Flask REST API record sender's IP address - rest

Question

I have created a minimal REST API using Flask, SQLAlchemy, and Marshmallow. here is app.py file:
from flask import Flask, request, jsonify
from flask_sqlalchemy import SQLAlchemy
from flask_marshmallow import Marshmallow
import os
# Initialize App
app = Flask(__name__)
basedir = os.path.abspath(os.path.dirname(__file__))
# Database Setup
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'db.sqlite')
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
# Init db
db = SQLAlchemy(app)
# Init marshmallow
ma = Marshmallow(app)
# Product Class/Model
class Product(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(100), unique=True)
description = db.Column(db.String(200))
price = db.Column(db.Float)
qty = db.Column(db.Integer)
def __init__(self, name, description, price, qty):
self.name = name
self.description = description
self.price = price
self.qty = qty
# Product Schema
class ProductSchema(ma.Schema):
class Meta:
fields = ('id', 'name', 'description', 'price', 'qty')
# Init Schema
product_schema = ProductSchema()
products_schema = ProductSchema(many=True)
# Create Product
#app.route('/product', methods=['POST'])
def add_product():
name = request.json['name']
description = request.json['description']
price = request.json['price']
qty = request.json['qty']
new_product = Product(name, description, price, qty)
db.session.add(new_product)
db.session.commit()
return product_schema.jsonify(new_product)
# Get All Products
#app.route('/receive', methods=['GET'])
def get_products():
all_products = Product.query.all()
result = products_schema.dump(all_products)
return jsonify(result)
# Run the Server
if __name__ == '__main__':
app.run(debug=True)
I want to extract the sender's IP address through the GET method. However, the sender's IP doesn't need to be part of the JSON payload.
Example: POST
{
"name": "Product 1",
"description": "This is product 1",
"price": 120.00,
"qty": 100
}
GET
{
"ip": "<whatever-the-ip>"
"name": "Product 1",
"description": "This is product 1",
"price": 120.00,
"qty": 100
}
How do I implement this functionality in my code? I tried using request.remote_addr, but I am not getting what I expected.

You can modify the response in the GET route any way you want before returning it, I added the request's IP to the response after serializing the db result like this:
# Get All Products
#app.route('/receive', methods=['GET'])
def get_products():
all_products = Product.query.all()
results = products_schema.dump(all_products)
for product in results
product.update({"ip": str(request.remote_addr)})
return jsonify(results)
