'>' not supported between instances of 'decimal.Decimal' and 'QuerySet' How do you cange a QuerySet to a decimal or get access to the values in it?
I am trying to make an e-commerce site (CS50 Project 2) that allows the user to make a bid if their bid is greater than or equal to the listing price and greater than all other bids. I have been able to check if the bid is greater than the listing price but need help checking if it is greater than the other bids. I am receiving this error message.

Why is Django questionnaire app not recognizing answer choices after deploying with Apache and MySQL?
I am currently trying to deploy my Django project through Apache and MySQL. All of my project apps are working well except for my questionnaires app. I am not able to record responses in the database and getting an error that says [{'id': ['Select a valid choice. That choice is not one of the available choices.']}]. I am confused because this app was working well when I was running my project through my local server and Django's default SQLite database. There are two questionnaires in my app: one is a mood board where the user selects a picture that best represents how they are feeling (I am not trying to record the actual image, just the name of the image), and the second is the Edinburg Postnatal Depression Scale, it is a multiple-choice survey that has no pictures. Can someone please give me advice as to why the app is not recognizing the answer choices? Here is my models file: User = settings.AUTH_USER_MODEL class Questionnaire(models.Model): name = models.CharField(max_length=255) text = models.CharField(max_length=200) def __str__(self): return self.name class Question(models.Model): text = models.CharField(max_length=200) questionnaire = models.ForeignKey(Questionnaire, on_delete=models.CASCADE, related_name='questions') def __str__(self): return self.text class Answer(models.Model): question = models.ForeignKey(Question, models.SET_NULL, blank=True, null=True, related_name='answerlist') questionnaire = … -

Understanding CORS cookies
I have been trying for some time to deploy a web application i built, using reactjs for the Frontend and Django for the backend. After struggling with django configurations i managed to make the sessions work when both FE and BE are running locally, so the next step was deploying the BE on a remote host and i chose Heroku, with a docker setup, while i kept the FE running locally to test the BE deployment. This completely broke the django sessions i relied upon, as the BE was sending the relevant cookie to FE, but the FE was not including it in the next request, making it completely useless (include credentials did not solve the issue). After trying to mess with every CORS configuration on the Server side,(cors-headers) i came to the conclusion that browsers simply don't allow these cross-domain cookies. Meaning the FE can receive the Cross-domain cookie from the BE, but no matter what it will not include it in the next request. This leads me to 2 questions: Is my understanding of the issue correct? Meaning it really can't be done with cross-domain BE an FE? If so, is the only approach having FE and BE … -

I can't find a host for my python and django website
I've created a website using Django framework. I have HTML CSS Python and SQL. I was able to put python into my index.html thanks to : https://docs.djangoproject.com/en/4.0/ref/templates/language/#variables Regarding python I have a script.py that generates a list of numbers L = [120, 140.65, etc] This script updates every 10 minutes because the numbers change L = [122.2, 140.85, etc] Then this list is imported into MySQL. So the DB changes every 10 minutes. Finally, a table is generated on my site using index.html and css with the updated numbers every 10 minutes. My website : --index.html --style.css --script.py --MySQL database The problem is, how can I find a website host who will automatically run my script.py (which will update my website every 10 minutes), which will understand python in html (this: {% for x in story_list %} ) and which will host my database. Thank you for your help! : Sorry for my bad english -

Django ORM: filtering on concatinated fields
In my app, I have a document number which consists of several fields of Document model like: {{doc_code}}{{doc_num}}-{{doc_year}} doc_num is an integer in the model, but for the user, it is a five digits string, where empty spaces are filled by zero, like 00024, or 00573. doc_year is a date field in the model, but in full document number, it is the two last digits of the year. So for users, the document number is for example - TR123.00043-22. I want to implement searching on the documents list page. One approach is to autogenerate the full_number field from doc_code, doc_num and doc_year fields in the save method of Document model and filter on this full_number. Anothe is to use Concat function before using of filter on query. First by concatinate full_code field docs = Document.annotate(full_code=Concat('doc_code', 'doc_num', Value('-'), 'doc_year', output_field=CharField())) and than filter by full_code field docs = docs.filter(full_code__icontain=keyword) But how to pass doc_num as five digits string and doc_year as two last digits of year to Concat function? Or what could be a better solution for this task? -

What is the right way to set up Gunicorn on my Django app?
everyone! Could you please help me with setting up Gunicorn for Django application. I'm going through clear and great digital ocean tutorial and don't know how to access my wsgi.py file for Gunicorn.

Django image saving

I want to save only the resized image. As far as I know the super save method here additionally saves the original image to database. But I want it to save only resized to prevent data overflow.

Sync on-premises folder with website's static folder in AWS
I have a Django web app deployed with AWS elastic beanstalk. It’s basically a website. The site reads data from a postgres db, combines it with some images located inside a static folder, and gives an outcome according to my needs. It works fine manually but my intention from the beginning was to make it renew its content automatically. Thus, I need to do two things: To upload the data from a csv file periodically (I’m doing it currently through an input form). And more importantly, to sync my on-premises windows server folder where the images are stored, with the above-mentioned static folder. I’m new to Django and web development in general, and my knowledge over cloud services is still limited, so I would appreciate a small guidance. My primary question is if such a thing exists and if it’s something common or at least possible, and secondly how to approach this and where to focus, in order not to waste time. Thanks in advance! -
