banking's Introduction

Banking

This repo contain a small and simple approach to a initial banking solution.

This repo depends on the following:

Poetry dependency manager
Python 3.9 brew install python

To Run it locally:

Setup instructions

After getting poetry installed you should create a virtual environment and activate it $ python3 -m venv env $ source env/bin/activate Then install dependencies using poetry: $ poetry install

Run instructions

To execute the solution you have to provide a valid postgres connection: $ DATABASE_URL="postgresql://user:password@localhost:5432/database" $ uvicorn src.main:app --reload After that you would be able to see following output:

INFO:     Started server process [35568]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

A mock data was created and pre-inserted using a proper orm mapper. Needed person data pre inserted can be viewed at `http://127.0.0.1:8000/docs#/people/get_people_people__get`

/openapi.json especification is at http://127.0.0.1:8000/docs

Running using Dockerfile:

Execute following commands:

cd ~/banking
docker build -t banking
docker run -p 80:80 -e DB_URL=postgresql://user:pw@host:5432/db banking

Now you can access docs at

To run tests you need to execute:

pytest tests/routes/transaction.py
pytest tests/routes/account.py

Considerations:

A basic layered design patter was used to keep dependency only for inner layer
A much better approach would be use a complex messaging/events architecture as described here or at cosmic python.
It's simple test relates a admin view where user who is getting and inserting data at resources has access to all data. Otherwise will be a huge security issue an user accessing other's data.
I've used simple postgres dockerfile to support application. You can also ask me for already provisioned db url's.
