Django foreign key constraint on drop even thou on_delete=CASCADE
I can't see what's wrong with this, class Agenda(models.Model): ... class AgendaResource(PolymorphicModel): agenda = models.ForeignKey( Agenda, related_name="resources", on_delete=models.CASCADE ) comment = models.TextField(null=True) class PreemptiveMeasureResource(AgendaResource): resource = models.ForeignKey( PreemptiveMeasure, on_delete=models.SET_NULL, null=True ) ... When I try to delete an agenda, i.e. Agenda.objects.get(pk=2).delete() I get this problem: update or delete on table "school_health_agendaresource" violates foreign key constraint "school_health_preemp_agendaresource_ptr_i_222e2e2c_fk_school_he" on table "school_health_preemptivemeasureresource" DETAIL: Key (id)=(2) is still referenced from table "school_health_preemptivemeasureresource" What is it I don't understand? I'm guessing it's something to do with the inheritance? -
How can I edit the content in the home page?
Working on a small project using Django 3.2 and I just added an edit button to the page, so the user can edit the content. I did that with forms and views by rendering the user to another page and edit the content, but I was thinking is there a way possible to edit the content by not rendering user to another page? For a better understanding of what I have done so far, will show the code below: models.py from django.db import models from django.contrib.auth.models import User from django.db.models.deletion import CASCADE # Create your models here. class todo(models.Model): content = models.CharField(max_length=200) created = models.DateTimeField(auto_now_add=True) name = models.CharField(max_length=200, null=True) email = models.CharField(max_length=200, null=True) user = models.ForeignKey(User, on_delete=CASCADE, null=True) def __str__(self): return self.content forms.py class UpdateContent(forms.ModelForm): class Meta: model = todo fields = ['content']' views.py contents = todo.objects.get(id=pk) form = UpdateContent(instance=contents) if request.method == 'POST': form = UpdateContent(request.POST, instance=contents) if form.is_valid(): form.save() return redirect('/') context = {'form': form} return render(request, 'html/update.html', context) home.html table class="table table-dark table-hover table-bordered"> <thead> <tr id="tr-table"> <th id="text-left">#</th> <th id="text-center">ITEMS</th> <th id="text-right"><i class="material-icons">&#xe872;</i></th> <th id="text-right2"><i id="edit" class="material-icons">&#xe3c9;</i></th> </tr> </thead> <tbody> {% for all_item in all_items%} <tr> <th id="row" scope="row"> {{ forloop.counter }} </th> <td id="content">{{ all_item.content … -
Change the Django Admin App List and Restrict Users from accessing models
I am trying to create a system in django admin model where admin can see all apps in django admin index. Staff can see only restricted apps. I was able to change the app list index for different roles, but for restricted user they can access directly through url. model.py class User(AbstractBaseUser): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) email = models.EmailField( verbose_name='email address', max_length=255, unique=True, ) first_name = models.CharField(('first name'), max_length=30, null=True) last_name = models.CharField(('last name'), max_length=30, null=True) date_of_birth = models.DateField(null=True) date_joined = models.DateTimeField(('date joined'), auto_now_add=True) # avatar = models.ImageField(upload_to='avatars/', null=True, blank=True) phone = PhoneNumberField(null=True) country = CountryField(null=True) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) staff = models.BooleanField(default=False) is_consumer = models.BooleanField(default=True) # premium_referral = models.CharField(('Premium Referral Code'), max_length=30, null=True,blank=True, unique=True) objects = UserManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] def __str__(self): return self.email def has_perm(self, perm, obj=None): "Does the user have a specific permission?" # Simplest possible answer: Yes, always return True def has_module_perms(self, app_label): "Does the user have permissions to view the app `app_label`?" # Simplest possible answer: Yes, always return True def get_full_name(self): ''' Returns the first_name plus the last_name, with a space in between.

How to handle high response time
There are two different services. One service -Django is getting the request from the front-end and then calling an API in the other service -Flask. But the response time of the Flask service is high and if the user navigates to another page that request will be canceled. Should it be a background task or a pub/sub pattern? If so, how to do it in the background and then tell the user here is your last result? -
HTTP Redirects Preventing Twilio From Sending Digits Parameter
I created a Django app which uses if/else statements in multiple views. The else statements contain response.redirect("/previous_view"). If the else statement is ran it generates 3XX HTTP codes and causes Twilio not to include the Digits parameter in the POST body which causes my "if" statements to fail. How do I fix this? Twilio is a well-behaved HTTP client, so when it receives an HTTP 301 or 302 redirect it will follow it to the specified URL. However, on the subsequent request the original parameters are not included. Occasionally you may see parameters such as Digits or RecordingUrl not arriving where you expect them. In this case, check to make sure the URL is not returning a redirect. As an example, when a request is made to the action URL, a Digits parameter is included in the POST request. If the action URL redirects to another URL, Twilio will follow the redirect and issue a GET request to the specified URL. This GET request will include the standard set of parameters included with every Twilio request, but will not include the additional Digits parameter. Common situations that may return unexpected redirects are: A server that automatically redirects all HTTP requests … -
Should I use AWS for my Redis Broker or Heroku (Django app using Celery)?
I'm a very beginner dev and I'm a bit confuse. Here's my situation: I have a Django web app running on a AWS EC2 server. I have a specific view function that renders results using Spotify API and some results take 30 seconds to be rendered. I've heard that Celery could help me create a loading bar system to let the clients know how the loading is going. I have to use a message broker and Redis seems to be a good one. All the tutorials I saw are using Heroku as a host, but I'm already using AWS. I didn't find any resources speaking about AWS + Redis in the case where Redis is used as a Broker with Celery in Django, but I know that Redis + AWS is something common for cache. Can I use AWS for this purpose? If yes, is it worth it compares to Heroku (which seems very simple)? Btw, cache seems to be a good solution for my long loading issue, so I might also use Redis for cache handling. -

