Exporting Django models to Excel (different sheets) using Django-tables2
I've checked django-tables2 documentation, however I haven't find an easy way to export models to different sheets in Excel. To make it simple, let's suppose I have two different models: Sales and Products. I would like to export an excel document with two different sheets: Sales and Products. I can export the first model with the code shown below, but I'm not sure if there's a way to export the Products model to another sheet. Any help would be appreciated. export_format = request.GET.get('_export', None) if TableExport.is_valid_format(export_format): table = [[Sales Table Object]] exporter = TableExport(export_format, table) return exporter.response('File_Name.{}'.format(export_format)) ``` -
Django multitenant using middleware - can you persist connections
I'm using django with django-tenants for a SaaS app and it is using the user's subdomain to set the db schema in postgresql. So a call to user1.app.com will use the 'user1' schema. Each call to a view creates a new database connection by default. If the view call ajax, a new connect/disconnect happens. Using this method works as each call gets it's postgresql search path set to the correct schema using the django-tenants middleware. My question is if I set CONN_MAX_AGE to persist connections for a period of time to reduce the heavy connect/disconnect load on the server, will django pool connections from multiple users potentially using different schemas? I am concerned, because: All users are using the 'default' DATABASE. (just the search path changes) I don't see any logic that binds a connection to a unique user session. The built in development server ignores the CONN_MAX_AGE setting so I can't test locally. I have looked into the connection_created signal, but I would be duplicating logic with django-tenants and I'm not sure of any unintended consequences. Using django 4.0.7 and posgresql 12 Any insight or suggestions are appreciated. -
How to set another instance as foreign key on delete in django?

How I can use Nested serializer in Django Rest Framework

Why i have already installed modules in my virtualenv?
I have globally installed modules in my pc, but when i create a virtualenv some of the modules are already preinstalled in it, but when i execute 'pip freeze' in my virtualenv there are no installed modules. commands like 'django-admin' , 'cookiecutter' already work in my virtualenv though i have never installed them in it. But other commands like 'numpy' or 'pandas' do not work , though i have installed them in my machine globally like django or cookiecutter. How do i fix this? I am using python version 3.9.6. -
Django DM model constraint: uniqueConstraint or checkConstraint?
I am trying to define a unique constraint for my DB model. I have 3 constraints and have no trouble with 2. But the 3rd one is doing my head a little. So the model class is fairly simply; its a social media connection request model (between user accounts). These are the constraints I am trying to enforce: User1 should have only one connection request to User2: UniqueConstraint works fine. User1 should not be able to send a connection request to User1 (ie self): CheckConstraint works fine. If User1 sends a connection request to User2, then User2 should not be able to send a connection request back to User1: this is the one I am struggling with. How can I enforce the 3rd constraint here? I initially thought the 1st one enforces the reverse constraint actually (where the uniqueness of the 2 entries in the table are enforced regardless of the order) but it doesnt seem it like (and makes sense too). class ConnectionRequest(models.Model): senderAccount = models.ForeignKey( Account, related_name='sender_Account', on_delete=models.CASCADE) recipientAccount = models.ForeignKey( Account, related_name='recipient_Account', on_delete=models.CASCADE) requested = models.DateTimeField(auto_now_add=True) def __str__(self): return str(self.senderAccount.id) + ' to ' + str(self.recipientAccount.id) class Meta: constraints = [ # duplicate connection request constraint models.UniqueConstraint(name='duplicate_connreq_constraint', … -

