Creating a field thats connected with another in Django
The thing is that I'd like to create a field with a title that shows available titles depending on the artist's choice in the field above. For example, if a user selects "Drake" in the artist field, only the titles for that artist will be displayed in the title field. I'm completely stuck. Could you give me a hint how to solve the problem? I was wandering if I have to change my models.py by adding some kind of One-To-Many relationship or is there diffrent method? Webpage: enter image description here My models.py file: from django.db import models class SpotifyData(models.Model): title = models.CharField(max_length=60) rank = models.IntegerField() date = models.DateField() artist = models.CharField(max_length=60) region = models.CharField(max_length=20) chart = models.CharField(max_length=8) streams = models.IntegerField() class Meta: indexes = [ models.Index(fields=['title']), models.Index(fields=['rank']), models.Index(fields=['date']), models.Index(fields=['artist']), models.Index(fields=['region']), models.Index(fields=['chart']), ] My view.py file: import plotly.express as px import plotly.graph_objects as go from django.shortcuts import render from spotify_data.models import SpotifyData from spotify_data.charts import (make_song_rank_changes_chart, ) from typing import Any, Dict from django.views.generic import TemplateView from django.views.generic.list import ListView class HomeView(ListView): model = SpotifyData context_object_name = "record" def get_context_data(self, **kwargs: Any) -> Dict[str, Any]: context = super().get_context_data(**kwargs) context["records_all"] = SpotifyData.objects.all().count() return context class SongRankChangesChart(TemplateView): model = SpotifyData context_object_name = … -
Is it possible with Django to have a global view that is called on every page?
I was wondering if it is possible with Django to have a "global view" that is called on every page before all the initial views, for example to display additional information other than the user's information. All of this to avoid having to call a model on all of my views. To allow me to call it only once. -

Django How to use drf-yasg in class-base view which is parent of all other views to generate swagger docs?
I'm trying to add swagger to my project so drf-yasg was the option with @swagger_auto_schema, but I'm using a baseView view which is parent class view for all other views, thus all HTTP methods are written in baseView, so that children views doesn't need to implement these methods. the problem is that when I added @swagger_auto_schema to baseView methods it didn't see the child attributes but the baseView's attributes. The baseView: class BaseView(APIView): model = models.Model serializer_class = serializers.Serializer description = '' id = openapi.Parameter('id', in_=openapi.IN_QUERY, type=openapi.FORMAT_UUID) @swagger_auto_schema(manual_parameters=[id] ,responses={200: serializer_class},operation_description=description) def get(self, request, id=None, **kwargs): .... @swagger_auto_schema(request_body=serializer_class) def post(self, request, **kwargs): .... Then let's say I have this child view: class TestApi(BaseView): model = test description = 'This is test api' serializer_class = TestSerializer In this approach Swagger are show empty values for description and serializer_class because it doesn't see child values how to solve this without have to configure each view with HTTP methods and @swagger_auto_schema. thank you in advance. -

How to create a form with fields for all instances of another model in Django?
I'm new to Django and I'm currently trying to create a form which should contain input fields for all existing objects of another model. Let's say that I would like to manage my supplies at home and make sure that I have enough of various products at diffect storage locations. For example, I would like to make sure that the storage locations bathroom and basement should always have plenty of the supply toilet paper. I don't need toilet paper in the location kitchen. The storage locations are pre-defined and available through a model. I couldn't find any way to create a form for Supply which dynamically generates form fields for MinimumQuantity objects based on all available StorageLocation objects. My form should look like this when creating the supply "toilet paper": supply name: <input example: "toilet paper"> minimum supply quantities bathroom - amount: <input example: 6> kitchen - amount: <input example: 0> basement - amount: <input example: 3> I'm a bit lost here and any hints would be much appreciated. This is my current code (shortened): models.py: class Supply(models.Model): name = models.CharField(max_length=50) class StorageLocation(models.Model): name = models.CharField(max_length=50) class MinimumQuantity(MinimumQuantity): storage_location = models.ForeignKey(StorageLocation, on_delete=models.PROTECT) supply = models.ForeignKey(Supply, on_delete=models.PROTECT) amount = models.IntegerField() views.py: … -
How to transfer date from form to django code (datepicker form to value (htmx))?
Good good evening! I have a standard datepicker form. I'm trying to figure out how to take the start and end date values. At least one date value from the form to use in various Python calculations. I have a data table where the data is sorted by date. And I need to take only certain rows from the given table. Having values in code. I need to somehow capture the date value and send this value to the code. Maybe there are some modern methods for taking data from an html or htmx form? I have been thinking for a long time how and what can be done in order to take data from a form and put it into code for some kind of calculation processing. I would be very grateful for any hints, help. models.py from django.db import models class Offer(models.Model): expiration_date = models.DateField(null=True) forms.py from django import forms from django.forms import ModelForm from .models import Offer class DateInput(forms.DateInput): input_type = 'date' class OfferForm(forms.ModelForm): class Meta: model = Offer fields = fields = '__all__' widgets = { 'expiration_date': DateInput(), } template <form action="" enctype="multipart/form-data" method="POST"> {% csrf_token %} {{ form|crispy }} <input type="submit" name="submit" value="Submit"> </form> -

Waiting list db model desgin
I am creating a web app using Django, which ultimately will allow users to take up certain activity over some period of time. However, each day has a maximum capacity of users for an activity. This means, that all the activities requested for a given day, that are over this limit, should be put in a waiting list. Right now, my models are like this: Activity model: class Activity(models.Model): user = models.ForeignKey( 'User', related_name="user", ) activity_type = models.ForeignKey( "Activity_type", null=True, blank=True ) start_date = models.ForeignKey("Calendar") end_date = models.ForeignKey("Calendar") Calendar model: class Calendar(models.Model): date = models.DateField() limit = models.IntegerField() Please note that those are only fields relevant for the problem and there are more fields in those as well. As you can see, Activity entity has a start_date and end_date fields, which represent when the user will start and end his activity. Now, note that every DAY in the Calendar entity has it's own limit. This means, that we should put this activity to the waiting list but only for this day. How would you approach such a design? I thought of something like so: class WaitingList(models.Model): activity = models.ForeignKey('Activity') date = models.ForeignKey(Calendar) enlist_date = models.DateTimeField(default=datetime.now) But this means that if … -
Groupby using Django's ORM to get a dictionary of lists from the queryset of model with foreignkey

Here's a sample data: Business.objects.create(name="first company") Business.objects.create(name="second company") Employee.objects.create(business_id=1, name="Karol") Employee.objects.create(business_id=1, name="Kathrine") Employee.objects.create(business_id=1, name="Justin") Employee.objects.create(business_id=2, name="Valeria") Employee.objects.create(business_id=2, name="Krista") And I want to get a dictionary of lists, keys being the businesses and values being the list of employees. I can do so using prefetch_related on the Business model. A query like this: businesses = Business.objects.prefetch_related("employees") for b in businesses: print(b.name, '->', list(b.employees.values_list("name", flat=True))) Which gives me this: first company -> ['Karol', 'Kathrine', 'Justin'] second company -> ['Valeria', 'Krista'] And this is exactly what I want and I can construct my dictionary of lists. But the problem is that I only have access to the Employee model. Basically I only have a QuerySet of all Employees and I want to achieve the same result. I figured I could use select_related, because I do need the business objects, but this query: Employee.objects.select_related("business") Gives me this QuerySet: <QuerySet [<Employee: Employee object (1)>, <Employee: Employee object (2)>, <Employee: Employee object (3)>, <Employee: Employee object (4)>, <Employee: Employee object (5)>]> And I don't … -
