Connect MongoDB with Django project using PyMongo

In this article, we will discuss how to connect MongoDB with a Django project using PyMongo and cover the complete guide to MongoDB CRUD operations.

Step 1: Install PyMongo

To connect MongoDB with a Django project, you first need to install PyMongo, which is a Python package that allows you to interact with the MongoDB database. You can install PyMongo using pip:

            pip install pymongo
        

Step 2: Configure MongoDB in Django settings

Once PyMongo is installed, you need to configure the MongoDB connection in your Django project settings. You can do this by adding the following configuration in your settings.py file:

            import pymongo

            DATABASES = {
                'default': {
                    'ENGINE': 'djongo',
                    'NAME': 'your_database_name',
                    'CLIENT': {
                        'host': 'your_mongodb_host',
                        'port': 27017,
                        'username': 'your_mongodb_username',
                        'password': 'your_mongodb_password',
                    }
                }
            }
        

Step 3: Connect to MongoDB and Perform CRUD Operations

Now that you have set up the MongoDB connection in your Django project, you can use PyMongo to connect to the MongoDB database and perform CRUD (Create, Read, Update, Delete) operations. Here is an example of how you can connect to the MongoDB database and perform CRUD operations using PyMongo:

            import pymongo

            # Connect to MongoDB
            client = pymongo.MongoClient("your_mongodb_connection_string")
            db = client["your_database_name"]
            collection = db["your_collection_name"]

            # Create
            data = {"name": "John", "age": 25}
            collection.insert_one(data)

            # Read
            query = {"name": "John"}
            result = collection.find_one(query)
            print(result)

            # Update
            update_query = {"name": "John"}
            new_values = {"$set": {"age": 30}}
            collection.update_one(update_query, new_values)

            # Delete
            delete_query = {"name": "John"}
            collection.delete_one(delete_query)
        

Conclusion

By following the above steps, you can easily connect MongoDB with a Django project using PyMongo and perform CRUD operations. This allows you to leverage the power of MongoDB in your Django applications and build scalable and robust solutions.
