I am following this tutoiral: https://www.ordinarycoders.com/blog/article/django-tailwind

I have a django project called 'project' with two apps in it 'app' and 'main'. I'm trying to load 'main > template > main > home.html' . but I get this error:

Internal Server Error: /

In my main>urls.py :

from django.urls import path
from . import views

app_name = "main"   


urlpatterns = [
    path("", views.homepage, name="homepage"),

In main>views.py I have

from django.shortcuts import render

# Create your views here.
def homepage(request):
    return render(request = request, template_name="main/home.html")

I've tried to add the template directory of main into DIRS in settings.py follwing this other Stack link: Django: TemplateDoesNotExist at / home.html in my project

But I haven't been able to open the html file.

Any help greatly appreciated. Thanks

Hey change this line in your settings.py from this

        'DIRS': ['C:\Users\Kaij\Documents\djangoTests\djangoTailwind2\env\project\main\template'],

to this

 [BASE_DIR/ 'templates']

and then in your main directory create a folder called templates and within that folder create another folder called main and that is where your home.html goes into. so something like this

project -> main -> templates -> home.html

and in your folder called main, create a urls.py and add these lines

from django.urls import path
from .views import some_view_name

urlpatterns = [
    path('', some_view_name, name='home-view')
]

then in main -> views.py add this line to

from django.shortcuts import render
def some_view_name(request):
    return render(request, "main/home.html")

that should some the problem for you.

your directory structure should look like something like this

project 
    -> project
          urls.py
           ...
    -> main
          ->templates
            -> main
                 -> home.html
   manage.py
   ...

If this solves your problem please don't forget to accept it as the correct answer.
