Re: 500 Server Error | Impossible to Fix

Okay, so I added a logging to:

> python manage.py runserver

And I found the error (which also now appears in "heroku logs --tail"). Interestingly, this thing states that:

> django.template.exceptions.TemplateDoesNotExist: store/main.html

This is impossible because in  urls.py I have my main as my base url: 

> urlpatterns = [

     path('  ' , views.main, name="main")

]

Also, in views.py I have main instantiated as:

> def main(request):

    

    data= cartData(request)

    items=data['items']

    order=data['order']

    cartItems=data['cartItems']

    context = {'items':items, 'order':order, 'cartItems':cartItems}

    return render(request, 'store/main.html', context)

 

Thus I am confused as to how the Template could be non-existent if it does in fact exist. Would you all happen to know of any solutions to this?

Hi Ranga, 

These are the last two log errors:

Thanks Ranga!

Thanks for the suggestion Kasper.

Unfortunately I have not been able to resolve the above bugs utilizing the recommended logging technique. The:

> heroku logs —tail 

Works to give me the errors mentioned previously. I just wish that there was a way for heroku itself to provide more detailed and precise 500 server errors. The current logs for Heroku is not informative enough.

I don't know anything about deploying on Heroku, but as others have

pointed out, you should definitely look into how to get some more

detailed log information:



https://docs.djangoproject.com/en/3.1/topics/logging/



I've personal set up my logging so I get an email with detailed

information in case of an internal server error. That works quite well

for my use case, but yours might be very different.



There's no reason wasting time trying to guess what is wrong, you want

to be able to get hold of the detailed error information sooner or later

anyway so start by figuring out how you can do that as the very first thing.



Kind regards,



Kasper Laudrup
