Django Error: __init__() takes 1 positional argument but 2 were given-CodePudding

I am new to Django and I'm trying to create my first project following a tutorial from Udemy, but I encounter this error.

My project has the following folder structure:

-demo

__ init__.py
admin.py
apps.py
models.py
tests.py
urls.py -views.py

-first

__ init__.py
asgi.py
settings.py
urls.py
wsgi.py

views.py:

from django.shortcuts import render
from django.http import HttpRequest


def first(request):
    return HttpRequest('1st message from views')

demo/urls.py:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.first),
]

first/urls.py:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('demo/', include('demo.urls')),
    path('admin/', admin.site.urls),
]

Both __ init__.py files are empty

error:

CodePudding user response：

You need to return a HttpResponse, not HttpRequest.

A request is what you get as input.

from django.http import HttpResponse

def first(request):
    return HttpResponse('1st message from views')
