ALLOWED_HOSTS when using Django behind Caddy reverse proxy
Using Django behind a Caddy reverse proxy leads to a lot of error notifications like the following: Invalid HTTP_HOST header: 'www.msftncsi.com'. You may need to add 'www.msftncsi.com' to ALLOWED_HOSTS. Isn't Caddy supposed to only pass on requests from my own domain to the Django app? The respective Caddyfile is: mydummyyapp.com { # Use 'route' to allow this ordering. Otherwise, 'file_server' would need to come last. route { # Redirects just to be nice. redir /login /accounts/login permanent # Serve static files directly. file_server /static/* { root /home/apps/mydummyapp } # Pass on everything else to django/daphne. reverse_proxy 127.0.0.1:8000 } log { output file /var/log/mydummyapp_access.log { roll_size 1gb roll_keep 5 roll_keep_for 168h } } } I would assume that requests that do not originate at mydummyyapp.com to not even reach the Django/daphne server running at 127.0.0.1:8000. Naive and wrong? -

How can I skip authentication in a Django APIRequestFactory call?
So essentially I want to make a request to a ViewSet without requiring to authenticate, does Django APIRequestFactory make this possible? This works: from django.test import TestCase from .views.SomeViewSet from rest_framework.test import APIRequestFactory class ViewSetsTest(TestCase): ... ... ... def test_db_instance_viewset(self): api_request = APIRequestFactory.patch("", HTTP_AUTHORIZATION="Bearer xyz123ppouu") detail_view = SomeViewSet.as_view({'patch': 'update'}) response = detail_view(api_request) self.assertEqual(response.status_code, 200) But the issue is, the bearer token is something that is generated 'somewhere far' every 24 hours. Hence, I want to skip authentication. Thank you in advance. -

Is it good way to write all js code in html page and include that html page in another html page insted of .js file?
I just want to know that is it a good idea to write all javascript code in an HTML(instead of writing in .js) file and that the HTML file will be included in another HTML file. I'm writing js code in an HTML file because I can access Django templates in an HTML file. Django templates are not accessible in pure JS files. -

Show specific form-fields at specific places in the HTML template (Django)
I have a form with three fields field1,field2,field3 - in my template I want to show those fields at specific places, and not together. At best field1, field2 are "shown together" and then a bit further down, I need field3 to be shown. My HTML is right now <div class="content-section"> <div class="add-link-wrapper"> <legend class="border-bottom mb-4"> Add product </legend> <form method="POST"> {% csrf_token %} {{form|crispy}} <div class="form-group"> <button class="btn btn-outline-info" type="submit">Add</button> </div> </form> </div> </div> but {{form}} shows all three fields - I would like to have it a bit like <div class="content-section"> <div class="add-link-wrapper"> <legend class="border-bottom mb-4"> Tilføj produkt til tracking </legend> <form method="POST"> {% csrf_token %} {{form.field1 and form.field2 |crispy}} <!-- Show field1 and field 2 here --> <div class="form-group"> </div> </form> some more html code </div> {{form.field3|crispy}} <!-- Show field3 here --> <button class="btn btn-outline-info" type="submit">Add</button> </div> -
Show all possible error-messages for fields (Django)
In Django, say I have a User field and I want to change the "this user alread exist" error message. I know I can parse a dictionary in e.g forms.py like class MyForm(Form): . . . error_messages={"unique": ("Wups, enter a unique username")} but it requires I know the key/value pair, which might not always be obvious what the key is. Is there a way (in the Django documentation it seems pretty scattered) where these error-message key/value pairs are, or what is the most easy way to find those? -

Why do I get "reverse accessor for 'model.user' clashes with reverse accessor for 'model.account' even though I set AUTH_USER_MODEL?
I've seen the same question posted a few times, and the answer is always.. did you set AUTH_USER_MODEL? Here is the snippet from my settings.py file. ## Accounts AUTH_USER_MODEL = 'accounts.Account' Here is the error message I am getting when I try to generate migrations for my new model. ERRORS: admin.LogEntry.user: (fields.E304) Reverse accessor for 'LogEntry.user' clashes with reverse accessor for 'LogEntry.account'.

