Introduction

Implementation of flask and pymongo using mflix sample data set and mflix python UI

This is a short guide on how to integrated MongoDB Atlas to Flask applications using Flask-PyMongo wrapper and pymongo driver.

Project Structure

The mflix directory holds the application logic.

db.py Where all database CRUD patterns are exposed as functions.
api/movies.py Where the web api is exposed to the UI

The main directory holds the following files:

run.py Where the Flask application is initialize and the config is loaded
sample_ini Where the connection URI to MongoDB Atlas is configured
requirments.txt Where the dependencies this project needs to run are located.

How to set-up

Clone the repository.

git clone git@github.com:mongodb-developer/flask-pymongo-example.git

Start a python virtual env:

# navigate to the flask-pymongo-example directory
cd flask-pymongo-example

# create the virtual environment for MFlix
python3 -m venv mflix-venv

# activate the virtual environment
source mflix_venv/bin/activate

Install dependencies

python3 -m pip install -r requirments.txt

Rename the sample_ini to .ini.

Get your Atlas cluster with sample data set connection string and place in DB_URI parameter under .ini

Make sure you have IP in the Atlas access list and username/password of your Atlas user correctly specified.

Start the application

python ./run.py
