Hi. I'm a beginner programmer and I'm trying to write a Django website right now
The fact is that I have no experience at all and I use a tutorial from the Internet. This is a lesson: https://proglib-io.turbopages.org/proglib.io/s/p/django-s-nulya-chast-2-registraciya-avtorizaciya-ogranichenie-dostupa-2022-06-08 When I try to implement the user registration function and in fact just copy the actions of the teacher, my site gives the error: TemplateDoesNotExist at /register/ I don't understand why this is happening... I do not know what I am doing wrong, like I installed pipenv install django-crispy-forms, I only used the pip install django-crispy-forms command, because this command was not executed. I did everything according to the tutorial. -

Deployment: Procfile with Django Project Structure for more than one App
I need to know how you normally solve this issue. When you start a project, django creates a folder for the project and a second one inside it with the exact same name and the files like: settings.py, init.py, wsgi.py, etc. After Im done with the repo I delete one of the two folders with the same name in order to let Procfile find project.settings inside the wsgi.py. I want to be able to run the Procfile considering the original structure, because I want to learn how to create more than one app inside a project. My exact question is. How should I setup my procfile? right now is like this: web: gunicorn expenses.wsgi --log-file - But Then Procfile doesn't find expenses.wsgi This is my structure: v expenses v expenses > static __init.py asgi.py settings.py urls.py wsgi.py > finances manage.py Procfile requirements.txt runtime.txt I tried changing the Procfile from gunicorn expenses.wsgi to gunicorn expenses.expenses.wsgi but then I will tell my to change os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'expenses.settings') inside the wsgi.py I tried changing the wsgi.py from os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'expenses.settings') to os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'expenses.expenses.settings') but then it will tell me that it couldn't find the module finances. -
Djnamic checkbox, change and disabled or unhide when select
I have three columns named "passive", "discount" and "discountprice" in the rows coming from the database. I use checkbox. If the passive is full, when one of the data-x with the passive label is selected, the others will be disabled. If the discount is full, when one of the ones with the data-y discount tag is selected, the discount price of those with the same discount tag will replace the normal price. It cannot be both discounted and passive. There may be different discount groups or liability groups. I'm stuck. What I wrote was of no use. html {% for mal in mlazm %} <input class="form-check-input" type="checkbox" value="{{ mal.0 }}" name='mlzm{{ forloop.counter }}' data-price="{{ mal.3 }}" data-bprice="{{ mal.7|default:'0' }}" id="{{ mal.0 }}{{ mal.0 }}" {% if mal.4 %}disabled{% endif %}> {%endfor%} js var $checkboxes = $('.myCheckBox').change(function() { var $checked = $checkboxes.filter(':checked'); if ($checked.length >= 3) { $checkboxes.filter(':not(:checked)').prop('disabled', true); } else { $checkboxes.prop('disabled', false); } }); -
My context processor document is being a complete arse
I am literally going to scream. Why can I not get any bloody text to appear from my function in my contect-processor.py to work? I am going to scream so bloody loudly because I am fed up of Django not doing as it's told. PROJECT -|project -|careers -|models.py -|context_processor.py -|templates -|template.html #context_processors.py from .models import Careers def careers_exist(request): # Check if there are any active careers careers_available = Careers.objects.filter(active=True).exists() # Prepare the context dictionary based on availability if careers_available: header = {'header': 'Current vacancies'} else: header = {'header': 'No Vacancies'} return {'header' : header} #template.html <h2>{{ header.header }}</h2> Why is my template still blank despite doing everything correctly. What a stupid bloody thing. -
Which languange/framework should I use? [closed]
I'm getting ready to do my final project. It should be a web app that will show fitness progress by entering it into the system. The progress just given, which has to be written down by the user, will be shown in the form of a graph. I am mainly concerned about the look of the overall application, but at the same time a good backend of course with a database. The original idea was to use Python with Django and React for frontend. But recently I was recommended to use Next.js for both frontend and backend. What is your opinion on what you would use? Or do you have any other opinion? -

