django-mercadopago 5.0.2

Features

Our intention is not to cover 100% of the features of the upstream API, but rather provide a simple app that allows accepting and tracking payments. This should suffice for simple sites like shopping carts, online sales, etc.

Pull requests are always welcome. Please don’t hesitate to open an issue if you encounter a problem. New features will generally only be added as needed, but again, accepted if you submit a patch.

Installation

Installation should generally be done via pip:

pip install django-mercadopago

Configuration

You’ll need to obtainer your API credentials (app id and secret key) here and create an Account object with them. This creation can be done via the django admin included with this app or programmatically.

You should also expose the notifications endpoints like this:

url(r'^mercadopago/', include('django_mercadopago.urls'), namespace='mp'),
# Make sure namespace is 'mp', since we assume it is for notification URL
# contruction.

Note that these endpoints are required, since notification callbacks won’t work without them.

There are also a few Django settings that configure the behaviour of this app. All these settings are included in a single dict inside your Django settings:

MERCADOPAGO = {
    'autoprocess': True,
    'success_url': 'myapp:mp_success',
    'failure_url': 'myapp:mp_failure',
    'pending_url': 'myapp:mp_pending',
    'base_host': 'https://www.mysite.com
}

See below for an explanation of each setting.

@receiver(notification_received)
def process_notification(sender, **kwargs):
    tasks.process_notification.delay(notification=sender)

url(
    r'pago_recibido/(?P<pk>.*)$',
    order.OrderPaidView.as_view(),
    name='payment_received',
),

Usage

MercadoPago lets you create preferences, for which you’ll later receive notifications (indicating if it was paid, or what happened):

self.preference = Preference.objects.create(
    title='the product name',
    price=10.0,
    reference='order-38452',
    success_url='http://example.com/mp_done',
    account=account,
)

If your app will only be using a single MercadoPago account, just use:

account = Account.objects.first()

Finally, you can handle payment notifications in real time using a post_update hook:

@receiver(post_save, sender=MercadoPagoPayment)
def process_payment(sender, instance=None, created=False, **kwargs):
    do_stuff()

Backwards compatibility

As of v5.0.0, the notification and callback URL formats generated by v4.2.0 and earlier is no longer supported. Users must upgrade to v4.3.0, and run this version until all pending payments are completed (or expire), and only then upgrade to v5.0.0.

Note that, prior to v4.2.0, this package was called django-mercadopago-simple on PyPI. Older release exist under that name.

Version 2.0.0 changes the database schema quite a bit. While older data is retained, some missing fields had to be filled. Auto-generated data will have negative key values, and should easily be recognizable.

Regrettably, filling in this data automatically is not possible. However, there is no data loss involved.
