Django templates url - differentiate between same url names
in my application I've got a view called download_document which works fine using {% url 'download_document' some_id %} . Installing a 3rd party app into the virtual environment cause trouble because this app has also the download_document view (also accepting one ID parameter) with the same urlname. If I'd like to use both with this name, can I somehow make the difference between them? For instance using both cases in the same template file? Python: 2.7 Django: 1.11.16 Debian . -
Two different table (nested loop?) in django template
Could you help me, please? I have two tables and I want to display different data from them on the template, here is my code: models.py: from django.db import models from suppliers.models import Company class Product(models.Model): product_name = models.CharField(max_length=200, blank=True, null=True) product_ean = models.CharField(max_length=50, blank=True, null=True) def __str__(self): return f'{self.product_name} {self.product_ean}' class Product_company(models.Model): product_name = models.ForeignKey(Product, null=True, on_delete=models.SET_NULL) company_name = models.ForeignKey(Company, null=True, on_delete=models.SET_NULL) product_price = models.CharField(max_length=50, blank=True, null=True) def __str__(self): return f'{self.product_name} {self.company_name}' views.py: from .models import * def products_list(request): product = Product.objects.all() product_company = Product_company.objects.all() context = { 'product': product, 'product_company': product_company, } return render(request, 'products/products_list.html', context) products_list.html: <table class="table"> <thead> <tr> <th>Termék neve</th> <th>Termék EAN száma</th> <th>Kihez tartozik?</th> <th>Termék ára</th> <th>Műveletek</th> </tr> </thead> <tbody> {% for i in product %} {% for x in i.product_company_set.all %} <tr> <td>{{ i.product_name }}</a></td> <td>{{ i.product_ean }}</td> <td>{{ x.company_is_registered }}</td> <td>{{ i.company_name }}</td> <td>{{ i.company_give_list }}</td> </tr> {% endfor %} {% endfor %} </tbody> </table> Unfortunately, nothing display in the Product_company table, what could be the problem?

Should you access cleaned_data directly in views or have a method belonging to the given form that handles working with cleaned_data?
I started experimenting with django few afternoons ago and I have an app with a custom form in which I authenticate user the following way: if form.is_valid(): username = form.cleaned_data['username'] password = form.cleaned_data['password'] ... work with username and password ... However, I also read on some webpage (witch I no longer have in my search history :/) that you should not access cleaned_data like that and that it is better to hide using of cleaned_data to a custom method. And do something like this: if form.is_valid(): form.process() I don't think that it should matter much. Nonetheless, I'm curious which way is more preferable and django-like. Thanks! -
Django Improper URL NoReverseMatch

Save data from form into 2 models using .save()
I'm creating a registration and login app with Django. I get the data using a form and POST. I want to save the form data into two Django models: class Customer(models.Model): username = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE) name = models.CharField(max_length=200, null=True) email = models.CharField(max_length=200) def __str__(self): return self.name And the Django User model. forms.py from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User from .models import * class CreateUserForm(UserCreationForm): class Meta: model = User fields = ['username', 'email', 'password1', 'password2'] Registration View.py def registerPage(request): form = CreateUserForm() if request.method == 'POST': form = CreateUserForm(request.POST) form2 = Customer print(form) if form.is_valid(): form.save() user = form.cleaned_data.get('username') name = form.cleaned_data.get('username') email = form.cleaned_data.get('email') form2.save(user, name, email) messages.success(request, 'Account was created for ' + user) return redirect('login') context = {'form': form} return render(request, 'login/register.html', context) Now my question is, how do I save the form data into the user models AND save the data(user, name, email) into the Customers model? I tried using form2.save(user, name, email) but i get an error message: 'str' object has no attribute '_meta' Thank for any help! -

VS Code does not see sqlite3
I am building a website using Django and wanted to inspect my database using command: python manage.py dbshell however surprisingly I got CommandError: You appear not to have the 'sqlite3' program installed or on your path. I am using VS Code for my project and got the error in command prompt terminal of VS Code. I am saying surprisingly because I have already created my models before with commands python manage.py makemigrations and python manage.py migrate. These commands also don't work right now. It is impossible that sqlite3 is not installed because python installs it inherently. I assume PATH variable is also not an issue as I added it and can run sqlite3 outside of VS Code if I open command prompt from the start menu of windows. What can be the reason of this corruption/problem and how can I fix it ? This is screenshot of start menu command prompt : This is screenshot of VS Code : -