Choose which model manager to use when doing prefetch_related?
I have a Product model in my Django app, which uses a custom model manager where all the prefetch_related statements are made: class ProductManager(models.Manager): def get_queryset(self): return ( super() .get_queryset() .select_related("core_product") .prefetch_related("images") .prefetch_related("bundled_products") ) class Product(models.Model): _base_manager = ProductManager objects = ProductManager() # ... model fields This works fine; when I use the ORM and within the Admin the custom manager is used, preventing a whole bunch of duplicate queries. The problem is when I have another model that has a prefetch_related to the Product model: it now inherits all the prefetch_related from the Product, even though that's not necessary. It causes a whole bunch of unnecessary queries to be made. class OfferManager(models.Manager): def get_queryset(self): return ( super() .get_queryset() .select_related("flag") .prefetch_related("condition_products") .prefetch_related("limited_to_users") .order_by("-priority") ) Here the condition_products field is that Product model from above, and just by including this prefetch_related, all of its prefetch_related statements are also inherited. How can I prevent this from happening? Can I specify which object manager to use in the prefetch_related - so that is uses a "bare" manager? -
Django: how to filter based on custom field
I have a custom field in my extra action view that gets added by overriding to_representation() in serializer. I want to add a filter based on that value. How can I achieve that? views.py class MyFiltersetclass(filters.Filterset): name = filters.CharFilter(lookup_expr="exact", field_name="name") class Meta: model= MyModel fields = ["name"] class MyViewset(): .... @action(detail=True, method=["get"], queryset=MyModel.objects.filter(type=1), serilizer=MyModelSerializer, filterset_class=MyFiltersetclass) def action(self, request, *args, **kwargs): qs = self.get_object() queryset = obj.filter_queryset(queryset) page = obj.paginate_queryset(queryset) if page: serializer = obj.get_serializer(page, many=True) else: serializer = obj.get_serializer(queryset, many=True) return obj.get_paginated_response(serializer.data) model.py class MyModel(models.Model): name = models.TextField(blank=True, null=True) summaries = models.JSONField(blank=True, null=True) @property def summary(self): if not self.summaries: return {} return custom_func(self.summaries) class Meta: db_table = "model_view_1" managed = False serializer.py class MyModelSerializer(serializers.ModelSerializer): summary = serializers.ReadOnlyField() def to_representation(self, instance): data = super().to_representation(instance) summary = data.pop("summary") data["field_1"] = summary.get("field_1") return {**data} class Meta: model = MyModel exclude = ["summaries"] Now I want to add a filter that could filter based on field_1 just like how we have added filter for name in filterset class. -

Extract the item image out of an RSS feed (multiple RSS feed types - feed parser/python)
Working on a project that pulls articles from 20+ rss feeds and the the variety of feed formats for where the articles image is, is driving me bonkers. I'm happy for the articles image to be missing in some cases, and I'll fall back to a set image but I don't want that happening more than 20% of the time. Using Python & Feedparser (DJANGO Project) I've gotten this far: # Try and get the image url try: # Looking for images embedded in enclosures post_image = sanitize_url(str(c.enclosures[0].href)) except: try: # Looking for images embedded in media content post_image = sanitize_url(str(c.media_content[0]["url"])) except: try: # Looking for images embedded in content post_image = sanitize_url(c.content[0]["value"]) except: post_image = "no image found" Had to build a sanitise URL function that does 3 things: Takes a string that extracts out a URL (in situations where the above pulls more than the URL) Trims URLS down to remove parameters that might cause problems i.e 342.jpg?w=25 Then does a final check of the string to make sure it has a mimetype in case the final url is not an image. I'm going in circles here, for every example of an RSS feed this does work on, … -

I'm using Django and django-auth-ldap. How do I make all users to be staff?
I'm using django-auth-ldap for athentication. I want all new users to be assigned as staff. How do I do that? I know about AUTH_LDAP_USER_FLAGS_BY_GROUP, but I don't want to bother assigning people to a specific group. I know that there exists django_auth_ldap.backend, but I can't find a good working example of it. As a follow up (or combination?), I want to assign a set of default user permissions, for new users. Thanks. -

Is there a way to annotate the count for all objects without grouping by another column?
I have code that looks like the following: filtered_queryset = Object.objects.filter(...misc filters) match time: case "year": qs = filtered_queryset.annotate(year=TruncYear("created_at")).values("year") case "month": qs = filtered_queryset.annotate(month=TruncMonth("created_at")).values("month") case "week": qs = filtered_queryset.annotate(week=TruncWeek("created_at")).values("week") case _: qs = filtered_queryset final_count = qs.annotate(count=Count("id")) In each case, I am expecting data that looks like the following # Each case { [{ "TIME": ... "count": ... }, ... ] } # Default { [{ "count": ... }] } I was under the impression that Count() was a terminal expression in django and that the queryset would be evaluated. However, the default case returns a queryset instead of evaluating. What am I missing here that causes it to not evaluate the queryset? I know that I can just call filtered_queryset.count() instead of trying to do this via annotate, but it causes extra code to check for the default case and adds code smell. -
Using Kerberos to authenticate Django Application in Corporate Environment
I am trying to use Kerberos and LDAP3 to authenticate my Django Application inside the corporate network.
