My model does not show up in the Django admin.
I don't understand this. I have been doing this several times before:
from django.contrib import admin
from djntra.models import Thing
class ThingAdmin(admin.ModelAdmin):
pass
admin.register(Thing, ThingAdmin)
I have no clue what's going on.
There was a typo in my code. You need to use admin.site.register(). The site was missing.
This works:
from django.contrib import admin
from djntra.models import Thing
class ThingAdmin(admin.ModelAdmin):
pass
admin.site.register(Thing, ThingAdmin)

I'm trying to manage my User table with django.contrib.admin
But during I add the User table in admin, I had an issue that doesn't appear in admin site.
Here is my code.
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User
#admin.register(User)
class CustomUserAdmin(UserAdmin):
pass
assert admin.site.is_registered(User) # Fails here
And when I added the other custom model, it works.
Thanks
When you modify or implement the user model, you have to be aware of AUTH_USER_MODEL.
I changed AUTH_USER_MODEL in setting.py, and it starts to work.
Thanks.
Let's say I have two models, in different apps. App Two knows about app One, but not the other way around:
# one/models.py
from django.db import models
class One(models.Model):
pass
# two/models.py
from django.db import models
from one.models import One
class Two(models.Model):
one = models.ForeignKey(One)
I also have One registered in the admin site:
# one/admin.py
from django.contrib import admin
from .models import One
admin.site.register(One)
How do I register Two as an Inline on One's admin page, without introducing a circular dependency between the two apps?
You can do this pretty simply, providing you don't mind accessing a 'private' attribute on the ModelAdmin. (Attributes beginning with an underscore are treated as private by convention.)
# two/admin.py
from django.contrib import admin
from one.models import One
from .models import Two
class TwoInline(admin.StackedInline):
model = Two
admin.site._registry[One].inlines.append(TwoInline)
I had the same issue but solved it more gentle way.
# one/admin.py
class OneAdmin(admin.ModelAdmin):
model = One
admin.site.register(One, OneAdmin)
# two/admin.py
class TwoInline(admin.TabularInline):
model = Two
import one.admin
class OneAdmin(one.admin.OneAdmin):
inlines = [TwoInline]
admin.site.unregister(One)
admin.site.register(One, OneAdmin)
As you see I extended the original ModelAdmin from first app and added inlines from second app. Don't forget to unregister the model from first app before registering it again.
It's safe and much better than to access private member of the class as was suggested.
I would try the following:
# one/admin.py
from django.contrib import admin
from one.models import One
from two.models import Two
class TwoInline(admin.StackedInline):
model = Two
class OneAdmin(admin.ModelAdmin):
inlines = [TwoInline,]
admin.site.register(One, OneAdmin)
You can read more at the docs.
Has anyone seen this before? I've tried making new apps, projects, etc.
All thats in my admin.py file is:
from django.contrib import admin
from . models import UserProfile, Tribe, Membership
# Register your models here.
admin.site.register(Tribe)
admin.site.register(Membership)
admin.site.register(UserProfile)
I've not got any static files or css in the app..?
Create a class that inherit admin.ModelAdmin, update the fields to be shown in the list_display tuple, and register TribeAdmin instead of Tribe. Do the same for the rest.
from django.contrib import admin
from . models import UserProfile, Tribe, Membership
# Register your models here.
class TribeAdmin(admin.ModelAdmin):
list_display = ('field_1', 'field_2',)
admin.site.register(Tribe, TribeAdmin)
# admin.site.register(Membership)
# admin.site.register(UserProfile)
For all the available options, have a look at the documentation or an easy to understand beginner tutorial from the DjangoBook (please note its for an outdated Django Version, but fields works with Django 1.8)
With Django 1.8 you can use.
#admin.register(Tribe)
class TribeAdmin(admin.ModelAdmin):
list_display = ('field',)
I followed the django import-export manual but the Import Export buttons do not appear in my admin screen.
This is what I have in my admin.py. Is there anything else I need to do? I have added import-export to my settings.py.
from django.contrib import admin
from costtool import models as m
from costtool.models import UserProfile, Prices
from import_export import resources
from import_export.admin import ImportExportModelAdmin, ImportMixin
class PriceResource(resources.ModelResource):
class Meta:
model = Prices
class PriceAdmin(ImportExportModelAdmin):
resource_class = PriceResource
pass
admin.site.register(UserProfile)
admin.site.register(Prices)
Just tell the admin what ModelAdmin to use:
admin.site.register(Prices, PriceAdmin)
You can check Django's ModelAdmin doc and try to use the new register decorator if you're using Django 1.7
I've got sorl-thumbnail up and running in templates with Redis to store the thumbnails. Great stuff!! However, I would like to have thumbails in my Admin. I used the example in the documentation (see below) but with no luck.
from gallery.models import Photo
from django.contrib import admin
from sorl.thumbnail.admin import AdminImageMixin
class PhotoAdmin(AdminImageMixin, admin.ModelAdmin):
pass
admin.site.register(Photo, PhotoAdmin)
What am I doing wrong?
I do something very similar and it works for me. However, I use a slightly different method, importing my admin from a utils/admin.py in my site base instead, allowing easy inheritance across my models with other apps such as django-reversion, django-guardian, and django-markitup.
gallery/admin.py:
#from django.contrib import admin
from utils import admin
from gallery.models import Photo
class PhotoAdmin(admin.ModelAdmin):
#your customizations
admin.site.register(Photo,PhotoAdmin)
utils/admin.py:
from django.contrib.admin import *
from django.db import models
from sorl.thumbnail.admin import AdminImageMixin
class ModelAdmin(AdminImageMixin, ModelAdmin):
pass
Your model's ImageFields need to be sorl's ImageField (from sorl.thumbnail.fields import ImageField) instead of the standard django.db.models.ImageField.
This field is a drop-in replacement, so just updating this should fix the issue, or at least it did for me. If you are using South for database migrations, note that it will generate one for this, which is fine.
