ERROR on executing "heroku logs"
The migrations work fine when running them locally with sqlite3 database but not on Heroku with PostgreSQL.
I tried running python manage.py makemigrations & python manage.py migrate on Heroku but no luck.

I deployed a django app using a postresql database with Heroku.
The app works perfectly on my local machine but when I want to create a user or to login using the deployed app, I run into the following error:

I believe this error has something do to with my postgres database, but I don't know what relevant code to share in that case.
Please, let me know if you have any idea how to solve that issue.

This page is opening when i am trying to add an object, can anyone help?

From command line

Try to run migrations:
python manage.py makemigrations
python manage.py migrate
The first line of the error explains the core issue:
OperationalError at / no such table: core_document
The table which is being referenced doesn't exist. This usually happens when migrations haven't successfully run. To begin troubleshooting (and to possibly fix the problem entirely), run the Django migrations:
python manage.py makemigrations
python manage.py migrate
I am trying to install "Django Registration Redux".
I followed every step in the official website to install.
When I am installing django.contrib.sites, the admin doesn't work, and when I comment this the admin starts working but registration does not work in either way.
It gives the error as:
DoesNotExist at /accounts/login/
Site matching query does not exist.

It sounds like you haven't followed the instructions to enable the sites framework.
After adding django.contrib.sites to INSTALLED_APPS, you need to set SITE_ID = 1 in your settings, then run the migrate command.
I have an application in Django that I deploy in heroku.
The deploy works well, but my model's database was not migrate.
After the deploy, I run again localy:
python manage.py makemigrations
python manage.py migrate
After, I do:
heroku run python manage.py makemigrations
heroku run python manage.py migrate
And after I run the server and wait it works well:
heroku run python manage.py runserver
I have 3 models:
cliente, categoria, produto
produto has a ForeignKey to categoria. So, localy, I have 3 databases:
produtos_produto, produtos_categoria, cliente.
I use PostgreSQL as database localy and in heroku.
But in heroku, I don't have any of this databases.
When I run the server, in browser I have the following answer:
ProgrammingError at /

You must run makemigrations locally, then commit those generated migration files to git. Heroku will run then automatically when you deploy.
