Getting 'Something went wrong' on form submission in Django signup view
I am experiencing an issue in my Django project's signup view. When I submit the form, the console prints 'Something went wrong,' and the user is not created. I have a custom User model, and the signup view appears to be correctly handling form data. However, despite thorough checks of my code, I'm unable to identify the root cause of the problem. --views.py from django.shortcuts import render, redirect from .models import User def signup(request): if request.method == 'POST': name = request.POST.get('name', '') email = request.POST.get('email', '') password1 = request.POST.get('password1', '') password2 = request.POST.get('password2', '') if name and email and password1 and password2: user = User.objects.create_user(name, email, password1) print('User created:', user) return redirect('/login/') else: print('Something went wrong') else: print('Just show the form!') return render(request, 'account/signup.html') I have also made the following settings: AUTH_USER_MODEL = 'account.User' --models.py import uuid from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, UserManager from django.db import models class CustomUserManager(UserManager): def _create_user_(self, name, email, password, **extra_fields): if not email: raise ValueError('You did not provide an valid e-amil address') email = self.normalize_email(email) user = self.model(email=email, name=name, **extra_fields) user.set_password(password) user.save(using=self._db) return user def create_user(self, name=None, email=None, password=None, **extra_fields): extra_fields.setdefault('is_staff', False) extra_fields.setdefault('is_superuser', False) return self._create_user_(name, email, password, **extra_fields) def create_superuser(self, name=None, email=None, password=None, **extra_fields): … -

DRF override default router path
When i register viewset in SimpleRouter i get paths like [get] objects/ [post] objects/ [get] objects/{id} etc. Is there a way to replace default post route with its detailed version? like [post] objects/{id} I've tried to replace it with action in viewset @action(detail=True, methods=['post'], url_path="my-path"): def my_action: ... but all i've got is [post] /objects/{id}/my-path and default post path is still there -
how to delete cache on my VPS Ubuntu Server. Whatever I write on any page is never shown
This is driving me insane. No matter what I do on the pages nothing is shown. Even if I write "hello" on my index.html page it will not show it. The server only shows what I pulled from github a week ago. Nothing, no change. I added the sentry logging tool, it takes zero notice, I copied pasted the logging snippet used and it completely ignores it. I write an extra word on the menu bar at the top, nothing is shown. -
drf-yasg: how to skip some operations during generate_swagger
I use Django with drf-yasg. I have a REST endpoint similar to the following: @swagger_auto_schema( method="POST", request_body=... ) @api_view(["POST"]) def do_something(request: Request) -> HttpResponse: ... When I run the server, I see the do_something operation in /swagger panel, which is fine. Now, when I run ./manage.py generate_swagger I would like do_something operation to NOT show in the resulting OpenAPI yaml. I would like to be able to somehow annotate the operation to be conditionally included, like with some custom @include_conditionally decorator: @include_conditionally @swagger_auto_schema(...) @api_view(["POST"]) def do_something(request: Request) -> HttpResponse: ... I know that setting auto_schema=None prevents the endpoint from being included in Swagger, but it excludes the endpoint from both Swagger web panel and the yaml schema, which I do not want. I tried to use my own generator in ./manage.py generate_swagger -g MyGenerator class MyGenerator(OpenAPISchemaGenerator): def should_include_endpoint(self, path, method, view, public): ... while should_include_endpoint seems to be the right way to go, I failed to detect if the operation was annotated with include_conditionally. Background: I want to exclude some of the endpoints from being exposed with Google ESP while being available locally. How can I exclude some endpoints conditionally from being included in Swagger schema yaml file? -
Re-translate Django
Django comes translated in my language however it's not complete and I don't like some of the translated phrases (personal preference). So I set the locale folder up and run python manage.py makemessages -l fa_IR and I get the file django.po but when I open it, I find that the phrases that are already translated and included with Django are not there. So looks like I have to edit (for example) \venv\Lib\site-packages\django\contrib\auth\locale\fa\LC_MESSAGES\django.po but if I ever update Django package of this project, all my edits will be lost, right? Is there any other solution? -

Django models, filter based on the division of two fields
I am having trouble understanding the annotate of django models. I am trying to build a datatable where one of its value is the division of two fields that might contain zeros and filter the rest based on the user input so what I tried so far is: model from django.db import models from django.utils import timezone class Item(models.Model): item_name = models.CharField(max_length=200) item_price = models.FloatField(default=0.0) unit_per_item = models.FloatField(default=1) description = models.TextField(default='') is_active = models.BooleanField(default=True) is_deleted = models.BooleanField(default=False) date_added = models.DateTimeField(default=timezone.now) views from django.db.models import Q, F, Case, When, FloatField from .models import Item if request.POST['search[value]']: model_obj = Item.objects.annotate( unit_price = Case( When(Q(item_price__exact=0) | Q(unit_per_item__exact=0), then=0), default=F("item_price") / F("unit_per_item"), output_field=FloatField() ) ).filter( Q(item_name__icontains=request.POST['search[value]'])| Q(item_price__icontains=request.POST['search[value]'])| Q(unit_per_item__icontains=request.POST['search[value]'])| Q(description__icontains=request.POST['search[value]'])| Q(unit_price__icontains=request.POST['search[value]']) )[start:length] But I am getting an error that says RegisterLookupMixin.get_lookup() missing 1 required positional argument: 'lookup_name' What I am essentially trying to achieve here in SQL is this SELECT *, item_price/unit_per_item AS unit_price FROM inventory_item WHERE item_name LIKE '%some_value%' OR item_price LIKE '%some_value%' OR unit_per_item LIKE '%some_value%' OR description LIKE '%some_value%' OR CONVERT( CASE WHEN item_price=0 OR unit_per_item=0 THEN item_price ELSE item_price/unit_per_item END, CHAR) LIKE '%some_value%'; I am honestly a little lost at this point, if there is a documentation that can expound further … -

