and so, I'm just interning and learning everything right now, I need to make sure that there is an input your name field and when entering the name it gives Hello,"name",I did it initially using js+node+webpack, but now I need to transfer it to Django, I have already entered and connected css files,but for some reason an error occurred with the js file I watched a lot of videos and guides, I set all the settings correctly and seemed to indicate the correct path to the folders, as well as the folders themselves are correctly arranged, but still nothing happens when you enter the name and click on the button and there is such an error in the console,if you need to throw off the code, please tell me about it, can there also be a problem that I connected css and js in the same HTML file? -
Visual Studio Django - Freezes on python manage.py createsuperuser
So, I'm new to Django and am using Visual Studio 2022 with Python 3.12 (which is apparently not fully supported by Visual Studio). When I start a fresh Django web app project, it prompts for me to create a super user. Doing so, it freezes (without any error message) as it executes "manage.py createsuperuser" (as shown in screenshot). Any suggestions? -
Issue with Swagger representation of geographical coordinates in Django using DRF and drf-yasg
I am facing an issue with Swagger representation for geographical coordinates in my Django project. I'm using Django Rest Framework (DRF) along with drf-yasg for API documentation. I have a model named Facility with a field coordinates representing geographical coordinates in the Point format. To handle this, I'm using the GeoFeatureModelSerializer from DRF-GIS and a custom serializer PointSerializer for proper representation. However, the Swagger documentation is not correctly displaying the coordinates. I suspect there might be an issue with how Swagger processes geographical data. Here are relevant code snippets: # models.py from django.contrib.gis.db import models class Facility(models.Model): coordinates = models.PointField() # serializers.py from rest_framework_gis.serializers import GeoFeatureModelSerializer from django.contrib.gis.geos import Point from drf_yasg.utils import swagger_serializer_method class PointSerializer(serializers.BaseSerializer): def to_representation(self, instance): if isinstance(instance, Point): return { 'type': 'Point', 'coordinates': [instance.x, instance.y], } def to_internal_value(self, data): if data['type'] == 'Point': coordinates = data['coordinates'] # Your coordinate validation here return Point(coordinates[0], coordinates[1]) @swagger_serializer_method(serializer_or_field=Point) def to_swagger_object(self, value): return { 'type': 'Point', 'coordinates': [value.x, value.y], } class FacilitySerializer(GeoFeatureModelSerializer): coordinates = PointSerializer() class Meta: model = Facility geo_field = 'coordinates' fields = '__all__' depth = 1 I implemented a custom PointSerializer with DRF-GIS's GeoFeatureModelSerializer in Django to handle geographical coordinates. The serializer works in regular API responses, … -

Get a dictionary of related model values
I have a model Post with some fields. Aside from that I have some models which have Post as a ForeignKey. Some examples are: class ViewType(models.Model): post = models.ForeignKey( Post, on_delete=models.CASCADE, related_name="view_types", verbose_name=_("Post"), ) view = models.CharField( max_length=20, choices=VIEW_TYPE_CHOICES, verbose_name=_("View") ) ... class HeatType(models.Model): post = models.ForeignKey( Post, on_delete=models.CASCADE, related_name="heat_types", verbose_name=_("Post"), ) heat = models.CharField( max_length=30, choices=HEAT_TYPE_CHOICES, verbose_name=_("Heat") ) ... So what I want to do here is somehow get a dictionary with all the values of those fields in my view. For example instead of doing this for all of the models that have Post as a ForeignKey: heat_type = HeatType.objects.filter(post=post) view_type = ViewType.objects.filter(post=post) dict = { "view_type": view_type.view, "heat_type": heat_type.heat, etc... } get all the relevant related fields in one go. Is there a simpler solution for that? Or do I have to manually get all queries for each model? Thanks in advance -
VS Code debugger not working (by using launch.json) for a django project
I am having trouble using the debugger in VS code. This is my first time using VS code and I'm following a Django tutorial from VS code (https://code.visualstudio.com/docs/python/tutorial-django). By the section 'explore the debugger' I got stuck, because my debugger doesn't seem to work (probably because I did something stupid or didn't do something). The thing is, I don't get an error message or something but it just keeps running. As the status bar in VS code doesn't change in the color orange, see image (which it should according to the tutorial). Statusbar while debugging My debugger also doesn't seem to stop at the breakpoint, that I have set at line 9.enter image description here. And here it just keeps running enter image description here I tried stopping the debugger and trying it again, but the outcome doesn't change. -

How do I serve my Django App in a SSH connection with limited user restrictions?
The context is the following: I'm using a SSH connection to my college's serve, on teacher's demands, in order to serve my Django application. I found out - I suppose - that by using gunicorn I can deploy my Django application. Furthermore I found out you can bind it to a specific port. When I do the following command gunicorn --bind 0.0.0.0:8000 myapp.wsgi. I proceed to my college site address, and use the port, returning 404; collegesite:8000/ What could be the problem here? Am I lacking permissions from the OS? Do I need to run gunicorn as sudo? -

