Facing an error in Odoo 14 during the restoring process and also while running the server on the terminal.
Surprisingly it can run on the web, just can't proceed with the login with an error when doing the same.

HINT: Perhaps you meant to reference the column "res_partner.index".
I've tried various solutions on web with the error specified, but still couldn't resolve the error.
Anyone experienced a similar issues?, if do then
how come you resolved the issue?
Thanks
First approach for this issue is: to re-create the custom-field: (example: "res_partner.gender") in your custom module, in the corresponding model which _inherit=res_partner...
Another approach:
I had a similar problem, because i had delete a custom-field from a model, but this field was still used in a view.
I could solve it by desactivating the concerned view(s) containing my custom field (website.mycustomfield) using p.SQL request:
To identify the concerned views:
SELECT public.ir_ui_view
WHERE arch_db like '%website.mycustomfield%'
To desactivate the concerned views:
UPDATE public.ir_ui_view
SET active = false
WHERE arch_db like '%website.mycustomfield%'

Probably you have two users with same login. You could try to get all users with login which you use to login in admin panel
python manage.py shell
from users.models import User
User.objects.filter(login=your_login)
than you will get queryset, and if there more than one object with same login, just delete it
Looks that its something with the settings.py. Please be sure that the settings its ok:

My app is working on my main PC. I tried to clone the app to my laptop (I tried to initialize it on PC in a different directory and the problem was the same so the problem isn't with the laptop) and when initializing the db with flask db init I got the following error:
sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) no such table: race [SQL: 'SELECT race.id AS race_id, race.name AS race_name \nFROM race'] (Background on this error at: http://sqlalche.me/e/e3q8)
What I'm trying to do is in one of my forms to include a wtforms RadioField with choices based on the race table in db. So for every row in that table I want one choice in the selection. The important part of the form looks like this:
class RegistrationForm(FlaskForm):
race = RadioField('Race', validators=[InputRequired('Choose a race.')],
choices=races, coerce=int)
And the races variable is outside the form like this (before the form itself):
with create_app().app_context():
races = [(race.id, race.name.capitalize()) for race in Race.query.all()]
I figured that this last line is the problem from the call stack:

So the problem is that I don't have the db initialized when I'm running the flask db init command and that one line needs the db to exist. This probably doesn't have a solution so I'm not asking how to correct this implementation, but how to do it correctly to have form based on rows from the db. I don't have hundreds of races so I could hardcode them in but I wanted to do it this way.
So after some googling I found that you can add the RadioField choices dynamically in the views like this:
#bp.route('/register', methods=['GET', 'POST'])
def register():
form = RegistrationForm()
form.race.choices = [(race.id, race.name.capitalize()) for race in Race.query.all()]
This is exactly what I was looking for.
Problem applying just created migration (Added db.Model) through Flask-Migrate (SQLAlchemy) for PostgresSQL DB.

DETAIL: constraint parameter_parameter_subtype_id_fkey on table parameter depends on table parameter_subtype
HINT: Use DROP ... CASCADE to drop the dependent objects too.
[SQL: '\nDROP TABLE parameter_subtype']
This leads to table not created in PostgreSQL db and columns either.
Unsure what may have caused this problem and how to understand this Error message.
I did manually drop the tables and it helped. However how to be with migration.
Any Suggestions?
Flask-Migrate does not read in the database to see the dependencies between the objects. You can achieve a successful migration by reordering the drop_table in your migration file.
What you can do is modify the migration file like so:
op.drop_table("parameter_subtype")
op.drop_table("parameter")
And then run the upgrade command. Normally ordering the drop in this order should solve the problem.
I got the same error and what worked for me was to first drop the table in the database using the command:
$ DROP TABLE table_name;
And then in the migration file in the upgrade() function delete or comment out the line where it says:
op.drop_table('table_name')
So I have a Django project that doesn't use a database (the 'DATABASES' setting is commented out). I chose to use Django as there's a chance I will need the database functionality in the future. Anyway, I've been working on and off of tbhis project for a couple of months with no problems. I'm running Linux Mint and have had no troubles using the python manage.py runserver command so far.
Well, today I fired up the app and started the local server with no problems. I then tried to open the app in my browser and received the rather hideous error message:

I've not touched the app since I last worked on it and it was working fine then. I really have no idea what this is talking about as I have no caches implemented and am not using a database... I've asked a few colleges who are familiar with Django and have no idea what this is either. Any Ideas? I've also tried setting DATABASES to an empty dict {} on the advice of a post online but to no effect. At a bit of a loss.
EDIT: Thought I should mention that in the interim since I last touched this project, I've since started and set up a new Django project that does use a database. Is it possible that this project is somehow cached and breaking the one I'm currently trying to work on?
EDIT2: I should point out that this webapp is currently live and working at http://mrcagney-maps.com. The code is exactly the same (having not touched it since I last pushed to the server). Really weird.
For future Googlers - I ran into this issue and the above solutions did not work for me. What did work for me was clearing/deleting my cookies in Chrome for the 127.0.0.1 URL. So go to Settings or press CMD+, then Cookies and other site data, then find 127.0.0.1 or localhost and delete those cookies. Refresh the local dev host page and the error should be gone. This has something to do with a corrupted session / cookie file.
I'm not sure why I started to get this error, it involved an upgrade though. I just deleted all the sessions and after logging back in all was well.
# from the shell but equivalent sql would work fine too
from django.contrib.sessions.models import Session
Session.objects.all().delete()
The error AttributeError: 'SessionStore' object has no attribute '_session_cache' can stem from the database not having a django_session table. However, since you are not using a table, you would need to make sure that you don't have the 'django.contrib.sessions.middleware.SessionMiddleware' in your MIDDLEWARE_CLASSES in the project's settings file. If it is in there, it will look for a database table which stores the sessions, causing the above error.
Here is what worked for me. Since there is no databases in your application. Admin page looks for the database be it default. So first lets create the default databases.
Shut down your servers and run
python manage.py makemigrations
python manage.py migrate
Now create the admin or superuser for your application. Fill username and password.
python manage.py createsuperuser
Now restart your server and go the admin page
python manage.py runserver
Throwed the same error for me after upgraded my wagtail version... So, for me worked even simpler solution or u didn't noticed already :D Actually I opened the browser > F12 > Storage Tab and Delete all Cookies and all other Cached Data
Users facing this issue via Postman please make sure that the value in the request header for Cache-Control is no-cache.
If not then clear the cookie data for the domain.
In normal case when we use
from django.http import JsonResponse
for sending response we have no need to uses sessions.
But when we use some package such as djangorestframework we force to use sessions.
Sessions need storage place in sqllite,mysql ,...or others
then we need run these commands:
python manage.py makemigrations
python manage.py migrate
