When trying to override the ModelAdmin constructor using the decorator
@admin.register I get an exception.
This is an example for a new project called "what" with an simple app
"why":
Commands to create the files (I used django 1.8.4):
django-admin stratproject what
cd what
python manage.py startapp why
what/settings.py
{{{
...
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'why',
)
...
}}}
why/models.py
{{{
from django.db import models
# Create your models here.
class WhyMe(models.Model):
name = models.CharField(max_length=255)
}}}
why/admin.py
{{{
from django.contrib import admin
from why.models import WhyMe
@admin.register(WhyMe)
class WhyMeAdmin(admin.ModelAdmin):
def __init__(self, *args, **kwargs):
super(WhyMeAdmin, self).__init__(*args, **kwargs)
print("Whaaaaatttt???")
}}}
If I run the command 'runserver' I've got:
{{{

However, if I use the normal registration 'admin.site.register(WhyMe,
WhyMeAdmin)' everything works fine.
This also happens with latest 1.8.x, 1.9.x and 1.10.x
