how can I modularize this code to reuse the AJAX in different HTML files without needing to rewrite it each time?
I separated my JavaScript code from the .html file and placed it in a static folder, then imported it. However, after this change, my AJAX stopped working. How can I make my ajax.js reusable across different pages without rewriting it? This was the working code that handled the editing of classes, receiving, and processing files. I should mention that I’m working on a Django project, and this is the first JS file I’m including in the project. The idea of separating it is so that the same AJAX functionality can be used for the adicionar_aula URL. Here is the code: ` Editar Aula Editar Aula {% csrf_token %} {{ form.as_p }} Arquivos já adicionados: {% for arquivo in arquivos_existentes %} {% if arquivo.arquivo %} {{ arquivo.arquivo.name }} {% else %} Arquivo não disponível {% endif %} Excluir {% empty %} Nenhum arquivo adicionado ainda. {% endfor %} Adicionar Arquivo Salvar Alterações $(document).ready(function() { // Enviar novos arquivos via AJAX $('#input-arquivo').on('change', function() { var formData = new FormData(); $.each($(this)[0].files, function(i, file) { formData.append('arquivo', file); }); formData.append('csrfmiddlewaretoken', '{{ csrf_token }}'); $.ajax({ url: '{% url "editar_aula" pk=plano.id %}', // URL para a view de edição type: 'POST', data: formData, processData: false, contentType: false, … -
Remove the mandatory field label 'This field is required.' and fix the bug with 'clean_email'
I use the built-in Django, 'UserCreationForm' to create a registration form, but there are unnecessary instructions 'This field is required.' that these fields are required, I want to remove them, please help, or at least translate into Russian, so that the inscription is in Russian, if you can, also help fix clean_email in forms, so that it does not always throw out this inscription after 1 test entry of an existing email here is a screenshot of the result RegisterUserForm views.py: class RegisterUser(CreateView): form_class = RegisterUserForm template_name = 'users/register.html' extra_context = {'title': 'Регистрация'} get_success_url = reverse_lazy('users:login') forms.py: class RegisterUserForm(UserCreationForm): username = forms.CharField(label="Логин:", widget=forms.TextInput(attrs={'class': "form-input"})) password1 = forms.CharField(label="Пароль:", widget=forms.PasswordInput(attrs={'class': "form-input"})) password2 = forms.CharField(label="Повтор пароля:", widget=forms.PasswordInput(attrs={'class': "form-input"})) class Meta: model = get_user_model() fields = {'username', 'email', 'first_name', 'last_name', 'password1', 'password2'} labels = { 'username': 'Логин:', 'email': 'E-mail:', 'first_name': 'Имя:', 'last_name': 'Фамилия:', 'password1': 'Пароль:', 'password2': 'Повторить пароль:', } widgets = { 'username': forms.TextInput(attrs={'class': "form-input"}), 'first_name': forms.TextInput(attrs={'class': "form-input"}), 'last_name': forms.TextInput(attrs={'class': "form-input"}), } def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.order_fields(['username', 'email', 'first_name', 'last_name', 'password1', 'password2']) def clean_email(self): email = self.cleaned_data['email'] if get_user_model().objects.filter(email=email).exists(): raise forms.ValidationError(("E-mail должен быть уникальным!"), code="invalid") return email users/register.html: {% extends 'users/base.html' %} {% block title %}Регистрация{% endblock %} {% block content %} … -
Question about creating a CRUD API for a project
how’s it going? This isn’t a coding question, but if anyone can help, it would be great. I’m new to this and I want to create an API that does a CRUD as a project. I’ve seen it’s recommended to do this, but of course, creating a public API allows anyone to modify the database. My question is: when recommending to create an API as a project, are they referring to a FakeAPI? I mean, should actions like DELETE or PUT only be temporary while the session is active? I’ve been trying to understand this so I can get started on the project. Thanks for your attention. -

403 Forbidden POST Request when trying to log out using React front end with Axios and Django with rest-framework
I keep getting an 403 Forbidden error when trying to log out of the user account. I am able to log in fine, I see in the cookies that there is a sessionID and a csrf token. However every single time without fail I get a 403 forbidden error when trying to log out. I have withCredentials:true and include the csrf token in the header. I have my middleware in the right order, I have all the correct cors-headers configuration and allowed hosts. When inspecting the network details using F12 I can see that the sessionID cookie is not being sent along with the csrf token. Not sure why? I am at my wits end. Here is my code for the login and logout front end as well as relevant settings.py code and views.py for logout. Axios: import axios from "axios"; axios.defaults.xsrfCookieName = 'csrftoken'; axios.defaults.xsrfHeaderName = 'X-CSRFToken'; const client = axios.create({ baseURL: "http://127.0.0.1:8000", withCredentials: true, }); export default client; Login: function submitLogin(e) { e.preventDefault(); client.post("/api/login/", { username, password }, { withCredentials: true, }) .then(function(res) { if (res.data.redirect_url) { navigate(res.data.redirect_url); } else { console.error("No redirect URL provided."); } }) Logout: function logout(e) { e.preventDefault(); const csrftoken = document.cookie.split('; ').find(row => row.startsWith('csrftoken='))?.split('=')[1]; … -
How to handle prefixed UUIDs in Django Admin for querying and displaying objects?
