For some reason, when I add a new model and use Django South to sync the database by: /manage.py schemamigration myapp --auto and then the migrate line, I still can't see the model on the admin page.
South does say that it added the model though.. so I'm not sure what's going on..
Any thoughts?
Just because you created the model and synced it, does not mean it gets added to the admin page automatically. You must create an admin.py file in your app directory that contains
from django.contrib import admin
from .models import MyModel
admin.site.register(MyModel)
and make sure you have admin.site.autodiscover() in your main urls.py
This should all be covered in the tutorial pages for Django. Go back and RTM.

I am trying to import my models into views.py but I am unable to do so. However I am able to register them on the admin site but when I use the same code I used in admin.py to import the models into views.py, I get an error. I am using djongo so I am not sure if that changes anything about how to import them and I cannot seem to find the documentation for it.
models.py
from djongo import models
class Round(models.Model):
round_num = models.IntegerField(default=0)
admin.py
from django.contrib import admin
from .models import Round
admin.site.register(Round)
views.py
from .models import Round
When I try and run my views.py file I get the following error: ModuleNotFoundError: No module named 'main.models'; 'main' is not a package
Also my views, admin, and models file are all in the same directory. I have made the migrations and I can see my Round model in MongoDB. The only thing I cannot do is import it to the view
You need to have an __init__.py file in your directory. It should be inside of your main folder and at the same level as your views.py and models.py
As a workaround, since the models properly migrate to MongoDB. Using pymongo I have just connected to Mongo and have rendered data into my views this way. It works fine so if anybody else has an issue loading in their models, you can always just connect directly to the DB.
I've been following the DjangoProject tutorial. When I run python manage.py startapp newapp while in the same directory as manage.py. In the newapp directory I see init.py, models.py, tests.py, and views.py but not admin.py file. Where is admin.py?
I am running Django 1.5.1 in Windows 8
You have to create an admin.py file.
you don't necessarily need an admin.py file,
just import the admin module in your models.py file,
from django.contrib import admin
and for each model do the following:
admin.site.register(model1)
admin.site.register(model2)
However, this is not best practice, but since it's just a tutorial, it will work.
You also need to uncoment the relevant lines in the urls.py file
I think I had the same frustrations following the DjangoProject tutorial - however, when I cross-referenced it with with the DjangoBook tutorial (for the same version, I believe, 1.5.1), I found that an admin.py file was not necessarily created after a python manage.py startapp xyz command -- moreover, I also uncommented all of the admin options in urls.py, views.py, and settings.py - so a bit of a mix of what Neal and Ibrahim said
You have to create your own admin.py file in the app if you want it. Indeed, this file is optionnal and isn't created by startapp.
If you want a default template to begin your admin.py, it should be:
from django.contrib import admin
from models import Model1, Model2
class Model2Admin(admin.ModelAdmin):
list_display = ('title', 'content', 'date')
# Just an example, chekc docs and tutorials for more info.
admin.site.register(Model1)
admin.site.register(Model2, Model2Admin)
The reason there is no default admin.py is because you don't have any models yet when you create your new application; so there is nothing to add to the admin section.
Further, you may not want to admin all the models in your application; or you may be creating an application that does not need any admin hookups; or you may not be using the admin application at all in your project.
Since django cannot decide this for you, there is no default admin.py generated.
To create one, if you are following the tutorial - simply keep reading and in part two you'll create the admin.py file when you learn about the admin contrib app and how to integrate it with your custom models.
I am using Mezzanine for a project. I need to add a extra field to Mezzanine blogpost.
I notice using EXTRA_MODEL_FIELDS can do it, but it looks complex.
I also try copy the blog folder from the site-package to my project path, and then modify the models.py. but I doesn't work.
I am new to Django, can some one help?
Thanks
By do some research, now I got the answer:
1. copy the blog app from sites-package to my project
2. change my setting.py
INSTALLED_APPS = (
"blog", #it was "mezzanine.blog",
.....
3. modify the blog/models.py
add following line to class BlogPost
shop_url= models.CharField(max_length=250,null=True, blank=True)
4. migirate the table (installed South)
./manage.py schemamigration blog --auto
./manage.py migrate blog
You can create a django app (CustomBlog), add it to your installed apps
and remove or comment the Mezzanine blog:
INSTALLED_APPS = (
"CustomBlog", #it was "mezzanine.blog",
...
)
In the models.py and admin.py, of your CustomBlog, inherit from the class BlogPost of Mezzanine:
models.py
from django.db import models
from mezzanine.blog.models import BlogPost
from mezzanine.blog.models import BlogCategory
class CustomBlog(BlogPost):
# Add New Field
# example
new_field = models.CharField(max_length=255)
class CustomBlogCategory(BlogCategory):
pass
admin.py
from django.contrib import admin
from .models import CustomBlog,CustomBlogCategory
admin.site.register(CustomBlog)
admin.site.register(CustomBlogCategory)
Then in the terminal create and run migrations
python manage.py makemigrations
python manage.py migrate
I have been given a small legacy db (mysql) to work with, and therefore, I have tried to use the inspectdb command in django.
So, I use something like:
python manage.py inspectdb > models.py
It works fine, and I take the models.py and copy the class it created into my app (searchapp) as a models.py file.
I have done a syncdb, and everything went fine. Results are as expected.
Now, I have tried to add this model into my admin site, using:
from searchapp.models import Abaqus
from django.contrib import admin
admin.site.register(Abaqus)
stored in a file called admin.py (Abaqus is the name of the class generated by inspectdb and searchapp is the app name). However, I am not able to see the app on the admin site. I have checked my settings.py and it includes the 'searchapp'.
I was wondering if someone could point me in the right direction..
I suspect admin.py is not loaded. You could check this by putting a debug statement just above the register call:
import pdb;pdb.set_trace()
admin.site.register(Abaqus)
If this is in fact the case, the correct way to ensure admin.py is loaded is to call django.contrib.admin.autodiscover() at the beginning of your main url conf.
If you've written no admin classes and don't want an admin.py, you can call admin.site.register(Abaqus) right below where the model is defined, inside models.py.
If you have an admin module structured like the following, import admin within models.py to ensure the code is run:
myapp
|--models.py
|--views.py
|--admin
|--__init__.py
|--views.py
|--base.py
Another possible cause would be that you are missing the permissions to edit the model. Double check that you are logged in as a superuser.
I am building a app. The app will build a Poll OR a Quiz.
So my models will have a type field(Poll, Quiz)
Now i would like to display the 2 "Types" in the admin App list. But i dont what to create two apps Poll and Quiz. Is there a way, to display the 2 options in the list and then when you click on lets say Poll, the type field is set to Poll and then you fill in the rest of the models fields.
Thanks
have a short look to the second tutorial page of django. It describes the how to do that.
http://docs.djangoproject.com/en/1.1/intro/tutorial02/#intro-tutorial02
You need to activate the admin site:
Add "django.contrib.admin" to your INSTALLED_APPS setting.
Run python manage.py syncdb.
update urls.py
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
add the next line to urlpatterns
(r'^admin/', include(admin.site.urls)),
2 . You need to add your models to the admin interface
You only have to create a admin.py in your application directory (e.g. polls) and fill in the following content:
from mysite.polls.models import Poll, Quiz
from django.contrib import admin
admin.site.register(Poll)
admin.site.register(Quiz)
you have to change the first line of course to fit with your project name.
Hope this will help!
alas!I figured it out!
What you use is a Django Proxy Model
http://docs.djangoproject.com/en/1.1/topics/db/models/#id8
So I set up a Proxy model in my models.py file and then in admin.py I just used the proxy models as Admin.