How to connect bootstrap form to django form?
So, I need to have the styling of the bootstrap classes but actually have it connect to the django form in question. `` <div class="row"> <div class="col-sm-3"> <label for="last_name" class="form-label">Last Name</label> </div> <div class="col-sm-9"> <input type="text" class="form-control" placeholder="Your last name..." id="last_name" value="{{form.last_name.value}}"> </div> </div>`` {{form.last_name}} on its own for example renders the form and actually makes it connect to the database, as it should. It looks ugly though and is thus not what I need. value="{{form.last_name}}" in the above codeblock renders the start of the input tag. -

Django keeps recreating the same migration file for ManyToManyField with default value
I'm encountering a recurring issue in my Django project where Django keeps recreating the same migration file for a ManyToManyField with a default value set to MyModel.objects.all. Each time I run python manage.py makemigrations, it generates a new migration file that keeps creates the same code but increment the dependencies only, even though the model hasn't changed. When running python manage.py migrate it will show me: Running migrations: No migrations to apply. Your models in app(s): 'my_model' have changes that are not yet reflected in a migration, and so won't be applied. Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them. Here's an example of the migration code that keeps getting regenerated: # 0016_alter_my_model_my_field_name_and_more.py class Migration(migrations.Migration): dependencies = [ ("another_service", "0004_previous_migration"), ("this_service", "0015_alter_my_model_my_field_name_and_more"), ] operations = [ migrations.AlterField( model_name="my_model", name="my_field_name", field=models.ManyToManyField( default=django.db.models.manager.BaseManager.all, help_text="My field text help.", to="another_service.my_other_model", ), ), ] The model and field are defined as this: class MyModel(PolymorphicModel): ... my_field_name = models.ManyToManyField( "another_service.AnotherModel", default=AnotherModel.objects.all, help_text="My field text help.", ) ... How can I make my_field_name to have all items from my AnotherModel on database without have the makemigrations on infinite loop to recreate this? -

pyCharm warning in django code: Unresolved attribute reference 'user' for 'WSGIRequest'
in my brandnew PyCharm professional edition I get the warning "Unresolved attribute reference 'user' for 'WSGIRequest'". The warning occurs in the first line of MyClass.post() (see code below). from django.views import generic from django.db import models from django.http.request import HttpRequest from django.shortcuts import render from django.contrib.auth.models import AbstractUser class CustomUser( AbstractUser ): emailname = models.CharField() class Invoice( models.Model ): posted = models.DateField() class BaseView ( generic.DetailView ): model = Invoice def __int__( self, *args, **kwargs ): super().__init__( *args, **kwargs ) # some more code class MyClass( BaseView ): def __int__( self, *args, **kwargs ): super().__init__( *args, **kwargs ) # some more code def post( self, request: HttpRequest, *args, **kwargs ): context = { 'curr_user': request.user, } # <-- Unresolved attribute reference 'user' for class 'WSGIRequest' # some more code html_page = 'mypage.html' return render( request, html_page, context ) user ist a CustomUser object. Debugging shows, that user is a known attribute in CustomUser and the code works well. Other attributes of request like request.path or request.REQUEST are not warned. Django support is enabled.

Django ldap search restriction by group does not work, search by CN does not work

How to create blob column via Python Migrate

Annotate Django Foreign Key model instance
Is it possible in Django to annotate a Foreign Key instance? Suppose I have the following models: class BaseModel(models.Model): pass class Foo(models.Model): base_model = models.ForeignKey('BaseModel', related_name='foos') class Bar(models.Model): base_model = models.ForeignKey('BaseModel', related_name='bars') I want to count the Bars belonging to a BaseModel attached to a Foo, that is: foos = Foo.objects.all() for foo in foos: foo.base_model.bars_count = foo.base_model.bars.count() Is it possible in a single query? The following code is syntactically wrong: foos = Foo.objects.annotate( base_model.bars_count=Count('base_model__bars') ) This one would perform that job in a single query: foos = Foo.objects.annotate( base_model_bars_count=Count('base_model__bars') ) for foo in foos: foo.base_model.bars_count = foo.base_model_bars_count Is there a way with a single query without the loop? -
Double Increment Issue in TotalVote Count After Payment in django App
I'm currently developing a talent application where participants can receive votes from voters, and each vote incurs a cost. The collected funds from these votes are meant to be credited to the respective contestants. For instance, if someone casts a vote for a contestant with a count of 10 votes, the contestant's total vote count should increase by the number of votes received. However, I've encountered an issue after a user casts a vote and makes a payment. It appears that the total vote count is incrementing by twice the intended value. For example, if a user submits a vote of 10, the contestant's total vote count is increasing by 20, which is unexpected and seems incorrect. Any assistance in resolving this issue would be greatly appreciated. Please find my code below: def contestant_detail_payment(request, slug, *args, **kwargs): contestant = get_object_or_404(Contestant, slug=slug) vote_charge = contestant.get_vote_per_charge() if request.method == "POST": email = request.POST.get("email", "") vote = request.POST.get("vote", "") amount = int(request.POST["amount"].replace("₦", "")) pk = settings.PAYSTACK_PUBLIC_KEY payment = Payment.objects.create( contestant=contestant, amount=amount, email=email, vote=vote, ) payment.save() context = { "payment": payment, "field_values": request.POST, "paystack_pub_key": pk, "amount_value": payment.amount_value(), "contestant": contestant, } return render(request, "competitions/make_payment.html", context) context = { "contestant": contestant, "vote_charge": vote_charge, } return render(request, … -
