Polygence Coding Challenge Solution

Project setup:

After you downloaded and extracted or cloned the project go to its folder.

Backend setup (on Windows):

cd backend

Create virtual ineviroment:

python -m -m venv "your_path_to_your_backend_folder\your_preffered_virtual_enviroment_name"

Activate your virtual enviroment:

"your_path_to_your_virtual_enviroment\Scripts\activate"

From this segment until Front end setup part you need the virtual enviroment to be activated.

Install requiered libraries:

I needed an extra library (django-cors-headers) beside Django and Django Rest Framework, because by default django does not contain Access-Control-Allow-Origin header what fetch API in javascript requeires.

pip install -r requirements.txt

Setup SQLite database:

cd spendingexercise

python manage.py migrate

Run tests:

python manage.py test

I tested some of the database field constraints with the Serializer because SQLite does not enforce it like it accepts a 15 character long string for a string field with a maximum length of 10.

Start Django developer server:

python manage.py runserver 5000

Frontend setup (on Windows):

Install requiered libraries:

At project root directory

cd web

npm install

Tests:

I did not write any Unit tests because almost all the important compoenents (FiltersAndOrderings, Form, SpendingList) somewhat dependent from the main App like useState wise. And I think if I write tests for the main App those will be called more likely integrations tests rather Unit tests.

Start React frontend:

npm start
