Wagtail Create Snippet from the frontend to accepts Images (Django)
I have a simple snippet using Django Wagtail. I would like to be able to update the logo from a "CreateView" but when it renders in my view it's expecting a foreign key. I would imagine it would be easy to create a from to do this but it's not. @register_snippet class MerchantSnippet(models.Model): name = models.CharField(max_length=255, blank=False, null=False, unique=True) logo = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, ) def __str__(self): return '{} {}'.format(self.user.first_name, self.user.last_name) panels =[ FieldPanel('name'), ImageChooserPanel('logo'), ] edit_handler = TabbedInterface([ ObjectList(panels, heading='Content'), ]) class ProductCreateView(CreateView): model = ProductSnippet fields = ['name','logo'] class ProductUpdateView(UpdateView): model = ProductSnippet fields = ['name','logo'] When I use the default example in the template I ended up just getting a drop down. {% render_field field class+="form-control" %} How would I be able to see an image preview in the event I am updating the snippet and the ability to upload a different one . In the event I am creating a new item the ability to select an upload an image. -

Using User Model in POST Django Rest Framework

How to make calculation of fields from different Models?
There are now three tables: class Product(models.Model): sku = models.CharField(max_length=200, unique=True) name = models.CharField(max_length=200, null=True) class HistoricalData(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) date = models.DateTimeField() demand_sold = models.IntegerField(default=0) class ForecastData(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) date = models.DateTimeField() demand_sold = models.IntegerField(default=0) I need to compare Historical and Forecast data for the list of products and calculate the accuracy rate. Formula like: ForecastData.demand_sold * 100/HistoricalData.demand_sold The current solution is to iterate through the history and forecast datasets and make calculations for demand_sold products = Product.objects.filter(...) queryset_hist = HistoricalData.objects.filter(product__in=products) queryset_forecast = ForecastData.objects.filter(product__in=products) I am wondering is there any elegant solution to calculate field from different Django Models. -

Tests for view names failing since upgrading to Django 4.0
In a Django project I have tests that check that a URL uses a specific class-based view. e.g. I have this view: from django.views.generic import TemplateView class HomeView(TemplateView): template_name = "home.html" And this test: from django.test import TestCase from django.urls import resolve from myapp import views class UrlsTestCase(TestCase): def test_home_view(self): self.assertEqual(resolve("/").func.__name__, views.HomeView.__name__) This test passes in Django 3.x but once I try it with Django 4.0 the test fails with: self.assertEqual(resolve("/").func.__name__, views.HomeView.__name__) AssertionError: 'view' != 'HomeView' - view + HomeView Obviously something has changed in Django 4.0 but I can't see anything related in the release notes. So, what's changed and how can I make this test work again (or how can I test this in a better way)? -
Difference between post method and form_valid in generic base view
Can you explain me what is difference between two methods based on generic base view in Django: post and form_valid? I have both in my views, and both save my forms.

I hope you can shed some light on this question. class SellerUpdateView(LoginRequiredMixin, UpdateView): model = Seller template_name = "main/seller_update.html" fields = "__all__" success_url = reverse_lazy("seller-info") login_url = "/accounts/login/" def get_object(self, queryset=None): seller, created = Seller.objects.get_or_create(user=self.request.user) return seller def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["user_form"] = UserForm(instance=self.object.user) context["smslog_form"] = SMSLogForm(instance=self.object) return context def form_valid(self, form): self.object = form.save() user_form = UserForm(self.request.POST, instance=self.request.user) if user_form.is_valid(): user_form.save() return super().form_valid(form) class AdUpdateView(LoginRequiredMixin, UpdateView): model = Ad template_name = "main/update_ad.html" fields = ("name", "description", "category", "tag", "price") login_url = "/accounts/login/" def get_context_data(self): context = super().get_context_data() context["picture_form"] = ImageFormset(instance=self.object) context["seller"] = self.object.seller return context def post(self, request, *args, **kwargs): self.object = self.get_object() form = self.get_form() formset = ImageFormset(request.POST, request.FILES, instance=self.object) if form.is_valid(): form.save() if formset.is_valid(): formset.save() return HttpResponseRedirect(self.get_success_url()) else: return form.invalid() def get_success_url(self): return reverse_lazy("ad-detail", args=(self.object.id,)) -

Django Models Save models with Variable Value
My Problem is the following: I want to have a list of counter models. These models have a property named "counter". I could just add a new counter model, but i think this is very inefficient, because every time I'm referring to a counter model with a ForeignKey that isn't already existing, I would have to add a new one. Is there a way to save memory like saving a list of models in another model to save memory and database space? -
Why using Django and React requires so much extra packages?
I have been going through a tutorial (https://www.youtube.com/watch?v=GieYIzvdt2U) where you have to use Babel, Webpack, and Redux which are all complicated in their regards. Why we can not use "djangorestframework" as my API and get the information using that API from React using JS. What do I gain using all these packages or I can not simply use what I am suggesting? -

How to update replicated Docker service
I'm still learning Docker, and unfortunately, after hours of reading its docs and trying various approaches, I need to ask for help here. I have 3 Droplets on Digital Ocean - dev, staging and production. They host a Django application and a database. Both dev and staging have one container, which is simply a Python container, and one MySQL container. I update them by pulling changes from a Bitbucket repository, applying migrations using docker exec -ti CONTAINER /bin/bash and restarting the Python container. The production Droplet has a replicated service and the image pulled from the container registry on Digital Ocean. I pull changes from the repository on Bitbucket, but because I can't simply restart the container, the changes are not reflected on the website. I tried docker stack deploy -c docker-compose.yml SERVICE --with-registry-auth and docker service update --image IMAGE SERVICE, but no effect. Any help would be appreciated. Thanks -
Django-restQL Vs Graphene-django
I recently stumbled upon 2 different Django libraries for graphql API development: Django-restQL and Graphene-django. I know they are fundamentally different, but in the end, they are both necessary for the development more precise GraphQL API compared to rest. That said, I'd love to know the challenges, special quirks and tweaks both frameworks have, and which would be "best" for the job.
