Django: Updating Old Migration Files that Have `django_mysql.models.JSONField`?
In older versions of Django, you could use JSON fields in models via django_mysql.models.JSONField. In new versions of Django, JSONField is no longer in django_mysql.models. I've updated my models.py files accordingly, but I still have old migrations files that look like this: # Generated by Django 2.1.7 on 2019-07-17 22:59 from django.db import migrations import django_mysql.models class Migration(migrations.Migration): dependencies = [ ('rss', '0009_delete_patternmatchingkeywords'), ] operations = [ migrations.AddField( model_name='rssoutput', name='industries', field=django_mysql.models.JSONField(default=list), ##<== ERROR ), ] Now when I run makeMigration, I get this error: AttributeError: module 'django_mysql.models' has no attribute 'JSONField' What is the correct procedure to address this? I'm using: Django 4.0 Python 3.9.13 django-mysql 4.7.0 -

Am wondering how i can get this html code into a forms.py in my ReviewForm as widgets. This code: 'rating': forms.Select(attrs={'class': 'form-control',}), Should be as the html code under with 1-5.

How to edit/change a field in a model without using a form in django
So im creating a Multiple choice quiz and I want to be able to add different quizzes with different difficulty and have around 20 questions for each quiz that i make. From those 20 questions the program should randomly select 10 questions and displays them SEPERATELY. So basically I got the questions to display seperately and created a few models but i also want to save the users results after they have answered the 10 questions to the database and how many times they attempted the same quiz. Is there a way to do this without using a form? models.py from django.db import models from django.contrib.auth.models import User class Quizzes(models.Model): CHOICES = ( ('Easy', 'Easy'), ('Medium', 'Medium'), ('Hard', 'Hard'), ) name = models.CharField(max_length=200) quizDesc = models.TextField() difficulty = models.CharField(max_length=200, null=True, choices=CHOICES) class Meta: verbose_name_plural = "Quizzes" def __str__(self): return self.name class QuestionList(models.Model): quiz = models.ForeignKey(Quizzes, on_delete=models.CASCADE) questNum = models.IntegerField(null=True) question = models.CharField(max_length=200,null=True) op1 = models.CharField(max_length=200,null=True) op2 = models.CharField(max_length=200,null=True) op3 = models.CharField(max_length=200,null=True) op4 = models.CharField(max_length=200,null=True) ans = models.CharField(max_length=200,null=True) class userQuizInfo(models.Model): username = models.ForeignKey(User, on_delete=models.CASCADE,null=True) quiz = models.ForeignKey(Quizzes, on_delete=models.CASCADE,null=True) correct = models.IntegerField(null=True) wrong = models.IntegerField(null=True) questOrder = models.CharField(max_length=10,null=True) views.py questions = list(QuestionList.objects.filter(quiz_id=pk)) questions = random.sample(questions,1) # userInfo = userQuizInfo.objects(pk=pk) # userInfo.questOrder += … -
Is there a way to EDIT databases (sqlite) in VSCode?
I am currently trying toed the database that comes with Django. Im tryin to use the VSCode Extension vscode-sqlite to edit the database. While I currently am able to look at the database without the gibberish that shows up when I try to open the database in a text editor, I can't find a way to actually edit the database. I think the buttons on the upper right corner of the UI might have something to do with whatever Im trying to achieve, but I dont really know what they do. Any help would really be appreciated. the unexplained buttons -

How to use Django variable in JavaScript /jQuery?
I am passing a list of name subject in my HTML template from views.py but it's not working the way its working when I pass a list statically. Also, It's by default converting into Unicode (that I don't want) Following is my code, var data = "{{subject}}"; console.log("data before for loop",data) var i; for (i = 0; i<data.length; i++) { data = data.replace("&#39;", "'"); } console.log("data after for loop",data) var t2 = ['IT', 'Maths', 'History', 'Civics', 'Virtualization', 'BIO', 'EH', 'Chemistry']; console.log(typeof data); console.log(typeof t2) and following is the output of console.log, data before for loop [&#39;IT&#39;, &#39;Maths&#39;, &#39;History&#39;, &#39;Civics&#39;, &#39;VWE&#39;, &#39;BIO&#39;, &#39;EH&#39;, &#39;EHas&#39;] data after for loop ['IT', 'Maths', 'History', 'Civics', 'VWE', 'BIO', 'EH', 'EHas'] string object I want to know why it's not working.. and how can I make it work..

