## Import Pydantic's `BaseModel` { #import-pydantics-basemodel }

First, you need to import `BaseModel` from `pydantic`:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## Create your data model { #create-your-data-model }

Then you declare your data model as a class that inherits from `BaseModel`.

Use standard Python types for all the attributes:

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}

	bucket := "minio-bucket"
	object := "minio-object"

	// Create bucket.
	err := obj.MakeBucket(context.Background(), bucket, MakeBucketOptions{})
	if err != nil {
		// Failed to create newbucket, abort.
		t.Fatalf("%s : %s", instanceType, err.Error())
	}
	opts := ObjectOptions{}
	// Initiate Multipart Upload on the above created bucket.
	res, err := obj.NewMultipartUpload(context.Background(), bucket, object, opts)

val=$(./mc tag list minio1/newbucket --json | jq -r .tagset | jq -r .key)
if [ "${val}" != "val2" ]; then
	echo "expected bucket tag to have replicated, exiting..."
	exit_1
fi

# Test if bucket created/deleted when minio1 is down healed
diff -q <(./mc ls minio1) <(./mc ls minio2) 1>/dev/null
if [ $? -ne 0 ]; then
	echo "expected 'bucket2' delete and 'newbucket2' creation to have replicated, exiting..."
	exit_1
fi

		if err != nil {
			t.Fatalf("Test %d : MinIO %s: Failed parsing response body: <ERROR> %v", i, instanceType, err)
		}

		// Verify whether the bucket obtained object is same as the one created.
		if testCase.expectedContent != nil && !bytes.Equal(testCase.expectedContent, actualContent) {
			t.Log(string(testCase.expectedContent), string(actualContent))

* There are 4 minio distributed instances created by default. You can add more MinIO services (up to total 16) to your MinIO Compose deployment. To add a service
  * Replicate a service definition and change the name of the new service appropriately.

#
# Source files generated by annotation processors appear directly
# under the root of srcjars jars created by bazel, rather than under
# the maven-style src/main/java subdirectory.
#
# Bazel manages annotation generated source as follows: First, it
# calls javac with options that create generated files under a
# bazel-out directory. Next, it archives the generated source files

## Use `SecurityScopes` { #use-securityscopes }

Now update the dependency `get_current_user`.

This is the one used by the dependencies above.

Here's where we are using the same OAuth2 scheme we created before, declaring it as a dependency: `oauth2_scheme`.

val=$(./mc tag list minio1/newbucket --json | jq -r .tagset | jq -r .key)
if [ "${val}" != "val2" ]; then
	echo "expected bucket tag to have replicated, exiting..."
	exit_1
fi

# Test if bucket created/deleted when minio1 is down healed
diff -q <(./mc ls minio1) <(./mc ls minio2) 1>/dev/null
if [ $? -ne 0 ]; then
	echo "expected 'bucket2' delete and 'newbucket2' creation to have replicated, exiting..."
	exit_1
fi

### Create the **FastAPI** Code { #create-the-fastapi-code }

* Create an `app` directory and enter it.
* Create an empty file `__init__.py`.
* Create a `main.py` file with:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()

        run: |
          container_name=$(docker ps --filter "ancestor=opengauss/opengauss:7.0.0-RC1.B023" --format "{{.Names}}")
          if [ -z "$container_name" ]; then
            echo "Error: failed to find a container created from the 'opengauss/opengauss:7.0.0-RC1.B023' image."
            exit 1
          fi
          max_retries=12
          retry_count=0
          if [ -t 0 ]; then
