How to count the number of objects depending on the status?
I have the code which counts the number of elements of each type. Views.py from django.db.models import Count class HomeView(ListView): model = TypeCartridge template_name = 'home.html' def get_context_data(self, *args, **kwargs): context = super().get_context_data(*args, **kwargs) type_counts = TypeCartridge.objects.values('type').annotate(total=Count('type')) context['type_counts'] = type_counts return context home.html: <div> {% for cartridge in object_list %} <div> <p>Number {{ cartridge.num}}: {{ cartridge.type }}, status {{ cartridge.status }}</p> </div> {% endfor %} <h2>Type Counts</h2> <ul> {% for type_count in type_counts %} <li>{{ type_count.type }} - {{ type_count.total }}</li> {% endfor %} </ul> </div> For example, I have a table: num type Status 0000001 Samsung Installed 0000002 Samsung NotInstalled 0000003 Xerox Installed 0000004 Brother NotInstalled 0000005 Brother NotInstalled 0000006 Brother NotInstalled 0000007 HP Installed 0000008 HP Installed And the result of my code is the following: Samsung - 2 Xerox - 1 Brother - 3 HP - 2 But I would like the code to count only elements with status "Installed". The result should be : Samsung - 1 Xerox - 1 HP - 2 How to improve the code? -
how to convert DateField field while returning a filtered result in DJANGO
I have the following table in django: models.py class Activity(models.Model) name = models.CharField(max_length=50) date_created = models.DateField() here is the way i create an instance of that table from datetime import date Activity.objects.create(name="Foo", date_created=str(date.today())) I know that auto_now_add=True can be used to store the date but at the moment it's out of the question and I need to find a solution exactly like the models is above. Is there a way to format the date_created field while querying all instances of the table Activity using .values() below in the views.py views.py activity = Activity.objects.filter(name="soccer").values() I am currently getting the following error: TypeError: Object of type date is not JSON serializable activity = Activity.objects.filter(name="soccer").values() -
Issue with complex lookup in Django
Below are my Django models. I'd like to write signal that will do the following: User updates project that contains let's say 3 Spider objects. Each Spider object contains config_file so signal should get list of all Spider objects and update group from all config files from the list. In the end when the user updates group name in Project all config_files should change group name as well. class Project(models.Model): name = models.CharField(max_length=200, default="") user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, default='') is_shared = models.BooleanField(default=False) group = models.ForeignKey(Group, on_delete=models.CASCADE, null=True, blank=True, default=1) class Spider(models.Model): name = models.CharField(max_length=200, default="", unique=True) user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, default='') project = models.ForeignKey(Project, on_delete=models.CASCADE, blank=True, null=True, related_name='project_spider') config_file = models.ForeignKey(BaseFileModel, on_delete=models.SET_NULL, null=True, default='') class BaseFileModel(models.Model): file = models.FileField(upload_to=custom_upload_files, null=True, default='') group = models.ForeignKey(Group, on_delete=models.CASCADE, null=True, blank=True, default=1) version = models.IntegerField(default=1) I tried to write pre_save signal but it doesn't work as expected because file field in BaseFileModel is null after spider.config_file.save() and not all config files have group updated. The problem I have is that there is no direct connection between BaseFileModel and Project and I am not sure how to write lookup/query to update all config files after updating project group. @receiver(pre_save, sender=Project) def update_spiders_group(sender, instance, … -
how do i prepopulate a dynamic html template for updating a instance
I'm trying to prepopulate the text fields in a form template with an existing instance, I can select the instance and can even user {{instance}} to see the variables but unfortunately can't figure out how to fill in the fields with the instance vars. If i do instance.cpacity for example it will display the correct value but in every field, and as this must be dynamic i need to make it so that each field has its own text box and is prepopulated, ive managed to do this with it being dynamic for "create "but i am struggling with this Sorry for the spelling punctuation and grammar, I am dyslexic Template.html as you can see the {{instance}} in the middle is where my input would be views.py my example input in views.py again i tried using the instance in the context but i dont know what html functions can help me get the neccesary variables in the loop! -
Custom header "X-API-Version" throws CORS error Django REST framework
I tried to add a custom header called "X-API-Version" to check if the front-end is up to date, but despite following the documentation instructions I got a CORS error. Access to XMLHttpRequest at 'http://192.168.5.39:8001/api/host/login/' from origin 'http://localhost:9000' has been blocked by CORS policy: Request header field x-api-version is not allowed by Access-Control-Allow-Headers in preflight response. I already installed the django-cors-headers package, added it to INSTALLED_APPS, added 'corsheaders.middleware.CorsMiddleware' and 'django.middleware.common.CommonMiddleware' in MIDDLEWARE and I also added x-api-version to CORS_ALLOW_HEADERS and CORS_ORIGIN_ALLOW_ALL = True but the error still persists. What could I do to prevent this error from happening? Is there another way to add a custom header?

