Framework, front-end, back-end, full stack? Or not to learn a framework?
I have several questions. I am a student and am training in web development. I have practically finished developing my first site which uses HTML, CSS, Javascript, PHP and MySQL. I want to acquire a certain ease in web development, but in theory this will not become my job, nor my daily life. I am about to start a bigger project (several months of development to be expected) because I am starting to be confident and have the capacities of my ambitions (not crazy either). Basically I'm more Python, not web development. So I would like to know if it is important to learn a framework? Especially since not wishing to be professionalized, therefore not specialized in front-end or back-end, I would prefer to solidify myself in full-stack knowledge for the moment. I have heard of Symfony (PHP), Node.js (JS), Bootstap (JS), etc ... But these are specialized front or back frameworks. If I have to learn a framework I would prefer it to be full-stack. And I ask myself the question if Django will not be what I need since it is a Python web framework. But is it good? Is it "full-stack" or just back-end? Isn't it a … -
Django querryset annotate and aggregation
I have a few models for which I am trying to create custom managers and query sets. In this example, I want to get the total paid amount throughout all the orders for each customer. But unfortunately, I will keep getting the wrong values, why?! Here is an example of some of my models: class customer(models.Model): name = models.CharField(max_length=100, blank=False, null=False) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="customer") objects=CustomerManager() #My customer manager class order(models.Model): paid = models.DecimalField(default=0.00, max_digits=30, decimal_places=2) customer = models.ForeignKey(customer, on_delete=models.CASCADE, related_name="order") class order_item(models.Model): quantity = models.PositiveIntegerField(default=0, null=False) price = models.DecimalField(decimal_places=2, max_digits=30, default=0.00) product = models.ForeignKey(product, on_delete=models.CASCADE, related_name="order_item") order = models.ForeignKey(order, on_delete=models.CASCADE, related_name="order_item") Here is my manager: class CustomerManager(models.Manager): def get_queryset(self): return CustomerManagerQuerry(self.model, using=self.db) def get_customer_stats(self): return self.get_queryset().customer_stats() Querryset: class CustomerManagerQuerry(models.QuerySet): def customer_stats(self): table = self.annotate(total_paid=Sum('order__paid', output_field=FloatField())) return table.values('total_paid') My goal is to get the summation of paid attributes throughout the orders for the customer. When the order object includes only one order_item the querryset outputs the correct value, But when the order object contains more than one order_item I will get the wrong result. For example when I run the code customer.objects.get_customer_stats() for only one customer who has only one order with the paid amount of 10.0, I will … -

Django dj-rest-auth + react: What is the best way to activate your email when ACCOUNT_EMAIL_VERIFICATION = 'mandatory'?
I'm currently building a django & dj-rest-auth + react project and have my allauth ACCOUNT_EMAIL_VERIFICATION = 'mandatory'. Currently and by default, the email activation link can only make a GET request to dj_rest_auth.registration.views.VerifyEmailView (source code) that only accepts a POST request with the activation key as a body param: Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [example.com] Please Confirm Your E-mail Address From: webmaster@localhost To: firstlast@email.com Date: Sun, 04 Apr 2021 09:56:05 -0000 Message-ID: <161753016543.13016.12022069896332406678@DESKTOP-LFBEG3D> Hello from example.com!

Django Subdomains
I want to create a mutitenant site with subdomains. Meaning, users will sign up with email, password and company name. Although, I am still experimenting with the email. Upon register, they will be redirected to a subdomain like company_name.domain.com. Right now, I am using the package Django-Subdomains I have setup as specified in their doc. But I dont quite get how to set up the views. For instance, my register view is this class RegisterStaff(View): template = 'account/register.html' def get(self, request, ): register_form = StaffRegisterationForm() context = { 'register_form': register_form, } return render(request, template_name=self.template, context=context) def post(self, request): register_form = StaffRegisterationForm(request.POST) if register_form.is_valid(): staff = register_form.save() password = register_form.cleaned_data['password1'] email = register_form.cleaned_data['email'] print(dir(request)) my_user = authenticate(request, email=email, password=password) login(request, my_user, ) request.subdomain = request.user.email print(request.subdomain) return redirect('account:dashboard', subdomain=request.subdomain) else: print(register_form.errors) return HttpResponse('form is invalid') and I have my dashboard vies below. class Dashboard(View): template = 'account/dashboard.html' def get(self, request): try: staff = Staff.objects.get(email=request.subdomain) except Staff.DoesNotExist: raise Http404 Normaly, I would thought that after registration, I should be redirected to email.domain.com.

