Model Customization and Oscar Administration Panel

[christia...@abinsula.com]

Hi A/all,
I'm trying to modify OSCAR "Product" model, in order to add fields to the model.
These are steps I followed:

1) For of the catalogue app
2) Created my custom Product as follows:

from django.db import models
from oscar.apps.catalogue.abstract_models import AbstractProduct

class Author(models.Model):
    name = models.CharField(max_length=300, null=False)
    birthdate = models.DateField(null=True)
    biography = models.TextField(blank=True, null=True)
    picture = models.ImageField(null=True)

class Product(AbstractProduct):
    author = models.ManyToManyField(to='Author', related_name='authors', blank=False)
    synopsys = models.TextField(blank=True, null=True)



#Stands at the bottom of the declaration
from oscar.apps.catalogue.models import *  # noqa

3) Applied migrations.

Everything goes right but... How can I reflect my changes in the administration panel in order to Add models and edit existing ones?

Thanks in advance,
Christian

from django.contrib import admin
from oscar.apps.catalogue.admin import *
from .models import Product


admin.site.unregister(ProductAdmin)

@admin.register(Product)
class CustomProductAdmin(ProductAdmin):
   fields = ProductAdmin.fields + ['author']

This doesn't work with Oscar 1.5.2 and Django 1.11.10.

I get the following traceback

Any ideas?
