suppress form field errors in Django
I have my form (code below) - it's working perfectly. But it's showing the form field errors, even before it's been submitted (on page load!). Is there a way to supress the errors, if the form hasn't been submitted? <form method="post"> {% csrf_token %} {% for field in form %} <p> <font color = 'white'>{{ field.label_tag }}</font> <br>{{ field }} {% if field.help_text %} <small style="color: grey">{{ field.help_text }}</small> {% endif %} {% for error in field.errors %} <p style="color: red">{{ error }}</p> {% endfor %} </p> {% endfor %} <button type="submit">Sign up</button> </form> -
Testing a custom auth backend with Django RestFramework
I created a custom authentication backend for my DRF application. I can't figure out how to test it. Calling the client.post calls my authenticate function (cause that's in my view) But I need to mock an internal method in my ModelBackend. Kinda confused how to go about this? View: class Web3UserToken(APIView): authentication_classes = [] permission_classes = [] def post(self, request, **kwargs): public_address = request.data["public_address"] web3 = Web3Backend() user, token = web3.authenticate(request) if token: return JsonResponse({'token': token}) else: return Response({'message': 'Missing token'}, status=400) Test: class TestWeb3AuthBackend(APITestCase): def setUp(self): #TODO: set up test user self.client = APIClient() #self.factory = APIRequestFactory() def test_authenticatepasseswithexistinguser(self): self.user = Web3User(public_address=TEST_PUBLIC_ADDRESS) auth_backend = Web3Backend() import ipdb; ipdb.sset_trace() request = self.client.post('/api/token/', {'public_address': TEST_PUBLIC_ADDRESS, 'nonce': '0xsomething_random'},follow=True) with mock.patch.object(auth_backend, '_check_nonce', return_value=True) as method: token, user = auth_backend.authenticate(request) self.assertTrue(token) self.assertTrue(user) -

Django Gmail auth fails despite correct credentials
My sending mail from django through gmail suddenly stopped working. It was working fine for over a year now, so I assume my basic setup should still be fine. The Google Account in question has 2FA enabled and the password used in the config below is a generated app-password, not the main accuont password. I already logged into Gmail via browser and checked that it hasn't been locked and that it isn't over quota. settings.py EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_USE_TLS = True EMAIL_PORT = 587 EMAIL_HOST_USER = '<MY-MAIL-ADDRESS>' EMAIL_HOST_PASSWORD = '<PASSWORD>' DEFAULT_FROM_EMAIL = '<MY-MAIL-ADDRESS>' I already verified my credentials by using the command below: (ofc shell expansion doesn't work i just pasted the output of the command at that location) $ openssl s_client -connect smtp.gmail.com:587 -starttls smtp >AUTH PLAIN $(echo -ne '\0MY-MAIL-ADDRESS\0PASSWORD' | base64) >235 2.7.0 Accepted However, if I try to use send_mail it bounces: In [1]: from django.core.mail import send_mail In [2]: send_mail('Subject', 'This is a test message', 'MY-MAIL-ADDRESS', ('recipient@address.com',)) (Output shortened) SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted.

Can security vulnerabilities in npm packages be of concern for a ReactJs/Django website?
I am developing a website with React.js frontend and Django backend. After updating all npm packages to their newest versions and performing npm audit fix, I still get the following message from npm audit: found 14 vulnerabilities (8 moderate, 5 high, 1 critical) run `npm audit fix` to fix them, or `npm audit` for details I wonder whether I should be concerned about these vulnerabilities, given that they concern only the frontend? When I wrote the backend, I always assumed that an ill-intending user can substitute the frontend and submit any request whatsoever to the backend. -