Django Redirect to previous page, if user is not allowed to access page
I have created a custom decorator to restrict access to a view based on an user's group. If a user is not allowed to access the view he/she gets redirected to my landing page '/' (in code below)...

login_required does not work with firebase auth
I have a login page with authenticates the user using the built in Django authentication. However when I use firebase authentication to authenticated a user, the @login_required decorator for my other pages does not allow the user to access those pages (even the user is logged in using the correct credentials). I followed a tutorial from here https://www.youtube.com/watch?v=8wa4AHGKUJM My login views.py using django authentication: email=request.POST.get('email') passw=request.POST.get('pass') user = authenticate(request, username=email, password=passw) if user is not None: login(request, user) return render(request,"pick.html") else: message="Invalid credentials. Try again." return render(request,"login.html", {"msgg":message}) My login views with firebase authentication: email=request.POST.get('email') passw=request.POST.get('pass') user=auth.sign_in_with_email_and_password(email,passw) usercheck = auth.get_account_info(user['idToken']) usercheckjson=json.dumps(usercheck['users']) userjsonload=json.loads(usercheckjson) if userjsonload[0]['emailVerified'] == False: message="Please verify your email before login!" return render(request,"login.html", {"msgg":message}) else: #login(request, user) <-- this does not work session_id=user['idToken'] request.session['uid']=str(session_id) return render(request,"pick.html") Any suggestions on how i can get this to work, or should i just use the built in Django authentication? -
Django channels + Daphne + Nginx, path not found only for wss, not ws
A summary of my question: I am deploying websocket with django channels. When I use ws (without SSL), everything works well. But when I request using wss (with nginx re-configed), it shows the error Not Found: /ws/rider/mission/ Here are some details: I have added path /ws/ for both 80 and 443 ports From the console of Daphne, I can see both requests, as shown in the figure below. Therefore, I think my Nginx is correctly forwarding both 80 and 443 requests. But from this figure, I can find that, for this same route "/ws/rider/mission/", the wss request cannot be found, but ws request runs well. Here is my aswi config application = ProtocolTypeRouter({ "http": django_asgi_app, "websocket": Oauth2AuthMiddleware( URLRouter( websocket_urlpatterns = [ url(r'ws/rider/mission/', consumers.RiderConsumer.as_asgi()), ] ) ), }) I don't know where the bug comes from, it is between Nginx to Daphne, or Daphne to Django channels or in Django channels itself. Thanks! -

How to bind a django form to an object instance
I come from DRF background so please already assume that I might be getting something wildly wrong here. I am trying to use Django Form as a sort of proxy for DRF serializers. As in, when I fetch an object, I can quickly render it back, and I can of course accept POST requests and store them. What I can't seem to find is how do I use my object instances to process them with forms. Here's my form: class ProfileForm(ModelForm): class Meta: model = UserProfile fields = ('name', 'profile_pic') The actual model: class UserProfile(models.Model): user = models.OneToOneField(CustomUser, null=True, on_delete=models.CASCADE) name = models.CharField(max_length=200, null=True) profile_pic = models.ImageField(upload_to='profile_image', null=True, blank=True) def __str__(self): return str(self.user) Now, in my view, I'm doing something like this: from django.forms import model_to_dict profile = request.user.userprofile form = ProfileForm(model_to_dict(profile)) return render(..., form) Is this even the right approach? Besides, the problem is that my form doesn't seem to handle the profile_pic field properly (i.e. the img src field in the from html is just __). Ideally I would want to build the form from the object instance itself, but that also doesn't work. form = ProfileForm(instance = profile) is nethier bound, nor valid form = ProfileForm(UserProfile.objects.all()[0]) is … -
How to apply django-filter after SerializerMethodField modified values?
I feel stuck with the following issue: I added django-filter to my django-rest project to allow filtering by contract's signing status field. The problem is that my contract_signing_status has only 2 possible DB values: SIGNED, NOT_SIGNED. However, I use a SerializerMethodField which internally accesses a user model from the request and returns different values, eg: "WAITING_FOR_ME", "WAITING_FOR_OTHRS". The problem is that the django-filter works on the query-set. As a result, if I set those values: "WAITING_FOR_ME", "WAITING_FOR_OTHRS" as my query params, I keep getting an empty response list, because my model does not define those values... I would like to apply django-filtering on the serializer.data, not on the query-set, because values are modified after the serializer serialized that query set. Is it possible? I thought about creating a property in my model. But properties can't accept additional arguments, like User for example. -

Here are my models class Marks(models.Model): klass = models.ForeignKey(Klass,on_delete=models.SET_NULL,null=True,blank=True) stream = models.ForeignKey(Stream,on_delete=models.SET_NULL,null=True,blank=True) mark = models.IntegerField() class Klass(models.Model): name = models.CharField(max_length=20) The view. def ResultsView(request): query = request.GET.get('klass') if query: queryset = (Q(klass__name__icontains=query)) the_Student = Marks.objects.filter(queryset).distinct() all_results = {'the_Student':the_Student,'query':query} else: all_results = {} return render(request,'exams.html',all_results ) The form template <form action="{% url 'search_marks' %}" method="GET"> <div class="input-group"> <input class="" style="flex:50%" type="text" name="klass"> <button class="btn btn-primary" type="submit"></button> </div> </form> The url path('search_m',ResultsView,name='search_marks'), I try getting the results here {% for mark in the_student %} {{ mark }} {% endfor %} When I print the_student from the view it gives <QuerySet []> When I try queryset = (Q(mark__icontains=query)) brings an answer
