Do I need to clear the prefetch cache after each Django prefetch_related?
Django mentions that this is the way to clear the prefetch cache: non_prefetched = qs.prefetch_related(None) Which you should do since now the values are loaded into memory. One problem I'm finding is that this is even persisting across requests, meaning that the data is still cached even after returning in a separate session. Is this expected behavior, or am I misunderstanding? If this is the expected behavior, does this also mean I have to clear the cache at the end of every view with the call above? -
Tox.ini does not recognize python folder?
I ran into weird issue which I have trouble solving. I have following tox.ini file: [vars] PROJECT = django_project TASKS = tasks --exclude tasks/migrations PAGES = pages -exclude pages/migrations [tox] envlist = py310, flake8, black, mypy [testenv] deps = -rrequirements.txt -rrequirements-dev.txt commands = python manage.py test [testenv:flake8] basepython=python3 deps = -rrequirements-dev.txt commands= python -m flake8 --max-line-length=100 {[vars]PROJECT} {[vars]TASKS} {[vars]PAGES} whitelist_externals = /usr/bin/python3 [testenv:black] deps = -rrequirements-dev.txt commands = black --check --diff {[vars]PROJECT} {[vars]TASKS} {[vars]PAGES} [testenv:mypy] deps = -rrequirements-dev.txt commands = mypy --install-types --non-interactive \ --ignore-missing-imports \ --disallow-untyped-defs \ --disallow-incomplete-defs \ --disallow-untyped-decorators {[vars]PROJECT} {[vars]TASKS} {[vars]PAGES} The black commands works as expected for PAGES, but the commands flake8 and mypy are returning following error: error: unrecognized arguments: pages -exclude pages/migrations Does anyone have any idea what could be causing this? -

How to color value in list with django?
I am using the django framework. And I have a list with values. And the values from that list are displayed on a template. So this is the list: self.list_school_values = [ "12bg00", "Basisschool Vroonestein", "Lohengrinhof 1517, 3438RA NIEUWEGEIN Utrecht", "Lohengrinhof 1517, 3438RA NIEUWEGEIN Utrecht", "mevr. W.M. van den Brink", "030-6037291", "info@vroonestein.nl", "196", "Verdi import B.V.", "dhr. Kees Kooijman", "Koopliedenweg 38 , 2991 LN BARENDRECHT", "verdi@qualitycontrolsystems.nl", ] and the template looks: <div class="form-outline"> <div class="form-group"> <div class="wishlist"> <table> <tr> <th>Gegevens school </th> <th>waardes school contract</th> </tr> {% for value0, value1 in content %} <tr> <td> {{value0}} </td> <td class="{% if value1 == '12bg00' %}red {% endif %}"> {{value1}} </td> </tr> {% endfor %} </table> </div> </div> </div> and css: .red { color: red; } But the value is not colored red. Question: how to color the value from the list red? -
Why is django not showing multiple error messages?
When my form has multiple error messages it only show the first one. Forms.py code: class LoginForm(AuthenticationForm): error_messages = { "invalid_login": _("Incorrect login details. Try again"), "inactive": _("This account is inactive."), } I'm just using the normal Auth form but overwriting the already existing error messages so the message says something different. Template code: <form method="POST"> {% csrf_token %} {{ form }} <button type="submit">Log in</button> </form> When a inactive user tries to login the form returns this: {'invalid_login': 'Incorrect login details. Try again', 'inactive': 'This account is inactive.'} While the user did fill in the right details. And this is the only error that gets shown: <ul class="errorlist nonfield"><li>Incorrect login details. Try again</li></ul> I want it to show either both or the inactive error message since I find that more important to know. -

There seems to be a problem with Django Urls?
When ever I run python manage.py runserver, I get a message in the terminal "Not Found: /base/". I do not have this in my urls to start off with anyways so why am I seeing this? Below is what shows up when I run the server. And my url server is default to "http://127.0.0.1:8000/base/" instead of "http://127.0.0.1:8000". Using the URLconf defined in cric_manager.urls, Django tried these URL patterns, in this order: admin/ manager/ The current path, base/, didn’t match any of these. I tried to restart the termnial, VSCODE, and the webpage, but nothing seems to be working. Its getting a little bit annoying. -
How to display name of table from queryset in django
Trying to get the table name in django, I need it to display the detailview correctly via if statemnet. I have such a view to display class Home(ListView): template_name = 'home.html' def get_queryset(self): qs1 = Book.objects.all() qs2 = CD.objects.all() qs3 = Film.objects.all() queryset = sorted(list(chain(qs1, qs2, qs3)), key=operator.attrgetter('title')) return queryset and it returns to me this [<CD: Music1>, <CD: Music2>, <Book: Some books>] How can I get "CD" or "Book" in this template {% block content %} <div class="row"> {% for object in object_list %} <div class="col-md-3"> <div class="card card-product-grid"> <img src="{{ object.image.url }}"> <a href="{% url 'DetailBook' object.pk %}" class="title">{{ object.title }}</a> </div> </div> {% endfor %} </div> {% endblock content %} At the same time, if it's a bad idea to display detailview and listview and it's done differently, I'd appreciate it if you'd let me know I tried different ways of displaying object.key in a loop but it didn't work very well. And other queryset queries. -

