NoReverseMatch at /cart/ while adding new item to the cart
I'm setting up a cart app following some tutorial but using my own settings. when I try to add an item or product to the cart it gives me NoReverseMatch at /cart/ Reverse for 'detail' not found. 'detail' is not a valid view function or pattern name. here's codes in my views file: @require_POST def cart_add(request, book_id): cart = Cart(request) book = get_object_or_404(Book, id=book_id) form = CartAddProductForm(request.POST) if form.is_valid(): cd = form.cleaned_data cart.add(product=book, quantity=cd['quantity'], update_quantity=cd['update']) return redirect('/cart/') def cart_remove(request, book_id): cart = Cart(request) book = get_object_or_404(Book, id=book_id) cart.remove(book) return redirect('/cart/') def cart_detail(request): cart = Cart(request) context = { 'cart': cart } for item in cart: item['update_quantity_form'] = CartAddProductForm(initial={'quantity': item['quantity'], 'update': True}) return render(request, 'cart/detail.html', context) and for urls file: urlpatterns = [ path('', views.cart_detail, name='cart_detail'), path('add/<int:book_id>/', views.cart_add, name='cart_add'), path('remove/<int:book_id>/', views.cart_remove, name='cart_remove'), ] -
How to add a situational field to a Serializer?
I'm trying to figure out the best way to handle a situation where a model may have sensitive information that I only want the owner to be able to see. For example the store below: class Store(models.Model): owner = models.ForeignKey(Account, on_delete=models.DO_NOTHING) name = models.CharField(max_length=128) license= models.CharField(max_length=128) menu = models.ManyToManyField(Product) address = models.ForeignKey(Address, on_delete=models.DO_NOTHING, blank=True, null=True) class StoreSerializer(serializers.ModelSerializer): owner = AccountSerializer(read_only=True) menu = ProductSerializer(many=True, read_only=True) address = AddressSerializer(read_only=True) class Meta: model = Store fields = ('owner', 'name', 'menu', 'address', 'license') In this example I want all users to be able to find stores but the license field should only be available to CRUD if the user is the owner of this object. What is the optimal solution in this case? My options so far seem to be: A) Create a separate serializer for the owner type B) Turn license into a SerializerMethodField and provide it optionally from there I'm wondering which is the better practice and if there are other more elegant ways of doing this. -

My website doesnt load the correct css parameters
I'm developing a MOOC application using Django for the back-end and simple html for the front-end. I gave one updated on 'styles.css' to make the face of the site a little friendlier but he simply refuses to use the colors I've decreed. Here u can find my full app. An example, in the /core/templates/base.html file I created a div called footer: ... <div class="footer"> Tâmer MOOC - Uma simples plataforma de ensino a distância </div> ... So, I setup some configs in the /core/static/css/styles.css file, here is the footer stuff (Im really newbie in css so, maybe the error is obvious): .footer { background: #2d3e50; color: #fff; text-align: center; padding: 1em; font-size: 80%; } But when I run the server and go to the site, i see this Basically, the bg color was meant to be #2d3e50 and actually is #111 and the font color was meant to be #fff and actually is #666. And this is for all configs ive done, he refuses do reload the configs. The css settings being displayed are the old ones. -
How does running a test in PyCharm result in an "Model class doesn't declare an explicit app_label" error?
I'm using Django, Python 3.7, and PyCharm 2018.3.5. I'm trying to run a test in PyCharm by right-clicking on the test name and selecting, "Run Test: 'test name'". This results in the following error RuntimeError: Model class appname.models.Label doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. This is the model in question, at the top of my models.py file ... class Label(models.Model): name = models.CharField(max_length=200) def __str__(self): return self.name class Meta: unique_together = ("name",) What is very odd is if I run the tests outside of PyCharm (e.g. at a terminal command prompt using "python manage.py test"), everything runs fine. So the problem would seem to be some misconfiguration with PyCharm. I'm unclear how to attack the problem further. Below is my project directory structure ... appname __init__.py __pycache__ admin.py apps.py fixtures management migrations models.py services.py static templates tests.py views.py manage.py templates venv appname_project -

Why should we create Model fields in Django for MongoDB?
I have worked on RDBMS with Django. I'm familiar with Models, Model fields in Django. We are looking for a better way of storing large documents in database. We came across MongoDB and found that the collections in MongoDB doesn't have a schema to store documents. But I found plenty of tutorials where they mention Model fields when working with MongoDB in Django. I searched a lot for this but couldn't find why they are still mentioning model fields in Models in Django. Why are we still creating Model fields (columns) when there is no specific schema for MongoDB collection? -

Django 2.2 breaks previously working views/urls
Decided to take out Django 2.2 for a spin (project is currently running 2.1.8) and now I can't even get the server to start. I have been maintaining this project for nearly two years and this should be a minor update. The error seems to be related to my views, but I can't find anything in the release notes that has meaningfully changed between 2.1.8 and 2.2. I suspect it may be due to my rather non-standard view system. Instead of a single file called views.py, I use a folder of view files joined by an __init__.py. But again, that's just a guess as the error message does little to point me to my problem.

