Django, guidelines for writing a clean method for a ModelChoiceField
I have read the docs and I can only find guidelines on how to write a clean method for a field within a form: https://docs.djangoproject.com/en/3.1/ref/forms/validation/#cleaning-a-specific-field-attribute However I have created a field which inherits from ModelChoiceField. I wish to add some custom validation and cleaning, attached to the field and not the form, because the field is used in multiple forms, hence keeping it DRY. I can take a stab at creating a clean method, but eactly what args are passed in, and what should be returned seems to be lacking in the documentation, or I can't find it. Here my field that I wish to add custom cleaning and validation to: class FooChoiceField(forms.ModelChoiceField): def __init__(self, required=True): queryset = Foo.objects.filter(enabled=True).order_by('name') super().__init__( widget=forms.RadioSelect, queryset=queryset, to_field_name='id', # The radio button value field required=required, empty_label=None, ) self.error_messages = { 'required': "Please select a Foo.", 'invalid_choice': "Invalid Foo selected, please try again.", } # Pass the whole DB object into the template so one can access all fields def label_from_instance(self, obj): return obj Heres a guess at it? Is it good, bad? How about validation? def clean(self, value): if value != 'correct': raise ValidationError('Value is challenged in it's correctness') return value -
RuntimeWarning: DateTimeField received a naive datetime, with correct timezone and settings
I am receiving this error message: RuntimeWarning: DateTimeField Z.data_zal received a naive datetime (2020-11-05 07:13:24) while time zone support is active. warnings.warn("DateTimeField %s received a naive datetime (%s)" At this step of creating my models instance: views.py from django.utils import timezone t = Z(data_z=timezone.now().strftime('%Y-%m-%d %H:%M:%S'), data_r=data_r, author=request.user) try: t.save() So as far as I know this error occurs when using datetime module instead of timezone. Sometimes the problem lies in wrong settings.py but I am running: TIME_ZONE = 'Europe/Warsaw' USE_TZ = True What seems to be the issue? -
Datatables Pagination Does Not Show
What I'm trying to do is set up a table just like this: https://datatables.net/examples/basic_init/alt_pagination.html Copied the code but then no success.

View uploaded files for specific object in django
I want to upload files to a client. So when I check the client they all show the same uploaded files. How do I filter through the files to show only for the specific clients who have files added to them? Model: class Document(models.Model): client = models.ForeignKey(Client,on_delete=models.CASCADE, related_name='docs') title = models.CharField(max_length=50) docs = models.FileField() Views.py: def fileDetails(request,pk): files = UploadFile.objects.all() client = Client.objects.all() notes = Note.objects.all() docs = Document.objects.all() context = {'files':files,'client':client,'notes':notes,'docs':docs} return render(request, 'clients/file_detail.html',context) Forms.py: class DocumentForm(forms.Form): file_field = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple': True})) I tried using a filter but nothing shows on any of my queries. I just would like to see the docs updated on a client and not see the same for all. Might be something I missed or I'm overthinking this query. -

Is there any method of integrating ReactJS and Django without implementing Django Restful API?
Guys as you may know when using Vanilla JS you can just deliver html files to Django and just code between the lines in Python language in order to create the functionalities that you need in your backend side of your web application. However this is not the case when we use React JS. Is there any similar way(as vanilla JS and html files)for integrating REACT.JS and Django(except for using rest api endpoints)? -

Why is my API data nt showing up on my django html page?
I am fairly new to coding in general so apologies for my dumb question. I created an API in Node. I put some filler data in the DB and tested the API. Works fine. I created a Django app that attempts to access the data in the API. I am using a CORS module so I can access the API on my local machine. When I load the home page, a GET request is sent to the API, and I can see that the API receives the request. I don't know if any data is being sent back. Nothing shows up in the table on the home page. -API routes- (all routes are starting with /questions) router.get('/', queryQuestions); router.post('/', addQuestion); router.delete('/:uid', deleteQuestion); router.get('/:uid', queryQuestion); router.patch('/:uid', updateQuestion); -Django view- from django.shortcuts import render from django.shortcuts import redirect from django.contrib import messages def home(request): import json import requests api_request = requests.get("http://localhost:3000/questions") try: api = json.loads(api_request.content) except Exception as e: api = "Error..." return render(request, 'frontend/home.html', {'api': api}) Django template 'home' (sample) <table class="table table-striped table-bordered table-hover"> <thead class="thead-dark"> <tr> <th scope="col">ID</th> <th scope="col">Question</th> <th scope="col">Category</th> </tr> </thead> <tbody> {% if api %} {% for list_item in api %} <tr> <td>{{ list_item.uid }}</td> … -

Django run a function while exiting a view or navigating to a different URL from the current URL

Django profile image is incorrectly displaying the logged in user's image (on every profile)
Any assistance in this would be much appreciated. Problem: Logged in user image is displaying on every user's profile in Django 3.1 I extended the Django User model with a OneToOne relationship to another model called UserProfile, which contains an ImageField called profile_pic. Settings for root media folder are setup correctly in settings.py and referred to in root urls.py. Something is incorrect with the class-based view, a generic ListView to display a user's product posts, or I'm incorrectly referring to the profile_pic in the template. Any ideas on how to display each user's profile image on their associated userprofile? Currently, when a user is logged in, his/her image is displaying on every profile. models.py class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) profile_pic = models.ImageField(default='default_profile_pic.jpg', upload_to='profile_pics') class Meta: verbose_name_plural = "User Profiles" def __str__(self): return f'{self.user.username} UserProfile' def save(self, *args, **kwargs): super().save(*args, **kwargs) views.py class ProfileListView(ListView): model = Product template_name = 'users/profile.html' context_object_name = 'products' paginate_by = 12 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) # userprofile = UserProfile.objects.filter(user_id=userprofile) return Product.objects.filter(user=user).order_by('-creation_date') profile.html {% if user.userprofile.profile_pic %} <img class="rounded-circle" src="{{ user.userprofile.profile_pic.url }}" alt=""> {% else %} <img class="rounded-circle" src="media/default_profile_pic.jpg" alt=""> {% endif %} -
Limit Foreign Key Options in Django Select
I have a model for Supplier and another model for Product. Each Product must have a Supplier instance associated to it. Later on, in a separate model form for the Proforma model, the user has to select a Supplier and then a Product. What I'd like to see happen is the Product select options filter down to Products where the Supplier = the Supplier the user has selected. I am not finding much on how to handle this use case...could anyone point me in the right direction? Will this require the use of JS or can I do something to set this in the form directly? Or maybe pass a queryset from the view to this field? Anything even some resource on this would be helpful. models.py class Supplier(models.Model): supplierName = models.CharField(max_length=100) class Product(models.Model): code = models.CharField(max_length=100) supplier = models.ForeignKey(Supplier, null=False, blank=False) class Proforma(models.Model): ... supplier = models.ForeignKey(Supplier, null=False, blank=False, on_delete=models.CASCADE) code = models.ForeignKey(Product, null=True, blank=True, on_delete=models.CASCADE) -
Uploading image into ModelForm in Django?
I am having trouble uploading an image into with a form through Django. The file does not appear in my `templates/auctions' directory, nor does it render in my template (probably because it never uploaded).

My AuctionListing model in models.py has this field: image = models.ImageField(blank=True, upload_to="images/") and my project file settings.py has this configuration: MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' Is my commit=False in the views.py creating an issue? -
