you should migrate apps to databases.
try this:
first step: you should login to heroku in terminal.
heroku login
and then try this:
heroku run python manage.py migrate
and you can also DEBUG=True to have Django show errors.

you can try like;
DEBUG = True
ALLOWED_HOSTS = ['*']

No such table on django website deployment on Heroku

I was previously facing issues on deploying my django app on Heroku regarding static directories.But now that I have been able to deploy my website after changing settings.py , there is a error being thrown called 'no such table'.Then I went to stackoverflow for solutions but nothing worked.I am adding my settings.py file here which also has the stackoverflow solutions.I have written a if statement for using PostgreSQL as mentioned in a stackoverflow post but that also don't work.You may see that if statement in last line.My requirements.txt is all correct , so no problem in that.Plz help me.

When deploting Django i always follow this tutorial.
https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Deployment
In the comments you told me that you did makemigrations and then migrated before you deployed.
These things have to be done after deployment on the heroku side as they will be making the tables on the heroku database.

Django Microsoft Authentication

I'm trying to include in my Django website the possibility to sign in using a Microsoft login.
I have set up a new App registration and included the below as redirect urls.
I then followed this set of instruction in my Django site:

In urls.py I've included this line

However when trying to access the admin module and click Microsoft, I'm getting this error.
django version: 3.0.4
python version: 3.8.5

It seems that the issue was that i did not change the localhost in my sites model. As soon as I have implemented that change the issue was sorted.

This site can’t be reached - Django

I am getting This site can’t be reached and pop up window python quit unexpectedly error when trying to run Django project. It is only one particular project getting me this error any other project works perfectly.
So far I tried to all the possible solution you might think of such as running it as http://127.0.0.1:8000/, http://0.0.0.0:8000/, or http://localhost:8000/, changed ALLOWED_HOST = ['*'] and ['127.0.0.1'] but none of them seem like work

Whitespace matters. Change the following line:
{% if widget.value !=None %}
to
{% if widget.value != None %}