I am working on a Django project with a custom UUIDField with a prefix (e.g., ft_) to represent IDs. The raw UUID is stored in the database, but I want the prefixed value (e.g., ft_) to be shown in API responses, admin interfaces, and elsewhere. However, this creates issues when querying objects in Django Admin because the URLs include the prefixed ID, and Django tries to query the database directly using this prefixed value. Here is my custom field implementation: import uuid from django.db import models class PrefixedUUIDField(models.UUIDField): def __init__(self, prefix, *args, **kwargs): self.prefix = prefix super().__init__(*args, **kwargs) def from_db_value(self, value, expression, connection): if value is None: return value return f"{self.prefix}_{value}" def get_prep_value(self, value): if isinstance(value, str) and value.startswith(f"{self.prefix}_"): value = value.split(f"{self.prefix}_")[1] return super().get_prep_value(value) def to_python(self, value): if isinstance(value, uuid.UUID): return f"{self.prefix}_{value.hex}" if isinstance(value, str) and not value.startswith(f"{self.prefix}_"): return f"{self.prefix}_{value}" return value The model: class FamilyTree(models.Model): id = PrefixedUUIDField(prefix="ft", primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=255) In Django Admin, the URL for editing an object looks like this: http://admin.localhost:8000/family_tree/familytree/ft_5F5479ca65374d401d9466d57fc95e4072/change/ However, this causes the following error: invalid input syntax for type uuid: "ft_5F5479ca65374d401d9466d57fc95e4072" I understand this happens because Django Admin tries to query the database using the prefixed id, but the database … -
Column 'tbl1.id' is not the same data type as referencing column 'tbl2.field_id' in foreign key 'tb1_field_id_tbl2_id'
I have a problem with migrations. I'm using database which was created with old Django version 1.4 in new application with Django version >5. The problem is that old Django is using different data type for primary key field (AutoField - int in database). So in database datatype of old django's primary key is "int" and in the new Django datatype is "bigint". I've created new model with Foreign Key to old model and now I'm facing an error: Column 'tbl1.id' is not the same data type as referencing column 'tbl2.field_id' in foreign key 'tb1_field_id_tbl2_id' How can I solve this problem? Only thing that help is to assign db_constraint=True in the models.ForeignKey field. But I don't want have this risk. -
Suggestion of Django "email queue" package for current versions?
