Django's AttributeError for PointField()
I have a problem with my Django database. When I enter: python manage.py makemigrations. I got this exception: AttributeError: module 'django.db.models' has no attribute 'PointField'. Here is my very simple code that cause the issue: from django.db import models import uuid # Create your models here. class Image(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4,editable=False) location = models.PointField() # The culprit date = models.DateTimeField() image = models.ImageField() Thank you in advance. It supposed to make changes to my PostgreSQL database. Well the database hasn't been made yet, I already initialize it with SQLite WITHOUT THE CODE ABOVE. IT WAS INITIALIZED BEFORE THERE IS ANYTHING IN THE MODELS FILES, trying to switch to PostgreSQL. -
How to create a Postgresql database query in Django with BitXor bitwise comparison and filtering by Hamming distance value?
My task is to develop a function for searching images in a database using perseptual hash and Hamming distance comparison. The code below works, but due to the fact that filtering occurs in the Django environment and Python, the code runs extremely slowly, on average the execution time is more than 7 seconds with 1,500,000 records in the database, but the number of records on the production server will be much larger and the request processing speed will drop even more. models.py # models.py from django.db import models class Fids(models.Model): """ The model stores records with computed image hashes (>6000000 records) picture = 'https://ae01.alicdn.com/kf/Sc835208f704548b7b230fd12f72850bfU.jpg' hs8 = '9aca3edfc0c23538' bin8 = '1001101011001010001111101101111111000000110000100011010100111000' """ picture = models.URLField() hs8 = models.CharField(max_length=50) bin8 = models.CharField(max_length=64) service.py # service.py import requests import json import imagehash from PIL import Image from main.models import Fids def hamming_distance(binary_str1, binary_str2): """ The function calculates the Hamming distance example input: binary_str1 = '1001101011001010001111101101111111000000110000100011010100111000' binary_str2 = '1001101011001010001111101101111111000000110000100011010100111000' """ if len(binary_str1) != len(binary_str2): return -1 xor_result = int(binary_str1, 2) ^ int(binary_str2, 2) hamming_distance = bin(xor_result).count('1') return hamming_distance def search(url=None, hamming=None): """ Search query processing function example input: url = 'https://ae01.alicdn.com/kf/Sc835208f704548b7b230fd12f72850bfU.jpg' hamming = 8 output: delay: 8-15 sec """ if url is None: return … -

Do Docker volumes also update the Source application?
I am going insane for the following. I have been following youtube tutorials by two different makers and in both cases, they start with a fresh directory where there is nothing but a virtual environment. Then they add the 3 expected files Dockerfile, docker-compose.yml and the requirements. txt. Like them I get to create the container and launch it to see the django app successfully created. BUT, here is where the problem comes. Once they either stop or delete the container and they get back to the terminal prompt, that is, once they are at the OS source application and not the container, both of them can do python manage.py runserver and launch the development server, or they can migrate, but when I click on the requirements.txt on the project tree, I get a notice that Django has not been installed. I can understand that because we actually installed Django in the container but not in the source application. I know that volumes are suppose to update the container if you make changes in the application source in your IDE, but not the other way around. That is why django is not installed. Here are the files: Dockerfile: FROM python:3.8 … -
Render video from js into html
I'm new here and have a question. How can I render the webcam video from JavaScript into HTML? I want to scan QR-Codes in my browser and while scanning there should be the video from the camera for better user experience (easier to find the qr-code). For scanning the QR-Codes, I use Instascan. My code looks something like this: HTML: <div class="video-container"> <div class="overlay-box"> <video id="preview"></video> </div> </div> JavaScript: let scanner = new Instascan.Scanner({ video: document.getElementById('preview') }); // When starting scanning, activate via css document.getElementById("preview").style.display = "block"; // When stopping scanning, deactivate via css document.getElementById("preview").style.display = "none"; I tried without the css stuff, but that was not a problem. It should be a problem with the scanner ig... Expecting: that it render it into the html file that I can see the camera output while scanning Thanks for every help!

