Firstly, I created a class that has __init__() on it in models.py, as you can see below. And when I import it in my views.py, the vscode intellisense also shows that my class takes 4 arguments. But when I try to run the program, it shows me an error saying that the class doesn't take any arguments. Any help would be appreciated, ty.
models.py:
from django.db import models
class destination:
def __init__(self, name, desc, price, img):
self.name = name
self.desc = desc
self.price = price
self.img = img
views.py:
from django.shortcuts import render
from .models import destination
dest1 = destination('Bali', 'Nice place to visit', 1000, 'destination_1.jpg')
dest2 = destination('Mumbai', 'The city that never sleeps', 500, 'destination_2.jpg')
dest3 = destination('Sylhet', 'The city of tea', 100, 'destination_3.jpg')
dests = [dest1, dest2, dest3]
def travello(req):
return render(req, 'index.html', {'dests': dests})
When I run python3 manage.py runserver:

Running your Code snipped like it is works for me and the code snipped doesn't really tell the problem, so I expect you import another destination at some point, that you did not provide in your snipped or is hidden behind another import. I would recommend renaming your class e.g. Destination (using upper letter is the recommended way to write class names anyways) and see if that solves your problem.

I have not been able to find my issue anywhere else on the web as this module is relatively new, however could anyone give some insights on this issue. Perhaps it has something to do with setting.py file?
I have installed drf-extensions and imported it to my views. After that, I started getting below exception and I was not able to identify the root cause of this. Can someone explain me, what went wrong here pls?

If I disable the extension import then I can run fine. I am using three models and have written serializers and trying to make an nested API using drf_extensions.
I guess the problem is related to this issue: https://github.com/chibisov/drf-extensions/issues/294
Temporary fix for me was to uninstall and install with:
pip install -U git+git://github.com/chibisov/drf-extensions.git#8001a440c7322be26bbe2d16f3a334a8b0b5860b

It looks like you are passing the string representation of the name to include() rather than the actual articles.urls variable. Instead, it should look something like this:
from articles import urls as article_urls
...
urlpatterns =[
url(r'article/',include(article_urls, namespace='article'))
]
the problem is explained in this way:
skcms/urls.py
from django.urls import include, path
urlpatterns =[
path('article/',include('articles.urls')),
]
articles/urls.py
from django.urls import path
from . import views
urlpatterns =[
path('', views.articles, name='articles'),
path('', views.article, name='article'),
]

ImportError: cannot import name 'Seasons'
I randomly got this error in my recent django app. I am not sure why. The models import in other apps/files in my project. Any help is appreciated.
I believe you faced circular model import. Seems like you are importing User into seasons.model and Seasons into users.model.
If you use them as a foreign key you can set it as:
user = models.ForeignKey('users.User')
So I'm trying to open and print data from this JSON file using this code in my view:
from django.shortcuts import render
import json
class OnlicarView():
import json
from pprint import pprint
with open('C:/Python34/Scripts/onlicar/mytest/onlicar/static/json/vehicles.json') as data_file:
data = json.load(data_file)
pprint(data)
Here is my app url:
from django.conf.urls import url
from onlicar import views
urlpatterns = [
url(r'^onlicar/$', views.OnlicarView.as_view(), name='onlicar_signup'
)
]
Here is my root url:
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^onlicar/', include('onlicar.urls'))
I am having trouble with the app url. I am getting an error saying that there is an Attribute Error and I don't know how to fix it.
Because I am getting the data from a JSON file there is nothing in my models at the moment. Am I meant to have something in the models?
My JSON file is printing now, but how do I render it to HTML instead?
Here is the error:

There are a lot of things wrong with this code.
Firstly, you have declared this as a class, and used it in the URL as if it were a class-based view, but you do not inherit from any actual view class.
Just as seriously, in a class you do not put code at the class level; it needs to go inside a method.
Also, pprint will only print to the console, it will not display anything in the user's browser; you need to create a response and return that.
