Multiple Django Projects on Apache Server with mod_wsgi is trying to load wrong project libraries?
I'm trying to run multiple Django projects on one server. The server is Windows and I am using mod_wsgi with Apache. Normally, each project lives on it's own server and everything works great - but for dev/staging purposes I am trying to just serve them all from the same server (I've done this successfully with other groups of projects on another server, but they were Flask applications) My structure looks similar to this: ProjectA (this project contains the authentication / login / logout) - appa1 (shared templates / static files) - appa2 ProjectB - appa1 (shared templates / static files) - appb1 - appb2 ProjectC - appa1 (shared templates / static files) - appc1 - appc2 My VirtualHost setup is pretty straightforward: <VirtualHost dev.projecta.mydomain.com:80> ServerName dev.projecta.mydomain.com Redirect / https://dev.projecta.mydomain.com </VirtualHost> <VirtualHost dev.projecta.mydomain.com:443> ServerName dev.projecta.mydomain.com WSGIScriptAlias / "C:/projecta/projecta.wsgi" CustomLog "logs/projecta_access.log" common ErrorLog "logs/projecta_error.log" SSLEngine on SSLCertificateFile "C:/path/to/projecta_cert/cert.cer" SSLCertificateKeyFile "C:/path/to/projecta_cert/project.key" <Directory C:\projecta> Require all granted </Directory> </VirtualHost> <VirtualHost dev.projectb.mydomain.com:80> ServerName dev.projectb.mydomain.com Redirect / https://dev.projectb.mydomain.com </VirtualHost> <VirtualHost dev.projectb.mydomain.com:443> ServerName dev.projectb.mydomain.com WSGIScriptAlias / "C:/projectb/projectb.wsgi" CustomLog "logs/projectb_access.log" common ErrorLog "logs/projectb_error.log" SSLEngine on SSLCertificateFile "C:/path/to/projectb_cert/cert.cer" SSLCertificateKeyFile "C:/path/to/projectb_cert/project.key" <Directory C:\projectb> Require all granted </Directory> </VirtualHost> <VirtualHost dev.projectc.mydomain.com:80> ServerName dev.projectc.mydomain.com Redirect / https://dev.projectc.mydomain.com </VirtualHost> <VirtualHost dev.projectc.mydomain.com:443> ServerName dev.projectc.mydomain.com … -

Running a celery task outside the django framework
I have a django/celery application that is working fine. In normal operations tasks get created and inserted into the worker queues as expected. I am trying to create a separate python script that will be run manually, that is attempting to insert a task into the worker queue... and it is not working. The test function is simple: @shared_task() def testtask(num=100, tag=0): for i in range(num): print_log("in testtask {0} {1}".format(i, tag)) time.sleep(1) return From the python3 prompt, I do the following: >>> os.environ.setdefault("DJANGO_SETTINGS_MODULE", "raxakprotect.settings.dev") >>> import django >>> django.setup() >>> from test import testtask # test has other django dependencies hence the django.setup() >>> testtask(10) # This works fine... but >>> testtask.delay(10) # hangs indefinitely Don't know why this is the case. Do I have to connect separately to the celery broker somehow? Watching celery events screen shows no events or entries being created. Thanks --prasanna -

How to concat the django template variable in the jQuery html string for appending dynamically to the body
From the table, I can fetch the ID of the user, to get the first_name of the user, I have to get it from another table, to do this task I follow related_name method. for example, {{ data.custom_user.user_profile.first_name}} where user_profile is the related_name in the model.

