Wagtail Images Suddenly Not Rendering on Front End
I have just encountered an odd problem I'm trying to debug but cannot figure out what is wrong. I have a wagtail site with images that were all working. At one point I refreshed the browser, and the images suddenly all disappeared from every page. wagtailimages_tags is there static is all loaded the images are all in the correct media directory as specified and have been uploaded through the CMS if i inspect element, the image is in fact coming through in the code perfectly. But the site itself just does not show the image. I have checked the CSS and nothing has changed there and it is not hiding the image somehow. My last resort - I actually started the project over completely in a new environment and added each application one by one to see if I could solve the issue ... nope. No images on the new install from scratch either! No idea why all the images would suddenly just fail to appear in browser. Just seems super strange to me. Any ideas on debugging appreciated. -
Creating new Objects instead of updating - Django
I am trying to use Update in Django, but it is not being updated, rather a new object of the model is being created in the database. For example, if I try to change product label "Laptop" to "Smartphone", Django creates a new product called "Smartphone" instead of updating "Laptop". This is my code Model: class Products(models.Model): label = models.CharField(max_length=50) description = models.CharField(max_length=250) first_price = models.FloatField(null=True) price = models.FloatField() quantity = models.IntegerField(default=0) image = models.ImageField(null=True, blank=True) def __str__(self): return self.label @property def imageURL(self): try: url = self.image.url except: url = '' return url Form: class ProductForm(ModelForm): class Meta: model = Products fields = ['label', 'description', 'first_price', 'price', 'quantity', 'image'] View: @login_required(login_url='login') def editProduct(request, id): product = Products.objects.get(id=id) form = ProductForm(instance=product) if request.method == 'POST': form = ProductForm(request.POST, request.FILES) if form.is_valid(): form.save() messages.success(request, 'Product was edited.') return redirect('index') context = { 'form': form } return render(request, 'store/edit-product.html', context) Template: <h3>Edit Product</h3> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} {{ form.label.label }} {{ form.label }} {{ form.description.label }} {{ form.description }} {{ form.first_price.label }} {{ form.first_price }} {{ form.price.label }} {{ form.price }} {{ form.quantity.label }} {{ form.quantity }} {{ form.image.label }} {{ form.image }} <input type="submit" name="Add product"> {{form.errors}} </form> Thank you … -
Django admin set fk_name = to_field in inline class only allows one image to be uploaded
I am new to Django and I ran into a problem when I tried enable the admin to add multiple images to a user profile at once. I created a Model Profile that allows a user to have one profile, and can have more than one photo in the profile. I want to use user_id to link images to profile and use user_id for filter. However, when I tried to upload more than one photo to a profile, it displays error. models.py class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, ) GENDER_CHOICES = ( ('F', 'Female'), ('M', 'Male') ) date_of_birth = models.DateField(blank=True, null=True) gender = models.CharField(max_length=1, default='F', blank=False, choices=GENDER_CHOICES ) about_me = SizedTextField( size_class=2, null=True, blank=True ) date_created = models.DateTimeField(default=timezone.now) class Photos(models.Model): user = models.ForeignKey( Profile, to_field='user', null=True, blank=True, on_delete=models.SET_NULL ) photo = models.ImageField( upload_to='photos/%Y/%m/%d/', blank=True ) admin.py class PhotosInline(admin.TabularInline): model = Photos fk_name = 'user'#only one photo allowed to be uploaded, I want more than one @admin.register(Profile) class ProfileAdmin(admin.ModelAdmin): list_display = ['user', 'date_of_birth','gender', 'about_me'] inlines = [PhotosInline,] Why does it only allow one photo to be uploaded? What must I do? -
I keep getting a 'There is no current event loop in thread 'Stream''
I'm trying to redo a project based on a github repo I found a while back. When I try to run the author's code I get the 'There is no current event loop in thread 'Stream''.

Select2 in django doesn't show the options
I want to join selections in a form. I have the model "Country" and the model "City". when a user selects a Country only the Cities listed in that country should be listed. The problem is that When I try to do it, in the form I cant see any options, so no country or cities are listed at all. This is my code: forms.py: Blockquote from django import forms from django.forms import ModelForm from .models import Country, City from django_select2.forms import ModelSelect2Widget class AddressForm(forms.Form): country = forms.ModelChoiceField( queryset=Comunidad.objects.all(), label=u"Country", widget=ModelSelect2Widget( dependent_fields={'city': 'city'}, search_fields=['name__icontains'], ) ) city = forms.ModelChoiceField( queryset=City.objects.all(), label=u"City", widget=ModelSelect2Widget( search_fields=['name__icontains'], max_results=500, ) ) '''''' This is what I have in models.py: class Country (models.Model): name= models.CharField(max_length=20, help_text="Añada Comunidad Autónoma") def __str__(self): return self.name class City(models.Model): name= models.CharField(max_length=20, help_text="Añada provincia") country = models.

So I see no Countries and no Cities at all, but database is not empty. I don't know what am I missing. Any help will be welcome. -

Pure CSS radial timer with Django
I know that it's possible to create timed animations in pure CSS, and I've been able to get a 5 minute radial timer working in CSS the way I'd like. I'm just getting started with Django, and I'm curious whether I can make this functional for users. If someone visits my page, would Django be able to pull their visit time and pass it to the CSS animation, so that the animation is at the same point in the progression for all visitors? Is there any way to make the animation progression persistent upon page refresh as well? I'm very interested to know if there is any JavaScript-free solution to this, even if it is unwieldy. -
Django total price of OrderItems in Cart
How can i get "total" price of items of OrderItem in cart model from these models down below? I tried doing something in views but I get attribute error that QuerySet' object has no attribute 'total'. views.py def cart(request): cart = Cart.objects.filter(order_user=request.user) order_items = OrderItem.objects.filter(cart__in=cart) total = 0 for i in order_items: total = i.quantity * i.item.price + cart.total cart.update(total=total) models.py class OrderItem(models.Model): cart = models.ForeignKey('Cart', on_delete=CASCADE, null=True) item = models.ForeignKey(Item, on_delete=CASCADE, null=True) quantity = models.IntegerField(default=1) class Item(Visits, models.Model): title = models.CharField(max_length=150) price = models.IntegerField(default=1000) image = models.ImageField(upload_to='pictures', default='static/images/man.png') description = models.TextField(default="Item") visits = models.IntegerField(default=0) class Cart(models.Model): order_user = models.OneToOneField(User, on_delete=CASCADE) ordered = models.BooleanField(default=False) total = models.IntegerField(default=0, help_text="100 = 1EUR") order_items = models.ManyToManyField(Item, related_name='carts', through=OrderItem ) -
What is the best way to create a 'list' associated with a model?
I want to be able to associate a company name in my models with a list of 'milestone' percentage points, in order to calculate how far each company is from the nearest milestone. For example: List_Of_Milestones = [5, 10, 15, 20, 25] Current_Progress = 9.5% Example Output = "Company A is 0.5% away from the 10% milestone, and 4.5% above the 5% milestone." The logic is simple from a Python standpoint, but I can't get my brain around how I would create this in a model setup and allow the user to set their own list of milestones.
