Django keeps returning local variable 'product' referenced before assignment error
I stored a list of products in my django models with multiple images attached to each product as a foreignkey. I am trying to retrieve all the products and their respective images in my django views so that I can print them on the screen. However no matter what I do I keep getting the local variable 'product' reference before assignment error. Models.py: class product(models.Model): title = models.CharField('', max_length=100, db_index=True) price = models.CharField('', max_length=100, db_index=True) description = models.CharField('', max_length=100, db_index=True) class productimage(models.Model): product = models.ForeignKey(product, on_delete=models.CASCADE) product_images = models.FileField(blank=True) views.py: template = loader.get_template("selling/shop.html") if product.objects.exists(): products = product.objects.all() for product in products: productimages = product.productimage_set.all() for productimage in productimages: imageurl = productimage.product_image.url context = { "products" : products, "productimages" : productsimages, } -
DRF Viewset - Do not create but return if object already exists
Is it possible to override the create of a Viewset to first check if an object exists and, if so, return that object rather than creating it? Specifically, in my viewset, I have overriden the create function as follows: def perform_create(self, serializer): try: item = Item.objects.get(recipe=serializer.instance.recipe) except Item.DoesNotExist: serializer.save(owner=self.request.user) However, this always fails as the object cannot be found. When I print serializer.instance it is undefined. -

Combine and filter unrelated models
I have a few vehicle types (cars, planes, trains) with distinct models and want to have an API endpoint that will give me a filterable list of all the models combined. I've modified a ViewSet's list method to combine the serialized results of each models ModelViewSet and serve them through one endpoint. The format of the response is correct, but I want to be able to filter it. I have tried the endpoint with about 50,000 randomly generated vehicles (evenly spread across the models) and the unfiltered response can be very slow.

Django database dropped and cannot re-migrate
For reasons best not explained, I deleted all tables in the database for my personal Django project. I thought running makemigrations and migrate would set it back up, however the migrate command fails. Running python manage.py migrate results in: django.contrib.auth.models.DoesNotExist: User matching query does not exist. I can run the server. However when going to the admin page (http://127.0.0.1:8000/admin/), I get the exception: During handling of the above exception ('SessionStore' object has no attribute '_session_cache'), another exception occurred: The above exception (relation "django_session" does not exist LINE 1: ...ession_data", "django_session"."expire_date" FROM "django_se... ^ ) was the direct cause of the following exception: The request information shows "[unable to retrieve the current user]". Checking the PostgreSQL database in pgAdmin 4 shows that there are no tables, as expected. Is Django noticing I don't have any users in the database? Is there a way to set up the admin user again? -

Candidates model: class Candidates(models.Model): nom = models.CharField(max_length = 50) prenom = models.CharField(max_length= 50) email = models.EmailField() phone = models.CharField(max_length=100) niveau_d_experience = models.IntegerField() etablissement_universitaire= models.CharField(max_length=150) niveau_options = (('Licence', 'Licence'), ('Master', 'Master'), ("Diplôme d'ingénieur", "Diplôme d'ingénieur"), ('Doctorat', 'Doctorat')) niveau_educatif = models.CharField(choices=niveau_options, max_length=100) profil = models.CharField(max_length=100) sexe_options = (('Mâle', 'Mâle'), ('Femelle', 'Femelle')) sexe = models.CharField(choices=sexe_options, max_length=100) offre = models.CharField(max_length= 200) CV = models.FileField() date_creation = models.DateTimeField(auto_now_add=True, auto_now=False) text_resume = models.TextField(editable=False) language = models.CharField(max_length = 20, editable=False) Offers model: class Offers(models.Model): titre = models.CharField(max_length=120) description = models.TextField() technologies = models.TextField() softskills = models.TextField() expérience = models.IntegerField() contrat_options= (('CDI', 'CDI'), ('CDD', 'CDD'), ('Freelance', 'Freelance'), ('Stage', 'Stage')) contrat = models.CharField(choices=contrat_options, max_length=100) mission_options = (('Interne', 'Interne'), ('Externe', 'Externe')) mission= models.CharField(choices=mission_options, max_length=100) validation_options = (('Offre validée', 'Offre validée'), ('Offre pourvue', 'Offre pourvue')) validation = models.CharField(choices =validation_options, max_length=100) def add_line(self, **kwargs): queryset = Candidates.objects.all() for … -
Why the attribute of an instance model does not change
I create a financial manager and I need the user to change the account activity (indicate an active account or not), but when I send the form for change, then the model attribute does not change and always remains TRUE I also tried to do this through a copy of the Account, but it was also not a result of the outcome Account.objects.get(user=self.request.user, id=id).is_active = False models.py class Account(models.Model): type_of_currency = models.CharField(max_length=20) user = models.ForeignKey(get_user_model(), blank=True, related_name='user_account', on_delete=models.CASCADE) count = models.DecimalField(max_digits=12, decimal_places=2, blank=True) created = models.DateTimeField(default=datetime.datetime.now) is_active = models.BooleanField() def __str__(self): return f'{self.type_of_currency} - {self.count}' views.py class AccountDetailView(DetailView, UpdateView): model = Account form_class = AccountCreateForm template_name = 'account_detail.html' def post(self, request, *args, **kwargs): id = self.request.POST['accountid'] self.request.user.user_account.get(id=6).is_active = False print(self.request.user.user_account.get( id=id).is_active) # always True why? return redirect('/counts/' + id) template {% extends 'base.html' %} {% block content %} <div class="col-sm-5"> <h1>account: {{ account.id }}</h1> <p><strong>Author:</strong> {{ account.user }}</p> <!-- author detail link not yet defined --> <p><strong>Type:</strong> {{ account.type_of_currency }}</p> <p><strong>count:</strong> {{ account.count }}</p> <p><strong>IsCreated:</strong> {{ account.created }}</p> <p><strong>IsActive:</strong>{{ account.is_active }}</p> <a class="btn btn-outline-primary" href="{% url 'account-list' %}">Back</a> {% if account.is_active %} <form method="post"> {% csrf_token %} <input type="hidden" value="{{ account.id }}" name="accountid"> <button type="submit" class="btn btn-outline-danger">Deactivate</button> </form> {% else … -
Handle Custom User Model Django-Allauth
I have a custom User Model that extends from Django's User and I want to register that user model instead of only the default one. For this, I am using the ACCOUNT_SIGNUP_FORM_CLASS setting as per allauth doc. This is what I have in settings.py: ACCOUNT_SIGNUP_FORM_CLASS = 'myapp.forms.SignupForm' And in myapp/forms.py: class SignupForm(UserCreationForm): class Meta(UserCreationForm.Meta): model = MyUser def signup(self, request, user): print('test') user.save() MyUser(user=user).save() The signup() function should be executed: This class [SignupForm] should implement a def signup(self, request, user) method, where user represents the newly signed up user. But it isn't (test is not printed). Only User is saved, MyUser isn't. What am I doing wrong? -