Access Django M2M values in queryset without looping
I receive some data through Ajax that allows me to do some filtering on a model that has some m2m relations (say Model). I get a queryset, say "content" that I then need to send back using json. Here are simplified lines of code: content = Models.objects.all() content = content.values return JsonResponse({"data":list(content)}) It was working fine but the project changed and I now need to include the values of some of the m2m related models attached to Model to each queryset result instances, problem is that content=Model.objects.all() will of course not give me these values without some looping so I am stuck. I remember using a depth option in DRF that would have done the job here but unfortunately I cannot do this now as the project is too advanced and live. Any way to add directly in the queryset the results of the m2m related values ? Many many thanks -
How to add custom permissions to Django admin Groups page?
I want to create a Group that contains multiple custom permissions related to a custom Account model (extended from base User), then restrict access to routes/pages to Accounts only within that group. I have added the following custom permissions to my Account model (which is a working extension of the base AUTH_USER_MODEL)... class Account(models.Model): date_created = models.DateTimeField(auto_now_add=True, verbose_name='Date Created') date_modified = models.DateTimeField(auto_now=True) user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.PROTECT) class Meta: permissions = ( ("can_access_x_pages", "To provide access to X pages"), ("can_access_y_pages", "To provide access to Y pages"), ("can_access_z_pages", "To provide access to Z pages"), ) ... but those permissions do not show up on the "New Group" page on Django Admin: Based on this GeeksForGeeks article, once the permissions have been added, they should simply be displayed. Any idea what I am missing? This self-answered StackOverflow question from 2016 is the same issue, but that OP cited a bug in django-admin-view-permission as the problem, but that is all they wrote. Edit: I checked my Adminer view of the database, and I do not see the new permissions there, so I'm guessing that they have not been migrated? -
Django channels unable to connect(find) websocket after docker-compose of project using redis
I have currently implemented websocket connections via django channels using a redis layer. I'm new to docker and not sure where I might have made a mistake. After the docker-compose up -d --build the "static files, media, database and gunicorn wsgi" all function, but redis won't connect. even though it is running in the background. Before trying to containerize the application with docker, it worked well with: python manage.py runserver with the following settings.py setction for the redis layer: CHANNEL_LAYERS = { "default": { "BACKEND": "channels_redis.core.RedisChannelLayer", "CONFIG": { "hosts": [("0.0.0.0", 6379)], }, }, } and by calling a docker container for the redis layer: docker run -p 6379:6379 -d redis:5 But after the trying to containerize the entire application it was unable to find the websocket The new setup for the docker-compose is as follows: version: '3.10' services: web: container_name: web build: context: ./app dockerfile: Dockerfile command: bash -c "gunicorn core.wsgi:application --bind 0.0.0.0:8000" volumes: - ./app/:/usr/src/app/ - static_volume:/usr/src/app/staticfiles/ - media_volume:/usr/src/app/media/ ports: - 8000:8000 env_file: - ./.env.dev depends_on: - db networks: - app_network redis: container_name: redis image: redis:5 ports: - 6379:6379 networks: - app_network restart: on-failure db: container_name: db image: postgres volumes: - postgres_data:/var/lib/postgresql/data/ environment: - ./.env.psql ports: - 5432:5432 networks: … -
Django pytest running many migrations after tests
I am running pytest-django with a legacy database that was not created by Django (e.g. all my models use managed=False). In production, everything is fine but in testing Django wants to apply a bunch of curious migrations. For testing, I have a pre-populated test database and I want my tests to commit changes to the database (because we have logic in db views and triggers that needs to get run). All that is working fine but afterwards a ton of migrations are run and it takes my test suite time from 1s to 70s. The migrations are overwhelmingly this type: ALTER TABLE [DeprecatedLegacyTable] CHECK CONSTRAINT [FK_dbo.DeprecatedLegacyTable_dbo.User_DeprecatedServiceId]. The tables aren't even in any models.py, so I guess Django is digging this up with inspectdb. I've looked around a bit and it seems this is a "feature" of Django but it is hurting my workflow. Is there any way to apply these migrations once and for all rather than replay them every test run? (I'm also pretty curious why these migrations are all being done after the tests themselves. Seems backwards.) -
Django can't find admin page
I'm building a blog app in Django and I wanted to access the build-in admin page. However, when I try to reach it, it keeps throwing a 404 error and I have no idea why. So, when I try to access http://127.0.0.1:8000/admin/ I get: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/admin/ Using the URLconf defined in blog.urls, Django tried these URL patterns, in this order: [name='index'] posts [name='posts'] posts/<slug:slug> [name='post'] The current path, admin/, didn’t match any of these. You’re seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. Note: The porject is called 'my_site' and the app is called 'blog' Some code snippets below: my_site/urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('blog.urls')) ] blog/urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), path('posts', views.posts, name='posts'), path('posts/<slug:slug>', views.post, name='post'), ] blog/views.py from django.shortcuts import render, get_object_or_404 from .models import Author, Post # Create your views here. def index(request): all_posts = Post.objects.all().order_by("-date") latest_posts = all_posts[:3] return render(request, "blog/index.html", { "posts": latest_posts }) def posts(request): return render(request, … -
How to build MS Access like form in Python?
How would you go about building a form like the one attached in Python and having each metric/cell being filled in? For example, I enter someone's name and the other fields would get filled in with data from various tables. It's currently built in Excel and it's calling the data from multiple tabs but I'd like to transition to Python. I have built the backend data portion of it in Jupyter Notebook using Pandas but now would like to build the shell so that the data will auto-populate in its designated cell/location once a given variable has been entered into an input field (like 'Name' in the example). Can I do this in Jupyter Notebook (preferred)? Would I have to learn/use Django, Flask or HTML? Any tips, suggestions, or examples that you've seen would be greatly appreciated! Form Example -

