Affiliate system for django

Affiliate system to reward partners with their visitors payments. Contains abstract models with basic functionality, so it is easy to subclass them and add your custom logic and relations.

Note: version 0.2.0 is backwards incompatible with previous versions.

Example

Visitor goes to site with affiliate code:

http://site.com/?aid=12345

This code is saved in his cookies (also another way is supported: keep aid=12345 at every url). Now each request object has property request.affiliate, so you can access to affiliate, that attract current visitor, and therefore reward him at needed event.

Property request.affiliate is lazy. To check, that affiliate exist, do this:

    if request.affiliate.exists():
        # optionally check, that he is active:
        if request.affiliate.is_active:
            # request comes from affiliate with code 
            # affiliate.aid

You can find example project in this repository.

Used by projects

Requirements

• python (2.7, 3.7)
• django (1.10, 1.11)

Quick start

1. Install this package to your python distribution

    pip install django-affiliate
   

2. Add 'affiliate' to INSTALLED_APP:

    INSTALLED_APPS = [
        # ...
        'affiliate',
    ]
   

3. Add 'affiliate.middleware.AffiliateMiddleware' to MIDDLEWARE_CLASSES:

    MIDDLEWARE = [
        # ...
        'affiliate.middleware.AffiliateMiddleware',
    ]
   

4. Define your custom affiliate model (similar to custom user model):

    # our_app/models.py
    from django.db import models
    from affiliate.models import AbstractAffiliate
   
   
    class Affiliate(AbstractAffiliate):
        pass  # or add some your custom fields here
   
    # settngs.py
    AFFILIATE_AFFILIATE_MODEL = 'our_app.Affiliate'
   

5. Create tables

    # django >= 1.7
    python manage.py makemigrations our_app
    python manage.py migrate our_app
   

6. Finally, reward affiliate

    from django.views.generic import FormView
    from affiliate.tools import get_affiliate_model
   
    Affiliate = get_affiliate_model()
   
    class SomeView(FormView):
        # ...
   
        def form_valid(self.form):
            product = self.get_product()
            if self.request.affiliate.exists() and self.request.affiliate.is_active:
                # reward affiliate here, your custom logic is here
                Transaction.objects.create(
                    user=self.affiliate.user,
                    amount=Affiliate.calc_affiliate_reward(product.price))
                return super(SomeView, self).form_valid(form)
   

Optional

To always keep the aid GET parameter (maybe you don't trust the cookies or you want to reward affiliate only if his visitor make payment at current link access, and not tomorrow)

1. Load 'affiliate_tags' tags:

    {% load affiliate_tags %}
   

2. Use 'url_aff' instead of 'url' template tag:

    <a href="{% url_aff 'home' %}">Home</a>
