Django, sum of values in form, then submit to database
Say for example I have this. Take the input fields, and add via the calculate button. I tried using django-mathfilters inside of my html file, but then I realized that the fields would always be empty beforehand, so nothing would ever be calculated. What is the right approach to this? Do I need to split Final_Result from my book table? Book Price: $10 (input field) Delivery charge: $3 (input field) Delivery type: $5 (input field) Final Result: (result of adding the fields above when user clicks the calculate button [calculate] [submit] submit button will finalize the results and sent the values to the database. This is my model for the table class book(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, ) book_price = models.IntegerField() delivery_charge = models.IntegerField() delivery_type = models.IntegerField() final_result = models.IntegerField() views.py for the form def final_price(request): if request.method == 'POST': form = RequestForm(request.POST) if form.is_valid(): instance = form.save(commit=False) instance.user = request.user instance.save() return redirect('final_price') else: form = RequestForm() args = {'form': form} return render(request, 'final_price.html', args) Model for to allow me to edit the fields in my book module class RequestForm(forms.ModelForm): class Meta: model = book fields = ( 'book_price', 'delivery_charge', 'delivery_type', ) I tried adding them through the … -

I want to serve static files with permissions logic in my django project
So I've been working on a django project. Its a marketplace platform (two kinds of users - buyer & seller) and when a seller uploads files for a buyer, only those two users should have access to the uploaded files. I'm trying to figure how static files can be served with these permissions. I'm not sure if this is relevant but I'm using nginx to serve the static files, so is there a way to add permissions logic in django to serve these static files? -
Python(Django), PHP, Ruby frameworks: How do they handle browser side scripting?
I am quite familiar with javascript frameworks like Angular, React & Vue. Since browsers understand and knows how to run javascript, these frameworks are used for end-to-end web application development. But when we think of non-javascript frameworks like Python(Django/Flask), PHP, Ruby on Rails etc. few questions come to my mind: Do these framework supports only server side scripting in their respective languages (i.e. Python, PHP, Ruby)? When these frameworks send webpage/response to browser and lets say for example the page is having submission form which needs validations, which scripting do they use on browser side? Because browsers don't support Python, PHP, Ruby languages. OR Django/Flask, PHP, RoR programmers also need to know javascript and they got to embed it in pages/responses they send? -
Profile model Data is not saving when I try to create user and Profile simultaneously

How to add Auto increment Field, Which isn't a Primary Key in Django Models
I want to add a field id in my Django Model. The primary key is the email id.

Is it possible to implement Session AND Token Authentication together in DRF?
I'm kind of new with DRF and I am building a website. I've successfully implemented a basic authentication using forms and the code below: def login_request(request): if request.method == 'POST': form = AuthenticationForm(request=request, data=request.POST) if form.is_valid(): username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') user = authenticate(username=username, password=password) if user is not None: login(request, user) return redirect('/user-area/') form = AuthenticationForm() return render(request = request, template_name = "myapp/login.html", context={"form":form}) After logged in, the user is redirected to a page that shows some data about him. My question is: Is it possible to show the user Authentication Token on this page (on browser, with my HTML template)? So the user would be able to just copy the Token and use it in his device to request some data (on another page), without needing of provide his login/password credentials? I'm looking for the both Authentication Method... to allow the user login providing the credentials on his browser AND use only the token on his external device. There is a similar question, but without answers here: DRF both Token and Session Authentication -

Django clean() method not raising exception when form.is_valid() is called
I want to return a custom message based on the error when a user submits a form but I don't know how to catch the exception. I have extended the clean() method to raise some ValidationError's: class EmailChangeForm(forms.Form): email1 = forms.EmailField(label='New Email') email2 = forms.EmailField(label='Confirm Email') password = forms.CharField(label='Password', widget=forms.PasswordInput) def clean(self): cleaned_data = super().clean() new_email1 = cleaned_data.get('email1', None) new_email2 = cleaned_data.get('email2', None) print(new_email1, new_email2) try: user = User.objects.get(email=new_email1) except: user = None if user is not None: raise forms.ValidationError('Email is already in use.', code='inUse') elif new_email1 != new_email2: raise forms.ValidationError('New emails don\'t match.', code='noMatch') return cleaned_data But when i call form.is_valid() it only returns a boolean. I know it's being called because using print will output something to the console. Is it possible to get the custom messages via .is_valid()? -
Alternatives to Django post_save
a question on Django signals, e.g. post_save: My understanding is that object updates caused by a post_save signal fire an additional call on that object's post_save. Taking it a step further, syncing two models via 2 post_save signals calls post_save on one model's object, which then calls post_save on the other model's object, then post_save back on the original, at the least. Is there a way to disable the recursion here? Also, in general, is this actually a pattern that is scalable and endorsed by the Django community? Recently came across this article suggesting overriding model save function, but it seems like that approach isn't viewed positively across Django users either. Is there another way? -

Django ORM Query Multiple Models Reverse Relationship
I have the main model and five sub-models out of five four models have foreignkey relationship and one model has a one-to-one relationship to the main model. I am trying to execute a query on the main model and fetch related records from the sub-model sorted by 'id' and select the first record. I tried multiple ways to achieve this but still, the total operation takes around 20secs to fetch around 6000 records. I would really appreciate any help to efficiently fetch data from these models. Model M: id name status Model SA: m = Foreignkey(M) sa1 Model SB: m = Foreignkey(M) sb1 Model SC: m = Foreignkey(M) sc1 Model SD: m = Foreignkey(M) sd1 Model SE: m = OneToOne(M) se1 I tired select_related, prefetch_related, but still not able to reduce the turn-around-time. After trying different ways, currently, I am using the below, but from that, I get the only records which has data in the sub-models. But I would need to fetch all records from the main model irrespective of data in the sub-models. data = M.objects.exclude( SA=None, SB=None, SC=None, SD=None, SE=None, ) I am looking for output like: {'id': 1212, 'name':'asdasd', 'sa1':'asdasda, 'sb1':'asdasda, 'sc1':'asdasda, 'sd1':'asdasda, 'se1':'asdasda} -

Permanent Superuser Django Docker
So, I have a dockerfile that I run Django via CapRover to run the backend of my website. Amongst the components, I have an admin panel that I log into using a superuser that I've created by ssh-ing into the docker container. The problem is that whenever I change my backend by uploading it as a .tar via CapRover, I have to create my superuser again. My question is, is there any way to avoid this by creating some sort of persistance? Or is there any way of automating this via my dockerfile? Thanks!
