DRF mixin uses the model manager's create method but not the update method
# models.py class HelloManager(models.Manager): ''' On create, set date_created and last_modified to the same values On update, set last_modified to current time ''' def create(self, *args, **kwargs): current_time = datetime.now() kwargs.setdefault('date_created', current_time) kwargs.setdefault('last_modified', current_time) return super().create(*args, **kwargs) def update(self, *args, **kwargs): kwargs['last_modified'] = datetime.now() return super().update(*args, **kwargs) The CreateModelMixin works just fine, but the UpdateModelMixin does not call my manager's update method. I went through DRF's implementation and found that the UpdateModelMixin calls serializer.save() wich calls either update or create but this is where I got lost. I tried just directly overriding perform_create like so: # views.py class HelloDetailView(mixins.RetrieveModelMixin, mixins.UpdateModelMixin, generics.GenericAPIView): queryset = HelloModel.objects.all() lookup_field = 'id' def get_serializer_class(self): if self.request.method == 'POST': return HelloWriteSerializer return HelloReadSerializer def get(self, request, *args, **kwargs): return self.retrieve(request, *args, **kwargs) def post(self, request, *args, **kwargs): return self.update(request, *args, **kwargs) def perform_update(self, serializer): HelloModel.objects.update(**serializer.validated_data) But the problem now is the UpdateModelMixin now returns old data. What's the best approach for this? -
Related fields aren't filtering in the formset (using library 'django-formset' )
I'm trying to use the library 'django-formset' to filter drop-down list (ForeignKey objects) when selecting an item in a linked drop-down list (related ForeignKey objects). I think, I did everything according to the instructions, but still the data in the second drop-down list is not filtered. Maybe someone has experience using this library with formset? What I did: Model class TypeCar(models.Model): title = models.CharField(max_length=20) class Car(models.Model): reg_mark = models.CharField(max_length=10) type_car = models.ForeignKey( 'TypeCar', ... ) class Order(models.Model): car = models.ForeignKey( Car, ... ) type_car = models.ForeignKey( TypeCar, ... ) Form (FormSet): from formset.widgets import Selectize class OrderCloseForm(forms.ModelForm): type_car = forms.ModelChoiceField( label="Type_car", queryset=TypeCar.objects.all(), widget=Selectize( search_lookup='name__icontains', placeholder="First, select Type car" ), required=False, ) car = forms.ModelChoiceField( label="Car", queryset=Car.objects.all(), widget=Selectize( search_lookup=['title__icontains'], filter_by={'type_car': 'type_car__id'}, placeholder="Then, select a Car" ), required=False, ) class Meta: model = Order fields = ( 'type_car', 'car', ) Formset displays already existing objects in which need to make a selection of the above fields OrderCloseFormSet = modelformset_factory( Order, form=OrderCloseForm, extra=0, can_delete=False, ) Template <head> <link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}"> <link href="{% static 'formset/css/bootstrap5-extra.css' %}" rel="stylesheet"> <link href="{% static 'formset/css/collections.css' %}" rel="stylesheet"> <script type="module" src="{% static 'formset/js/django-formset.js' %}"></script> </head> <django-formset endpoint="{{ request.path }}" csrf-token="{{ csrf_token }}"> {{ formset.management_form }} {{ … -
Python Django does not see the CSS file
I just started using Django, which I initially had a lot of problems with, but that's not the point. I launched a new project about 4 times, it turned out that through the console it did not create a complete list of folders and files and I had to create them manually. I created and added an init file everywhere so that Python sees this folder, however, when I need to insert a Banner photo for my profile, when I start the server through the console and the python manage.py runserver command, although it launches my entire HTML structure, it does not display the photo , which I inserted there initially. I tried to change the location of the folders, I tried to change the location of the photos and it didn’t bring much results. Also, I changed settings.py and urls several times, but this also did not change anything, perhaps I made a mistake in the code or missed something? {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <meta http-equiv="X-UA-Compatible" content="ie=edge" /> <link rel="stylesheet" href="{% static 'css' %}" /> <title>Your Profile</title> </head> <body> <div class="container"> <div class="sidebar"> <div class="logo"><span class="tf-logo">{{ title … -
Using an object attribute when accessing element in array in Django Template Python
So basically in my Django template I'm passing in two things from my view. a Django model object Plan which is defined like: class Plan(models.Model): class Sport(models.IntegerChoices): RUN = 1, "RUNNING" CYC = 2, "CYCLING" SWM = 3, "SWIMMING" sport = models.PositiveSmallIntegerField( choices=Sport.choices, default=Sport.RUN ) start_date = models.DateField("Starting Date") end_date = models.DateField("End Date") weeks = models.PositiveSmallIntegerField(default=0) title = models.CharField(max_length=20) description = models.TextField(max_length=100, blank=True, null=True) completed = models.BooleanField(default=False) def __str__(self): return self.title and 2. an array of arrays of strava activities pulled from an API, activity_list which is formatted so activity_list[i][j] would return week i's activity on day j. In my template, I need to access activity_list dynamically whilst looping through the week numbers in the plan. My first attempt was to do something like ativity_list.week.number.0 to access the Monday of the week we're on, but as expected Django treats week.number as a literal instead of replacing it with the number "0" or "3" or whatever. I'm really stuck on this so any help would be much appreciated, either with an ad-hoc fix or a way to refactor my models to make this feasible. Thanks -