I found the django-mail-queue and django-email-queue packages, which are several years old yet appear to be well-used. But, as recently discussed here moments ago, I ran into unexpected migration issues. (And, with help, I think solved them.) But I'd like to ask if anyone has a better suggestion – for current Django, current MySQL and so-on. "I just want: 'It Just Works.™'" No migration quibbles, and so on. I want to simply be able to queue email-only messages and then send them with a periodically-scheduled 'manage' subcommand. That's it, that's all. The above-cited packages will work for me, but the migration issue startled me. -
Why do I have to create a new thread for updating a database record? (Django Rest Framework)
I'm using Django Rest Framework for creating an API. The idea is that the user uploads some data using a POST request. This data is uploaded to a database. Once uploaded, a new Python thread is created, running some operations on said data. Then when operations have finished, the result is written to the original database record. Using this approach the API remains accessible, while also working on the operations in the background. The user can check the operations status using a GET request. For some reason, when trying to update the record with the operation results, I got the following error: SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async It was confusing, since the operation and updating function was already running using a thread. I would not get the error when substituting the operations with some simple mock-up test results (strings). Not even when using time.sleep() for a longer period than the actual operations would take. So I suspect the problem has something to do with the operations I'm running, even though they do not interact with Django whatsoever. I fixed the problem by creating new threads specifically for saving the updated … -
Django alterfield migration to textfield fails
The migration for Django package django-mail-queue contains the following in relevant part: migrations.AlterField( model_name='mailermessage', name='to_address', field=models.TextField(db_index=True, verbose_name='To'), ), But it fails on MySQL 9.0.1 (Django 5.1.5) with the following error: django.db.utils.OperationalError: (1170, "BLOB/TEXT column 'to_address' used in key specification without a key length") Any idea why? I found a closed bug-report for Django (from some years ago) in which this kind of AlterField request had problems, but it appears to be unrelated. -

Django DRF API endpoint can be called via Postman but gives back 404 not found in pytest
I'm currently rewriting our Django unit tests (written with django.unittest library) in pytest, and I'm encountering an issue. I use a separate conftest.py file where I store my pytest fixtures and also load my JSON fixtures to fill the database with test data. One of my pytest fixture methods creates a user, and another one creates an authorized client. The user fixture also takes db as an argument. That's basically the base setup. The test method calls an endpoint that includes the user_id in the URL. The call looks something like: response = authorized_client.get(path=f"/user/{user_id}", headers=header) Testing the endpoint manually in Postman gives back the user data and a 200 status code. However, pytest returns a 404 status code. User.objects.exists(id=user_id) This confirmed that the user exists in the database. I investigated further and called the endpoint that retrieves all users. The user_id I used in the call to the endpoint was not included in the response. I suppose that's why I get a 404 back. The Question Why do I get User.objects.exists(id=user_id) but the user with that ID is not actually there when I call the endpoint? Does pytest handle test database isolation differently than django.unittest so that the viewset can't … -

Issue with Django CheckConstraint
I'm trying to add some new fields to an existing model and also a constraint related to those new fields: class User(models.Model): username = models.CharField(max_length=32) # New fields ################################## has_garden = models.BooleanField(default=False) garden_description = models.CharField( max_length=32, null=True, blank=True, ) class Meta: constraints = [ models.CheckConstraint( check=Q(has_garden=models.Value(True)) & Q(garden_description__isnull=True), name="garden_description_if_has_garden", ) ] The problem is that when I run my migrations I get the following error: django.db.utils.IntegrityError: check constraint "garden_description_if_has_garden" is violated by some row But I don't understand how the constraint is being violated if no User has a has_garden, the field is just being created and also its default value is False 🤔. I'm using django 3.2 with postgresql. What is the proper way to add this constraint? If it's of any use here's the autogenerated migration: # Generated by Django 3.2.25 on 2025-01-15 23:52 import django.db.models.expressions from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ("some_app", "0066_gardenuser"), ] operations = [ migrations.AddField( model_name="user", name="garden_description", field=models.CharField(blank=True, max_length=32, null=True), ), migrations.AddField( model_name="user", name="has_garden", field=models.BooleanField(default=False), ), migrations.AddConstraint( model_name="user", constraint=models.CheckConstraint( check=models.Q( ("has_garden", django.db.models.expressions.Value(True)), ("garden_description__isnull", True), ), name="garden_description_if_has_garden", ), ), ] -

I am trying to create a django web app for displaying various data (a question and some additional data).My data consists of a question body and industry guidance, which contains several bullet points. Each bullet point may contain additional sub options itself as well, etc. Example data: Question body: Was everyone familiar with the location, purpose, testing and oepration of fire doors?
