Dockerfile not being found for Google cloud run
I've hit another bug. I'm now trying to set up continuous deployment for Google Cloud Run from my GitHub, and it's not finding my Dockerfile. I've tried various combinations with my file paths, but it still gives me the Already have image (with digest): gcr.io/cloud-builders/docker unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /workspace/Dockerfile: no such file or directory error. This is my file structure from VSCode, and if I run the command from the first Exeplore folder, it finds the Dockerfile The source directory is public, so I just can't figure out why it's not finding the Dockerfile. https://github.com/Pierre-siddall/exeplore Any advice at all would be greatly appreciated, thank you! -
django eventstream / channels return HTML
I have a working application where I use django-eventstream to show info/error messages to users. All works well with send_event(): send_event("ok_message", "message_ok", msg) send_event("error_message", "message_error", msg) but what I actually want to do is send some html directly to the frontend. Is this possible? send_event("ok_message", "message_ok", {"html": "<h1>test</h1>"}) -
How to add item to cart after the user login ? #django
I'm completely new to Django and I tried to create a simple eCommerce web application. In my code, when the user is not logged, items are easily added to the cart and displayed to the web application but when the same user logged into the application and tries to add the item to the cart it is not displayed in the frontend but the item is added to user from backend. I tried the logic if user.is_authenticated but I was not able to succeed. from carts.models import Cart, CartItem def add_cart(request, product_id): product = Product.objects.get(id=product_id) try: cart = Cart.objects.get(cart_id=_cart_id(request)) except Cart.DoesNotExist: cart = Cart.objects.create( cart_id = _cart_id(request) ) cart.save() try: cart_item = CartItem.objects.get(product=product, cart=cart) cart_item.quantity += 1 cart_item.save() except CartItem.DoesNotExist: cart_item = CartItem.objects.create( product = product, quantity = 1, cart = cart, ) cart_item.save() return redirect('cart') This is Django code adding items to the cart before the user login. -

Why Django doesn't update an object?
I have a model Profile, which connects with User. For example I have Testuser. When I try to update his field 'money', nothing happens. I suppose it may be because I use User, instead of Profile in get_object. But if I change it to Profile, there is an error, that Profile doesn't have username field. How can I solve this problem? model: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) money = models.IntegerField(default=0) form: class AddMoneyForm(forms.ModelForm): class Meta: model = Profile fields = ('money',) view: class AddMoneyView(UpdateView): model = Profile template_name = 'users/money.html' fields = ['money'] def get_object(self, queryset=None): return get_object_or_404(User, username=self.kwargs.get('username'), pk=self.request.user.pk) def get_success_url(self): return reverse('account', kwargs={'username': self.request.user.username}) url: path('account/<str:username>/money/', AddMoneyView.as_view(), name='money'), -

JWT with Django Rest Framework not working in production
My application uses Django Rest Framework for the APIs and JWT for authenticating the users. Everything was working fine in my local machine. I started having problems after a deployed it to an EC2 instance. The only things that still work are the login, registration and tokens refresh. That is, when I try to log in, I receive the tokens back from the back-end, which are successfully stored in the local storage; when I try to sign up, the back-end creates the new user; and from time to time the tokens are also successfully updated. But all the other API calls fail. At the beginning, when I made an API call, I was getting back "401 Unauthorized". I believe the reason was because Apache wasn't forwarding the Authorization-Headers. So I added "WSGIPassAuthorization On" to the Apache configuration. Now I am getting "500 Internal Server Error" instead. As I already said, only API calls to login, tokens refresh and registration are working. For login and tokens refresh, I am using the default "TokenObtainPairView" and "TokenRefreshView". from rest_framework_simplejwt.views import TokenObtainPairView, TokenRefreshView urlpatterns = [ path('log-in/', TokenObtainPairView.as_view(), name='token_obtain_pair'), path('refresh-token/', TokenRefreshView.as_view(), name='token_refresh'), ] For the registration, this is the view I am using: class … -

Python/Django - Input radiobutton to autosend email
I'm trying to set up a radiobutton input that let's you choose to send email automatically. What I want is a form that gives input: manual or auto. This will the one row I have in the sqlite3 database for this: class AutoSendMail(models.Model): auto = models.BooleanField(default=False) manual = models.BooleanField(default=True) send_type = ( ('manual', 'MANUAL'), ('auto', 'AUTO') ) type = models.CharField(max_length=6, choices=send_type, default="manual") So eventually what I want is that in AutoSendMail the type is set to manual or auto, depending on the radiobutton input.

Django: base.html "TemplateDoesNotExist at / error" and project structure
When in my home.html (or any other .html) I try to extend my base.html file with this {% extends "static/src/base.html" %} I get this error: TemplateDoesNotExist at / error Also, I'm about to start my first "serious" project and so I'm trying to do things a little less amateurish starting with my project structure. This is what I've come so far following the clues I got from other site, but I'd like to have some opinion from people with more experience than me if this is a good way to start the project. In particular, I'm a little confused about where to put the base.html file. Is it ok to put it in the src folder or should I put it with the navbar.html/footer.html/etc page or navbar.html/footer.html/etc should go in the src folder instead? This is my project structure: website_name - core (where is the settings.py and where I put homepage, news page, contact and about us page...) - app name_1 (like members) - app name_2 - media -- img -- upload (user ulploaded excel file) --- excel_file.csv -- download (for user to download file) - static -- src --- base.html --- style.css -- dist --- style.css -- node_modules -- … -
Is Django or Flask better for implementing "tracker nodes" and "seeder nodes" for p2p content sharing application?
The image below shows an architecture for video sharing based on the p2p BitTorrent protocol. The video player access the "content tracker" for "video" info The content tracker responds with "content node" info. The video is served from the nearest one or two nodes How should I approach building this network? Should I create a BitTorrent client at content nodes and give them a private "content tracker" address? If I have to expand the three-node structure to 10, what should be the approach while building this kind of software. Which tech stack would be best? If you can share some resources, that would be helpful. I am a newbie; kindly be kind. :) -
Django "ImageField" form value is None
I'm trying to implement profile picture field for users. The following is the code for each file for the implementation I tried, forms.py, models.py, views.py, and urls.py. I use a IDE (vscode) to debug django, and I placed a breakpoint on the user.avatar = form.cleaned_data['avatar'] line in views.py below, to quickly check if cleaned_data['avatar'] is filled as user input, as I expect. However, even after I upload a file on the url, submit, the line shows None while expected a image object, and of course it doesn't save anything so no change to the database either. # # forms.py # accounts/forms.py # from accounts.models import UserProfile # .. class UserProfileForm(forms.ModelForm): avatar = forms.ImageField(label=_('Avatar')) class Meta: model = UserProfile fields = [ 'avatar', ] def __init__(self, *args, **kwargs): super(UserProfileForm, self).__init__(*args, **kwargs) self.fields['avatar'].required = False # # models.py # accounts/models.py # from django.contrib.auth.models import User from PIL import Image class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) avatar = models.ImageField(upload_to="images", blank=True, null=True) # note: I also did "python manage.py makemigrations accounts; python manage.py migrate accounts;" # # views.py # accounts/views.py # class UserProfileView(FormView): template_name = 'accounts/profile/change_picture.html' form_class = UserProfileForm def form_valid(self, form): user = self.request.user user.avatar = form.cleaned_data['avatar'] user.save() messages.success(self.request, _('Profile picture has been …
