File not found when adding a new app

Using Django Mystery Errors
1

Hello

I have added a new app Verge3D to my First app

Main urls.py

path('verge3D/',include('verge3D.urls')),

In my urls.py / Verge3D app :

urlpatterns = [
    path('home3D',views.myFirst3D,name="home3D"),
]

In my views.py / Verge 3D app

def myFirst3D(request):
    print("on y est")
    return render(request,'3Dfiles/earth.html')

The problem is :

Django searches this 3Dfiles/earth.html still in my first app location (it works when I create this directory/files in my fist app Templates directory)

Did you add your new app to the INSTALLED_APPS setting? What does your TEMPLATES setting look like?

3

Yes the new app was intalled in setting.py

For the templates variable, as I have APP_DIRS’: True I thought Django checks in every templates app folder.

TEMPLATES = [

    {

        'BACKEND': 'django.template.backends.django.DjangoTemplates',

        'DIRS': [],

        'APP_DIRS': True,

        'OPTIONS': {

            'context_processors': [

                'django.template.context_processors.debug',

                'django.template.context_processors.request',

                'django.contrib.auth.context_processors.auth',

                'django.contrib.messages.context_processors.messages',

            ],

        },

    },

]

It does, if the app is installed in INSTALLED_APPS and APP_DIRS == True. (Which you have in both cases.)

So you have a directory named verge3D/templates/3Dfiles, where verge3D is your new app, and that directory has earth.html in it? What does your project directory structure look like?

Here is a screenshot. The main project is zer0day with this structure in setting.py

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'events',

    'members',

    'verge3D',

    'crispy_forms',

]

Just one more thing to confirm - in your verge3D/templates directory, you have a directory named 3Dfiles with the earth.html in it?

If you don’t have earth.html in your events/templates/3Dfiles directory, you mention an error. Can you post that complete error? (Specifically, near the top of the error there should be output showing the directories being searched.)

7

Yes the earth.html page is located inside verge3D/templates/3Dfiles
Which is strange as it works for the 2 others app

Here is the message log

So in the Template-loader postmortem section, it’s showing you the directories that it’s searching. The one you’re asking about is the next-to-last entry. Django is looking in the right location. There’s no Django-based-reason why it shouldn’t be able to find it. Usually then the problem ends up being a typo in the file name or incorrect file permissions or (in the case of a Unix-style system) a reference to a file with the wrong upper or lower case in the name.

I have created a new app without “3D” inside and it works

Don’t ask me why