Django provide value for baseuser_ptr
I'm learning django and I want to have my custom user and admin object but I'm encountering an error when I run makemigrations. I'm not sure if this is the right approach to do this so do enlighten me if I'm following the wrong approach. On one of my questions someone mentioned that I should only have one child of the AbstractBaseUser class but I really want to separate the customer model and the admin model. So I have created an app called 'core' where I want to do authentication stuff so that's where I've put my custom and admin user models.

Django Heroku app using Postgres : django.db.utils.ProgrammingError: relation already exists
In my Django app which is hosted using Heroku I am trying to migrate from Sqlite to Postgesql. I have migrated all of my data from the Sqlite database to the Postgres database but I am having problems with executing queries using the Django ORM. When executing a simple query such as Item.objects.all() I get an error telling me that the table does not exist. django.db.utils.ProgrammingError: relation "App_item" does not exist When i run python manage.py migrate then it displays No migrations to apply. which would imply that all models / tables have been migrated from my old Sqlite database to my Postgres database? As well as this, when inspecting the schemas through PG-Admin4 all models appear, so I am really not sure how it can't find my tables. models.py class Item(models.Model): item_id = models.CharField(max_length=20, primary_key=True) item_name = models.CharField(max_length=210) ... .. settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'legosite_DB', 'USER':'postgres', 'PASSWORD':'xxxxx', 'HOST':'127.0.0.1', 'PORT':'5432', } } -
Add Django model parent class to an existing "child" model for multi-table inheritance
I would like to add a new parent class to an existing model, which inherits from the same "super" parent class. Example of initial condition: from django.db import models class Ticket(PolymorphicModel): name = models.CharField(max_length=50) company = models.CharField(max_length=80) price = models.CharField(max_length=10) class MovieTicket(Ticket): # functions and logic For my implementation, I would like to add an "intermediary" EntertainmentTicket model, which inherits from Ticket and is inherited by MovieTicket for logic grouping purposes. Desired final condition: class Ticket(PolymorphicModel): name = models.CharField(max_length=50) address = models.CharField(max_length=80) price = models.CharField(max_length=10) class EntertainmentTicket(Ticket): # some functions and common logic extracted class MovieTicket(EntertainmentTicket): # logic unique to MovieTicket Note that the child classes have the same fields as Ticket, they only contain functions and logic. I cannot make Ticket into abstract, because I have other models pointing to it in a foreign key relationship. I use django-polymorphic to return the appropriate ticket type. I have made migrations for EntertainmentTicket, what are the right steps to take in writing custom migrations? -
"Why is my Django API returning an empty list of days for routines instead of a complete nested object with exercises and notes?"
I am having trouble getting a complete array of routines with each routine having multiple days, each day having multiple exercises, and all exercises having series, repetitions, cadence, and notes.

Ajax based drop down menu in Django admin
Please find the models and requirements below. As we can see from the models below, tags belong to a particular station. I am adding/editing data in these 2 models in a single page (as shown in the screen shot below), through my app’s Django admin. My requirement is when I choose a station name from a drop down, all the tags related to this station should load via AJAX automatically. Currently I am choosing a station name and I click save and continue editing in Django admin and after the page refresh all tags for that station name gets loaded. Waiting for the page refresh to load all tags belonging to a station name is very time consuming when adding details in bulk. Hence looking for ways to make an AJAX call every time the station name changes so that the tags are pulled and send back to the admin form asynchronously. Any suggestions is appreciated.

