How can I group products based on their age in django?
I have a django ecommerce site where I have products for 3 age groups. i.e. Child, Adult, Senior. The issue is one product can be on more than one age group. How can I arrange that with the product model? I tried using booleans and use select option but when I change pages it gives "keywords must be strings" error because of the filter. Here is my code: Templates <li class="age"><Form action="{% url 'get_products' %}" method="get"> <select style="text-transform: uppercase;" name="age_group" onchange="submit()"> <option value="" selected disabled>Gifts by Age</option> <option value="infant">Infant</option> <option value="toddler">Toddler</option> <option value="child">Child</option> <option value="teen">Teenager</option> <option value="adult">Adult</option> </select> </Form></li> Views def get_products(request): # getting the age group you passed via form age_group = request.GET.get("age_group") products = Product.objects.filter(**{age_group: True}) paginator = Paginator(products, 1) page_number = request.GET.get('page') products = paginator.get_page(page_number) context = {'products': products } return render(request, "age.html", context) -

Why my custom script processing data just fine on local development Django server but not on Digital Ocean App?
Does anyone know why when I upload a CSV file locally to the Django development server, my code does work as plan as in processing the CSV file and adding data to the database correctly, but when I try the same thing with the production server on Digital Ocean using App service - the CSV file just uploaded without having getting processed? I notice this because no new product is being added when uploading the CSV file to the production server on Digital Ocean. By the way, the local development server is also using S3 storage - so the same file got uploaded to Amazon S3 all the same - but the code processes the file in the development server but not on the production server - the development server is on my laptop. The production server is on Digital Ocean's App. I did something like this in the code: from django.core.files.storage import default_storage def upload_csvs(request): current_page_bread_crumb_title = 'upload csv' form = CsvsModelForm(request.POST or None, request.FILES or None) random_category = None if form.is_valid(): form.save() # reset form after save form = CsvsModelForm() # Only getting csv file that isn't activated or being used already. get_csv_data = Csvs.objects.filter(activated=False).order_by('-id').first() with default_storage.open(get_csv_data.file_name.name, mode='r') … -
How to query a dropdown in a Django ModelForm field based on current logged in user

Get data belongs to a field of model in select_related to a list and create a dataframe
I'm trying to query two related tables and create a pandas dataframe then use it for rule mining. The dataframe should look like this, order products ---------------- 1 ['product1', 'product2'] 2 ['product1', 'product3', 'product10'] ... My models, class Order(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) product = models.ManyToManyField(Product, through='OrderedProduct', related_name='orders') class OrderedProduct(models.Model): order = models.ForeignKey(Order, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.DO_NOTHING) quantity = models.IntegerField(default=1) class Product(models.Model): name = models.CharField(max_length=255) price = models.DecimalField(max_digits=10, decimal_places=2) I've done the dataframe creating part as follows in views, and it works but needs preprocessing to get end result and feels it's inefficient for a larger dataset. orders = OrderedProduct.objects.all().values('order__id', 'product__name') df = pd.DataFrame.from_records(orders) df = df.groupby(['order__id'])['product__name'].apply(list).to_list() So, my question is 'Is there a more direct and efficient approach to do this?'. Any advice is highly appreciated. -

Django - object has no attribute 'object' when injecting POST form data
Goal I'm trying to inject the "Send BCC" Job Site email addresses/objects into the form as the initial default value. The difficulty seems to be how it's interpreting super().get_context_data(**kwargs) and the view somehow is missing the object() it's looking for.
