How to fix model error when upgrading module in odoo 13

I get this error when I try to upgrade my custom module in odoo 13.

This is the sales.terms model

_description = 'Terms and Conditions'
_rec_name = 'typex'
new_type = fields.Selection([
('accessories', 'Accessories'),
('glass', 'Glass Work'),
('aluminium', 'Aluminium profiles'),
('projects', 'Projects')
], string='Testing')
d_active = fields.Boolean(string='Active')
notes = fields.Text()
I have a new model named 'sales.terms' I created and I created the corresponding ir.model.access.csv file for it, so I traced down the error and discovered that it isn't the whole model giving causing the error but just the selection field, if i remove the selection field the module upgrades fine.
I am confused as to what might be wrong.

I think there is something missing
class SalesTermsAndConditions(models.Model):
_name = 'sales.terms'
_description = 'Terms and Conditions'
_rec_name = 'typex'
new_type = fields.Selection([
('test', 'Test'),
('atest', 'A test'), // Comma is missing
('accessories', 'Accessories'),
('glass', 'Glass Work'),
('aluminium', 'Aluminium profiles'),
('projects', 'Projects')
], string='Testing')
d_active = fields.Boolean(string='Active')
notes = fields.Text()

Try to remove _rec_name.Replace with some field.
_rec_name = "new_type"

The selection seem to be ok. if you rename new_type does it then upgrade?
Can you look first errors wen you boot odoo or reload modules

psycopg2.ProgrammingError: column "data" of relation "WorldBank_projects" does not exist

I'm working on a Django application which fetches JSON data from an API and stores it in PostgreSQL database. But while migrating the app I'm getting these errors:
psycopg2.ProgrammingError: column "data" of relation "WorldBank_projects" does not exist

What should I change in code to resolve this error?

django - factory_boy AttributeError: 'NoneType' object has no attribute '_meta'

I'm writing unit tests for my Django REST Framework app and I'm creating my fake testing data using factory_boy. I've come across the following error message when I try to run my tests

AttributeError: 'NoneType' object has no attribute '_meta'
I pretty much have no clue what's going on since my understanding of backend structure isn't great. Here's the factories:
class UserFactory(factory.DjangoModelFactory):
class Meta:
model = User
class ConferenceFactory(factory.DjangoModelFactory):
class Meta:
model = Conference
class ApprovalFactory(factory.DjangoModelFactory):
class Meta:
model = approvalModels.Approval
class SubmissionFactory(factory.DjangoModelFactory):
class Meta:
model = submissionModels.Submission
And here's where I call them:
def setUp(self):
self.user1 = UserFactory(
username = 'Leo',
id = '99'
)
self.user2 = UserFactory(
username = 'LeoLeo'
)
self.conference = ConferenceFactory(
admin = self.user1
)
self.submission1 = SubmissionFactory(
conference = self.conference,
contributor = UserFactory()
)
self.submission2 = SubmissionFactory(
conference = self.conference,
contributor = UserFactory()
)
If you look through the error message, it's specifically complaining about contributor = UserFactory()
Let me know if there's an easy fix, or even some explanation of what's going on would be nice.
Thanks so much!
Here's the file:
tests.py

You need to add correct relations (SubFactory) in the factory definition first.

DateTimeObject not being accepted by Django Model (that expects it)

In my models.py I have the following model:
from django.contrib.auth.models import User
class Notification(models.Model):
recipient = models.OneToOneField(User)
timestamp = models.DateTimeField()
In views.py, I try to create an instance of this model via Notification.objects.create(recipient = self.request.user, timestamp=timestamp) where self.request.user is an instance of User, and timestamp equals [datetime.datetime(2015, 10, 19, 16, 3, 2, 356585, tzinfo=<UTC>)]. Yet for these values, when the objects.create command is run, I get an error: Type error: expected string or buffer.
The line number happens to be the objects.create command. I suspect my datetime object is misconfigured. The whole trace is as follows:

TypeError: expected string or buffer
Stumped about what to do here! I'm using Django 1.5 and Python 2.7.

Timestamp appears to be a list with one datetime in it. It should be a datetime, for example timestamp[0]. It could also be a correctly-formatted string - that's the code path the exception you're seeing comes from, but it fails because the value passed in is a list rather than a string.

DatabaseError: This query is not supported by the database.
Here are my models that matter for this problem:
class ChallengeAct(models.Model):
challenge = models.ForeignKey(Challenge, blank=True, null=True)
user = models.ForeignKey(User, blank=True, null=True)
start_date = models.DateTimeField(blank=True, null=True)
progress_value = models.IntegerField(default=0)
earned_coupon = models.ForeignKey(EarnedCoupon, blank=True, null=True)
Here is the method that causes the error:
def foo_bar(request):
user = request.user
c = ChallengeAct()
c.challenge = Challenge.objects.get(id=1)
c.start_date = datetime.now()
c.progress_value = 1
c.user = user
c.save()
# Here is where I set the user to null to avoid the DatabaseError
c.user = None
return [c]
The interesting thing is that I need to set the c.user = None right before I return it so I don't get the DatabaseError: This query is not supported by the database. problem.
--update-- The more I think about it, it seems like a pyamf and django-nonrel problem with getting the user object. I'm guessing that when pyamf tries to get the user object it is using some type of join query, which isn't supported on django-nonrel.
Why is this? Is there a way around it?

You should not have to to allow for blank=True, null=True for User model. Normally django.contrib.auth.models.AnonymousUser takes care of anonymous requests. It may or may not fix the issue, but it is worth trying, i.e.:
class ChallengeAct(RewardActBase):
user = models.ForeignKey(User)
....
