Connect Django Project to MongoDB Last Updated : 15 Mar, 2024 Comments Improve Suggest changes Like Article Like Report Djongo is a SQL to MongoDB query transpiler. Using djongo, we can use MongoDB as a backend database for our Django project. We don't even need to change the Django ORM. The best part is that we can setup Django with MongoDB by adding just one line of code. There is no need to change serializers, views, or any other modules. Official Docs - https://pypi.org/project/djongo/ Working - Djongo translates a SQL query string into a MongoDB query document. Therefore, there is no need to change models, serializers, views or any Django features. Django supports all django contrib libraries which make it an easy to use connector. Requirements - 1. Python 3.6 or higher. 2. MongoDB 3.4 or higher. (If you are using nested queries then MongoDB 3.6 or higher is required.) Features : Reuse Django Models/ORM - As Django Models are compatible with Djongo, we can use reuse them.Integrity checks Django allows integrity checks like missing values before they are saved to the database.For eg- Missing values are never stored if we set null=False, blank=False in EmbeddedField Validators We can apply validation checks like URLValidator, EmailValidator, RegexValidator etc. before each fields are saved to the database. Usage : Step 1: Setup Virtual Environment virtualenv myenvmyenv\Scripts\activate Step 2: Install Django pip install django Step 3: Install Djongo pip install djongo Step 4: Start Django Project django-admin startproject geeks_project Your project structure will look like this : Step 5: Make changes to settings.py file Now, open settings.py file. Comment out or remove previous SQL Database configuration and add the following code in settings.py file :settings.py DATABASES = { 'default': { 'ENGINE': 'djongo', 'NAME': 'your-database-name', } } That's it. Now you can Use MongoDB as a backend database for your django project, without changing a single django model!
