Django application structure,
I'm trying to deploy my Django project to Google AppEngine, however I can't figure out how to properly set up application entrypoint. This is my whole project structure: service-master: app.yaml main.py service: manage.py service-project: wsgi.py settings.py ... service-app-1: ... service-app-2: ... How can I make it work? I tried to move main.py to service and use entrypoint: gunicorn --chdir /service main:application in app.yaml but it results in Error: can't chdir to '/service', I guess AppEngine doesn't allow to change directory. -
Displaying title in the django administration instead of object
I have got a main table called Item and table Bike that is connected to Item with OneToOneField. When I add a new Bike using django administration page, it shows as Bike object (1). Is there a way to show the title of that Bike, that is stored in the Item table instead of that "Bike object (1)"? my models.py: class Item(models.Model): title = models.CharField(max_length=100) price = models.FloatField() discount_price = models.FloatField(blank=True, null=True) label = models.ManyToManyField(Label, blank=True) slug = models.SlugField(unique=True) description = models.TextField() class Bike(models.Model): item = models.OneToOneField(Item, on_delete=models.CASCADE) category = models.ManyToManyField(Category, blank=True) image = models.ImageField(upload_to='bikes') -
Windows IOError: [Errno 13] Permission denied:
I'm setting up tinymce with Django for the first time and we want to enable image upload. I configured the image upload URL, even managed to pass the CSRF token, otherwise Django wouldn't accept the POST request. Here's the view tinymce is interacting with: @login_required @require_http_methods(['GET', 'POST']) def upload_image(request): if request.method == 'GET': return JsonResponse({'location': settings.IMAGES_DIR}) if request.method == 'POST': with open(settings.IMAGES_DIR, 'wb+') as destination: for chunk in request.FILES['image'].chunks(): destination.write(chunk) I set up settings.IMAGES_DIR as in the local project directory just to test it out. However when the function gets to the part where it starts writing the file I'm getting the following error: IOError: [Errno 13] Permission denied: 'C:\\Users\\xxxxxx\\PycharmProjects\\xxxxx\\media' I am not too familiar with Windows permissions but I checked the folder properties and every user group seems to have write permissions. Now, I'm not sure "who" is the user doing the actual writing, it must be the user running the PyCharm server locally, right? Well, that's just my regular Windows user which is an admin and all, and in any case has write permissions in that folder as I mentioned. What's going on here? PS: yes, I am on Windows and I am using Django 1.8. Please don't … -
What can I do to make 'id' = id in this class-based view in Django?
views.py from django.shortcuts import render from django.views.generic import DetailView from .models import Producto def general_view(request): context = { 'articulos': Producto.objects.all(), } return render(request, 'shop/general_view.html', context) class DetailedView(DetailView): model = Producto template_name = 'shop/specific_view.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['determinado'] = Producto.objects.get(pk=*¿?*) return context urls.py from django.urls import path from . import views from .views import DetailedView urlpatterns = [ path('', views.general_view, name='general-view'), path('<int:pk>/', DetailedView.as_view(), name='specific-article'), ] As you see, the problem occurs because I don't know how to call the id or pk in the detailed_view in views.py, I'm guessing you maybe have to do a dictionary but I don't know where to do it nor how. It works if I set the id to 1, but obviously what this does is that is shows in every url with a different id the same article. -
Deploy django app as static pages on common static web-hosting provider? [closed]
I've worked a few times on django but I'm not an expert and I don't know all the low level functionalities of the framework. With that in mind, I was wondering if there's is a way to deploy a django app as a static website or if there's something out there that generates html pages out of a django project (connecting routes to files, fixing links, etc.) and then store those generated files on static web-hosting provider (i.e. github-pages) I've looked around but I couldn't find anything worth trying out. What do you guys suggest? -
how manage connections of mysql for concurrent request passes from celery
We are using 'django-db-connection-pool' package to manage connection pooling. We are trying to execute two tasks concurrently using celery with two different queues of rabbitmq(rabbitmq is celery broker), one task execute successfully but second task is not succeeded , this will drop mysql connections. if we try both functions without queuing, it will work properly. That means, if concurrent request is passed to mysql that loss mysql connections. for sequential execution it will works properly. Please provide solution to overcome this issue. Thanks in advance. -
Object not being saved to database Django
I have a webapp with a friends feature, which is all working except for the bit of saving the current user into the requested user's ManyToManyField. Here is my model friends = models.ManyToManyField(User,blank=True,related_name='user_connections') And my view class AddFriendRedirect(RedirectView): def get_redirect_url(self,*args,**kwargs): username = self.kwargs.get("username") obj = get_object_or_404(UserProfileInfo,slug=username) # print(f'OBJECT: {other}') # print(f'Current user: {self.request.user}') # user_profile = User.objects.get(username=username) url_ = obj.get_absolute_url() user = self.request.user user_ = self.request.user.username # user__ = print(f"HEY YOU!

On obj.friends.add(user), it adds the current user to their Manytomanyfield, but it's just not working on the user.user_connections.add(obj) one. I have tried heaps of things, including user.friends.add(obj) user.userprofileinfo.friends.add(obj) user.userprofileinfo.user_connections.add(obj) UserProfileInfo is my custom UserProfile model I am just confused as to why this isn't working, and it's weirder because no errors are being thrown either.

How can i delete a database row from a Django view? [duplicate]
I created a form where an user can delete some preferences from the Database. Here is my view: if 'button2' in request.POST: instance = Keys.objects.get(id=request.POST['id']) form2 = DeleteKey(request.POST, instance=instance) if form2.is_valid(): profile = form.save(commit=False) profile.key = '' profile.save() messages.success(request, f"Success") return HttpResponseRedirect(request.path_info) And the form: class DeleteKey(forms.ModelForm): class Meta: model = Keys fields = () def save(self, commit=True): send = super(DeleteKey, self).save(commit=False) if commit: send.save() return send This code works, the problem is that i'm not really deleting the row from my own database, i'm just setting that field to an empty string. Is there any way to completely delete the row, instead? Thanks in advance! -

How do I increase an IntegerField in Django?
I am making a Todo list web app in Django. I am just learning Django and a very much novice, so any help is greatly appreciated. My problem: My app will allow users to sign up and they can have a profile of their own. They can create ToDos and delete them as they want. Now, I want to introduce an attribute to all the users called "todos". This is basically an integer value that will keep track of how many todos they have created since they signed up. And every time the user adds a new task, I want this value to increase by 1. I just can't seem to figure out how to implement this. This is my models.py from django.db import models from django.contrib.auth.models import User from PIL import Image class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default="default.jpg", upload_to="profile_pics") todos = models.IntegerField(default=0) def __str__(self): return f"{self.user.username} Profile" def save(self): super().save() img = Image.open(self.image.path) if img.height > 300 or img.width > 300: output_size = (300, 300) img.thumbnail(output_size) img.save(self.image.path) views.py class TodoListView(ListView): model = ToDo template_name = "ToDo/home.html" context_object_name = "todos" ordering = ["-date_posted"] class TodoCreateView(CreateView): model = ToDo fields = ["title"] success_url = reverse_lazy("todo-home") def form_valid(self, form): … -

Django ORM Group by, Sum with row ID to get position of user on leaderboard
