Present me some Python code

Beneath is an instance of the way you may implement a fundamental subscription circulation utilizing Stripe in a Django mission. This instance focuses on the backend code and assumes you’ve arrange the required templates, views, and fashions by yourself.

Be sure to put in the stripe library utilizing pip set up stripe and configure your Stripe API keys in your Django settings earlier than continuing.

import stripe
from django.conf import settings
from django.contrib.auth.decorators import login_required
from django.shortcuts import render, redirect
from django.urls import reverse
from .fashions import Subscription

stripe.api_key = settings.STRIPE_SECRET_KEY

@login_required
def subscription_plans(request):
    # Fetch out there subscription plans from Stripe
    plans = stripe.Plan.listing()
    return render(request, 'subscriptions/subscription_plans.html', {'plans': plans})

@login_required
def create_subscription(request, plan_id):
    consumer = request.consumer
    plan = stripe.Plan.retrieve(plan_id)

    # Create a subscription on Stripe
    subscription = stripe.Subscription.create(
        buyer=consumer.stripe_customer_id,  # Assuming you retailer buyer IDs
        objects=[{'plan': plan.id}],
        payment_behavior='default_incomplete',  # Change primarily based in your necessities
        broaden=['latest_invoice.payment_intent']
    )

    # Save subscription particulars to your database
    Subscription.objects.create(
        consumer=consumer,
        subscription_id=subscription.id,
        plan_id=plan.id,
        standing=subscription.standing,
        current_period_start=subscription.current_period_start,
        current_period_end=subscription.current_period_end
    )

    return redirect(reverse('subscription_success'))

# webhook_handlers.py
from django.http import HttpResponse
import json
import stripe
from django.conf import settings

stripe.api_key = settings.STRIPE_SECRET_KEY

def handle_subscription_webhook(request):
    payload = request.physique
    occasion = None

    attempt:
        occasion = stripe.Occasion.construct_from(
            json.hundreds(payload), stripe.api_key
        )
    besides ValueError as e:
        # Invalid payload
        return HttpResponse(standing=400)

    # Deal with particular occasions
    if occasion.sort == 'bill.payment_failed':
        # Deal with cost failure
        # Replace consumer's subscription standing or take essential actions

    return HttpResponse(standing=200)

Please be aware that this can be a simplified instance. In a real-world state of affairs, you’d have to deal with error instances, add correct consumer authentication, implement webhook safety, deal with cost affirmation, and combine this together with your templates and frontend parts.
