"Waiting list" or delay when sending emails with Django and the win32 library
I have just discovered something in the provided code, and I would like to explain it to you. During my tests with the email sending using this code, everything seemed to work correctly, but a specific issue arose. Let's say I have three emails to send: email 1, email 2, and email 3. When I send email 1, the console returns a 200 OK status, but the email doesn't reach my inbox. Then, when I proceed to send email 2, the console again returns a 200 OK status, and although a new email appears in my inbox, it turns out to be email 1. After waiting several minutes without receiving any updates or new emails, I proceed to send email 3. At this point, the console once again shows a 200 OK status, and, surprisingly, I receive a new email in my inbox, but now it is email 2. ` class ApiSendMailCreateNewReporter(APIView): def get(self, request, id_headerRequest): try: # Obtener el objeto HeaderRequest o devolver un error 404 si no existe header_request = get_object_or_404(HeaderRequest, id=id_headerRequest) # Serializar el objeto HeaderRequest serializer_header_request = HeaderRequestSerializer(header_request) usuario_id = serializer_header_request.data['id_user_id'] require_date = serializer_header_request.data['require_date'] customer = serializer_header_request.data['customer'] # Obtener la instancia de Engineers con role='admin' o … -
Why Is a migration file created (over and over) when i run makemigrations
Am facing a somehow funny issue...every time i migrate,i get this description Your models in app(s): 'organization_app' have changes that are not yet reflected in a migration, and so won't be applied. Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them. so i follow what django says and i makemigrations,this migration file is created # Generated by Django 4.2.3 on 2024-02-07 20:14 from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ("organization_app", "0002_alter_penaltymodel_tenant_penalty_choice"), ] operations = [ migrations.AlterField( model_name="penaltymodel", name="tenant_penalty_choice", field=models.CharField( choices=[("PERCENT", "Percent"), ("AMOUNT", "Amount")], default="AMOUNT", max_length=20, ), ), ] when i migrate,i get the same description i stated earlier 'manage.py makemigrations' and when i migrate, the same migration file is created over and over..is this a #bug -

The problem of using the Arabic language in django links

CDN imports for PDF.js viewer.html in Django templates
I am trying to add the PDF.js viewer as it appears in the official demo in an HTML iframe of my Django template. I do not want include any of the assets of PDF.js in my repository and I want all my script and stylesheet HTML tags to refer to a CDN resource. Since the documentation contains a note that users of the library should not just copy/paste the web/viewer.html, I have created my own modified version named custom_viewer.html, which includes a subset of the features of the official demo. The prebuilt version of the library includes the following four tags in the demo web/viewer.html: <link rel="resource" type="application/l10n" href="locale/locale.json"> <script src="../build/pdf.mjs" type="module"></script> <link rel="stylesheet" href="viewer.css"> <script src="viewer.mjs" type="module"></script> My question is what are the corresponding CDN links to get this working without downloading the PDF.js library on the server? I have managed to replace the pdf.mjs file reference with a CDN link. More specifically, I have verified that when I copy the prebuilt PDF.js (version 4.0.379) in my static folder and I modify the paths as follows: {% load static %} <link rel="resource" type="application/l10n" href="{% static 'my-django-app/pdfjs-4.0.379-dist/web/locale/locale.json' %}"> <script src="https://cdn.jsdelivr.net/npm/pdfjs-dist@4.0.379/build/pdf.mjs" type="module"></script> <link rel="stylesheet" href="{% static 'my-django-app/pdfjs-4.0.379/web/viewer.css' %}"> <script src="{% static … -

Django background tasks - problem with process_tasks
I have a strange case and don't know how to solve it. Namely I have installed Django background tasks, made a migration and added to installed aps. I run python manage.py process_tasks in the terminal, open a second terminal and runserver. Everything is ok. In the admin panel I see: Completed Tasks and Tasks. The first terminal listens all the time for the execution of the task and when I let it go it works perfectly. However, if I enter Completed Tasks or Tasks in Admin while the task is running, the first terminal immediately stops listening and goes back to waiting for the prompt. Anyone perhaps know what this is all about? -
Django Rest Framework New User Registration with Admin activation
in the old Django times I was able to set the is_activated hidden field per registration of the user data to let the new user to registrate but not able tro login. An admin needed to activate the account - perfect. With the django rest framework I can't find a possibility to do the same action. Can I get a hind please .... thank you very much. Other maybe stupid question of this - how can I prevent the user from login without validation ( not Email validation ) Thanks a lot Greetings RR I tried successfully to add a user with all the methods I found online but always is_active was true Also it looked that the framework is always taking this field as true because its an admin feature to deactivate accounts - but this is the same I like to do. -

Restrict output of fields in Django admin according to previous selection

I'd like to limit the choice of schemes that can be selected from the admin form for project to only the schemes that belong to a specific funder. Is that possible? Example: in 'new project', people select funder1, and only see scheme1, scheme3, scheme5 in the drop-down for scheme, because scheme2 and scheme4 are associated to funder2. Is this something that can be obtained with a QuerySet?

