How to render to specific html div with value from django views?
I am trying to deploy a machine learning model using Django. Here I am trying to do is take input from the HTML form, predicting value using a trained model, and sending that result value to the HTML page. Still here working good. But I want to go to a specific division(div tag) of the HTML page based on division(div tag) id. Please help me, anyone; how can I fix this problem. HTML code File name :- nlpdocs.html <div style='background:pink;height:300px;width:600px;left:150px;position:relative' id="spam_try"> <form action='smsclassifier' method='POST' enctype='multipart/form-data' > {% csrf_token %} <h2 style='left:80px;position:relative'>SMS Spam Classifier</h2> <label>SMS :- </label> <textarea id="smstext" name='smstext' rows="4" cols="50" placeholder="Enter SMS here </textarea> <button type='submit' > Submit</button> </form> </div> <p><h4 style="color: #55CEFF">Input SMS Text :- </h4><h6> {{sms_text}}</h6></p> <p><h4 style="color: #55CEFF">Entered SMS is :- </h4><h6>{{result}}</h6></p> I create urls file within the django app folder. urls.py urlpatterns = [ path('',views.home_view,name='home_view'), path('index.html',views.home_view,name='home_view'), path('nlpdocs.html',views.nlpdocs, name='nlpdocs'), path('smsclassifier', views.sms_spam_classification, name='smsclassifier'), ] views.py @csrf_exempt def sms_spam_classification(request): """ Input :- Text Output :- string Return :- classify input text spam or not """ if request.method == 'POST': sms_text = request.POST.get('smstext') result = predict_new_text(sms_text) result_dict = {'result':result, 'sms_text':sms_text} return render(request, 'nlpdocs.html#spam_try', result_dict) If I send the only nlpdocs.html to render function, that one works but goes to … -
Django - Handle a user vote per set amount of time
I'm working on a Django site that allows users to post to car shows and then vote for entries. Previously you could just vote for your top 3, but now I'm trying to add the ability to re-vote after some configurable amount of time (eg. daily, weekly). The first option lent itself to Django m2m fields nicely. Essentially just added a 'votes' m2m field to each entry and then tracked who voted. With timing involved though I separated it out into a new 'vote' model as shown below. The problem I'm having though is it introduces some pretty complicated queries where anytime I want to get whether a user can vote, I have to check against the timestamps. I was wondering if anyone had a better way to handle this or a clever way of integrating into the model an 'active' indicator in terms of whether the vote has expired based on the timing of the event. class Vote(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, null=True, related_name="votes", on_delete=models.CASCADE, ) post = models.ForeignKey( Post, related_name='votes', on_delete=models.CASCADE, ) timestamp = models.DateTimeField(auto_now_add=True) An example query: # Returns an active vote of a user/entrant combo that has not been reset by a voting period. def get_active_vote(self, … -
Django: 'int' object is not iterable when different serializers in a Viewset
I have an issue when making a GET request on this endpoint: /api/stock/{bar_id}/. It should return stock information for a specific Bar ID. In my schema, the Stock model contains the following properties: bar_id as a foreign key. ref_id as a foreign key. stock as integer. sold as integer. In order to get the relevant information, I intended on calling the BarDetailsSerializer through the Stock Viewset, thinking it might be easier than having to filter the Stock table according to the bar_id value provided in the URL, as it would automatically provide the Stock collection related to that specific Bar ID. Making a GET request on http://localhost:8000/api/bars/1 (as shown below) provides the information I need. However when I'm trying to get this response via the Stock Viewset with this end-point http://localhost:8000/api/stocks/1 I get the following error: TypeError at /api/stocks/1/ 'int' object is not iterable So is what I'm trying to do even possible in the first place, or is there a better way or some best practise to apply here? Thanks for your responses! Here is my Stock Serializer file: from rest_framework import serializers from ..models.model_stock import Stock from .serializers_reference import * from .serializers_bar import * class StockIndexSerializer(serializers.ModelSerializer): """ Serializer … -

Return value for importlib.import_module()
I have a strage problem with importlib.import_module(). I cannot find documentation which return value is expected. It seems that return values sometimes different. I'm using python3.8 with Django 2.2 and there is a function import_string() https://github.com/django/django/blob/stable/2.2.x/django/utils/module_loading.py#L17 def import_string(dotted_path): """ Import a dotted module path and return the attribute/class designated by the last name in the path. Raise ImportError if the import failed. """ try: module_path, class_name = dotted_path.rsplit('.', 1) except ValueError as err: raise ImportError("%s doesn't look like a module path" % dotted_path) from err module = import_module(module_path) try: return getattr(module, class_name) except AttributeError as err: raise ImportError('Module "%s" does not define a "%s" attribute/class' % ( module_path, class_name) ) from err The line module = import_module(module_path) imports a module, and sometimes this module has attributes, but sometimes it doesn't. So for example if I do print(dir(module)) sometime I see object like this: ['BaseCache', 'CONNECTION_INTERRUPTED', 'ConnectionInterrupted', 'DJANGO_REDIS_SCAN_ITERSIZE', 'RedisCache', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', 'functools', 'import_string', 'logging', 'omit_exception', 'settings'] But sometimes it looks like this: ['__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__'] So obviously for second case next line after import fails: return getattr(module, class_name) I wonder why this may happen? I think it's not backend library problem … -

Improperly configured error when running django-admin check
I'm relatively new to Django and programming, so I have no idea what caused this error or how to fix it. I asked another question related to the same error but got no responses so here's a simpler version. When I run Django-admin check (along with various other commands not including run server) I get the following error. django.core.exceptions.ImproperlyConfigured: Requested setting LANGUAGE_CODE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. I have spent hours googling and nothing I find works (I either get this error or a module not found error).

