I upgrade Django version from 1.11 to 3.2 and upgrade the installed python.
I am facing an error at this line
super().set_context(serializer_field)
Below is the Full class code.
class UniqueForProjectValidator(UniqueValidator):
def set_context(self, serializer_field):
super().set_context(serializer_field)
self.project = serializer_field.parent.context['project']
def filter_queryset(self, value, queryset):
queryset = queryset.filter(project=self.project)
return super().filter_queryset(value, queryset)
Here is the Error

It seems you have possibly upgraded Django Rest Framework as well however on Django Rest Frameworks GitHub page, the method set_context does not exist. So your error is telling you, the method set_context on the parent class UniqueValidator does not exist.
See their GitHub page here.

I have the following function that runs automatically with cronjob, it makes predictions based on an anomaly detection model and it saves the results to a postgres database:
def prediction_job():
"""
This job will run once every batch_minutes minutes to predict if the IPs appear in these batch_minutes minutes are normal or malicious
and save the results to postgres
"""
ip_estimator = IpStatePrediction()
predictions = ip_estimator.predict_ip_state()
predictions_dict_final = convert_dict_for_serializer(predictions)
serializer_result = PredictionsSerializer(data=predictions_dict_final)
if serializer_result.is_valid():
serializer_result.save()
else:
logger.debug("Error with data {}.".format(serializer_result.errors))
When I run it locally after running the commands python3 manage.py runserver and python3 migrate --database postgres, it saves the results to postgres.
However on production I am getting the following error, when the function is executed:

For me it looks like there are instabilities because undetected chromedriver maybe uses multiprocessing already, but isnt there any way where i can open multiple Browsers with UC and process each iteration parallel?

I have tried running heroku run python3 manage.py migrate and get No migrations to apply.
I deleted my migrations cache folder and also manually dropped a column from my Heroku postgres CLI to try and fix things but fear I only made it worse.
Here is the relevant models.py
class mapCafes(models.Model):
id = models.BigAutoField(primary_key=True)
cafe_name = models.CharField(max_length=200)
cafe_address = models.CharField(max_length=200)
cafe_long = models.FloatField()
cafe_lat = models.FloatField()
geolocation = models.PointField(geography=True, blank=True, null=True)
venue_type = models.CharField(max_length=200)
source = models.CharField(max_length=200)
cafe_image_url = models.CharField(max_length=200, null=False)
When I manually check the table through the Heroku DATABASE CLi the cafe_image_url column is not there - suggesting the migration isn't occurring correctly.
FWIW - everything works correctly on my local server.
I have to start using odoo 12 on my job but I can't start using it, I have already 5 days searching on google to find an answer.
I would be very grateful if you could please help me, with some of your wisdom :)
After I install odoo on my computer and visit localhost:8069 for first time it asks me to create my database but after I do this it doesn't load the login page instead it gives me an 500 internal server error with this console log every time I refresh the page:

Hi guys I was just following this tutorial (https://realpython.com/get-started-with-django-1/) to integrate a projects application for my Django portfolio-site project.
Everything was going well with the set up until I tried to log in to admin page of Django to add more objects to my Project model in the database.
After I click add, it return me an error page and it says like this:
Error return page [1]: https://i.stack.imgur.com/co1Cy.png

My models.py
from django.db import models
class Project(models.Model):
title = models.CharField(max_length=100)
description = models.TextField()
technology = models.CharField(max_length=20)
image = models.FilePathField(path='/projects/img/')
My file folder look like this
django-project
projects
static
projects
img
-project1.png
-project2.png
-project3.png
...
thanks for the help, I found the bug,
The FilePathField method accepts more explicit path than I thought it needed, so I replaced model with this, It worked like a charm now
from django.db import models
# Create your models here.
class Project(models.Model):
title = models.CharField(max_length=100)
description = models.TextField()
technology = models.CharField(max_length=20)
image = models.FilePathField(path='projects/static/projects/img/')
def __str__(self):
return self.title```
In model Project image field:
Should be project/img not projects/img
