In my template, I would like to show all the related product types and their fields to a specific product: ... {% for product in products %} {{ product.??? }} {% endfor %} Here is my view: class ProductsView(ListView): collection = None model = Product paginate_by = 6 template_name = 'shop/product/list.html' context_object_name = 'products' def get_queryset(self): products = Product.objects.filter(available=True) collection_name = self.kwargs['collection_name'] if 'collection_name' in self.kwargs else None if collection_name: collection = get_object_or_404(Collection, name=collection_name) products = products.filter(collection=collection) return products def get_context_data(self): context = super().get_context_data(**self.kwargs) context['notification'] = Notification.objects.all() if 'collection_name' in self.kwargs: context['collection'] = get_object_or_404(Collection, name=self.kwargs['collection_name']) context['collection_name'] = self.kwargs['collection_name'] context['collections'] = Collection.objects.all() return context Thank you -
Django. How to correctly save time & timezones
I have this code that behaves in a rather strange way and opens the question, how should I deal with timezones? So, first I have a datetime object I build from the info a user posts: time_zone = request.POST.get("time_zone") date_start = request.POST.get("date_start") time_day = request.POST.get("time_day") time_zone_obj = pytz.timezone("Etc/" + time_zone) # GMT + 2 in this example date_start = datetime.strptime(date_start, "%d/%m/%Y") date_start = date_start.replace(tzinfo=time_zone_obj) time_day = datetime.strptime(time_day, "%I:%M %p") date_start = date_start.replace(hour=time_day.hour, minute=time_day.minute) ... event.date_start = date_start event.save() print("event.date_start.hour:%s" % event.date_start.hour) return redirect("event_detail", event_id=event.id) This prints event.date_start.hour:6. Then, inmediatlty after saving the object and printing the hour, it redirects to the event_detail view, very simple: def event_detail(request, event_id): event = get_object_or_404(Event, id=event_id) print("event.date_start.hour:%s" % event.date_start.hour) ... And it prints event.date_start.hour:8. I don't understand why. Plz note that I printed the hour after I saved the object and then after I retrieved it in the other view. It has a difference of two hours that must have something to do with the timezone the user selected (GMT + 2). Why is this? Which is the best way to save this data? The user submits "6:00 AM" + "GMT+2" in the form and then later when I want to show the time … -
django-rest-framework get the timestamp since the object created through serialization
I need to get the time since a post object was created. While surfing the internet I have found the following implementation and it gives me the following error Adding @property to models post object class Post(models.Model): timestamp = models.DateTimeField(auto_now=False, auto_now_add=True) @property def timesince(self): return timesince.timesince(self.timestamp) I do not know how the django.utils timesince works, if you know - give me a hint class PostSerializer(serializers.ModelSerializer): timesince = serializers.DateTimeField() class Meta: model = Post fields('__all__') I get the following AttributeError Got AttributeError when attempting to get a value for field `timesince` on serializer `PostSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `Post` instance. Original exception text was: 'NoneType' object has no attribute 'year'. -
Importing and creating pages in Django / Wagtail
Although Wagtail and Django seem to be very efficient and sophisticated frameworks, they do not offer any simple way of importing (i.e bulk creating) pages. I have tried dozens of suggestions to do so (eg 1, eg 2, eg 3, eg 4, etc). I've also tried CodeRedCMS (which is based on Wagtail), but it offers a very rudimentary function which have so far not helped me. Gazmans solution in this post seemed very efficient but I could not figure out exactly how to go about solving the issue. So my question is simple: If I have a csv/json file with thousands of rows, where each row represents a post for a specific Page Model I've created in Wagtail, how do I import it to Wagtail? Any example with psuedo code would be immensely appreciated. The only solution that I did (almost) succeed with was by using DataGrip and directly import data into the table, but then Wagtail did not register the entries for some reason. -
Django foreign key not getting data
I have two tables defined in my models: class Products(models.Model): productsid = models.AutoField(primary_key=True) product_number = models.CharField(db_index=True, max_length=15) title = models.CharField(max_length=255, default=None, null=True, blank=True) date = models.DateField(db_index=True, default=datetime.date.today, null=True, blank=True) class ProductFlag(models.Model): product_number = models.CharField(db_index=True, max_length=15) company = models.ForeignKey(Company, db_index=True, on_delete=models.SET_NULL, null=True) productid = models.ForeignKey(Products, db_column='productsid', db_index=True, on_delete=models.SET_NULL, null=True) I want to get the the 'title' from Products when I query ProductFlag. In my views, I make this query: productflags = ProductFlag.objects.filter(company__companyid=self.kwargs.get('company_id')).order_by('product_number') I thought that I could then reference the title field in my template by looping through {% for product in productflags %} and grabbing {{ product_number.productid.title }}, but I get nothing at all. Looking at it in the Django shell, it seems that my productid is always "None" (and my database definitely had data in productsid). I have no issue with the company foreign key. What am I doing wrong? Thanks-- Al -