Django 3.2 - querie multiple Models in view (SQL comparison)
I'm quite new to django and have problems with the ORM and the view-queries. We have already migrated and synched some Models from our productive DB to the django DB, but I have problems with connecting two Models to each other. e.g. models.py: class SsdgSendung(models.Model): sdg_sdgid = models.CharField(primary_key=True, max_length=30) sdg_konz = models.CharField(max_length=12, blank=True, null=True) class Meta: db_table = 'ssdg_sendung' class SsdaSdgadr(models.Model): sda_sdgid = models.ForeignKey(SsdgSendung, on_delete=models.CASCADE, blank=True, null=True) sda_satid = models.CharField(max_length=4, blank=True, null=True) class Meta: db_table = 'ssda_sdgadr' unique_together = (('sda_sdgid', 'sda_satid'),) Sample Data SsdgSendung: sdg_sdgid = BL-1237781-BL-1 sdg_konz = 009874 SsdaSdgadr: sdg_sdgid = BL-1237781-BL-1 sda_satid = IV sdg_sdgid = BL-1237781-BL-1 sda_satid = CN How should the correct "django"-query look for this equivalent SQL: SELECT * FROM SsdgSendung inner join SsdaSdgadr on sdg_sdgid = sda_sdgid and sda_satid = 'IV' WHERE sdg_konz = '1234' I tried this, but I don't get any result on the template: Sendungen = SsdgSendung.objects.filter(sdg_konz = current_user_konz).order_by('-sdg_datum').prefetch_related('sda_sdgid') template {% for la_item in SDG_Overview %} <tr> <td>{{ la_item.sdg_sdgid }}</td> <!-- works well --> <td>{{ la_item.sda_satid }}</td> <!-- don't work --> </tr> -
Django How to connect in local network to my chatt app (channels and redis)
I've implemented the Stein example! https://codewithstein.com/django-realtime-chat-app-tutorial-simple-django-tutorial-with-channels-and-redis/ It works! However, only on my computer! If I try to connect to the local network from another computer, nothing comes out. Earlier, when it was just WSGI, I connected. I think there is also docker involved.

Error with authentication (Django Rest Framework + JWT Auth)
I've been working on my first Django Rest Framework project and I'm having some trouble getting my JWT authentication to work properly. Upon logging into my (React) app, everything works as intended, but when coming back to the app after several hours and doing something in the site that requires authentication, I get the following error instead of the token being refreshed or redirected to my login screen. I'm totally new to authentication, and my code for my JWT Auth is taken from this tutorial, so I'm not completely sure if I've goofed something up or if the tutorial code isn't working properly. I suspect the issue is on the front-end, so here is my axios file where I handle the token refreshes (again, taken from the tutorial code) https://github.com/aesakof/gas-app-v2/blob/main/react-frontend/src/axios.js One issue that is probably notable and that I changed from the tutorial's code is that on line 9 of that file, I changed it to "Bearer " from "JWT " as with JWT I was getting not authorized errors when making requests. As I said I'm very new to JWT and working with authentication in general, so any help would be greatly appreciated! -
How do I go about putting my image classifier in a django server, so various appliances can access it?
I recently created an image classifier for an application, but it turned out to be a way larger of a file than I anticipated, so I looked up on various ways to find a way of compressing it, but that was in vain. So I thought of creating a django server where I could store this classifier, which I could then access with any device. I looked up tutorials, on exactly what I want, but they were all just full django tutorials. So im kinda stuck at this point, so can someone help me with what im exactly supposed to learn/do? Thanks! -
Django Rest Framework - An invalid form control with name='' is not focusable
I've been working with DRF HTML & Forms. I've encountered an issue while playing with it, and I was wondering if that has already happened before. The issue is related to this topic in Stack Overflow. Basically, I'm capable of rendering the form with the prepopulated data, but when it comes to sending the PATCH request to update. I get this: An invalid form control with name='name' is not focusable. An invalid form control with name='jobTitle' is not focusable. An invalid form control with name='salary' is not focusable.