Override Django filter when searching for list of values in one property
I have simple GroupViewSet, which allows to filter Group objects by id and parent. Everything works as expected. I would like to expand functionality by allowing filter by multiple parents. Something like /api/groups/?parent=1&parent=2. The problem is that returned list is filtered only by last provided parent value. So in my example returned queryset will be filtered by parent=2. How can I override filter for list of values while preserving its other functionality. class GroupViewSet(ModelViewSet): queryset = models.Group.objects.all() serializer_class = serializers.GroupSerializer filter_backends = (DjangoFilterBackend) filterset_fields = ('id', 'parent') def get_queryset(self): parent_ids = self.request.query_params.getlist('parent') if len(parent_ids) > 1: return self.queryset.filter(parent__in=parent_ids) return self.queryset -
How to set different custom fields for articles in different article categories in Django?
I am a python rookie. I am using Django 4.X to create some basic CMS functions. The features I expect are: custom article classification, custom fields within article classification, and the ability to add different field contents based on user needs when adding articles in different categories. For example, Category 1: In addition to adding titles and article content, users also need to add weather information, while Category 2: users need to add price and quantity in addition to titles and article content. Here are the features I have already implemented and successfully run: Article publishing Article classification Custom fields within article classification Here is the feature I am unable to implement: When the user enters the page from post/int:category_id/add/, they should be able to add an article with the specific category ID and see the input fields for the custom fields I have added for that category ID.

Adding prerequisite to course sections
I am using the Tutor + OpenEdx open source platform and am looking to be able to set the prerequisite requirement for the individual sections as you can see this is already possible with the subsections but do not think there's an option for the individual sections. For example in the screenshots attached would like to have "Python" and "C++" locked until the student has completed "Intro to Programming". Think this is only possible with the subsections and not the sections at the moment so would like to build a plugin for it (or make changes to the code) to allow one to do the same with the sections. Would anyone be able to provide guidance on how to make this possible? -

Cannot use fetch with Django: blocked by CORS policy although CORS is set up in Django
There are many solutions on SO for this problem. Some are extremely detailed (e.g. this one). However, although I think I have followed the setup instructions explicitly, I still cannot get it to work. Can someone please point out my error? js let endpoint = 'http://192.168.4.28:8000/test-put' const form_data = new FormData(); form_data.append("payload", payload); await fetch(endpoint, { credentials: "include", method: "PUT", body: form_data, headers: { "X-CSRFToken": getCookie("csrftoken"), }, }) urls.py path('test-put/', views.TextPut.as_view()), views.py class TextPut(View): def put(self, request): return {} settings.py ... CORS_ALLOWED_ORIGINS = [ 'http://localhost:8888', ] CSRF_TRUSTED_ORIGINS = [ 'http://localhost:8888', ] ... INSTALLED_APPS = [ ... 'corsheaders', ... ] ... MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', ... 'django.middleware.common.CommonMiddleware', ... ] This produces the error: Access to fetch at 'http://192.168.4.28:8000/test-put' from origin 'http://localhost:8888' has been blocked by CORS policy: Response to preflight request doesn't pass access control -
Django: Deployment to different companies using the same project?
If, for example, ten people from different companies want to use my Django site. I think, I need a different database per company. Does this means ten different Django projects/instances being deployed? With different domains and separate databases? This seems unmanageable if one needs to update the code. (I am using PythonAnywhere a d mySQL but I don't care what I use in the end, just that I do this the right way so I don't end up with a major problem. I am looking to keep it as simple as possible to start and learn.) To all, what is your method to handle the 'selling' on a subscription basis a website to different organization while keeping everything organized? An example is a CRM program. If I an employee wants to see all the notes about Customer A, I don't want them seeing customers from different companies when I query to get .all(). So I am guessing I need different databases, deployments etc. . . Thank you, I don't even know what to search on Google to read about this or else I probably wouldn't be asking it here.
