How to optimize SQL in tree-like comment structure django?
I have posts with tree comments in it. Comments have likes as well. I've managed to optimize SQL queries that usual comments, related to the post itself, don't create new queries, but answers to the other comments still create 3-4 new requests to the data base. Can I somehow reduce number of queries? I've been using prefetch_related for this purpose.

Restrict access to multiple admin sites per user/group in Django
When using multiple admin sites in Django i want to seperate the depth / complexity of information availabe in different sites. The generally works but a user can still login to the other sites and see more than he is supposed to because he has view permission to a model. Imanine having morve levels between staff and superuser like "is_staff_trainee", "is_staff_junior", "is_staff_senior" and "is_staff_bigboss". They all have their own admin sites. On some models the admin is the same for all of them, so i register the same ModelAdmin to all of the sites. But on some model, let's say "Drinks", they all get their own DrinkAdminTrainee, DrinkAdminJunior, DrinkAdminBigBoss, you get it. A Trainee has most of the fields read only, a Junior can edit most of them on the edit page, a senior gets additional information about e.g. the price calculation an can choose from more expensive ingredients to create his drinks and the Big Boss can also see all the old (long deactivated) Drinks from the Past. That works perfectly. But any Trainee can still login to the Big Boss Admin site if he kows the URL and also use it because he still "is_staff" and has view … -
Lock editing page in django
i have a single page application and a django server with the django rest framework. As an example, I have a resource called House. User 1 is on the /houses/5/edit page and is currently editing the house with ID 5. Now I want to block editing from the house with ID 5 for other users. Only one user should be able to access the editing page of a particular house at a time. All other users should see on the detail page of the house with ID 5 (/houses/5/) that the house is already being edited. Only when user 1 leaves the page /houses/5/edit, another user should be able to edit the house. I want to have this blocking mechanism because otherwise changes to the house could be overwritten by another user. So the mechanism should be similar to the blocking mechanism in Wordpress CMS for blocking a page or post. How can I implement this? I already use django-channels for push notifications. My idea was to use websockets for blocking. Also, I saw that django-redis offers a blocking mechanism. However, I still have no idea how to implement my requirements with it and whether these technologies are the best … -
Understanding and setting the order of Django migrations
I have models that look like: class FubarCategory(models.Model): class name = models.CharField(max_length=32) class FubarScenarioType(models.Model): class name = models.CharField(max_length=32) class FubarProduct(models.Model) category = models.ForeignKey( FubarCategory, on_delete=models.DO_NOTHING, related_name="products" ) scenario = models.ForeignKey( FubarScenarioType, on_delete=models.DO_NOTHING, related_name="products" ) class FubarTransaction(models.Model): product = models.ForeignKey( FubarProduct, on_delete=models.DO_NOTHING, related_name="transactions" ) I expect a brand new migration to look like: Migrations for 'fubar': apps/fubar/migrations/0001_initial.py - Create model FubarCategory - Create model FubarScenarioType - Create model FubarProduct - Create model FubarTransaction Instead, I see this: Migrations for 'fubar': apps/fubar/migrations/0001_initial.py - Create model FubarCategory - Create model FubarProduct - Create model FubarScenarioType - Add field scenario_type to Fubarproduct - Create model FubarTransaction Why is FubarScenarioType being created after FubarProduct instead of before? -
How to authenticate selenium before running `pytest`?
I'm using pytest-django with selenium for testing features. Some features require being logged in. Here's how I create a test user: import sqlite3 import uuid import pytest from django.conf import settings from django.contrib.auth.models import User from django.core.management import call_command from selenium.webdriver import Chrome, ChromeOptions @pytest.fixture(scope='session', autouse=True) def browser(): options = ChromeOptions() options.add_argument('--no-sandbox') options.add_argument('headless') chrome = Chrome(options=options) yield chrome chrome.close() @pytest.fixture(scope='session') def test_user(): return {'username': uuid.uuid4().hex[:10], 'password': uuid.uuid4().hex} @pytest.fixture(scope='session') def django_db_setup(django_db_blocker, test_user): db_path = settings.BASE_DIR / 'test-db.sqlite3' sqlite3.connect(db_name := db_path.as_posix()) settings.DATABASES['default']['NAME'] = db_name with django_db_blocker.unblock(): call_command('migrate', '--noinput') User.objects.create_user( username=test_user['username'], password=test_user['password'], email=f'{test_user["username"]}@test', ) Now that a test user is created, I need to use it with selenium before tests that require logging in. A typical test class looks like: class TestSomeUrl: def test_feature1(browser): ... def test_feature2(browser): ... But I need to login first. What would be the proper way to do so? I tried first to login inside the browser fixture by doing: @pytest.fixture(scope='session', autouse=True) def browser(live_server, test_user): options = ChromeOptions() options.add_argument('--no-sandbox') options.add_argument('headless') chrome = Chrome(options=options) chrome.get(f'{live_server}/login') browser_login(chrome, test_user) yield chrome chrome.close() But I get a Bad Request (400) because live_server seemingly has no started yet, otherwise it should get f'{live_server}/login' without issues.

