Django 4.0 url import error

Using Django Forms & APIs
1

Hello i just installed the new version of Django

and I have this problem with importing the url in urls.py file

from django.contrib import admin
from django.urls import path 
from django.conf.urls import  url
from ParamsMoni.views import index , get_data


urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^api/data/$', get_data , name='api-data'),
    path('', index, name='index'),
]

I can’t import from django.conf.urls import url don’t now why and it gives me this error!

File "C:\XPTANK\Tankparms\urls.py", line 18, in <module>
    from django.conf.urls import  url
ImportError: cannot import name 'url' from 'django.conf.urls' (C:\XPTANK\venv\lib\site-packages\django\conf\urls\__init__.py)

I am using Django==4.0

my best

The url function was deprecated in 3.1 and removed in 4.0.

So think the path do the same function but when I try

`path(r'^api/data/$', get_data , name='api-data'),`

and in the views.py

def get_data(request , *args, **kwargs):
    data= {
        "sales": 100,
        "customerts": 10,
    }
    return JsonResponse(data)

and from the browser http://127.0.0.1:8000/api/data/

it gives me error Page not found (404)

it there any way to solve this?

Yes, did you read the documentation I linked to in my response?

nope, now I did :slight_smile:

so the solution is to replace the from django.conf.urls import url by

from django.urls import re_path

and

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path(r'^api/data/$', get_data , name='api-data'),
    path('', index, name='index'),
]

it works perfectly

Many thanks you are the best :slight_smile:

Now that you’ve got it working, I’ll point out that using a regex in that situation doesn’t really provide any benefit. There are no variables in that path, nothing in the way of a “pattern” needing to be matched - just a straight string comparison.

You would be just as well served using path('api/data/', get_data , name='api-data'),
