Writing your first Django app, part 1 - Can't Follow it

[michaela...@gmail.com]

Hi,

I am running into the same problem as this:
http://stackoverflow.com/questions/30493018/404-error-in-writing-your-first-django-app-tutorial

Now I can just follow the Alasdair's recommendation and delete the polls/url.py file, but the tutorial is very clear about having two separate urls.py.
Is this a mistake in the tutorial?

I even copied and pasted the tutorials code and tried to run it and it still gave the same error:
ImportError: No module named 'polls.urls'

Very confusing for a first step tutorial, maybe this could be corrected if it is an issue?

Kind Regards

[Bipul Raj]

I remember doing the django tutorial long time back, it just works.

The import error means that file polls/urls.py is not there. Check may be you have left "s" in ulrs. You might have created polls/url.py.

I believe it is because your (MySite) is in upper case.

ROOT_URLCONF = 'mysite.urls'

must be:

ROOT_URLCONF = 'MySite.urls'

If you follow the official tutorial, you will have two urls.py files.

One is located at mysite/mysite/urls.py, having been created by the 'startproject' command. This is your primary urls.py file that is referenced in your settings.py as the starting point for all URL lookups by default, as automatically configured by the 'startproject' command.

The second will be located at mysite/polls/urls.py, and is created by the 'startapp' command listed in the tutorial. This file is referenced by your primary project urls.py using an include() function. Any URL's that match the regular expression for the include statement in your primary file will then begin searching through your app urls.py for further matches.

If you are on a Linux host, everything is case-sensitive, so make sure your upper/lower case code references match your actual directory structure.

Still having this problem- no solution found

Give the polls.urls in quotes like this. 

"polls.urls"

To Sammy,

Are you sure your urls.py is in the correct file directory? As in it should be in mysite/mysite/urls.py instead of mysite/urls.py

To Lim Kai Wey,

I am fairly certain that the directory is not the problem. However, since this is my first Django project, I am pretty certain I've missed something. I attached some pictures to better illustrate what I've done.

Got the solution to your problem

[Franck Tchouanga]

Firstly in your mysite/mysite/URLs.py in the url patterns portion instead type this

Urlpatterns=[

Path('',include ('polls.URLs')),
Path('admin/',admin.site.URLs),
]

[Franck Tchouanga]

In the mysite/mysite/setting.py do as follows

INSTALLED_APPS=[
'Polls.apps.pollsConfig',
""""
The rest of the code
"""
]

So you should erase the polls you wrote at the end. Hope will be helpful waiting for your feedbacks

[Franck Tchouanga]

I wanted to precise at the level of the syntax from what I wrote above

Urlpatterns = [

Path(' ',include('polls.URLs')),

Path('admin/', admin.site.urls),
]

[Lim Kai Wey]

I do agree that you Sammy could try changing the mysite/mysite/setting.py

  INSTALLED_APPS=[
        'polls.apps.PollsConfig',

         """"
           The rest of the code
          """
       ]  

And I too was wondering if he placed 'polls/' as his URL in mysite/polls/urls.py that cause the error. (IF that is the case)

But in my opinion, for future development purposes and good practice to know which django app you are at while browsing at webpage.

Remain the mysite/mysite/urls.py as it is. The code should be:

from django.contrib import admin

from django.urls import include, path

urlpatterns = [

path('polls/', include('polls.urls')),

path('admin/', admin.site.urls),

]

and instead change the mysite/polls/urls.py The code should be:

from django.urls import path

from . import views

urlpatterns = [

path('', views.IndexView.as_view(), name='index'),

]

Please do correct me if I am wrong. Hope it helps.

Regards,

Kai Wey

Besides that, I do recommend Morzilla's Django Tutorial too, as it covers more in the tutorial compared to Django's own tutorial.

Just out of curiosity, Python is case sensitive. The function names, 'path' and variable 'urlpatterns'.  I have gone through the tutorials with no problem.

Hi,

I also having the same problem. And the actual reason was (poll instead of polls). Please check once in your view or url file. I am sure you also having the same issue.

You check your app name ,then check 

Include ('appname.urls')

U also create urls.py inside your app.

Yes, so respect the syntaxes exactly it is written by default in django, its a better practice to avoid unwanted errors.

Just need to  give modification depending on the project you created
