I have a projects with hundreds of migrations. When I try to run the tests it gives me the stacktrace:

Since I use the value N all over the project, this does not help much either.
How do I go about finding the migration that causes these errors?
You can add the --verbosity of -v option when running your tests, which adds more verbosity to the output of your tests:
python manage.py test -v 2
or
python manage.py test --verbosity=2
Level 2 should show you all the migrations. Level 3 even shows more details, but I don't think it'll add much in your case.
This will show you which migration is causing the issue.

I keep running into the django.db.utils.DatabaseError error with trying to migrate the database changes in a Django project.

django.db.utils.DatabaseError
I am stumped on how to solve this issue. I have tried sqlparse==0.2.4 as suggested here but it did not work for me.
Deleted everything in the migrations folder and started from scratch. The same error pops up but now it is even longer.
I understand there is a not implemented error but not sure how to fix it.
The models.py:
from djongo import models
class User(models.Model):
age = models.FloatField()
height = models.FloatField()
waist = models.FloatField()
weight = models.FloatField()
I have the following model
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE, related_name="profile")
image = models.ImageField(default='default.jpg', upload_to='profile_pics')
location = models.CharField(default=None, max_length=5)
def __str__(self):
return f'{self.user.username} Profile'
I was testing some things out and put null=True for location. Then I changed it to default=None. After that when I tried to run makemigrations followed by migrate.
I got the following error

I went through the migrations folder and changed each migration that had null=True to default=None, but I still seem to get the error? Anything I'm not seeing?
I've deployed my Django application to DigitalOcean server via nginx, gunicorn. Today I wanted to add the script models.DateTimeField(auto_now_add=True) for saving the date when message from user was sent, but during migration (after pulling the entire repository from github on ubuntu server) I'm getting following error. And I guess the problem is in migration files, but don't know how can I manipulate them on server and how to do it safely, without losing any data.

Note: I should solve this problem very quickly, please, everyone, who knows the answer, help me. I'm really depressed and stressed.
As a solution I've used deleting the migrations one by one with a command find . -path "*/migrations/{my_migration_names}.py" -not -name "__init__.py" -delete. To get name of all of my migration files you should run python3 manage.py showmigrations command.
Models.py
class user_Roles(models.Model):
code = models.CharField(max_length=20)
description = models.CharField(max_length=30)
permitted_menus = models.CharField(max_length=200)
created = models.DateTimeField(auto_now_add=True,blank=True,null=True)
I cannot add a datetime, date or time fields in models. It shows that "[u"'' value has an invalid format. It must be in HH:MM[:ss[.uuuuuu]] format."]" while migrating the database. How to fix it??

After removing the created field also, it shows the same error..
Delete the migration folder. And then execute
python manage.py makemigrations
python manage.py migrate
You can modify the created field like this
created = models.DateTimeField(default=date.today, blank=True,null=True)
Check the documentation for auto_now_add
I've added an IntegerField to a Django model, but I just can't migrate it.
I type:
python3 migrate my_app
and it tells me that there are no migrations to apply. Then, of course, my admin page outputs an error because it can't find the new column! Any ideas?
Thanks
