When adding urlpatterns in Django, why is views.index called instead of views.index()?
I was wondering, in the url.py-files, why are parentheses not used when calling methods from the view.py-files? For example, why does the following code not have a parenthesis at the end of views.index? urlpatterns = [ url(r'^$', views.index, name='index'), ] -
django inline_formset - set queryset for a field based on another field
I have three models - Item, Invoice and InvoiceItem. Each Item may have one or more tax-groups (name,rate, etc) associated with them. class Item(models.Model): name=models.CharField(max_length=100, unique=True, db_index=True) tax_group=models.ManyToManyField(TaxGroup) class Invoice(models.Model): number=models.CharField("invoice number",max_length=20,unique=True,default=invoiceIncrement, ) date=models.DateField("invoice date") contact=models.ForeignKey(Contact, on_delete=models.CASCADE) total=models.DecimalField(decimal_places=2, max_digits=12) class InvoiceItem(models.Model): invoice=models.ForeignKey(Invoice, on_delete=models.CASCADE, related_name='invoice_items') item=models.ForeignKey(Item, on_delete=models.CASCADE) tax=models.ForeignKey(TaxGroup, on_delete=models.CASCADE) quantity=models.PositiveIntegerField() rate=models.DecimalField(decimal_places=2, max_digits=12) total=models.DecimalField(decimal_places=2, max_digits=12,null=True) I have made an inline_formset using the following form, as given below. class InvoiceItemForm(forms.ModelForm): class Meta: model=InvoiceItem exclude=() ItemInlineFormSet = inlineformset_factory(Invoice, InvoiceItem, form=InvoiceItemForm, extra=1, can_delete=False, validate_min=True, min_num=1) Now, I need to make sure that, corresponding to each selected Item in the formset, the field tax should contain only the taxes associated with them. For the client side, I have added some ajax code to populate the tax fields based on selection of each item field. How do I make sure that the selected tax field is one among the ManyToMany value of the Item object? I have tried specified a custom formset to set a queryset to the field, like class BaseItemFormSet(forms.BaseInlineFormSet): def __init__(self, *args, **kwargs): super(BaseItemFormSet, self).__init__(*args, **kwargs) for form in self.forms: form.fields['tax'].queryset = Item.objects.get(form.fields['item']).tax_group.all() This doesn't work (and I'm not sure whether this is the right way to proceed).

Data table in Django template - Check data with multiple table
I'm building a subscription function using Django. Type A users create a lot of "program", Type B users can join this program.

Django: Filter for Product Colour
I am trying to create a filter for product colours. Products are imported by csv and each colour drastically varies e.g camo, lilac, auburn. I want to create a filter with a selection of standard colours e.g red, blue green. When one of the standard colours is selected, I would like to query the database and return all products that contain that colour (or that are in that colour category). For instance if the colour blue was selected, the filter would return queryset of any products that contained the colours: blue, teal, turquoise, cyan, denim. I have tried to do this with django filter (choices) but have been unable to come up with a solution. Does anyone know the best approach for this? current product model class Product(models.Model): aw_deep_link = models.CharField(max_length=500, default='') product_name = models.CharField(max_length=500, default='') aw_image_url = models.CharField(max_length=500, default='') search_price = models.DecimalField(max_digits=6, decimal_places=2, null=True) merchant_name = models.CharField(max_length=500, default='') display_price = models.CharField(max_length=500, default='') brand_name = models.ForeignKey('Brand', on_delete=models.CASCADE) size = models.ForeignKey('Size', on_delete=models.CASCADE) colour = models.CharField(max_length=500, choices=COLOURS, default='') rrp_price = models.DecimalField(max_digits=6, decimal_places=2, null=True) category = TreeForeignKey('Category',null=True,blank=True, on_delete=models.CASCADE) description = models.CharField(max_length=500, default='') def __str__(self): return self.product_name current filters import django_filters from .models import Product, Brand, Category from django.forms import CheckboxSelectMultiple class ProductFilter(django_filters.FilterSet): search_price__gt … -

Choices in Django model not being translated, possibly due to use of modelform or modelformset?
I am working on a Django project that connects dogs with behavioral issues with people who can help the owner overcome those issues. Most of the project has been translated, but there are a few strings that aren't being translated.

I'm working with the wagtailmedia extension to Wagtail within Django, and am unable to find media that I've uploaded to media directories that I'd expect to be accessible. For reference, the wagtailmedia repository can be found here. There are some questions up here about how to configure media for S3, but right now I'm just trying to get things running locally. I followed the configuration steps in the second example of the wagtailmedia README, but am confused about where wagtailmedia searches. Specifically, I have a wagtailmedia.Media field on one of my models: background_video = models.ForeignKey('wagtailmedia.Media', ... And a content_panel to modify it: content_panels = Page.content_panels + [ MediaChooserPanel('background_video'), ] And I have the following line to (in theory), serve media urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) in my Django settings for when in debug mode, and the value of settings.MEDIA_ROOT is media/. Does this mean that lookups occur at any directory in static called media, any directory called media, or something else? After setting this up, I created a MediaChooserPanel field for one of my models, and see this: (the no match part) when querying for files that I thought were located along the right paths. What can I do to fix … -

Django Rest Framework doesn't render generics.ListAPIView, model with GM2MField
First, sorry for my english, but it's not my native language. I have the next problem: I'm working in a Django app, I have a model like this: class AlarmEvent(models.Model): # Alarm types USER = 'US' DEVICE = 'DV' NO_DEVICE = 'ND' ALARM_CHOICES = ( (USER, 'User'), (DEVICE, 'Device'), (NO_DEVICE, 'No-Device') ) alarm = models.ForeignKey(Alarm, on_delete=models.CASCADE, null=True) alarm_type = models.CharField(max_length=2, choices=ALARM_CHOICES, default=USER) created = models.DateTimeField(auto_now_add=True) finished = models.DateTimeField(null=True) content_type = GM2MField() description = models.CharField(max_length=255, default='description', null=True) def __str__(self): return self.alarm_type + '-' + str(self.pk) As you can see, I'm using GM2MField() from third-party app: django-gm2m to have generic M2M relations. For this model I have the following serializer: class AlarmEventSerializer(serializers.ModelSerializer): class Meta: model = AlarmEvent fields = ('id', 'alarm', 'alarm_type', 'created', 'finished', 'device', 'variables', 'content_type', 'description') My problem is the next error: Environment: Request Method: GET Request URL: http://127.0.0.1:8000/api/alarms/events/ Django Version: 2.0.3 Python Version: 3.6.3 Installed Applications: ['alarms', 'fotuto_models', 'rest_framework', 'django_filters', 'guardian', 'corsheaders', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'gm2m', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles'] Installed Middleware: ['corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware'] Template error: In template /usr/local/lib/python3.6/dist-packages/rest_framework/templates/rest_framework/horizontal/select_multiple.html, error at line 15 'NoneType' object has no attribute '_meta' 5 : 6 : 7 : {% if field.label %} 8 : 9 : …