I want to simulate/mimic an "external API" which will send certain responses to my Django project?
I am creating a web application for data visualizations and analytics. I am using Django for that purpose. Now the problem is that, in normal circumstances, this project will take its data (for visualizations purposes) from an external API owned by someone else. And for me to access that API I need to prove my identity and go through many formalities. To avoid this time-gap, I want an app to mimic those external APIs. Basically I want to tell the mimic to throw certain Responses on certain API endpoints. I heard that "Postman" is good for the purpose but don't have any idea even if it will help me. I'm also open to any alternatives, if any. P.S. I'm new to all this web-app stuff so I have no idea If my question is valid. Im working on Windows 10 platform Also this is an educational project by the way. It is not meant for any profit. -
Django: filter ManyToManyfield of all objects in QuerySet
I basically want to do something like this: I want a distinct list of all products from all completed orders, but I want to save/annotate? the order reference('refCode') to the Product object. Order.objects.filter(is_completed=True).order_by('-date_created').products.all().filter(dlLocation__isnull=True).distinct() Notice the ".products.all()". Unfortunately this is no valid code. So my solution was to make 2 seperate querysets like so: completedOrders = Order.objects.filter(is_completed=True).order_by('-date_created').values_list('refCode', 'products', named=True) #<QuerySet [Row(refCode='7822788', products=307691), Row(refCode='7822788', products=307905) Row(refCode='4083860', products=307874)]> downloads = Product.objects.filter(topicID__in=completedOrders.values('products')).filter(dlLocation__isnull=True).distinct() #<QuerySet [<Product: product12>, <Product: product43>, <Product: product35>> How can I insert a Product object on its matching topicID in completedOrders Row dict? The result could be something like this: #<QuerySet [Row(refCode='7822788', products=<Product: product12>), Row(refCode='7822788', products=<Product: product43>) Row(refCode='4083860', products=<Product: product35>)]> Order models.py: class Order(models.Model): refCode = models.CharField(max_length=15, unique=True, primary_key=True, default=generateOrderRefCode) products = models.ManyToManyField(Product) is_completed = models.BooleanField(null=False, default=False) Product models.py: class Product(models.Model): topicID = models.IntegerField(null=False, unique=True, primary_key=True) dlLocation = models.CharField(max_length=200, null=True, blank=True) Excuse me for my bad explanation and grammar faults, this is the first time I have to ask a question to StackOverflow and my head is basically broken from working on this project too long, or I am going crazy lol. Thank you in advance and I wish u a life filled with love and joy <3 -
Form is invalid but no errors

If that is not the problem then I am lost. -

How to disable cookies for all-auth cookie in safari
I implemented social login in django. In settings.py i added "allauth.socialaccount.providers.google", On the site i added a button google signin. When i use chrome as a browser everything works fine, the user is signed in over and over again. However with safari i have a problem. The first time when ik log in with the google sign in the user is logged in fine.

How to escape '/' in django urls
I am working on a project that generates dynamic urls for eg if you type mysite.com/<yourtexthere> The site should generate a url with mysite.com/yourtexthere (where yourtext here is a slug of a model)and I am able to do that but the problem arises when I put something like this mysite.com/yourtexthere/moretext, Django doesn't match it with any of my existing URL patterns and gives me 404. I wanted to ask is there a way by which I can treat '/' as just another character and generate unique url mymysite.com/yourtexthere/moretext where yourtexthere/moretext is now the slug. views.py def textview(request, slug): obj, created= Text.objects.get_or_create(slug=slug, defaults={'text':'', 'password':'123'}) return render(request, 'text/textpage.html', {'obj' : obj, 'created' : created}) urls.py # Only patterns urlpatterns = [ path('', home, name='home'), path('<slug:slug>/', textview, name='textview'), ] -
Django allauth - how to send users that just signed up with Google to an intermediate screen where they fill out additional informations
I integrated django-allauth with my Django app but I would like to make a small tweak on the current sign-up flow. Problem Currently if a user uses google sign-up to sign-up on my app, django-allauth creates an account for them extracting a certain amount of informations from google and then send the user to the home-page. Desired behavior I would like users who just finished the authentication process through google/allauth,to be sent to an intermediate screen (that they can skip if they really want) where they are asked additional informations (like phone number) so that I can complete their profile.

django get lazy reference by Model
To get model from lazy reference, we can do from django.apps import apps Article = apps.get_model('articles.Article') # app.Model But what about the reverse for it? I mean to get the lazy reference app.Model by Model class. from articles.models import Article # something like print(Article.lazy_reference) # <str> articles.Article you probably wonder why I do this, I need to tract user initiative and passive actions, there's no modelfield in django, hence I store the model reference and pk as indication.
