MongoDB Config In Python

To connect and interact with a MongoDB database in Python, we typically use a MongoDB driver.

One of the most commonly used MongoDB drivers for Python is "pymongo".

Here's how we can configure MongoDB in Python using "pymongo":

Installation:

First, make sure we have "pymongo" installed. We can install it via "pip":

Example:

pip install pymongo

Connecting to MongoDB:

After importing "pymongo", we must provide a connection URL and database name to MongoClient.

Example:

import pymongo

# Connection URL and database name
uri = "mongodb://localhost:27017/"

# define your database name
database_name = "your_database_name"

# Connect to MongoDB server
client = pymongo.MongoClient(uri)

# Access or create a database
db = client[database_name]

# We can also explicitly access a database like this:
# db = client.your_database_name

# If authentication is required, you can provide username and password
# client = pymongo.MongoClient(uri, username="username", password="password")

Accessing Collections:

we can access MongoDB collections through instance of MongoClient by providing the database name.

Syntax:

# Accessing a collection
collection = db["your_database_name"]

# You can also explicitly access a collection like this:
# collection = db.your_database_name

Performing CRUD Operations:

Inserting documents in Collection

Syntax:

document = {"name": "Alice", "age": 30}
insert_result = collection.insert_one(document)
print("Inserted document id:", insert_result.inserted_id)

Querying documents from Collection

Syntax:

query = {"name": "Alice"}
result = collection.find_one(query)

# print the result of document if exist in database
print("Queried document:", result)

Update documents in Collection

Syntax:

query_for_search = {"name": "Alice"}
new_values = {"$set": {"age": 25}}

# update the document in database if document found
update_result = collection.update_one(query_for_search, new_values)

# print the result if document exist in database
print("Modified documents count:", update_result.modified_count)

Delete documents from Collection

Syntax:

delete_query = {"name": "Alice"}

# delete document if criteria match with record
delete_result = collection.delete_one(delete_query)

# print the count of document delete from database
print("Deleted documents count:", delete_result.deleted_count)

Closing the Connection:

Syntax:

# Close the MongoDB connection when done
client.close()

Note:

Ensure that we have a MongoDB server running locally on port 27017 (default) or adjust the connection URI accordingly to match your MongoDB server's configuration.
Additionally, replace "your_database_name" and "your_collection_name" with your actual database and collection names.