Django: production app on Heroku cant find templates with "path" urlpattern
I´m having my production site on Heroku. The app can find templates defined with url in the urlpatterns of the urls.py file. Like: url(r'^contactreport/$', views.ContactosView, name="contactos"), But not the ones defined with path.

How correctly set Media files URL for deploying in Django-Rest-Framework
For connecting my idnex.html of React Build folder and Django-Rest-Framework I set re_path in my general urls.py file. urlpatterns = [ path('admin/', admin.site.urls), path('api/', include('userauth.urls')), path('api/', include ('articles.api.urls')), re_path('.*', TemplateView.as_view(template_name='index.html')) ] if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) and here is the settings.py file where I set the storage of media and static files: MEDIA_ROOT = os.path.join(BASE_DIR, 'media_files') MEDIA_URL = '/media/' STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'build/static'), ] STATIC_ROOT = os.path.join(BASE_DIR, 'static_files') STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage' The browser does not show images I think the server try to find the URLs of media files among the react-route URLs If I deploy the project without re-path(.....) the server show the standard DRF page and it seems to be the URLs of media files work fine. Please any help ,if you need more information about code I can post it. Thank you in advance. -
How to manage writable nested serializers with multiple serializers in an unique field?
I'm working on django rest framework with nested serializers and i need support on how to POST an object that can take different type of models.

How to allow user to modify only his data in Django Rest Framework
i'm building simple API with Django 2.1.8 and provide security with Django OAuth Toolkit. I've reached the point where user can use api only after authorization but i want to limit his acctions only to his data. I've built authorization using oauth2 which returns me access token. models.py class Client(AbstractUser): email = models.EmailField( verbose_name='email adress', max_length= 255, unique=True, ) location = models.CharField(max_length=500, default="") is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) objects = ClientManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['location'] def __str__(self): return self.email def has_perm(self, perm, obj=None): "Does the user have a specific permission?" # Simplest possible answer: Yes, always return True def has_module_perms(self, app_label): "Does the user have permissions to view the app `app_label`?" # Simplest possible answer: Yes, always return True @property def is_staff(self): "Is the user a member of staff?" # Simplest possible answer: All admins are staff return self.is_admin views.py class SingleClientView(generics.RetrieveAPIView): queryset = Client.objects.all() serializer_class = ClientSerializer permission_classes = [IsAuthenticated, TokenHasReadWriteScope] Is there any possibility to connect returned token with user model, so every time someone would use API it filter if user matches required data? Or does oauth toolkit automatically and how to acces it? -

Using Amazon S3 to save static files with Django. Collecstatic does not upload files to S3

How to fix AttributeError: 'NoneType' object has no attribute 'id' and self.assertEqual(Item.objects.count(), 1) AssertionError: 0 != 1
I've managed to go up to chapter five of the book Test-Driven Development in Python. I'd like some help to point me in the right direction to solve two errors. I have looked into all the threads of the same errors on Google. But explanations differ from my test case. So I struggle to understand what's wrong with the code below. I understand that the self.assertEqual(Item.objects.count(), 1) AssertionError: 0 != 1 tells me 'id' is not defined. But I don't know where to fix that in Django.

How do I reference the "many" of "one-to-many" relationships in Django/Python?

If I have an "article" object somewhere in my code, how do I reference its ArticleStat object with the greatest elapsed_time_in_seconds? Even doing article.articlestats results in an error so I don't even know how to reference the related ArticleStat objects from my initial object. -
Rendering HTML when request comes from browser or sending JSON dictionary when request comes from mobile
I'm trying to build a backend for an app that has both a web frontend (designed with bootstrap) and a mobile frontend (designed with Flutter). I've been trying to understand the documentation for Django REST Framework about renderers, but I can't figure out how to deal with different types of requests (one from web and one from mobile, for example) without having two different functions for both platforms. Is there a better way to do this than having a flag passed through the request that says whether the app is mobile or web, and returning a Response object or render object depending on that flag's value? -