Installing a version of Django REST framework that is compatible with Django 4+
I am in the process of upgrading from Django 3.2 to Django 4.0. When I do so, I get the following error: ImportError: cannot import name 'ugettext_lazy' from 'django.utils.translation' And the error seems to stem from this import: from django.utils.translation import ugettext_lazy as _ in rest_auth/registration/serializers.py I'm currently running Django 4.0.10 with djangorestframework 3.13.0, and I'm a bit confused because according to Django REST framework's release notes v3.13.0 should support Django 4.0 (I also tried v3.14.0, same results). What am I missing here? -
combined use of RedirectView and i18n_patterns in Django 4.0.3
I am having problems using RedirectView inside i18n_patterns in my urls.py file. My current situation is this: urlpatterns = i18n_patterns( path('', RedirectView.as_view(url='/home/', permanent=True)), path('adm/', admin.site.urls), path('rosetta/', include('rosetta.urls')), path('home/', include(('home.urls', 'home'), namespace='home')), ) What happens is that if I connect to my site (for this example mysite.com) I am not redirected to mysite.come/home, nor even to mysite.com/en/home. If I remove i18n_patterns urlpatterns = [ path('', RedirectView.as_view(url='/home/', permanent=True)), path('adm/', admin.site.urls), path('rosetta/', include('rosetta.urls')), path('home/', include(('home.urls', 'home'), namespace='home')), ] and I connect to mysite.com I am correctly redirected to mysite.com/home and the site works correctly. I have recently implemented i18n for the first time so I am not familiar with the topic. I tried splitting urlpatterns into two but got no results: urlpatterns = [ path('', RedirectView.as_view(url='/home/', permanent=True)), ] urlpatterns += i18n_patterns( path('adm/', admin.site.urls), path('rosetta/', include('rosetta.urls')), path('home/', include(('home.urls', 'home'), namespace='home')), ) -
Passing Value to create initial value in form
I am trying to create a center of a project (foreign key). However, when I call the url to create a center the project which this center should belong to is not automaticly set. So the user has to choose the project. The goal is to prefill the form element 'Project' with the name of the Project the id of which is specified in the url, the last element of the url is the id of the project as seen here: http://192.168.10.84:8080/procure/centercreate/5 Therefore I have to look up the name of the project with id 5, fill the form element and make it none editable. what I have so far. model of center: class Center(models.Model): CenterName = models.CharField(max_length=60, null=False) Project = models.ForeignKey(Project,on_delete=models.CASCADE) def __str__(self): return self.CenterName in the url.py path('centercreate/<int:pk>', views.CenterCreate.as_view(), name='center_create'), in the views.py: class CenterCreate(CreateView): model = Center form_class = CenterCreateForm template_name = 'Procure/center_create.html' def get_success_url(self): return reverse('centers_sys', kwargs={'pk':self.object.Project_id}) connected form I use: class CenterCreateForm(forms.ModelForm): class Meta: model = Center fields = "__all__" template used: {% extends "base_generic.html" %} {% block content %} <div id="container" > {% if user.is_authenticated %} <p>Welcome to ProcEdu - developed by <em>BZG</em>!</p> <h3>You are adding a Center to Project: <!-- PROJECT -->> </h3> … -

Will a Django Webapplication work on a Hostpoint standard Webserver?
I can't seem to find any confirmation anywhere that the standard webhosting service for HostPoint will be able to host my Django project. They seem to suggest I need a Managed Server to run my project, is that the case? I'm kind of new to all of this so I'm sorry if this is a stupid question. I've rummaged through hostpoint's site and can't find anything that helps me further, I've even written an email to hostpoint themselves but still haven't gotten an answer. -
Matplotlib and mpld3: how to show the corresponding y value of line plot in a tooltip based on hover x value?
I'm creating a graph in which I would like to show the Y value of the plot in a tooltip based on the hover x value. For this I am using Python with libraries: Matplotlib and mpld3. In my current version I have the tooltip showing up when I hover the line in the graph but I want it to show up when I just hover over the graph. For your visual presentation: This is what I have now (mouse hovering in red circle): My mouse is hovering in the red circle But I would like it to already show up when I hover above or below it like you can see in next picture. If I hover here I want the tooltip also to show with current hover x value and corresponding y value of the blue line I used the plugins.PointHTMLTooltip and it's working but only when I hover over the blue line, not when I just hover over the graph. -

