Django channels create a separate task that sends message to group at intervals
Essentially I am trying to create a real time applications for teams with Django channels. What happens is that there is a physics simulator that runs on the server and then sends the game state to be displayed on the client machines. What I need is a function that runs every 1/20 seconds on the server and then sends an output to each socket in a group. What I am currently thinking of doing is using threading to spin up a task (only needs to run for 60s total) which runs the physics simulation and then waits for the remaining time until the next execution. But I can guess that there is a real way to do this with Django channels which I can't find in the documentation. -
Django: Open a form from admin action
I'm trying to change some things inside this logic, so for now I'm only able to send a push notification to one user at the time and I'm trying to make that I would be able to select multiple users. So I have created an admin action which let's me to select some users and now I'm struggling about creating a form which would fulfill the users that I selected. This is what I have now (Sending push notification to one user at the time). Select users that I want to send the push notification. This is my code: class CustomUserAdmin(UserAdmin): fieldsets = ( (None, {'fields': ('password',)}), (_('Personal info'), {'fields': ('email', 'phone', 'companies', 'active_company', 'avatar', 'completed_registration', 'language')}), (_('Permissions'), {'fields': ('is_active', 'is_staff', 'is_superuser', 'groups', 'user_permissions')}), (_('Important dates'), {'fields': ('last_login', 'date_joined', 'work_hours_until', 'work_hours_from')}), (_('Terms and conditions agreement'), {'fields': ('agreement_date', 'agreement_text')}), ) add_fieldsets = ( (None, { 'classes': ('wide',), 'fields': ('phone',), }), ) list_display = ['id', 'phone', 'email', 'is_active', 'is_staff', 'is_superuser', 'date_joined', 'last_login'] ordering = ('-id',) search_fields = ('email', 'phone') exclude = [] actions = ('send_push_notification', ) def send_push_notification(self, request, queryset): # Create some kind of form and logic..?? queryset.update(is_staff=False) # This is just to test -
Doesn't save form in django python foreignkey
There is a form with input text, which is not saved and throws a ValidationError, because there is no such value in the foreignkey model. The problem is that the check goes against pk, but the name. How to do it? (via select it is impossible, since this is entered and ajax gives him options). models class Orders(models.Model): service = models.ForeignKey('Service', null=True, blank=True, on_delete=models.PROTECT) class Service(models.Model): name = models.CharField(max_length=150, db_index=True, unique=True) def __str__(self): return self.name forms class SimpleOrderAddForm(forms.ModelForm): class Meta: model = Orders fields = ['service'] def clean_service(self): name = self.cleaned_data['service'] try: get_service = Service.objects.get(name=name) return get_service.pk except get_service.DoesNotExist: return name picture html form: UPD: a question in a different vein: how to change validation from pk to name field in input forms? UPD2: when entering the correct value into input, it outputs: Choose the correct option. Your option is not among the valid values. the error is that when entering, you must specify the pk field for the Service model and then the model is saved. And how to make the comparison by the name field take into account when writing the form? UPD3: already asked this question in a different vein here: here and here -

SSO with roles and permissions
We have projects that interacts with regular users (general app) and company users (companies app). Therefore, in our projects, generally, we have two types of Users: Regular - authenticates with phone_number as identifier. Regular users are any Users that can do common staff in our system. Staff - authenticates with email as identifier. Staff Users belong to some company and they have some roles. So, we built SSO app, that keeps all users, because there are apps that need about any user and having separate app that handles users in one place was for us better choice. However, there are troubles with our idea... The company app has its SUPERUSER that can create some company, company branch and director of that company and etc. We create company-apps superuser in our SSO app and give it COMPANY APP SUPERUSER role. SSO app does not hold the specific roles of company for users, we don't want it. That is the responsibility of company app. So, there is the problem when director of company wants to invite (create) employee, he/she requests company-app, which in the box calls SSO app endpoint to create user. Inside of SSO app we don't know who is requesting … -

How to overwrite data from a model that is linked to the main model through a o-t-m relationship?
I have three models that are related to each other, namely: models.py class Shop(models.Model): number = models.PositiveSmallIntegerField() name = models.CharField(db_index=True) city = models.ForeignKey(ShopCity, on_delete=models.CASCADE) class Product(models.Model): name = models.CharField(db_index=True) price = models.DecimalField(max_digits=10, decimal_places=2) class ProductQuantity(models.Model): product = models.ForeignKey(Product, on_delete=models.CASCADE) shop = models.ForeignKey(Shop, on_delete=models.CASCADE) quantity = models.PositiveSmallIntegerField(default=None) In the admin panel they are linked in this way: admin.py class ProductQuantityInline(admin.TabularInline): model = ProductQuantity extra = 0 @admin.register(Product) class ProductAdmin(ImportExportActionModelAdmin): fields = ['name', 'price'] list_display = ['name', 'price'] inlines = [ProductQuantityInline] There is a need to overwrite data with REST API serializers.py class QuantitySerializer(serializers.ModelSerializer): class Meta: model = ProductQuantity fields = ('shop', 'quantity') class ProductSerializer(serializers.ModelSerializer): productquantity = serializers.SerializerMethodField(read_only=False) class Meta: model = Product fields = ('name', 'price', 'productquantity') def get_productquantity(self, obj): return [QuantitySerializer(s).data for s in obj.productquantity_set.all()] And finally my handler for REST API: views.py @api_view(['GET', 'PATCH', 'PUT', 'DELETE']) def api_product_detail(request, pk): product = Product.objects.get(pk=pk) if request.method == 'GET': serializer = ProductSerializer(product) return Response(serializer.data) elif request.method == 'PUT' or request.method == 'PATCH': serializer = ProductSerializer(product, data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) elif request.method == 'DELETE': product.delete() return Response(status=status.HTTP_204_NO_CONTENT) As a result, data such as the name and price are overwritten, and the productquantity is not overwritten.

How is front end generated when creating web applications using python Django? [closed]
First off, bare with me if my question seems odd as i have no experience in developing web applications. I know Django is used for the backend and the logic of a web application i.e website. But how is the front end and HTML, CSS, JS and all those UI stuff created when working with Django? Does the programmer separately write the UI with those mark up languages or does the Django framework create web pages automatically? -