(CRUD) Inventory System with Sub-inventories in DJANGO
This CRUD is basically a Main Inventory(a), which is going to be used by the inventory manager to feed workers inventories(b,c,d..)... When I try to transfer an item from A to B, the item gets transferred successfully, however, if item already exists, it still creates a new one, duplicating the Item several times. For Example: If a subinventory has "2 Screws", I add "3 Screws". Now the Subinventory has "2 Screws, and "3 Screws", instead of having now "5 Screws". The Models: Main Inventory class Articulo(models.Model): id = models.AutoField(primary_key=True) nombre = models.CharField(max_length=50) descripcion = models.CharField(max_length=100, null=True) costo = models.IntegerField(null=True) cantidad = models.IntegerField(null=True) medida = models.CharField(max_length=20) fecha_ingreso = models.DateTimeField(auto_now_add=True, null=True) fecha_salida = models.DateTimeField(auto_now_add=True, null=True) ubicacion = models.CharField(max_length=50, default='Almacen') SubItem and Subinventory class articuloInventario(models.Model): articulo = models.CharField(max_length=50, null=True) cantidad = models.IntegerField(null=True) medida = models.CharField(max_length=20, null=True) fecha_ingreso = models.DateTimeField(auto_now_add=True, null=True) ubicacion = models.IntegerField(null=True) class brigadaInventario(models.Model): id = models.AutoField(primary_key=True) articulos = models.ManyToManyField(articuloInventario) Views: def transferir_articulo(item_id, quantity): item_a = get_object_or_404(Articulo, id=item_id, cantidad__gte=quantity) item_b = get_object_or_404(articuloInventario, id=item_id, cantidad__gte=quantity) inventario = articuloInventario.objects.all() for b in inventario: if item_a.nombre == b.articulo: item_a.cantidad -= quantity item_a.save() b.cantidad += quantity b.save() return JsonResponse({'mensaje': f'{quantity} items transferred from inventory A to inventory B.'}) item_a.cantidad -= quantity item_a.save() item_b.cantidad += quantity item_b.save() … -

Unable to Commit Changes in Django Project When Including External Repository with Sass Partials
I am working on a Django project where I need to incorporate an external repository containing Sass partials for styling. To achieve this, I performed a git clone of the Sass partials repository into my Django project's repository. However, I've encountered an issue where any commits I make do not include the folder from the cloned Sass partials repository. It seems like the changes within the cloned repository are not being tracked or committed within the main Django project. Here are the steps I took: Cloned the Sass partials repository into my Django project: git clone <repository_url> Checked that the Sass partials folder is present within my Django project. Made changes to the Sass files and attempted to commit: git add . git commit -m "Made changes to Sass files" However, the commit does not include the changes made in the Sass partials folder. Additionally, I would like to emphasize that I do not want the changes made to the Sass partials to be committed within the Django project. I intend to maintain the Sass partials repository as a template only. I suspect there might be something related to the submodule behavior, but I want to ensure that the changes … -

Django ValueError: Cannot assign "<SimpleLazyObject: <User: gouri24>>": "HotelConfirm.username" must be a "userLogin" instance
I am encountering a ValueError in my Django project when trying to assign a user instance to the username field of the HotelConfirm model. The error message is: "Cannot assign "<SimpleLazyObject: <User: gouri24>>": "HotelConfirm.username" must be a "userLogin" instance."

AsyncWebSocketConsumer not receiving shell responses in Django Channels with Paramiko
I am working on a Django Channels application that utilizes the AsyncWebSocketConsumer to establish a WebSocket connection for SSH communication using Paramiko. The async_server_to_client method works correctly when called within the connect method but fails to receive shell responses when called within the receive method. I have attempted to use await sync_to_async and loop.run_in_executor to handle the synchronous get_recv method within the asynchronous context, but the issue persists. The WebSocket connection is established successfully, and data can be sent to the server, but the responses from the shell are not being received and forwarded to the WebSocket client. I also tried to print self.session.recv(1024).decode() but it returns the same command which I've sent from receive method. My whole code: from channels.generic.websocket import AsyncWebsocketConsumer from paramiko import SSHClient, AutoAddPolicy, RSAKey from asgiref.sync import sync_to_async, async_to_sync from channels.db import database_sync_to_async import json from .models import RemoteServer import socket import asyncio class WebSSH(AsyncWebsocketConsumer): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.session = None @database_sync_to_async def get_remote_server_info(self): server = RemoteServer.objects.get(id=self.rs_id) pkey = RSAKey(filename=server.key_file.path) return { "hostname": server.host_address, "port": server.port, "username": server.username, "pkey": pkey, "timeout": 10, } async def async_ssh_connect(self, server_info): client = SSHClient() client.set_missing_host_key_policy(AutoAddPolicy()) await sync_to_async(client.connect)(**server_info) transport = await sync_to_async(client.get_transport)() session = await sync_to_async(transport.open_session)() await … -

