You’ll need to share more details, as it’s impossible to know what the issue could be. Can you share your urls.py file at the very least?

Does http://127.0.0.1:8000/learning_logs/ also not work?

ealalin · December 2, 2023, 10:31pm

non it does not work ; i have also try to add a test path

but this is not working

Side note: When posting code here, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code (or template, or error message), then another line of ```. This forces the forum software to keep your code properly formatted.

I’ve taken the liberty of editing your post to correct this, please remember to do this in the future.

KenWhitesell · December 3, 2023, 12:28am

Which urls.py file are you showing here? (What directory is it in?)

If it’s not the same file as what your settings.py file is referring to, please post that urls.py file as well.

ggothreau · December 3, 2023, 4:32am

Hi @ealalin do you have the project on a public repository like Github so I can take a look at the code?

ealalin · December 3, 2023, 6:19am

it’s the files that I use for the starting project has requested I will put this into gitub.
I hope that thus answer your question

best regards

KenWhitesell · December 3, 2023, 6:25am

No it doesn’t. We’re looking for specifics here. What is your urls setting in your settings.py? What directory is this urls.py file in?

ealalin · December 3, 2023, 8:20am

I have add some thing who can help you into github ( where I m not really at home)

but I had trouble to create the sub durectory

KenWhitesell · December 3, 2023, 2:06pm

The issue is in your urls.py file. You have two definitions for urlpatterns, and the second overrides the first. (We would have seen this if you had posted the complete urls.py file above. This is an example of why we often ask to see the complete files, and not just an edited portion.)

ggothreau · December 3, 2023, 4:28pm

Yep, what @KenWhitesell said is exactly correct. Within urls.py you are defining urlpatterns twice, once beginning on line 26, and then on line 44, which overrides what you have done on line 26. If you remove lines 44 - 46 you will probably see that it begins working as expected.

@ealalin Supprimer les lignes 44 à 46.

ealalin · December 3, 2023, 6:03pm

thankx for this answers , i m busy now to fit all this to github then , I will correct this , I keep you posted , once again thx

ealalin · December 4, 2023, 7:52am

I have corrected my urls
from django.contrib import admin
from django.urls import path

added by alain 30/11/2023

from django.urls import path

To this import statement

from learning_logs.views import My_View

urlpatterns = [

 path("learning_log/", My_View.as_view(), name="my_view"),
 path('admin/', admin.site.urls),

]
there is a better reaction of the server

but I still have a problem with this part:

from learning_logs.views import My_View

the learning_logs.views is not seen by python !!!
under the directory
Directory of C:\learning_log\learning_logs
I have the file : 02/12/2023 23:57 419 strong text views.py
and in the views.py I have the class My_View(View):

class My_View(View): # Correct class definition
def get(self, request, *args, **kwargs):
return HttpResponse(“Hello, World!”)

This is the result of the runserver

Page not found (404)

Request Method:	GET
Request URL:	http://127.0.0.1:8000/

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

learning_log/ [name=‘my_view’]
admin/

The empty path didn’t match any of these

The ad work

Django administration

here are my file

Create your views here.

from django.views import views

** 30/11/2023 add from alain *

class My_View(View): # Correct class definition
def get(self, request, *args, **kwargs):
return HttpResponse(“Hello, World!”)

To make your work easier am recreating this environment on gethub.
But I have still probleme with the transfer of these file in it . I 'm not faar from the solution :

ggothreau · December 4, 2023, 4:46pm

@ealalin it doesn’t appear that you have a root / home page configured in your urls.py file, and that is the error you posted. You will only get responses for the /learning_log/ or /admin/ subdirectories, which is why you’re getting a 404 error on /

(ggothreau). I m not sure I understand your comment, and it’s indeed difficult to test it without image , but I work on it .

in my directory : (ll_env) C:\learning_log>cd learning_logs
I have a file admin.py contening the following

from django.contrib import admin

from learning_logs.models import Topic , Entry

#from .models import Topic , Entry

After works directlly with git here is a short resume :
My first attention was to give you a model to be abble to test it directlly in github.
My problem: I was not abble to push it.
My first trial was to generate a ssh key l; load it into github and use a ssh link , the ssh link is working but the push not , here is the solution (simple when you know it)
he error message is indicating that your local branch (main ) is behind the remote branch (origin/main ). This typically happens when changes have been made to the remote branch that you don’t have locally. To resolve this issue, you need to integrate the remote changes into your local branch before pushing again.

You can follow these steps:

Fetch the Remote Changes:

git fetch origin

This command fetches the changes from the remote repository, but it doesn’t merge them into your working branch.

Merge the Remote Changes into Your Local Branch:

git merge origin/main

if you want to combine steps 2 and 3 into one command, you can use:

bas git

git pull origin main --rebase

C:\learning_log>git fetch origin

remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0

Unpacking objects: 100% (3/3), 619 bytes | 38.00 KiB/s, done.

From ssh://github.com/ealalin/learning_log

[new branch] main → origin/main

C:\learning_log>git push -u origin main

To ssh://github.com/ealalin/learning_log.git

! [rejected] main → main (non-fast-forward)

error: failed to push some refs to ‘ssh://github.com/ealalin/learning_log.git’

hint: Updates were rejected because the tip of your current branch is behind

hint: its remote counterpart. Integrate the remote changes (e.g.
