[FIXED] Using the URLconf defined in Django tried these URL patterns in this order:

Issue

I have a django app. And some upload functionality.

The page with the upload function is loading correcttly.

But after I do a submit. I get this errror:

Page not found (404)
Request Method:     POST
Request URL:    http://127.0.0.1:8000/main/

Using the URLconf defined in schoolfruitnvwa.urls, Django tried these URL patterns, in this order:

    admin/

The current path, main/, didn’t match any of these.

so this is the views.py

from .forms import ProfileForm
from .models import UploadFile


# Create your views here.
""" def store_file(file):
    with open("temp/hello.png", "wb+") as dest:
        for chunk in file.chunks():
            dest.write(chunk) """


class CreateProfileView(View):
    def get(self, request):
        form = ProfileForm()
        return render(request, "main/create_profile.html", {
            "form": form
        })

    def post(self, request):
        submitted_form = ProfileForm(request.POST, request.FILES)

        if submitted_form.is_valid():
            uploadfile = UploadFile(image=request.FILES["upload_file"])
            uploadfile.save()
            return HttpResponseRedirect("/")

        return render(request, "main/create_profile.html", {
            "form": submitted_form
        })

urls.py:

from django.urls import path

from . import views

urlpatterns = [
    path("", views.CreateProfileView.as_view())
]

forms.py:

class ProfileForm(forms.Form):
    upload_file = forms.FileField()

So my question is: what I have to change?

I try it like this:

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

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

But then I cant run the app:

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.

in urls.py:

from django.urls import path
from . import views

app_name='main'

urlpatterns = [
    path("", views.CreateProfileView.as_view())
]

main urls.py:

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

urlpatterns = [
    path('admin/', admin.site.urls),
    path('main/', include('main.urls', namespace="app_main")),
   
]

settings.py:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'main',
    
]

and so the structure looks like this:

the manage.py is in the folder: schoolfruitnvwa. and in the folder schoolfruitnvwa I have the main application.

Solution

You must check the url defined in the urls.py (this files is located near your settings.py) of your project and add. Be careful Django got urls.py files I can't be a bit disturbing at the start.

In urls.py (near settings.py): :

path('main/', include('youappname.urls', namespace="app_namespace")),

In urls.py (of your app):

app_name = 'yourappname'

urlpatterns = [
    path(...your api function call...),
]