How to pass data to injected django template?
In django admin interface I have a custom tab for displaying a table. How to display the table as django admin model list table instead of field, but get the context for table from admin.py by calling the method from the model. I used django-baton's baton_form_includes to insert a template below the field, but then I could not pass data to that template. models.py class MyModel(TimeStampedModel): . . . def get_custom_tab_data(self): return OtherModel.objects.filter( active=False ) admin.py @admin.register(models.MyModel) class MyModelAdmin(): . . . readonly_fields = ( "get_custom_tab_data", ) fieldsets = ( _("Custom Tab"), { "fields": ("get_custom_tab_data"), "classes": ("tab-fs-custom") } ) . . # django-baton baton_form_includes = [("admin/custom_tab_template.html", "get_custom_tab_data", "below")] # This was the better solution but template table should display as model admin list with custom data, so had to use baton_form_includes to inject template above field. # def custom_tab_data(self, myModel: models.MyModel): # if myModel.active: # return "N/A" # if custom_data := myModel.get_custom_tab_data()[:15]: # get 15 latest # html_content = render_to_string( # "admin/custom_tab_template.html", # {"custom_data": custom_data} # ) # return mark_safe(html_content) @admin.display(description="Custom Tab") def get_custom_tab_data(self, myModel: models.MyModel): return self.custom_tab_data(account) custom_tab_template.html {% load i18n l10n %} <table class="table table-stripped"> <thead> <tr> <th>ID</th> <th>Name</th> <th>State</th> <th>Created</th> </tr> </thead> <tbody> {% comment %} {% … -

How to make a field unique across two models in Django without inheritance?
I have following 2 models, Admin and Employee: class Admin(models.Model): name = models.CharField(max_length=30) email = models.EmailField() city = models.CharField(max_length=30) def __str__(self): return str(self.name) class Employee(models.Model): name = models.CharField(max_length=30) email = models.EmailField() city = models.CharField(max_length=30) department = models.ForeignKey(Department, on_delete=models.CASCADE) def __str__(self): return str(self.name) What I want is to ensure that the field email is unique across both the models i.e. no two admins can have the same email AND no two employees can have the same email AND no admin and employee have the same email. I created a base class CustomUser and inherited it to both Employee and Admin class: class CustomUser(AbstractUser): email = models.EmailField(unique=True) class Employee(models.Model): name = models.CharField(max_lengt=30) email = models.OneToOneField(CustomUser, on_delete=models.CASCADE) city = models.CharField(max_length=30) department = models.ForeignKey(Department, on_delete=models.CASCADE) def __str__(self): return str(self.name) class Admin(models.Model): name = models.CharField(max_lengt=30) email = models.OneToOneField(CustomUser, on_delete=models.CASCADE) city = models.CharField(max_length=30) def __str__(self): return str(self.name) What I want to know is, is there any other way of ensuring this kind of cross-model uniqueness that wouldn't require me to create a separate Abstract class? -