Getting a script to run after files have been uploaded by users
I have a django project and I would like to trigger a script for every 30 items that get uploaded by users. Basically, after 30 items have been uploaded by users, the script checks the latest (i.e. last) item which has been uploaded by a user, and if there is a problem with the item it then gives a warning to the user. After 30 more items get uploaded by users the process repeats. The problem is I'm not sure how to do this since I'm new to django and I can't find any documentation for it, so if anyone has any ideas I would greatly appreciate it. Thank you! -

Create a queryset that automatically queries onetoone objects
I'm building a django application that has a model with multiple OneToOne relationships: class MyApp(BaseModel): site_1 = models.OneToOneField( Site, on_delete=models.CASCADE, related_name="site1", null=True ) site_2 = models.OneToOneField( Site, on_delete=models.CASCADE, related_name="site2", null=True ) site_3 = models.OneToOneField( Site, on_delete=models.CASCADE, related_name="site3", null=True ) def __str__(self): return self.title class Meta: verbose_name = "Main Application" verbose_name_plural = "Main Application" When I create a queryset using MyApp.objects.all() it returns an object with just the primary keys: { "model": "mesoamerica.mesoamericaapp", "pk": 1, "fields": { "site_1": 1, "site_2": 2, "site_3": 3 } However, I'd like to create a queryset that grabs each of the Site models by pk and attaches them to the query, rather than having to do that myself.

django view that combines model data with all fields from its parent
I'm creating a django app where I have a model with a parent class: class BaseModel(models.Model): modified_date = models.DateTimeField(auto_now=True) class Meta: abstract = True class Site(BaseModel): name = models.CharField( max_length=25, verbose_name="Site Name (Internal) (25 char)", null=True ) and I've created a view to return the object as JSON. However, when I query and get the objects with Site.objects.all(), it doesn't contain the data from its parent class -- just the data from its own model. Now, I can go ahead and grab the primary keys and manually query the two datasets and consolidate them, but I bet there has to be a django / pythonic way to do this in a single query. prefetch_related() and select_related() dont seem to do what I want, or at least I havent figured out how to make them work for me.

I'm having an issues starting using jupyter on my system (Mac OSX 14.2.1) even on new django projects. django-admin startproject mysite cd mysite/ pip install virtualenv virtualenv --python=$(pyenv root)/versions/3.9.18/bin/python3 env pip install jupyter ipython django-extensions # add django_extensions to INSTALLED_APPS vim mysite/settings python manage.py shell_plus --notebook Running the above has the following error: $ python manage.py shell_plus --notebook Traceback (most recent call last): File "/path/to/project/mysite/env/lib/python3.9/site-packages/django_extensions/management/commands/shell_plus.py", line 281, in get_notebook from notebook.notebookapp import NotebookApp ModuleNotFoundError: No module named 'notebook.notebookapp' CommandError: Could not load shell runner: 'IPython Notebook'. I have a feeling the answer is something really straightforward, but I've been stuck on this for weeks now and haven't gotten to the bottom of it. -

Django save post via celery
I have a particular use case where i write text for a blog post in admin dashboard. Then i want to generate the embeddings of post. I am doing this in admin.py @admin.register(Post) class PostAdmin(admin.ModelAdmin): list_display = ('title', 'author', 'created_at') readonly_fields = ('embeddings_calculated','emebddings_updated_at') def save_model(self, request, obj, form, change): if not obj.meta_title: obj.meta_title = obj.title obj.meta_description = obj.content[:160] super().save_model(request, obj, form, change) print("django post id",obj.id) post = get_object_or_404(Post, id=obj.id) print("django post title",post) if not change: # if new post not an edit post task_id = perform_task.delay(obj.id) result = AsyncResult(str(task_id), app=app) print("AsyncResultx", result) print("AsyncResultx_state", result.state) here is my celery task @shared_task() def perform_task(post_id): print("celery post id",post_id) post = get_object_or_404(Post, id=post_id) print("celery post title",post) I am getting this error django.http.response.Http404: No Post matches the given query. Though the print statement such as django post id and django post title show me correct result. But the issue lies in celery. I cant see celery post title in console. I aslo tried task_id = transaction.on_commit(lambda: perform_task.delay(obj.id)) But it did not work as well. Without celery every thing work well, but i want to use celery.