How can I pass an attribute value inside a StructBlock in Wagtail 4.1?
I am trying to create a StructBlock in Wagtail that contains a ChoiceBlock. The choices for this ChoiceBlock should be generated from an import that takes an id from a previous ModelChooserBlock value. However I am doing something wrong as I am unable to read the value from the ModelChooserBlock to be able to get it's id. Is there a way to get the value.id of the ModelChooserBlock and pass it back to the StructBlock to generate the choices? See my code: class StartListBlock(blocks.StructBlock): """ Display the start list for a specific race """ class Meta: template = 'blocks/startlist_block.html' icon = 'site' label = _('race_startlist') title = blocks.CharBlock( required=False, label=_("title"), ) # model id will be passed to import race choices race_day = ModelChooserBlock( target_model=RaceDay, label=_("race day"), ) race = blocks.ChoiceBlock( required=False, label=_('race'), choices=[], # choices will be generated outside the block ) I tried to create a new ChoiceBlock inside get_context and pass it back to the StructBlock with the new choices, but for the choices to show I needed to refresh the page and the selected race value did not get pass to the context. Please advise if this is not the correct approach and how it might … -

Django_eventstream to send notifications from backend to frontend: the stream is established but it's empty

Django does not translate variables loaded on init
When I define a constant in Django file that is loaded while the app is initiating, it does not translate the value when I change the language. Example: # widgets.py from django.translation import ugettext_lazy as _ MY_CONSTANT = _('some text') When I try to use MY_CONSTANT its value is translated to the default init language but not evaluated to the current language on demand. How could I fix this? -
I want any language translation functionality in my "Next.js(version 13) + Django" project. As react-google-translate does not support my tech version
The user wants to add language translation functionality to their project. The project is built using Next.js (version 13) and Django. The user has tried using react-google-translate but it doesn't support their tech version. They need an alternative solution for language translation. The user can consider using a Python package called "translate" to implement translation functionality. The package supports multiple languages and can be installed using pip. To use the package, the user can create an instance of the Translator class and specify the source and target languages. The translate() method can then be used to translate text. The user should also handle any errors that may occur during the translation process. I tried react0google-translate library. I want to translate my website text on single selection of languge. -
How to take file name from file in body, not from header when uploading file in Django Rest framework REST API?
I have method which should upload file ( to be specific - image in JPG format) to some external storage (it does not matter where in this issue). Im sending Post request using Postman. I want that uploaded file to take name from file which I pass in my request body. In Postman this file is passed in body as binary. Lets say this file is called dog.jpg. However my request does not work If I won't add "Content-Disposition" header, and as value of this header I need to pass ": attachment; filename=dog2.jpg". My file will be uploaded then as dog2.jpg, instead of dog.jpg. Also it is a little bit burdensome to have to change that name directly in headers everytime. Is there any way to avoid that header? Beginning of my post method: @api_view(['POST']) @parser_classes([FileUploadParser]) @csrf_exempt @login_required def upload_image(request): print(request.FILES['file']) file = request.data.get('file') For now print(request.FILES['file']) Would dog2.jpg file = request.data.get('file') Would also return dog2.jpg The rest of method I think is not important, as it is only logic to upload file to storage, which works perfectly fine. -

Error: 'Id' can only be used as a field name if the field also sets 'primary_key=True'. Removal of id doesn't change anything
I used an id field in my django models.py file. Whenever I try to make migrations, I get the following error: `SystemCheckError: System check identified some issues: ERRORS: text_modifier.Posts: (models.E004) 'id' can only be used as a field name if the field also sets 'primary_key=True'.` I'm trying to insert id = models.PositiveIntegerField() I'm trying to add the models to postgres I have tried removing the id field from the models.py file, but the error arises again (I have entirely no idea why). Also, I have tried setting the argument primary_key=True myself, this also didn't help. I understand now that id field is default in django, but the removal of it doesn't change anything. I have another problem of django not being able to see the app I'm trying to put the id field in. I have copied the name of the app from the apps.py file and used set DJANGO_SETTINGS_MODULE=search_simple.settings to ensure it works properly. Can it be the issue?

About the issue I created the project using command django-admin startproject test and updated the settings file to have mysql database details. Apart from that nothing added/updated/deleted in code. Database details in config file DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', "Name": "django", "User": "root", "Password": "", "Host": "localhost", "Port": "3306" } } Then ran the command python manage.py runserver and gave me very strange error. It says Access denied for user pankaj@localhost Question Settings file has username = root, why django pick operating system username -