Uploading large file to GCS with django and django-storages -- direct or multi-part uploads?
I'm creating a django application that uploads multimedia to Google Cloud Storage using django-storages. My application is running on Google App Engine. Right now I'm having trouble with models that contain a large number of images -- for example, some of my models contain several 4K images, and at 25MB/ea I'm easily hitting hundreds of MB per save operation. django-storages is working great for smaller operations, but larger operations are causing issues. I'm currently getting an HTTP 413 error on larger save operations -- my app is POSTing about 100 MB, and Google App Engine's limit is 32MB. So my question is: to get around the limit, is it possible to make multiple POST requests using django-storages? Like, if my model has 4x 4K images, can I upload them each in a sequential upload? I've also read that I should upload files "directly" to GCS -- is it possible to do a "direct" upload using django? How would I go about doing that? thanks! -
How to create callback page for oauth with nextjs with a django grapql backend

unable bring footer down in wagtail and in Django html
In Django, if the footer renders correctly on sub-pages but not on the main page, you should examine the main page template and related files. Check for potential issues in the HTML structure, template blocks Verify that the main page correctly extends the base template and includes the footer within the appropriate block. Additionally, inspect any conditional logic or specific settings in the footer.html file that may affect its rendering. Ensure consistency in the template hierarchy and investigate any page-specific configurations that might impact the footer display. By addressing these aspects, you can troubleshoot and resolve the discrepancy in footer rendering. <section class="py-4 mt-lg-5 mt-0" style='background-color: #814EBF; background-image: url("{% static 'images/contact-overlay.png' %}");'> <div class="container"> <div class="row align-items-center"> <div class="col-lg-8 text-lg-left text-center"> <h2 class="h2 cc-contact-footer-h2"> Global CTA Title </h2> <p class="cc-contact-footer-p mb-0"> Lorem ipsum dolor sit amet, consectetur adipisicing elit.

I need this field to accept more than one value selected by the user to be saved in the database.I don't think I know where to move. models.py: `from django.db import models from django.contrib.auth.models import AbstractUser from courses.models import CourseCategory from multiselectfield import MultiSelectField class CustomUser(AbstractUser): areas_of_interest_choices = ( ('TI', 'Tecnologia da Informação'), ('ADM', 'Administração'), ('CTB', 'Contabilidade'), ('EC', 'Economia'), ('FI', 'Finanças'), ('SA', 'Saúde'), ('LI', 'Linguagens'), ('GA', 'Gastronomia'), ) escolaridade_choices = ( ('FC', 'Fundamental Completo'), ('FI', 'Fundamental Incompleto'), ('MC', 'Médio Completo'), ('MI', 'Médio Incompleto'), ('SC', 'Superior Completo'), ('SI', 'Superior Incompleto') ) full_name = models.CharField(max_length=50, null=False, blank=False) cpf = models.CharField(max_length=11, verbose_name='CPF', blank=False, null=False) date_of_birth = models.DateField(blank=True, null=True, verbose_name='Data de Nascimento') email = models.EmailField(max_length=100, blank=False, null=False) telephone = models.CharField(max_length=11, blank=False, null=False, verbose_name='Telefone') zip_code = models.CharField(max_length=8, blank=False, null=False, verbose_name='CEP') education = models.CharField(max_length=2, choices=escolaridade_choices, verbose_name='Escolaridade') areas_of_interest = MultiSelectField(blank=True, null=True, max_choices=3, max_length=5,choices=areas_of_interest_choices) def __str__(self): return self.username ` forms.py: `from django.contrib.auth.forms import UserCreationForm, UserChangeForm from .models import CustomUser, CourseCategory from django import forms class CustomUserCreationForm(UserCreationForm): class Meta: model = CustomUser fields = ("username", … -
Why would a check constraint be violated on a cascade delete?
When I delete an object ('item') in my Django app, a related object (in another table) that points to it via a foreign key should also get deleted due to its "on_delete=models.CASCADE" setting. But the cascade delete is failing because of a check constraint on the related model: MySQLdb.OperationalError: (3819, "Check constraint 'item_or_container' is violated.") My question is, why would a check constraint be triggered on a delete? Does Django modify the record somehow before deletion? The record in question does pass the constraint, and if I just delete that record directly it works as expected; it only fails during a cascade delete. The "violated" constraint is as follows: models.CheckConstraint(check=Q(item__isnull=False) ^ Q(is_container=True), name='item_or_container') (Which is an XOR ensuring that an object can EITHER have an assigned item OR be a container - not both.) My expectation is that both records should simply be deleted. Thank you for your help! -