Expanding serialized objects
I have records that represent the amount of money spent on specific expense types: class ProjectExpense: expense_type = models.ForeignKey('ExpenseType') month = models.DateField() value = models.DecimalField(max_digits=10, decimal_places=2) Dollar values are input by quarter, so example entries might look like this: [ Expense Type: Travel Month: 2022-04-01 # Quarter 2 Value: $120,000 ], [ Expense Type: Capital - Hardware Month: 2022-07-01 # Quarter 3 Value: $60,000 ] When I report these entries via my REST API, I'd like to spread the dollar amount throughout the quarter. So, using the first example above, the entries would end up looking like: [ Expense Type: Travel Month: 2022-04-01 Value: $40,000 ], [ Expense Type: Travel Month: 2022-05-01 Value: $40,000 ], [ Expense Type: Travel Month: 2022-06-01 Value: $40,000 ], In this example, one line item has been expanded into three, spreading the cost equally. Is this kind of thing possible using the Django Rest Framework? Serializers only ever seem to operate on one object at a time, so they feel like the wrong thing to use. Of course I could roll my own view, but I'd like to take advantage of the pagination capability that DRF offers. Is there a fairly simple solution for a … -
How to properly filter model to update Plotly graph in Django?

Dependent and Dynamic Dropdown form in js
Hey so I am trying to to make both a dynamic and dependent dropdown form. Essentially I want the second form to be dependent of the first forms option, and when you add a new form field I want it to generate a new div form with a different ID and and the option in the first form removed from the second and then third form. In the case the user only selects on form and doesn't decide to add a second or a third, I would like to still submit a NULL value through the form's that aren't submitted.

create pdf with each post django
Currently working on a django social media application where next to posting every post to the feed, the information of each upload should create a pdf document, containing caption, image, created_at and image_id. I´ve put the canvas into the upload functions, so that both will be created on the same click. So far, i get a pdf (can't get the attributes from the post into the pdf tho) and the post is uploaded just fine. How do I get the posted data into the pdf? And how do save that pdf to a folder within the project instead of starting an automatic download? The user should not be able to notice the pdf converting. It is just for back office - but very necessary due to the social media website being a part of a big installation. So how do I get these pdfs? Here is the code: views.py def upload(request): if request.method == 'POST': #user = request.user.username image = request.FILES.get('image_upload') caption = request.POST['caption'] new_post = Post.objects.create( image=image, caption=caption) new_post.save() #create pdf buffer = io.BytesIO() p = canvas.Canvas(buffer) p.drawString(100, 100, "Hello world.") p = request.FILES.get('post_pdf') p.drawText('caption') p.drawImage('image') p.showPage() p.save() buffer.seek(0) return FileResponse(buffer, as_attachment=True, filename='hello.pdf') return redirect('/') else: return redirect('/') models.py … -
Set a public/base URL for a Django which is behind a proxy
I've got a Django app which sits behind an API Gateway (Gravitee more specifically). In the API Gateway there is an API set up with the endpoint https://mycompany.com/myapi/v1 which points to the Django app, acting as a proxy. So a user would request https://mycompany.com/myapi/v1/resource and get a response from the Django app. The app uses Django REST framework (DRF) which returns URLs in its responses: [ { "url": "http://inner-host-machine:1337/v1/resource/1", "id": 1, "name": "Name 1" } ] But as you can see it is returning the URL of the host the Django app is on, not the API Gateway URL. I would like that URL to be https://mycompany.com/myapi/v1/resource. I tried setting the Host header on the proxy to mycompany.com but the results in the URL https://mycompany.com/v1/resource which is not correct. Setting the Host header to mycompany.com/myapi does not work because it's not a valid host. The domain name provided is not valid according to RFC 1034/1035. Is there a setting in Django or DRF which sets a public or base URL? So all URLs in responses would start with that URL. -
Using models between an App and API app in Django Rest framework

Why the changes I made in the Django model not being reflected in the html form?
I have a field named 'amount' of type Floatfield. I changed it to DecimalField and ran makemigrations and migrate commands and it successfully generated 0002_alter_expense_amount.py file.