Aggregation using relations and __last in Django
I need to find out how to filter the amount of new customers in a specific store, filtered by days. I tried a few aggregations, but none seemed to work. See code below # query all orders in a specific store by day (simplified) orders = Order.objects.filter(created_at_gte=today, created_at_lt=tomorrow, store=store) # filter all unique customers customers = [] for order in orders: if not order.customer in customers: customers.append(order.customer) # iterate all customers, looking for the oldest order for each one in that store and count as a new client if this oldest order is between the dates being looked up new_customers = 0 for customer in customers: oldest_order = customer.orders.filter(store=store).prefetch_related('store').last() is_new = (tomorrow > oldest_order.created_at > today) if is_new: new_customers += 1 print(new_customers) However, this code takes too long due to the iteration in: oldest_order = customer.orders.filter(store=store).prefetch_related('store').last() I believe something like the below would work, but "__last" doesn´t work here. Order.objects.filter(store=store, created_at__gte=today, created_at__lt=tomorrow).annotate(Count('customer__orders__last', distinct=True)) Thanks! -
How to display/see the default values in Admin for translated fields using Django's modeltranslation
I'm trying to translate some models in an existing project, and I'm learning how to do that using the modeltranslate extension.

Even in the model's table now there are no names displayed at all as can be seen here: Questions: How can I see the original value of these translated fields? How do I keep seeing Equipment names in the overall model's view (the second screenshot)? -
How to add status to google registered accounts?
I have a registration with 2 categories of users. Before filling in the fields, I have to choose which category I want. If you fill in the fields (email, username, password, etc.) it is saved in the database all the information (even the status). If I choose a certain category of user and I want to register with the account Google, the account is registered but nothing is added to the status. The button that directs me to register looks like this: <a class="btn btn-primary" name = "status" href="{% url 'registerClient' %}" role="button" value = "Client">Client</a> Google registration button: <a href="{% provider_login_url 'google' %}" class="btn float-right login_btn" name='status' value= "Client" type = 'submit'>Login With Google</a> I also tried such a button: <button class="btn float-right login_btn" name='status' type="submit" value='Client'><i class="fas fa-user-plus"></i> Client </button> I also tried after registering with my google account to choose the status again (pressing a button depending on my choice), but nothing is saved in the database. in column status. Note that I use allauth (I installed everything and set it up properly). The only problem is that the status is not saved in db (and I really want that). Any ideas on how I could save … -

How to get value from Django view into Ajax success function
I have a django application where a user can upload a file on form submit. When the file is uploaded the program will get the column names from the csv file and display that in the Django Template This is my views def handle_new_file(request): if (request.method == 'POST'): form = NewFileForm(request.POST, request.FILES) if form.is_valid(): csv_file = request.FILES['csv_file'] fs = FileSystemStorage() file_name = fs.save(csv_file.name, csv_file) file_url = f"./media/file_uploads/{file_name}" print(file_name) print(file_url) cols = get_column_names(file_url) form.save() return HttpResponse(cols) While the above view is called successfully on form submit, I am not able to pass this cols data back to the template.

How to patch (or mock) Django’s ImageField form field’s properties?
I have a model which includes an ImageField (lets call it my_project.models.Profile) and a corresponding form (my_project.forms.ProfileForm). Let us say the name of the model’s field is picture. I am writing tests for the form and need to test the handling of the content_type property of the form's ImageField file underlying object, by my own project. For the life of me, I cannot work out where I would patch this property, to test the different scenarios. What I figured out: django.forms.fields.ImageField has a method to_python which transforms the uploaded binary data into an actual image file (https://github.com/django/django/blob/aec71aaa5b029640ce066fe5dc34f7a0050d50b2/django/forms/fields.py#L621). It uses PIL.Image to do so. Once the image is successfully opened by Pillow, the file object to be returned by to_python is assigned the content_type property, taken out of the PIL.Image.MIME dictionary (https://github.com/django/django/blob/aec71aaa5b029640ce066fe5dc34f7a0050d50b2/django/forms/fields.py#L653). What would be the correct path for mock.patch? -

How to load bootstrap styles in Django
ingestion-dashboard/ ├── apps │ ├── adapter │ ├── authentication | |__init__.py │ ├── static │ │ ├── assets │ │ │-- css │ │ │── img │ │ │── scss │ │ │── vendor │ └── templates │ ├── accounts │ ├── home │ ├── dashboard │ ├── asgi.py │ ├── __init__.py │ ├── settings.py │ ├── staticfiles │ ├── urls.py │ └── wsgi.py ├── manage.py ├── requirements.txt └───staticfiles ├── assets │── css │── img │── scss │── vendor settings.py CORE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) # ingestion-dashboard STATIC_ROOT = os.path.join(CORE_DIR, 'staticfiles') STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(CORE_DIR, 'apps/static'), ) With this layout, django works fine with local server with proper loading of bootstraps and styles. But when i ran this on kubernetes/nginx , the app is working fine but missing bootstraps, styles. The staticfiles dir in ingestion-dashboard/dashboard/staticfiles is being populated by command django-admin manage.py collectstatic. Any help is appreciated. I have loaded styles as <script src="/static/assets/vendor/@popperjs/core/dist/umd/popper.min.js"></script> works fine with local development.