View in django not running
I have a Django project where I'm trying to activate a user's account when they reset their password. I've created a custom view ActivateUserPasswordResetConfirmView that inherits from PasswordResetConfirmView and overrides the form_valid method to set user.is_active = True. However, the form_valid method in my custom view does not seem to be called when a user resets their password. I've checked my URL configurations and they seem to be correct. Here are the relevant parts of my code: views.py: from django.contrib.auth.views import PasswordResetConfirmView class ActivateUserPasswordResetConfirmView(PasswordResetConfirmView): def form_valid(self, form): user = form.save() user.is_active = True user.save() return super().form_valid(form) myapp/urls.py: from django.urls import path from .views import ActivateUserPasswordResetConfirmView urlpatterns = [ path('reset/<uidb64>/<token>/', ActivateUserPasswordResetConfirmView.as_view(), name='password_reset_confirm'), # other urls... ] project/urls.py: from django.urls import include, path urlpatterns = [ path('', include('myapp.urls')), path('accounts/', include('django.contrib.auth.urls')), # other urls... ] I have also added logging in the form_valid method, but I don't see any log messages when testing the password reset flow, which suggests that the method is not being executed. Any ideas on why the form_valid method is not being called or how I can debug this issue further? -
Technical question: Building API using python in real time connection + authentication
I need to build an API that will be called from Android, iOS and desktop clients using framework like flutter The problem i am facing is that i need to build an APIs that relies on HTTPS request/response that uses JSON format using python and offer some features like authentication, authorization, database storing, static files storing like.png and .pdf and some parts should work in real time connection for chat system but i don't know what should i use.

Need some advice on Phusion/Passenger setup
Okay, so.. I've never used this set of programs, so please be nice. I help a guy out with his hosted application on dreamhost. I mostly edit some HTML and python. However, it's pretty legacy and it's running phusion/passenger. It's a django site, but I don't think it's "deployed correctly" with django. Typically, I copy everything locally, make edits and run the application manually with something like: python manage.py runserver 0.0.0.0:8000 --verbosity 3 I then just copy over the changes.. However, some of the python modules are REALLY old. I wanted to try and update them. When I update django in my dev environment the application works fine. However, when I update django on the dreamhost environment the application bombs. (I do not have the exception handy) So, I want to more accurately reproduce this environment. I've built a docker container with apache, passenger, etc. I'd like to figure out how to put this application into the passanger environment so I can reproduce the environment. But I simple don't know how - and the amount of Googling i've done has not helped. -
Django: Set initial value of dropdown in form based on value in model
I am working on a ticketing web application using Django as a university.

Add dynamic fields through django admin
I've looked around the stack but I cant find any answers. So I have a model like this: class DynamicModel(models.Model): config = models.JSONField() def __str__(self): return self.config what I want to do here now is to show the json field key-value pairs as standalone fields and also be able to edit them in the same way, like if they were each one a different field. This was the best way I could come up to create dynamic fields. So if I have a jsonfield like this: { "age": 23, "name": "John Doe", "gender": "Male" } I would have an `Age` field where I can edit the value or even remove the field alotgether. The changes would then reflect to the `JSONField`. My approach is like this: # forms.py from django import forms from .models import DynamicModel class DynamicModelForm(forms.ModelForm): class Meta: model = DynamicModel fields = '__all__' def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # Check if 'config' is in the fields if 'config' in self.fields: # Extract JSON data from the instance or initialize an empty dictionary json_data = self.instance.config if self.instance and 'config' in self.instance else {} # Loop through the JSON data and add individual fields for key, value …
