Django doesn't raise ValidationError on ModelChoiceField (widget RadioSelect) if user didn't select any choice
I have a form that contains a ModelChoiceField poller_category class PollersForm(forms.Form): # Poller Category poller_category = forms.ModelChoiceField(widget=forms.RadioSelect(attrs={ 'class': 'poller-category-radio', }), queryset=Categories.objects.all().order_by('poller_category'), label='Select a Category') which is rendered as follows: <!-- Poller Categories --> <div class="fieldWrapper"> <div class="label">{{ form.poller_category.label_tag }}</div> <div class="category-ctn"> {% for category in form.poller_category %} <div class="category-wrapper">{{ category }}</div> {% endfor %} </div> </div> Now if the user doesn't select any category and tries to submit the form, nothing just happens. That actually means that the form is valid, doesn't it? If so, why doesn't it trigger the redirect? Also If I select a choice and submit, redirect is called, but the category isn't populated in the DB. # create a form instance and populate it with data from the request: form = PollersForm(request.POST) # check whether it's valid: if form.is_valid(): # process the remaining data in form.cleaned_data as required poller_text = form.cleaned_data['poller_text'] poller_category = form.cleaned_data['poller_category'] poller_choice_one = form.cleaned_data['poller_choice_one'] poller_choice_two = form.cleaned_data['poller_choice_two'] # Get the user created_by = request.user # Save the poller to the database p = Pollers(poller_text=poller_text, poller_choice_one=poller_choice_one, poller_choice_two=poller_choice_two, poller_category=poller_category, created_by=created_by) p.save() # redirect to a new URL: return redirect(poller_success) # if a GET (or any other method) we'll create a blank form else: form = … -

Django Authentication Via Http With Websockets
I'm doing this - Load single page application - an apollo client is initialised with a websocket and http link. This happens when the user is logged out, let's say. The user then logs in without a page reload. The graphql response now contains the session cookie. Problem - whilst subsequent http requests include the session cookie the websocket connection does not. How do people solve this problem? I'm guessing on the client I could either make all communication with the server via websockets, or, create a new apollo client upon successful sign in and use this for subscriptions. Is it possible though to somehow pass the session cookie to the websocket already established on the client? I'm using django channels. I know it has a login function but this is logging in the user who has made a request via websockets I believe. This is for a chat app. But websockets are obviously common within most web apps. For example a notification system. Of course with most web apps you'd use http and websocket. So I'm wondering how people go about this. -

How to look up a field value using foreignkey in Django

A camera can have many BaseImages but each BaseImage can only match to one Camera. What I get in the name is something like "base_images/<django.db.models.query_utils.DeferredAttribute object at 0x7f6006bd9b70>/20/camera_1.jpg". What do I need to change to get the slug field value as part of the filename ? -
Getting data from parent to child - FE or BE, how?
I'm learning Django and React. I'm trying to get some data from Order to TranspOrder. Order -< TranspOrders In the model Order (orders/model.py), I have a field total_allowed_amount and a function get_total_remaining_amount(self), which calculates total_allowed_amount - total_consumed_amount and returns the result. In OrderDetailSerializer I have a field total_remaining_amount (source= "get_total_remaining_amount" - I assume this means it gets the dafa from that function). So, in the frontend I have OrderDetails.js (Order) React component which displays the two fields total_allowed_amount and total_remaining_amount. Now I need to display these two fields also on TranspOrderDetails.js (TranspOrder), but can't figure out a way to do it. Not even sure if it is correct to do it via back- or frontend. This is very annoying, as it seems to be a very basic thing. I've tried writing functions in the model TranspOrder (transporder/models.py) to bring these into this model from Orders, so I can then access them from the FE (I think that creating same fields for them in this model is not a good idea): def get_order_total_allowed_amount(self): if not self.order.total_allowed_amount: return None return self.order.total_allowed_amount def get_order_total_remaining_amount(self): if not Order.total_allowed_amount: return None return self.get_total_remaining_amount(Order) I've also tried to import these from OrderDetails.js into TranspOrderDetails.js, as such: … -

Problem with database , how delete field from db ? [Django]
I would like to delete a field from one of the tables in my database but I'm having some problems. (The project I'm working with uses the Django framework) I deleted the fields from the table in the models.py file, then I updated the database from the terminal with the commands "python manage.py makemigrations" and then "python manage.py migrate", (which tell me that there is nothing to be updated in the database). The problem is that those fields are still present in the table if I log into the database ... where am I wrong? -

Why does Django refuses http connection on a specific route, but on other routes http works properly?
I have a Django project. Its routes are: urlpatterns = [ path('admin/', admin.site.urls), path('projects/', include('projects.urls')) ] When I was preparing the project for production, I set SECURE_HSTS_SECONDS to 3600 seconds. Right after this, I got this error. I tried to set this variable to 1 second, but It didn't help. Also, I tried to remove this variable, but my app still doesn't work. I also noticed, that when I hit the https://localhost:8000/projects/ route, Django automatically sets HTTP to HTTPS and even when I change HTTPS to HTTP manually, It's still not going to work. However, it works if I change my route to something different, like http://localhost:8000/works/. I already tried to clear cache in google chrome, head to chrome://net-internals/#hsts and delete localhost from security policies. And I even updated my SECRET_KEY. Now I think, the only way to solve this issue is to recreate the project, but I can't do this, because all the data will be deleted. So what am I doing wrong? -