How to set a list of default serializer instances?
I have some serializers class FruitSerializer(serializers.Serializer): id = serialiser.IntegerField() name = serializers.CharField() class BucketSerialiser(serializers.Serializer): id = serialiser.IntegerField(required=False, default = 1) fruits = FruitSerializer(required=False, many=True) And i want to set default values in the BucketSerialiser.fruits if initially they were not set. For example bucket = BucketSerialiser(data={'id': 1}) ... buket.data -> // it should return the default fruits data. e.g {'id': 1, 'fruits': [{'id': 1, 'name': 'Apple'}, {'id': 2, 'name':'Orange'}]. I tried to do it like this class BucketSerialiser(serializers.Serializer): id = serialiser.IntegerField(required=False, default = 1) fruits = FruitSerializer(required=False, many=True, default = [ FruitSerializer(data={'id': 1, 'name': 'Apple'}), FruitSerializer(data={'id': 2, 'name': 'Orange'})] But it doesn't work.

assigning additional variables to form in Django
I have a simple application draft where I would like to have three functionalities : priority list for every production line with 3 part number assigned to it ( and number of pieces for each ) order where I can select production line when submitting new order via form I would like to check the priority list and assign the appropriate part number based on the quantity left in stock to the order form. Also I would like to subtract value of 1 from the number of pieces Now, I have the first two and I assume they are not perfect (maybe you can suggest some tweaks). But how can I add the third functionality ? views.py def priority(request): priority_form = PriorityForm() if request.method == 'POST': priority_form = PriorityForm(data=request.POST) if priority_form.is_valid(): priority_form.save() return redirect('priority') else: priority_form = PriorityForm() return render(request, 'dashboard/priority.html', {"form": priority_form}) def order(request): storage = PartNumber.objects.all() username = request.user.username if request.method == 'POST': order_form = OrderForm(username=username, data=request.POST) if order_form.is_valid(): order_form.save() return redirect('order') elif request.method == 'GET': order_form = OrderForm(username=username) return render(request, 'dashboard/order.html', {"form": order_form, "username": username}) forms.py class OrderForm(forms.ModelForm): class Meta: model = Order fields = ('end_user_id', 'production_line_id') def __init__(self, *args, **kwargs): username = kwargs.pop('username', None) super(OrderForm, self).__init__(*args, … -
Django approval model form: how to show both new and old values in admin panel?
I've a model and I want to let users suggest changes on its objects.

First of all, creating a separate model is the best approach? If yes, how to show both original and suggested values in the admin panel? If no, what approach would you suggest? -

Cannot assign "(<User: admin>,)": "Event.owner" must be a "User" instance
This is weird. I have this code: from django.contrib.auth import get_user event.owner = get_user(request), event.save() In the model, owner is a ForeignKey to the User model. At first, I tried assigning it directly to request.user (as I've done all the times). I am not sure why I get this error: Cannot assign "(<User: admin>,)": "Event.owner" must be a "User" instance.