I run the command again and get the same result. I know that I could define a related_name on the field, but I would rather address the underlying problem. It shouldn't class with LogEntry.user because I am not creating any association between those models directly... or am I? -
Date range filter doesn't work as expected
I made a custom filter by date range with a django-filter library. class AccountingStockBalanceFilter(filters.FilterSet): date = filters.DateFromToRangeFilter(method="filter_date") @staticmethod def filter_date(queryset, name, date_slice): queryset = queryset.filter( invoice_product__invoice__supplier_creation_date__range=( date_slice.start, date_slice.stop, ) ) return queryset but if I do request like this http://localhost/api/accounting/stock_balances/?date_after=2021-03-01&date_before=2021-04-20 then it won't return anything...Though if I do request like http://localhost/api/accounting/stock_balances/?date_after=2021-02-01&date_before=2021-04-20 (I have changed date_after from 2021-03-01 to 2021-02-01), then I'll get in some entries in response with only the date of 2021-02-11. Then I made this filtering with a built-in filter() function like this: class AccountingStockBalanceFilter(filters.FilterSet): date = filters.DateFromToRangeFilter(method="filter_date") @staticmethod def filter_date(queryset, name, date_slice): queryset = filter( lambda wp: date_slice.start < wp.invoice_product.invoice.supplier_creation_date < date_slice.stop if wp.invoice_product.invoice.supplier_creation_date else wp, queryset, ) ids = [wp.id for wp in queryset] queryset = ( WarehouseProduct.objects.prefetch_related( "invoice_product__invoice__order__serviceinvoice_set", "invoice_product__invoice__service_set", "invoice_product__invoice__order__invoice_set__invoiceproduct_set", "invoice_product__invoice__invoiceproduct_set", "invoice_product__invoice__order__serviceinvoice_set__service_set", "invoice_product__invoice__self_serial_number", "invoice_product__invoice__self_proforma_serial_number", ) .select_related( "nomenclature__category__unit_of_measure", "invoice_product__invoice__order", "invoice_product__invoice__supplier", "locator", ) .filter( ~Q(nomenclature__type=Nomenclature.Type.ASSEMBLY), locator__warehouse_id=1, quantity__gt=0, id__in=ids, ) ) return queryset And it works correctly returning me a response with dates like 2021-03-06 e.g. but it costs extra database queries and I got 18 queries instead of 9.

Django Rest Framework: Is it possible to allow users to get/post data via ajax but not directly via viewset url?
I'm learning web development since a few months, so the answer could be quite trivial: I also couldn't find anyone asking that before so it's probably a really stupid question, neither in the [drf official doc](https://www.django-rest-framework.org/api-guide/viewsets/). Most similar question I could find is [this](https://stackoverflow.com/questions/57328203/django-user-with-limited-permissions-can-see-all-default-models-in-rest-framewor), and I understood it but did not really help me. My problem is that I have a drf viewset very simple, like this, in views.py: from .serializers import MyModelSerializer from .model import MyModel from django.contrib.auth.decorators import login_required @method_decorator(login_required, name='dispatch') class MyViewSet(viewsets.ModelViewSet): serializer_class = MyModelSerializer queryset = MyModel.objects.all() My urls.py looks like this: from views import MyViewSet from rest_framework.routers import DefaultRouter router = DefaultRouter() router.register('myviewset', MyViewSet, basename='myviewset') urlpatterns = [ path('viewset/', include(router.urls)), # ... other paths ... ] Inside my javascript (jQuery) code I call this url, in some ajax requests: it performs well and that's wonderful. Unfortunately, users can do the same thing directly by going to /viewset/myviewset/ and this is a real problem to me. So, is it possible or am I simply using the wrong module to do this? In that case, what other module/objects could I use? Thank you very much. -

pipenv virtual environment name disappears everytime the VS Code terminal is refreshed
I was working on a Django project after activating the virtual environment created through pipenv. The virtual environment name given in brackets (lead-manager-full-stack-8btqndKQ) in the vs code terminal disappears everytime i runpython manage.py runserver When i select the powershell as terminal and runs pipenv shell again in order to activate the environment again it shows : Shell for C:\Users\USER.virtualenvs\lead-manager-full-stack-8btqndKQ already activated. No action taken to avoid nested environments. But it still doesn't show the virtual environment name inside the brackets like it is supposed to show. Then i tried to run pipenv shell in cmd and this time it shows the virtual environment name in bracket in the terminal. But whenever i reload the terminal or choose new terminal, it doesn't show the virtual environment. There must be a way to activate the virtual environment at all time, even after reloading the terminal if i am in a folder containing virtual environment right? Because activating virtual environment everytime i reloads the terminal doesn't seem like a good approach. -

I am unable to format the logic for my project models in django
I'm working on a student result management app. I have other parts working but the logic of the marks entry and model creations have sent me lost. I need entry for marks for the various subjects for a group of students(students in particular streams for specific exams). A student belongs to a stream which belongs to a class which belongs to a particular school. I've created models for Marks, Subjects, School, Klass, Exam, Stream, Student.

(Data needs to be rendered to HTML) Example: model.py class Book(models.Model): title = models.CharField(max_length=30) author = models.CharField(max_length=30) views.py class BookListView(viewsets.ModelViewSet): permission_classes = (AllowAny, ) template_name = 'booklist.html' queryset = Book.objects.all() renderer_classes = [TemplateHTMLRenderer] pagination_class = BookPagination serializer_class = BookSerializer def list(self, request): queryset = Book.objects.all() serializer = ProtocolSerializer(queryset, many=True) page = self.paginate_queryset(serializer.data) return self.get_paginated_response(page) I can show the paginated item with the codes above. And there are next and previous links in HTML. However, I need page list like [1,2,3,....], not just next and previous. I can view the data on the 3rd page by just click button 3. I need some steps to do this. 1: Retrieve the target page number(I don't know how to do this) 2: Get the data of on that page 3: Render to HTML I hope someone can help me with this.