Django Rest Framework: why is my api call much slower in production than dev?
I've a django app that's deployed on an ec2 instance with docker and nginx. An api call that takes 700ms on my local system takes 15s on the production server. Even with debug set to false, on my local machine the call returns within 600-800ms but on production it consistently takes 15-20s to return. What causes this difference in performance? How does the way django handles api calls in debug differ from prod? I already use select_related and prefetch wherever possible. What changes could I make to speed up the api calls on the prod env? -

To that end, I have been trying to create a queryset join of a set of models (as shown below): models.py class ModeOfTransport(models.Model): mode_of_transport = models.CharField(unique=True, max_length=4... class Route(models.Model): route_id = models.AutoField(primary_key=True) route_start = models.ForeignKey(City, related_name='route_start') route_end = models.ForeignKey(City, related_name='route_end') class RouteLeg(models.Model): route_leg_id = models.AutoField(primary_key=True) route_id = models.ForeignKey(Route, related_name='route_hdr') leg_start = models.ForeignKey(City, related_name='leg_start') leg_end = models.ForeignKey(City, related_name='leg_start') mode_of_tptn = models.ForeignKey(ModeOfTransport, related_name='route_tptn_mode') class ImageType(models.Model): image_type_id = models.CharField(primary_key=True, max_length=1) image_type = models.CharField(max_length=4) class RouteImage(models.Model): image_id = models.AutoField(primary_key=True) image_name = models.CharField(max_length=125) image_type = models.ForeignKey(ImageType) image_route = models.ImageField(upload_to='images/route_images/') From a list of existing routes (a generic listview), I am trying to create a further drilldown like this: views.py def graf_display_route(request, pk): if request.method == 'GET': route_grafiks = RouteLeg.objects.all().filter(route_id=pk) return render(request, 'route_grafiks.html', {'route_grafiks': route_grafiks}) Now in order to get to the image field (RouteImage.image_route), I tried the following to get the image_type and then the image itself: qs_mode_of_tptn = ImageType.objects.filter(image_type_id__in= route_graphics.values_list('mode_of_tptn', flat=True)) The result (on printing the list of resultant queryset) I can see in the terminal as: [<ImageType: ImageType object (2)>, <ImageType: ImageType object (3)>]> Next, using the queryset qs_mode_of_tptn when I use another qset, I get the image table fields … -
How do I test all of my app's urls in Django to make sure they require authentication?
I want to write a Django test that looks at all the urls in one particular app, and makes sure that hitting them without being authenticated redirects me to the login page. Something like: from django.test import TestCase from django.urls import reverse from my_app.urls import urlpatterns class AuthTest(TestCase): def _test_url(self, url): response = self.client.get(url) self.assertRedirects(response, expected_url=reverse("login_app:login")+ "?next=" + url) def test_auth(self): for url in urlpatterns.SOMETHING: with self.subTest(url=url): self._test_url(url) Is there a way to get the actual list of urls in each urlpattern for my app? And, related question: for those URLs that require a pk, is there a way to automatically use pk=1? My fixtures will make sure that pk=1 exists for all those urls. -
