Model not appearing in django admin

[Thomas Brightwell]

I am trying to manage the data in a model through the default django admin site. I have several apps, which have all been included in INSTALLED_APPS, and I am registering the model with the default django admin. I have included the django admin app in urls.py and have verified that I am the superuser with all permissions. I know the model is importing because it is included in the permission settings, but the option to edit / create new model objects for Retailer is not available on the admin home page. 

Any pointer in the right direction would be appreciated. 

===================

webappconf/settings.py

## APPLICATION DEFINITION

INSTALLED_APPS = (

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'webapp',

    'scrape',

    'style',

)

[...]

ROOT_URLCONF = 'webappconf.urls'

webappconf/urls.py

from django.contrib import admin

[...]

url(r'^admin/django_admin/', include(admin.site.urls)),

webapp/models.py

# Retailers

class Retailer(Model):

    display_name = CharField(max_length=50)

    source = CharField(max_length=50)

    logo = CharField(max_length=100)

    basic_descripion = TextField(max_length=2000)

    class Meta:

        db_table = 'retailer'

webapp/admin.py

from django.contrib import admin

from webapp.models import Retailer

class RetailerAdmin(admin.ModelAdmin):

    pass

admin.site.register(Retailer, RetailerAdmin)

From the permission options for superuser (who has all permissions)

webapp | retailer | Can add retailer

webapp | retailer | Can change retailer

webapp | retailer | Can delete retailer

Hi,

You can start by entering the model url manually after logging to the admin interface, in your case it would be

http://[host name]:[port]/admin/django_admin/webapp/retailer

don't forget to set your DEBUG to True in the settings.py and if you are restart your server if you are running gunicorn or anything alike.

Do you have admin.autodiscover() in your urls.py? (assuming you're not using version 1.7)

[Thomas Brightwell]

Chedi,

Thanks for the quick response.

^style/

The current URL, admin/django_admin/webapp/retailer, didn't match any of these.

Collin,

I'm running django v1.7c1

[chedi toueiti]

I see that you have other routes beginning with ^admin/, this can some time cause the non inclusion of certain urls depending on the order in which they appear in the urls.py file. Can you comment the other ones and just keep

url(r'^admin/django_admin/', include(admin.site.urls))

to eliminate this possibility.

[Thomas Brightwell]

Chedi,

I commented out the other lines leaving this:

urlpatterns = patterns('',

    # ##################

    # DJANGO ADMIN

    # ##################

    url(r'^admin/django_admin/', include(admin.site.urls)),

    # ##################

    # STYLE TEST

    # ##################

    url(r'^style/', include('style.urls')),

)

And got this error for http://localhost:8000/admin/django_admin/webapp/retailer

[Collin Anderson]

Wow. Is the admin.py file actually getting run? (try a print statement or try throwing an exception)

[Thomas Brightwell]

Collin,

Thanks for the help. I updated my admin.py with this (also been trying other variations of the register):

from django.contrib import admin

from .models import Retailer

@admin.register(Retailer)

class RetailerAdmin(admin.ModelAdmin):

    pass

print 'foo'

raise Exception()

Restarted my webserver and http://localhost:8000/admin/django_admin/ loads without error. I have debugged right through the loading on startup and checked django-admin is attempting a module import of the webapp.admin, and it does seem to be trying.

[Collin Anderson]

Do you have a webapp/__init__.py file? Can you import webapp.admin in
./manage.py shell?

[Thomas Brightwell]

Yes, have an __init__.py file. And yes, works fine importing.

bash-3.2$ ./manage.py shell

Python 2.7.5 (default, Mar  9 2014, 22:15:05) 

In [1]: import webapp.admin

In [2]: 

webapp directory listing:

bash-3.2$ ls

__init__.py admin admin.pyc item migrations models.pyc templates tests view

__init__.pyc admin.py fixtures locale models.py search templatetags util views.pyc

[Thomas Brightwell]

Ok, figured it. I have an admin folder as well as admin.py so they're conflicting. 

Removing it solved the issue and Retailer now appears in the admin interface. 

Thanks for the debugging steps!

Cheers,

Tom