React - Can't get my Axios to POST to my backend URL? Backend URL's work just fine via tests
I'm testing out a new user registration form. I've used this exact same form set-up for my login page, it works just fine, users can login with their credentials and connect to the backend. However, this time when I try to reflect the same method onto my registration form, I'm getting a forbidden 403 error from django. I've tested out the URL path using Postman and Swagger, they both work fine (without headers). Which is why you see the 201 white response in my terminal above. The 403 only occurs when I try to register via my React Frontend app. Here is my Axios post request: const onSubmit = (data, e) => { console.log(data); axiosInstance .post(`user/register/`, { email: data.email, username: data.username, first_name: data.first_name, last_name: data.last_name, password: data.password, subscribed: data.subscribed, }) .then((res) => { history.push('/login'); console.log(res); console.log(res.data); }); }; Here is the code of my React registration form. export default function SignUp() { const { register, control, errors: fieldsErrors, handleSubmit } = useForm() const history = useHistory(); const initialFormData = Object.freeze({ email: '', username: '', first_name: '', last_name: '', password: '', subscribed: false, }); const [formData, updateFormData] = useState(initialFormData); const handleChange = (e) => { updateFormData({ ...formData, ...e, // Trimming any … -

HTML: <form method="POST" class="post-form"> {% csrf_token %} <div class="col-md-12"> {% for value, name in form.fields.payment_option.choices %} <div class="radio"> <label><input type="radio" name=paymentMethod id="{{ name.id }}"class="mr-2">{{ name }}</label> </div> {% endfor %} </div> </div> <div class="form-group"> <div class="col-md-12"> <div class="checkbox"> <label><input type="checkbox" value="" class="mr-2"> I have read and accept the terms and conditions</label> </div> </div> </div> {% if name in form.fields.payment_option.choices == stripe %} <button type="submit" class="btn btn-primary py-3 px-4" action="{% url '' %}">Place an order</button> {% endif %} </form> urls.py: urlpatterns = [ path('', views.index, name='index'), path('shop/', views.shop, name="shop"), path('about/', views.about, name="about"), path('blog/', views.blog, name="blog"), path('contact/', views.contact, name="contact"), path('checkout/', views.checkout, name="checkout"), path('cart/', views.cart, name="cart"), path('product-single/<slug:slug>/', views.productpage, name="productpage"), path('add-to-cart/<slug:slug>/', views.add_to_cart, name="addtocart"), path('remove-from-cart/<slug:slug>/', views.remove_from_cart, name="removefromcart"), path('payment/<payment_option>/', PaymentView.as_view(), name='payment') ] -
Django, google app engine, bucket No 'Access-Control-Allow-Origin'
Hello i've a problem that i can't solve. Now i've a simple django project and i'm close to finishing. a few days ago i upload my static files and media files to google cloud sql-bucket. Normally everything was fine for media files but when i upload static files something started to happens.

Class based views
I'm experimenting with class based views as I've not worked with them yet. I'm also pretty new to Django. I'm having trouble correctly using slug or pk and setting up my URL's in my products app. My Project level urls.py: from django.conf import settings from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('accounts/', include('allauth.urls')), path('', include('home.urls', namespace='home')), path('products/', include('products.urls')), path('checkout/', include('checkout.urls')), ] urls.py(product app): from django.urls import path from .views import ItemDetailView urlpatterns = [ path('', ItemDetailView.as_view(), name='products'), ] views.py(products app): from django.shortcuts import render from django.views.generic import DetailView from home.models import Item def products(request): context = { 'items': Item.objects.all() } return render(request, "products/products.html", context) class ItemDetailView(DetailView): model = Item template_name = "products/product.html" I have tried adding <slug>/ to the products url pattern but that doesn't work. I'm pretty sure I need to adjust my url's but I'm not sure how. -