Django updating username results in unusable password. How to prevent this?
I am using code to update the user details and whilst the values are updating I have noticed that when I update the username, which is an email address, the password is set to an unusable password, as if set_unusable_password() were used. If I don't update the username but change the first_name and last_name everything is fine. Why? And how can I stop this behaviour? User.objects.filter(username=username).update( first_name=first_name, last_name=last_name, username=username/new_user_name, ) FYI, this is base User model in django. -
Django Rest Framework when doing a POST getting TypeError at Function.objects.create()
I have the following model class Funcion(models.Model): idPelicula = models.ForeignKey(Pelicula, on_delete=models.PROTECT) idSala = models.ForeignKey(Sala, on_delete=models.PROTECT) horaEntrada = models.TimeField(auto_now=False, auto_now_add=False) horaSalida = models.TimeField(auto_now=False, auto_now_add=False) fecha = models.DateField(auto_now=False) And the next serializer class FuncionSerializer(serializers.ModelSerializer): pelicula = PeliculaSerializer(read_only=True) idPelicula = serializers.PrimaryKeyRelatedField(write_only=True, queryset=Pelicula.objects.all(), source='pelicula') sala = SalaSerializer(read_only=True) idSala = serializers.PrimaryKeyRelatedField(write_only=True, queryset=Sala.objects.all(), source='sala') class Meta: model = Funcion fields = '__all__' When I try to post a new Funcion with the Django api root I get the following error: TypeError at /funcion/ Got a `TypeError` when calling `Funcion.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `Funcion.objects.create()`. You may need to make the field read-only, or override the FuncionSerializer.create() method to handle this correctly. I have used this method before for other project practices and it worked correctly. If i delete the source='pelicula' argument for the PrimaryKeyRelatedField() it post the new funcion but when I do a get to bring al the data it doesn't show the Pelicula or Sala field just the rest I tried deleting those arguments because the error at the end shows this message TypeError: Funcion() got unexpected keyword arguments: 'pelicula', 'sala' -
Filters for CBV ListView using GET from Previous and Current Page
I am trying to add search functionality to a ListView in two places in my Django application. From the homepage, I want users to be able to filter by zip code, and on the ListView template, I also want users to have the ability to filter by another attribute in the model. My issue is that the self.request.GET.get('q') returns None when filtering from the ListView page, and I want it to retain the zip code filter that I used in the previous page. For search functionality, I am using Q. How can I retain the zip code filter from the initial request so that I can query on both zip code and category? views.py class ListingsView(ListView): model = Listing template_name = 'listings/list.html' context_object_name = 'listing_list' def get_queryset(self): query_zip = self.request.GET.get('q_zip_code') query_category = self.request.GET.get('q_category') if query_category == None: queryset = Listing.objects.filter(Q(zip_code__icontains = query_zip)) else: queryset = Listing.objects.filter(Q(zip_code__icontains = query_zip) & Q(category__icontains = query_category)) return queryset home.html <p> <form class="form-homepage-search" action="{% url 'rental_listings_list' %}" method="get"> <input name="q_zip_code" class="form-zip" type="text" placeholder="Zip Code" aria-label="Zip Code"> <button class="button" type="submit">SEARCH</button> </form> </p> list.html <form class="form-listing-search" action="{% url 'rental_listings_list' %}" method="get"> <input name="q_category" class="form-category" type="text" placeholder="Category" aria-label="Category"> <button class="button" type="submit">UPDATE</button> </form> -
Persisting external classes in Django
I am working on a Django application that uses the SimpleGmail package to fetch mails from a Gmail inbox and I need to persist them. Normally I'd have written a model for the class, but given it's an external class, I can't figure out how to cleanly persist it. I have come across solutions such as making it an attribute of a new model that is persisted or multiple inheritance of the desired class, but none of these seem correct to me. How do I properly register an external class as a model for Django's persistence? -
How to use timezone.now() in django with activate timezone?
I am using Django 3.2 and changed my setting.py as TIME_ZONE = 'Asia/Calcutta' USE_I18N = True USE_L10N = True USE_TZ = True and try to use timezone.now() It gives me the UTC time when I print it from my view.py It worked well for DateTimeField in models when I store some data into it.

irregular arbitrarily Cross-Origin request blocked error in Django on Ionos hosting
I am currently making a project for school where I made a quiz. The quiz is supposed to evaluate in the front-end, which works perfectly fine, and after that it should send the information to the backend. The Backend should save the details to the database and after that it should send the information back to the front end. The front end should show a message with some details about how you passed compared to all the others, the information are the one from the database. So, the weird thing about all that is, that it works sometimes and sometimes not... If I test it at the local host, the code works perfectly fine, the error only occurs on the Ionos server (I got a hosting contract so I do not have access to the console...).

I do not really undersand why it is like that def ProductCreateView(request): context = {} created_product = None form = ProductForm() if request.method == 'POST': form = ProductForm(request.POST) if form.is_valid(): created_product = form.save() print("Successfully created new product: {}".format(created_product)) else: print("form is not valid") #print(request.POST) returns csrfmiddlewaretoken ... #print(request.FILES) returns file : inmemoryuploadedfile ... #print(list(request.POST.items())) context['form'] = form formset = ProductPhotoInlineFormset() if request.method=='POST': formset = ProductPhotoInlineFormset(request.POST or None, request.FILES or None, instance=created_product) if formset.is_valid(): created_images = formset.save() print("Successfully created new imagest: {}".format(created_images)) else: print("formset is not valid") context['formset'] = formset return render(request, "Ecommerce/create_product_test.html", context) my template - create_product_test.html {% extends 'base.html' %} {% block content %} <div id="alert-box"> </div> <div id="image-box" class="mb-3"> </div> <div id="image-box"></div> <div class="form-container"> <button class="btn btn-primary mt-3 not-visible" id="confirm-btn">confirm</button> <form method="POST" enctype="multipart/form-data" action="" id="image-form"> {% csrf_token %} <div> {{form}} {{formset.management_form}} {{formset.as_p}} </div> </form> </div> {% endblock content %} forms.py file ProductPhotoInlineFormset = inlineformset_factory( Product, Photo, fields=('file',), form=PhotoForm, extra=1, ) where is the problem ? -
Two exactly same repositories but different result
Sorry for this weird question but my mind went blank. I can install a script from its original Github repo (project1) in an Ubuntu server: I clone the original repo and start installation in the server, no problem at all. However if I create a repo (project2) in my GitHub account, then copy all the files (except .git) from the original repo (project1) to my new repo (project2), then clone my repo and start installation in the server, installation gives me an error. ango.db.migrations.exceptions.InvalidBasesError: Cannot resolve bases for [<ModelState: 'dictionary.MetaFlatPage'>] This can happen if you are inheriting models from an app with migrations (e.g. contrib.auth) in an app with no migrations; see https://docs.djangoproject.com/en/3.2/topics/migrations/#dependencies for more Those two repositories are the exactly same. I didn't change any file, any line. Do you know what possibly causes this issue? Script is a Django script.
