Django migration error while trying to migrate

I created an app two days ago, added some models, and migrated successfully. And since, I haven't added or changed anything but I added something today and tried to migrate, after making migrations and tried to migrate, I got this error:
Operations to perform:

I've been looking but can't really find what's wrong
This is my model
from django.db import models
from django.forms import ModelForm
class Users_Upload(models.Model):
first_name = models.CharField(max_length=120)
last_name = models.CharField(max_length=120)
email = models.CharField(max_length=120)
phone_number = models.DecimalField(max_digits=14, decimal_places=4)
address = models.CharField(max_length=120, default="Bay Area, San Francisco, California, USA")
and my admin
from django.contrib import admin
from .models import Users_Upload
admin.site.register(Users_Upload)

I've already solved it. I had to clear out all my migrations and re-migrate again.

Issues Deploying Django Application to AWS because of Date model

I am trying to do a simple sign in application using Django and host it on AWS using Amazon Linux
My model is
class Work(models.Model):
user = models.CharField(_("User"), max_length = 50, default = None)
intern = models.ForeignKey("Intern", default = 1)
date = models.DateField(_("Date"), default= timezone.now().today(), blank=True)
time_in = models.TimeField(_("Time In"),default= timezone.now().time(), blank=True)
time_out = models.TimeField(_("Time Out"),default= timezone.now().time(), blank=True)
I have tried timezone.now().time and datetime.datetime.now().time() and none of these work
When I try to run migrate on the server I get this error log
Apply all migrations: admin, auth, clockin, contenttypes, database, sessions, watson
Running migrations:
Applying clockin.0006_auto_20170523_1101...System check identified some issues:

For me this seemed to be an issue with mySQL that I was using as my database. I solved this by moving to the default sqlLite file.

Django migrations: TypeError: db_type() takes exactly 1 argument (2 given)

So I am trying to integrate my legacy postgresql to django. I have successfully created my models following this:
https://docs.djangoproject.com/en/1.11/howto/legacy-databases/
However when I add something to my models and try to migrate I get the following error:

The initial migration file:

Edit:
The problem is gone but i am not sure what fixed it. I basically deleted migrtions and tried from the start. On the way, it was fixed somehow. I am going to leave question unanswered so maybe someone will have a more compact answer.

Django migrations mixed up with 'PROTECT' and 'CASCADE'

I am stuck with migrations in django. I have two really basic models that will not migrate:
from django.db import models
# Create your models here.
class Instanz(models.Model):
type = models.CharField(max_length=30)
angelegt_am = models.DateField(auto_now_add=True)
class Person(models.Model):
instanz_fk = models.ForeignKey('Instanz', on_delete=models.CASCADE)
last_name = models.CharField(max_length=30)
first_name = models.CharField(max_length=30)
geburtsdatum = models.DateField()
It will raise the following exception. I dont get why it will search for a field named PROTECT. I used models.PROTECT in earlier migrations, before switching to CASCADE, but not any longer...

Here's the deal: I messed up some earlier migrations that were blocking the process, because Djangos migrate uses all unaplied migrations.
I had to go to the folder \\migrations and delete all files (except init.py of course).
Everything works like a charm now.
If this happens in production, you would probably delete only the migrations to the point of the last working migration...

Django: change a model and migrate?

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
Edit: console output
