Django unable to load model into views - django

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.

How Should i import the Model Class on django to other py file to use it?

I wanted to insert model instance to database from a file. Ι wrote a python program to do so by importing models but every time Ι get this error:
ModuleNotFoundError: No module named 'exams'
I have tried putting the file in the same folder but then I got:
"Relative import error"
the expected result was to save model instance in the database.
You need to include more details, at least your files' paths. But if we assume that both models.py and I guess views.py files are in the same folder you should use:
from .models import exams
Unless what you are trying to import is the django models. In that case you use:
from django.db import models
As I said your questiong is poorly written and needs improvement to better understand your problem.

ModuleNotFoundError: No module named 'foo'

I´m trying to make a cron inside my django app with django-crontab==0.7.1,.
Within my project settings installed apps, crontab app first, and then my app, both registered.
In my cron.py:
from .models import Url
urls=Url.objects.values_list('url')
def foo(url):
if url not in urls:
link= Url(
url=url,
)
link.save()
foo('https://example.org')
Also tried to put inside cron.py, but it doesn´t make sense since both are inside same app
from foo.models import Url
Also init.py inside app
My models.py inside foo app, after migrations ran
from django.db import models
class Url(models.Model):
url=models.URLField('url',blank=False,null=False)
but still getting ModuleNotFoundError: No module named 'foo'
Sorry if this has been asked before, but nothing watched yet gives me the answer
Thank you

django-oscar RuntimeError: conflicting models

Version Info: Python 2.7, Django 1.9, Oscar Commerce - VERSION = (1.3)
I am trying to customize Products and few other models in the catalogue app following the documentation.
I have forked catalogue app (to myproject/forked_apps/catalogue) as per documentation documentation and did this in models.py:
from django.db import models
from oscar.apps.catalogue.abstract_models import AbstractProduct
class Product(AbstractProduct):
is_active = models.BooleanField(default=False)
from oscar.apps.catalogue.models import *
I have already included the modified catalogue app, in the INSTALLED_APPS in settings.py as an argument for get_core_apps function, as stated in docs (so my local app is replacing the original app from Oscar).
INSTALLED_APPS = [
...
] + get_core_apps(['forked_apps.catalogue'])
Migrations are also copied from oscar.apps.catalogue to my local app.
When I'm trying to make migrations I'm getting this error all the time:
RuntimeError: Conflicting 'product_product_options' models in application 'catalogue': <class 'oscar.apps.catalogue.models.Product_product_options'> and <class 'forked_apps.catalogue.models.Product_product_options'>.
I tried to remove all migrations from my local catalogue app (the I copied before from Oscar app), then it works, but all new migrations are created in Oscar source code folder, but I need them to be in my project...
How do I get over this error ?
Make sure you're using the following wherever you use the Product model:
from oscar.core.loading import get_model
Product = get_model('catalogue', 'Product')
if you, in some place of your code write an import just like this:
from oscar.apps.catalogue.models import Product
you will ran into this issue.

Django 1.5.1 - Admin.py missing while running startapp

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.

django inspectdb in admin site (admin.site.register)

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.
