MongoDB Manager

The MongoDBManager class is a wrapper around the pymongo package, designed to simplify the usage of MongoDB in Python applications. It provides convenient methods for connecting to a MongoDB cluster, accessing a specific database and collection, and performing common CRUD operations.

---

Installation

You can install the package using pip:

pip install mongodb_python_manager

Usage

To use the MongoDBManager class, follow these steps:

1. Import the necessary modules and classes:

from mongodb_python_manager import MongoDBManager

1. Create an instance of MongoDBManager by providing the MongoDB cluster URI, database name, and optional username and password:

mongo_db_cluster = 'your_cluster_uri'
mongodb_db_name = 'your_database_name'
mongo_db_user = 'your_username'  # Optional
mongo_db_password = 'your_password'  # Optional

mongodb_manager = MongoDBManager(
    mongo_db_cluster=mongo_db_cluster,
    mongodb_db_name=mongodb_db_name,
    mongo_db_user=mongo_db_user,
    mongo_db_password=mongo_db_password
)

1. Set the collection name you want to work with:

collection_name = 'your_collection_name'
mongodb_manager.set_collection_name(collection_name)

1. Perform database operations using the available methods:

• Insert a single document:

item = {'key1': 'value1', 'key2': 'value2'}
mongodb_manager.insert_content_in_collection(item)

• Insert multiple documents:

items = [{'key1': 'value1'}, {'key2': 'value2'}]
mongodb_manager.insert_many_content_in_collection(items)

• Update a document by ID:

item_id = 'your_item_id'
updated_item = {'key1': 'new_value1', 'key2': 'new_value2'}
mongodb_manager.update_document_in_collection(updated_item, item_id)

• Update multiple documents by ID:

items = [
    {
        'id': 'item_id1',
        'key1': 'new_value1'
    },
    {
        'id': 'item_id2',
        'key2': 'new_value2'
    }
]
mongodb_manager.update_many_documents_in_collection(items, 'id')

• Get all documents from a collection:

documents = mongodb_manager.get_all_documents_from_collection()

• Delete a document by ID:

item_id = 'your_item_id'
mongodb_manager.delete_content_in_collection(item_id)

• Delete all documents from a collection:

mongodb_manager.delete_all_documents_from_collection()

• Remember to handle exceptions appropriately and close the MongoDB connection when you're done:

mongodb_manager.client.close()

Configuration

The MongoDBManager class expects the MongoDB cluster URI, database name, and optionally, a username and password. By default, it looks for these values in environment variables named MONGO_DB_CLUSTER, MONGODB_DB_NAME, MONGO_DB_USER, and MONGO_DB_PASSWORD. Alternatively, you can provide these values directly when creating an instance of MongoDBManager.

Ensure that you have the necessary permissions and access credentials to connect to your MongoDB cluster and perform operations on the specified database and collection.

Dependencies

The MongoDBManager class relies on the following packages:

• pymongo: The MongoDB Python driver for interacting with the MongoDB server.
• python-dotenv: A package for reading configuration variables from .env files.

Example

Here's a simple example that demonstrates the usage of the MongoDBManager class:

from mongodb_manager import MongoDBManager

# Create an instance of MongoDBManager
mongo_db_cluster = 'your_cluster_uri'
mongodb_db_name = 'your_database_name'
mongo_db_user = 'your_username'  # Optional
mongo_db_password = 'your_password'  # Optional

mongodb_manager = MongoDBManager(mongo_db_cluster, mongodb_db_name, mongo_db_user, mongo_db_password)

# Set the collection name
collection_name = 'your_collection_name'
mongodb_manager.set_collection_name(collection_name)

# Insert a single document
item = {'name': 'John', 'age': 30}
mongodb_manager.insert_content_in_collection(item)

# Insert multiple documents
items = [{'name': 'Alice', 'age': 25}, {'name': 'Bob', 'age': 35}]
mongodb_manager.insert_many_content_in_collection(items)

# Update a document by ID
item_id = 'your_item_id'
updated_item = {'name': 'John Doe', 'age': 31}
mongodb_manager.update_document_in_collection(updated_item, item_id)

# Get all documents from the collection
documents = mongodb_manager.get_all_documents_from_collection()

# Print the retrieved documents
for document in documents:
    print(document)

# Delete a document by ID
item_id = 'your_item_id'
mongodb_manager.delete_content_in_collection(item_id)

# Delete all documents from the collection
mongodb_manager.delete_all_documents_from_collection()

# Close the MongoDB connection
mongodb_manager.client.close()

Make sure to replace 'your_cluster_uri', 'your_database_name', 'your_username', 'your_password', and 'your_collection_name' with your actual MongoDB cluster URI, database name, username, password, and collection name respectively.