Exclude user from an annotation query
I'm trying to query the users presents in a certain conversation. I finally got it working with this annotation: products = products.annotate( conversation_users=Subquery( Conversation.objects.filter( product=OuterRef('pk') ).annotate( users_array=ArrayAgg('users__username') ).values_list('users_array', flat=True)[:1] ) ) This is returning a list with the user present in the conversation (in most cases only two). I need to exclude from there the request.user so I get always the value of the user who I am having the conversation with. I tried using this Q query trying to exclude the request.user: .filter(~Q(users=user)).values_list('users_array', flat=True)[:1] ) but it is making the field now return None. How can I accomplish that? Edit 1: Those are the relevant models, Product model: class Product(models.Model): creator = models.ForeignKey( User, on_delete=models.CASCADE, related_name='anken') content = models.TextField(blank=True, null=True) date = models.DateTimeField(auto_now_add=True) active = models.BooleanField(default=True) intouch = models.ManyToManyField( User, related_name='product_intouch', blank=True) And this is the Conversation model: class Conversation(models.Model): product = models.ForeignKey( Product, on_delete=models.CASCADE, related_name='conversations') users = models.ManyToManyField(User, related_name='conversations') def validate_unique(self, *args, **kwargs): super().validate_unique(*args, **kwargs) if Conversation.objects.filter(product=self.product, users__in=self.users.all()).exists(): raise ValidationError( 'A conversation with the same Product and user already exists.') -
Using sass preprocessor with a django+svelte project
I am creating a project using django and svelte framework mainly, I was wondering if it is possible to use sass preprocessor within my svelte components(not in the css files that are located in the static folder). I want to use it directly in the svelte component not in any other files. What is usually do is write code in svelte, build the code using "npm run build" then run the django server. Whenever I try to add sass by changing the rollupconfig, the command "npm run build" breaks and start giving error.

Created celery.py in project default app robot (same folder as settings.py) : import os from celery import Celery os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'robot.settings') app = Celery('robot') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() In the settings.py line added : CELERY_BROKER_URL = 'redis://localhost:6379/0' In the project's default app robot __init__ added lines: from .celery import app as celery_app __all__ = ['celery_app'] In custom django app user created tasks.py and following func for test: from celery import shared_task @shared_task() def simple_task(): print("SOME RESULT") When I run command in PowerShell celery -A robot worker I only get a message: [2023-05-10 12:42:23,232: WARNING/MainProcess] C:\Users\kosan\Documents\Python\venvs\robot_dreams_study\django\Lib\site- packages\celery\fixups\django.py:203: UserWarning: Using settings.DEBUG leads to a memory leak, never use this setting in production environments! Then I try to run a task (simple task with just printing a word) with Django Shell. As result I get an output in Django Shell: >>> simple_task.delay() <AsyncResult: a58d1627-7469-4a7a-b761-bca74dcb00c2> And that's all. No any output in celery consol or somewhere else. I have tried to run celery with celery -A robot … -
Celery beat cannot update currency exchange rates with django-money
I use django-money, then I ran celery beat to update currency exchange rates every 60 minutes with the code below. *I followed django-money doc: # "core/celery.py" import os from celery import Celery os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'core.settings') app = Celery('core') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() @app.task(bind=True) def debug_task(self): print(f'Request: {self.request!r}') # "core/tasks.py" from celery import shared_task from djmoney import settings from django.utils.module_loading import import_string @shared_task def update_rates(backend=settings.EXCHANGE_BACKEND, **kwargs): backend = import_string(backend)() backend.update_rates(**kwargs) print("Successfully updated") # "core/settings.py" from celery.schedules import crontab OPEN_EXCHANGE_RATES_APP_ID = '5507ba2d9b8f4c46adca3169aef9c281' # Here CELERY_BEAT_SCHEDULE = { 'update_rates': { 'task': 'core.tasks.update_rates', 'schedule': crontab(minute='*/60'), 'kwargs': {} # For custom arguments } } But, I got the error below even though I set OPEN_EXCHANGE_RATES_APP_ID in settings.py as shown above: django.core.exceptions.ImproperlyConfigured: settings.OPEN_EXCHANGE_RATES_APP_ID should be set to use OpenExchangeRatesBackend So, how can I solve the error to update currency exchange rates every 60 minutes with celery beat?
