How to get a list of all the Product Attributes associated with the Products displayed on a Product Category Page?
On the Product Category pages a set of Products are displayed using a HTML template with context from the view.py. In the sidebar of the HTML page, I want to display all the Product Attributes associated with the available Products on the page (here's an example). In other words, I want to access the Product Attributes in the template file of the Product Categories. The Product Attributes have the Product Categories as foreign keys, as seen in the code below. # views.py # class ProductCategoryListView(ListView): template_name = "products/product_categories.html" # Default fetch template location: <blog>/<modelname>_list.html #queryset = Product.objects.filter(categories_id = ) # e.g. id=1 def get_queryset(self): self.category = get_object_or_404(ProductCategory, slug=self.kwargs["slug"]) #id=self.kwargs["id"] return Product.objects.filter(categories=self.category) # categories_id=self.category.id #return Product.objects.filter(categories__contains = self.category.get_descendants(include_self=True)) def get_context_data(self, **kwargs): # Call the base implementation first to get a context context = super().get_context_data(**kwargs) # Context of Product Category context['full_name'] = self.category.full_name context['ancestors'] = self.category.get_ancestors context['category'] = self.category context['descendant_count'] = self.category.get_descendant_count context['descendants'] = self.category.get_descendants(include_self=False) context['siblings'] = self.category.get_siblings(include_self=False) context['filter'] = ProductFilter(self.request.GET, queryset=self.get_queryset()) attributes = [] for product in Product.objects.filter(categories=self.category): attributes.append(...) context['attributes'] = attributes # Get attributes of the category return context # models.py # class ProductAttributes(models.Model): """ The Product Attributes Table contains product attributes or features for the product category.

REST api for system admin
i am trying to understand what is special in REST api. I am from a infra admin background and for me a HTTP server handling GET, PUT and POST looks like a REST end point. is this magic lies in the word "framework". which define some standards for communication over HTTP. other than that it just like a webserver. example: GET /users is REST GET /users?id=user1 is not REST why the 2nd one is not REST? django vs django rest framework DRF? if i read a django code -- in urls.py urlpatterns = [ path('/users', views.get_user), ] -- in views.py def users(request): if request.method == "GET": return JsonResponse({'users':'all_users'}) if request.method == "POST": ## add user return JsonResponse({'success':'OK'}) is this /users endpoint is not REST? what will be the difference with DRF can anyone please explain this in a layman term people other than development background can understand? -

How to generate a choices tuple for django models field to use in a form
Trying to create a choice field based on another model I want my choices to be mapped like username: first_name + last_name I tried doing something like this(Note, I am adding on user_choices and choices=user_choices. The model already existed before me making these changes.) Here's what my models.py looks like: from django.contrib.auth.models import User owner_choices = [ tuple(User.objects.values_list('username', 'first_name' + 'last_name')) ] class ErrorEvent(models.Model): """Error Event Submissions""" event_id = models.BigAutoField(primary_key=True) owner = models.IntegerField(verbose_name="Owner", blank=True, choices=owner_choices) and here's my forms.py from django import forms from .models import ErrorEvent class ErrorEventForm(forms.ModelForm): class Meta: model = ErrorEvent # fields = exclude = ['event_id'] widgets = { 'owner': forms.Select(), } Currently the owner_choices doesn't work, I get an error that says: ERRORS: app.ErrorEvent.owner: (fields.E005) 'choices' must be an iterable containing (actual value, human readable name) tuples. Any recommendations on what else I can try, or how would I go about fixing my problem? Thank you in advance! -
How to store the default value for a Django form in the database?
I have a page with bookmarks and I want to implement several types of sorting for them. The user chooses the type of sorting and it's stored in the database. He/she sees the chosen type of sorting as the default value for the select-menu. I wrote this: class BookmarksSortingForm(forms.Form): SORTING_CHOICES = [(1, "новым"), (2, "имени"), (3, "звёздам -"), (4, "звёздам +")] bm_sorting = forms.ChoiceField(SORTING_CHOICES) # https://stackoverflow.com/questions/6325681/passing-a-user-request-to-forms # In your view: form = MyForm(..., request=request) def __init__(self, *args, **kwargs): self.request = kwargs.pop("request", None) super().__init__(*args, **kwargs) self.fields['bm_sorting'].initial = BookmarksSortingForm.SORTING_CHOICES[self.get_current_sorting() - 1][1] def get_current_sorting(self): user = User.objects.get(username=self.request.user) return user.profile.bookmarks_sorting # small integer, default = 1 But I get "TypeError: init() takes 1 positional argument but 2 were given" at the line with bm_sorting. How could I fix this? Django version is 3.2.4. -

Django app engine can not connect to db No such file or directory Is the server running locally and accepting connections on Unix domain socket
I have a Django app that I built, I am trying to upload the app into the app engine, but for some reason, I am getting the error could not connect to server: No such file or directory. Is the server running locally and accepting connections on Unix domain socket I already upload another Django app to GCP using the app engine, but this time is different; my guess is something about PostgreSQL. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'main', 'USER': os.getenv('USERNAME'), 'PASSWORD': os.getenv('PASSWORD'), 'HOST': os.getenv("HOST"), 'PORT': '5432' } } I tried removing the port, change it, etc.. locally. The app is running and can connect to the proxy; when I deploy the app, it can not connect. And I made sure I close the local connection before I deploy the app just in case. My old app is running with the same configuration except for engine 'django.db.backends.postgresql_psycopg2' The reason I change the engine here was that django postgresql -

How to check for `--keepdb` flag in Django
I've created an AppConfig that uses the post_migrate signal to run some extra SQL every time I do a migration. In my tests sometimes I use --keepdb to speed up running the tests but it's still triggering the post_migrate signal. How can I check to see if the --keepdb flag was used so I can skip running my extra SQL commands? I've looked in the Django documentation and the source code and I can't seem to find any way to do that. -

I am trying to update a profile and I am using Class based views views.py: class ProfileUpdateView(UpdateView): model = User template_name = "users/profile_update.html" success_message = "Your profile was updated successfully" slug_url_kwarg = 'username' slug_field = 'username' context_object_name = 'profile' fields = ['username', 'email'] def get_success_url(self): return reverse_lazy("profile", kwargs={self.slug_url_kwarg:self.kwargs['username']}) If I don't update anything and click on the update button, it redirects me to my profile page.. But if I update, it does not redirect me but rather, it stays is the same page.

use rest_framework_simplejwt with Django 1.11.x and Python 3.6.2
I have an app that is using Django 1.9.2 and python 2.7. Now I wanted to use the simple JWT solution on a REST API and started to upgrade the app to Django 1.11.29 and Python 3.6.2. I cannot upgrade to Django 2.x at a reasonable cost ;-) When I use the url for access token, I am getting correctly my pair of access token and a refresh token back. But when I use refresh token url -X POST \ -H "Content-Type: application/json" \ -d '{"refresh":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX3BrIjoxLCJ0b2tlbl90eXBlIjoicmVmcmVzaCIsImNvbGRfc3R1ZmYiOiLimIMiLCJleHAiOjIzNDU2NywianRpIjoiZGUxMmY0ZTY3MDY4NDI3ODg5ZjE1YWMyNzcwZGEwNTEifQ.aEoAYkSJjoWH1boshQAaTkf8G3yn0kapko6HFRt7Rh4"}' \ http://localhost:8000/api/token/refresh/ I should get back my access token like "access": "eyJ0eXAiOiJ.........." } But I get a response like { "username": [ "this field is required" ], "password": [ "this field is required" ] } I mocked up another super-limited Django app running under Django 2.2.2 and things behave like required. Can anyone help me on this?
