, you will have to ensure that each operation ID is **unique** in some other way.

For example, you could make sure that each *path operation* has a tag, and then generate the operation ID based on the **tag** and the *path operation* **name** (the function name).

### Custom Generate Unique ID Function { #custom-generate-unique-id-function }

            String nonceStr = Arrays.toString(nonce);
            assertFalse(nonces.contains(nonceStr), "Nonce should be unique");
            nonces.add(nonceStr);
        }

        // Then all nonces should be unique
        assertEquals(numNonces, nonces.size(), "All nonces should be unique");
    }

    @Test
    @DisplayName("Should generate secure nonces with proper randomness")

And Python has a special data type for sets of unique items, the `set`.

Then we can declare `tags` as a set of strings:

{* ../../docs_src/body_nested_models/tutorial003_py310.py hl[12] *}

With this, even if you receive a request with duplicate data, it will be converted to a set of unique items.

* Data validation.
* Automatic annotation and documentation.

## Other data types { #other-data-types }

Here are some of the additional data types you can use:

* `UUID`:
    * A standard "Universally Unique Identifier", common as an ID in many databases and systems.
    * In requests and responses will be represented as a `str`.
* `datetime.datetime`:
    * A Python `datetime.datetime`.

        this.keyStore = keyStore;
        this.keyStorePassword = keyStorePassword != null ? keyStorePassword.clone() : null;
    }

    /**
     * Store a session key
     *
     * @param sessionId unique session identifier
     * @param key the secret key to store
     * @param algorithm the key algorithm (e.g., "AES")
     */
    public void storeSessionKey(String sessionId, byte[] key, String algorithm) {

If you are not an "expert" in OpenAPI, you probably don't need this.

///

You can set the OpenAPI `operationId` to be used in your *path operation* with the parameter `operation_id`.

You would have to make sure that it is unique for each operation.

{* ../../docs_src/path_operation_advanced_configuration/tutorial001.py hl[6] *}

### Using the *path operation function* name as the operationId { #using-the-path-operation-function-name-as-the-operationid }

        this.keyManager = keyManager;
        this.sessionKey = sessionKey != null ? sessionKey.clone() : null;
        this.preauthIntegrityHash = preauthHash != null ? preauthHash.clone() : null;

        // Generate unique session ID for key management
        this.sessionId = String.format("smb-enc-%d-%d", System.currentTimeMillis(), secureRandom.nextLong());

        if (keyManager != null) {
            // Store keys securely

		ChecksumType: userDefined[hash.MinIOMultipartChecksumType],
	}, nil
}

// NewMultipartUpload - initialize a new multipart upload, returns a

        // Create rules with unique IDs