How to implement HMTX with Django Class Based Views
I am trying to understand how to utilise htmx with Django Class Based Views. To provide some context, here is a reflection of the scenario in which I want to implement django class based views and htmx together: I have an initial view, which renders the main template and initial context. As part of this initial context, I am including a date form. I want to use htmx to post the data from this form to an APIView (let’s call it APIView1). I would like APIView1 to ingest the data which is posted to it via htmx, run a function on it, and then return data back as context, while rendering a partial template (let’s call it PartialTemplate1) which utilises that context. So from what I understand, I can do this within a get() function; so it may look a little like this: views.py Class InitialView(View): template_name = “initial_template.html” form_class = date_form def get(self, request, *args, **kwargs): … date_form=self.form_class() context = { 'date_form': date_form } return render(request, template_name, context) Class APIView1(APIView): template_name = “PartialTemplate1.html” def get(self, request, *args, **kwargs): date = request.POST.get(‘date’) timeslots = function(date) context = { ‘timeslots’: timeslots } return render(request, template_name, context). initial_template.html: <form hx-post='{% url "appname:apiview1_url" … -
Warning: Received `true` for a non-boolean attribute `crossOrigin` when using NextJS/React + Django Rest Framework
I've been receiving this warning but have little idea where it may originating from or how to solve it. It appeared seemingly out of nowhere. I went back a few commits and the warning still appeared, although I'm certain it was not present when I was initially working on those commits.

I'm actually looking for a way to do all the processing in the save method this is my Media model: title = models.CharField(max_length=255, null=True, blank=True) file = models.FileField(upload_to="upload/") filename = models.CharField(max_length=255, null=True, blank=True) mime_type = models.CharField(max_length=255, null=True, blank=True) thumbnail = models.JSONField(null=True, blank=True) size = models.FloatField(null=True, blank=True) url = models.CharField(max_length=300, null=True, blank=True) thumbhash = models.CharField(max_length=255, blank=True, null=True) is_public = models.BooleanField(blank=True, null=True) def save(self, *args, **kwargs): sizes = [(150, 150), (256, 256)] media_path = f"media/upload/{self.filename}" image = Image.open(media_path) mime_type = image.get_format_mimetype() format = mime_type.split("/")[1] if not os.path.exists("media/cache"): os.makedirs("media/cache") thumbnail = {} for i, size in enumerate(sizes): resized_image = image.resize(size) index = "small" if i == 0 else "medium" file_path = os.path.join( "media", "cache", f"{self.id}-resized-{self.filename}-{index}.{format}", ) resized_image.save(file_path, format=format) thumbnail["*".join(str(i) for i in size)] = file_path self.mime_type = mime_type self.size = os.path.getsize(media_path) self.thumbnail = thumbnail self.url = f"http://127.0.0.1:8000/media/upload/{self.filename}" … -
How to have multiple email backends in Django?

how to change the django connection string with postgres in each request in order to have a record of changes
Good afternoon, I have a trigger in my database that records every change, inclusion or deletion in the tables, but instead of using the user ID connected to Postgres, I would like to pass the user ID of my application, as it is an application SASS, I will have "a user" for the database, and "n" for the application. Is there any way to pass this user to my connection? where can I retrieve it in the trigger by executing select * from pg_stat_activity? I know the solution may seem inelegant, but it provides a lot of reliability when auditing data in the database I'm using: Django 4.2 DRF 3.14.0 Postgres 16.1 I tried to change the DATABASE parameters of settings.py, before the connection and I even managed to change the application_name, but when two users execute their requests "at the same time", there is a conflict and the two connections have the same value in the application_name. -

Issues with Database Router Configuration in Django for Handling Multiple Databases
I am working on a Django application that utilizes two databases: Primary Database: This is set as the default database and is primarily used for read-only operations, such as querying analytics data. It does not handle authentication or any write operations. Secondary Database (sqlserver_db): This database is used for write operations, including migrations and authentication-related tasks. I am encountering difficulties in configuring the database router in my settings.py to properly direct read and write operations to the appropriate database. Below is my current setup: I am struggling to set the database router in my settings.py file below is what I have done in settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.oracle', 'NAME': 'AAAA', 'USER': 'AAAA', 'PASSWORD': 'AAAA', 'HOST': 'AAAA', 'PORT': 'AAAA', 'OPTIONS': { 'threaded': True, }, }, 'sqlserver_db': { 'ENGINE': 'mssql', 'NAME': 'AAAA', 'USER': 'AAAA', 'PASSWORD': 'AAAAA', 'HOST': 'AAAAA', 'PORT': '', 'OPTIONS': { 'driver': 'ODBC Driver 17 for SQL Server', }, } } DATABASE_ROUTERS = ['MyApp.routers.AuthRouter'] and there in routers.py : class AuthRouter: """ A router to control all database operations on models in the auth and contenttypes applications. """ route_app_labels = {"auth", "contenttypes"} def db_for_read(self, model, **hints): """ Attempts to read auth and contenttypes models go to auth_db. """ …
