MongoDB PyCharm Setup & Connection Guide

In order to use MongoDB in PyCharm, you will need to install the PyMongo library. PyMongo is the official driver for interacting between Python and MongoDB database. Follow these steps to use MongoDB in PyCharm:

1. Install PyMongo library: You can install the PyMongo library by running the following command in the terminal window:

pip install pymongo

1. Importing PyMongo library: In your Python code, import the PyMongo library.

import pymongo

1. Connect to MongoDB database: Establish a MongoDB client in the code and establish a connection with the MongoDB database.

client = pymongo.MongoClient("mongodb://localhost:27017/")

Here, “mongodb://localhost:27017/” is the connection string for the MongoDB database, which can be modified based on your own configuration.

1. With databases and collections: Once connected to a database, you can select a database and retrieve a collection object to perform various operations.

db = client["mydatabase"]
collection = db["mycollection"]

1. Performing operations: You can use methods provided by the PyMongo library to execute various database operations such as inserting documents, querying documents, updating documents, and deleting documents.

# 插入文档
data = {"name": "John", "age": 30}
collection.insert_one(data)

# 查询文档
result = collection.find_one({"name": "John"})
print(result)

# 更新文档
collection.update_one({"name": "John"}, {"$set": {"age": 31}})

# 删除文档
collection.delete_one({"name": "John"})

By following the steps above, you can connect to a MongoDB database and perform various database operations in PyCharm using the PyMongo library.
