How To use the application:

• go to the project's root directory (where the manage.py file is)
• pip install -r requirements.txt
• python manage.py makemigrations
• python manage.py migrate
• python manage.py runserver

Example requests to all endpoints (and all request methods) were performed in postman and file postman.json can be

imported in postman to test them.

Filtering list of products is done by adding ?attribute=value and ordering is done by adding ?ordering=attribute

for ascending ordering or ?ordering=-attribute for descending ordering

Application uses BasicAuth so the Authorization header requires a value "Basic value" where the value is the encoded

username and password

Postman can handle the conversion for us and you can just provide username and password

To add a product, instead of using json format as in all other endpoints, i used form-data to pass in a picture directly.

There is an example in the postman.json file

Endpoints and possible methods:

• /statistics ['GET'] - get a list of top-selling products
• /products/ ['GET','POST'] - get a list of all products or add a new product
• /productCategories/ ['GET','POST'] - get a list of all categories or add a new category
• /orders/ ['GET','POST'] - get a list of all orders or add a new order
• /products/str:pk ['GET','PUT','DELETE'] - get, edit, or delete product with passed id
• /productCategories/str:pk ['GET','PUT','DELETE'] - get, edit, or delete category with passed id
• /orders/int:pk ['GET','PUT','DELETE'] - get, edit, or delete order with passed id

Users as well as sellers are predefined by the super user (created with python manage.py createsuperuser)

and can be created through the admin panel (localhost:8000/admin)

Normal users have role=user and sellers have role=seller

Anyone can perform GET request, only sellers can perform all PUT, DELETE and POST requests (except for ordering),

and users can perform orders POST request.

#Accounts i used to test (username, password):

admin, admin - superuser without role

user, user - user with the role of user

seller, seller - user with the role of seller

Django Rest Framework provides a basic preview of API data when visiting the link from a web browser. Also,

when creating a request without any data, the response tells what data was not provided in the request body.