Using CookieCutter-Django & Docker, how do I get a 'hello, world' app to run on the development server?

Django getting one to many on same query
I need to display a view with Courses with its dependable Lectures on an accordion in html. A Course has many Lectures. class Course(models.Model): title = models.CharField(max_length=1500) def __str__(self): return self.title class Lecture(models.Model): title = models.CharField(max_length=1500) course = models.ForeignKey(Course, on_delete=models.CASCADE) content = models.TextField() def __str__(self): return self.title It seems like all the examples I have found. Get the relationship after doing a filter or getting the first object like this: Course.objects.first().lecture_set.all() This gets all the lectures for the first one. But I need to get all Courses with all lectures. Something like this: Course.objects.all().lecture_set.all() or Course.objects.filter('all').lecture_set.all() This way I could iterate over Courses and then on each Course iterate again with Course.lectures Does anyone know the best practice to achieve this? -

How to send large post request in flutter
I'm trying to upload my users' contacts to my server (running django-rest-framework) from flutter, but am having a hard time due to the size of the request. The contacts are sent from a screen within a bottom navigation bar, so I would like to request to continue even when the user switches pages (we're using bloc and flutter clean architecture to organize logic). I looked into https://pub.dev/packages/flutter_uploader and multipart uploads but it seems that most are geared towards files rather than json in the post body. The size of the contacts request is partly due to the included avatar images, encoded in base64. I have them as base64 encoded strings because that is easier to parse and deserialize on the server, and I'm not sure how to parse files in django-rest-framework ModelSerializers. Is there any way to upload a large json (List<Map<String, dynamic>>) request to my server so that: The request continues even when the bloc that called the usecase->repository->remotedatasource.dart is recycled when user selects different window in bottom navigation bar. The request contains the images in a way I can process without too much django-rest-framework code and allows me to automatically save the images to s3 as happens automatically … -

Filter ForeignKey choices in an Admin Form based on selections in same models ManytoMany Field?
I am making a "matches" model that currently has these fields in them: event = models.ForeignKey(Event, on_delete=models.RESTRICT) match_participants = models.ManyToManyField(Wrestler, on_delete=models.RESTRICT, null=True, blank=True,) match_type = models.CharField(max_length=25, choices=match_choices, default=BLOCK) match_result = models.CharField(max_length=25, choices=result_choices, default=NOT_OC) winner = models.ForeignKey(Wrestler, on_delete=models.RESTRICT, null=True, blank=True, related_name="winner") In my scenario the "winner" can only be one of the foreignkeys chosen in "match_participants", I would really like to filter the winner field to only those chosen foreignkeys. Is this possible? I know you can filter foreign key selections based on entries into other models, but not too sure about same table entry. Here's a UML example of what my database structure currently is: -
Django - Why is my form invalid when a non-required field is not filled?
My form triggers form_invalid when the field "category" is empty. The weird thing is, when the view displays, the "description" field does not have the asterisk indicating it's required, unlike "name" or "enabled", for instance. Also, when I try to send the form with an empty name, it correctly displays a little yellow mark and says "This field is required", but it doesn't say that when the category is empty. So, it seems to correctly recognize that the category is not required, it just says it's invalid after I send the form. My form looks like this: class ProductForm(forms.Form): name = forms.CharField(max_length=80, required=True) category = forms.ModelChoiceField(queryset=None, required=False, label='Categoría') description = forms.CharField(max_length=150, required=False) price = forms.FloatField(required=True) image = forms.ImageField(allow_empty_file=True, required=False) extras = forms.FileField(allow_empty_file=True, required=False) enabled = forms.BooleanField(required=False, initial=True) def __init__(self, user, *args, **kwargs): self.user = user super(ProductForm, self).__init__(*args, **kwargs) self.fields['name'].label = 'Nombre' self.fields['description'].label = 'Descripción' self.fields['price'].label = 'Precio' self.fields['image'].label = 'Imagen' self.fields['extras'].label = 'Extras' categories = Category.objects.filter(store=Profile.objects.get(user=user).store) if categories.count() == 0: self.fields['category'].required = False self.fields['category'].queryset = categories self.fields['enabled'].label = 'Habilitado' It is included to my view in this way: class ProductCreateView(LoginRequiredMixin, CreateView): template_name = 'products/product_form.html' model = Product fields = ["name", "category", "description", "price", "image", "enabled", "extra"] success_url = reverse_lazy("orders:products") And … -

django Pycharm 2020.2.2 not resolving static files when using "pathlib.Path" to address BASE_DIR
I'm using the latest version of Pycharm, 2020.2.2 and django 3.1. In my project, I removed the default settings.py and created a directory named settings, so the whole project root looks like: tsetmc ├── asgi.py ├── celery.py ├── context_processors.py ├── __init__.py ├── settings │ ├── base.py │ ├── __init__.py │ ├── local.py ├── urls.py ├── views.py └── wsgi.py and in the base.py, I defined the static files setting as: from pathlib import Path BASE_DIR = Path(__file__).resolve().parent.parent.parent ...

I enabled Django Support, set Django project root and settings in the Pycharm settings accordingly and also set the Template Language as Django; but it didn't solve the issue.

How to show files after clicking on certain category on html/django?
