muscles-data-mongodb 0.1.1

MongoDB DocumentStorePort adapter for muscles-data

muscles-data-mongodb

MongoDB adapter package for muscles-data.

This package is intentionally separate from muscles-data: the core package owns typed ports and runtime, while this package owns the PyMongo-backed DocumentStorePort adapter.

Install

python -m pip install muscles-data-mongodb

For local framework development:

PYTHONPATH=../muscles-data/src:src python3 -m pytest -q

Configuration

data:
  resources:
    mongo.content:
      type: mongodb
      url: ${MONGO_URL}
      database: content
      timeout: 3
      max_limit: 100

Usage

Register the external factory in the project composition root:

from muscles_data.catalog import DataAdapterCatalog
from muscles_data.config import DataConfig
from muscles_data.ports import DocumentStorePort
from muscles_data.runtime import DataRuntime
from muscles_data_mongodb import MongoDocumentStoreFactory

catalog = DataAdapterCatalog.with_defaults()
catalog.register(MongoDocumentStoreFactory())

runtime = DataRuntime(config=DataConfig.from_raw(config), catalog=catalog)
store = runtime.require_port("mongo.content", DocumentStorePort)

Then use the narrow port:

store.upsert_document("profiles", "denis", {"name": "Denis"})
document = store.get_document("profiles", "denis")
documents = store.find_documents("profiles", filters={"role": "developer"}, limit=20)
store.delete_document("profiles", "denis")

The adapter maps document_id to MongoDB _id internally and returns public documents without _id to keep the port backend-neutral.

Capabilities

MongoDocumentStoreFactory provides:

• document_store;
• healthcheck;
• native_client only when the resource declares native_client: true.

Native access is an advanced project escape hatch:

from muscles_data import DataCapability

client = runtime.require_resource("mongo.content", DataCapability.NATIVE_CLIENT).native_client()

Use the native client for backend-specific aggregations, indexes or operations that do not belong in DocumentStorePort.

Boundaries

This package owns:

• lazy PyMongo client creation;
• database binding;
• simple document get/find/upsert/delete;
• safe inspect() and doctor();
• bounded find_documents() limits.

It does not own:

• ORM/document model layers;
• schema validation;
• migrations;
• complex aggregation abstraction;
• business repository APIs.

data.doctor performs a MongoDB ping. data.resources.list and package initialization do not open a MongoDB connection.
