How to sync smtp mailbox to local inbox
I am creating an email campaign system in which I have several connected accounts. I am fetching emails from SMTP periodically through IMAP.

Django ORM model 'save' method and race condition / ACID Isolation
if we examine the following code: class SomeModel(models.Model): ... def save(self, *args, **kwargs): self.validate_unique() super().save() def validate_unique(self, *args, **kwargs): super().validate_unique(*args, **kwargs) # Doing an ORM query on the model with *filter* on the model attributes & an associated model, # and if exist - dont create a new instance, if not - create a new instance. is_duplicated = SomeModel.objects.filter(name=given_name_from_user, attribute_from_associated_model=some_attr) if is_duplicated: raise Exception("go wrong") # Else - continue to save Now, it will work with the development server, but not with a production one like gunicorn or uvicorn, because the save method gurantee us atomicity, but not isolation, right? for us to gurantee isolation, we should use ‘get_or_create’ on the view level? I’m mistake somewhere? Any comment will help, Thanks! -
Should I put Django venv directory in .gitignore?
In my book Python Crash Course 2nd edition it is recommended to put ll_env (venv directory) in .gitignore. It says, "We tell Git to ignore the entire ll_env directory, because we can re-create it automatically at any time" But in my opinion this is a very bad move because I won't be able to roll back the installation of packages. Do I need to do it? Why? -
An appointment system [closed]
So basically I am trying to make a project for medical purposes in django. The projects is like there are some services like appointing for having a cold, having a daze, having a headache and... and also user can choose multiple services, like they can have a daze and catch a cold at the same time. There are 3 types of users, admin, patient and doctor. There are many Doctors and each doctor can do his own services. Also doctors can do several services that are chosen by patients and not only one, and in the end, I want the chosen services for the chosen doctor in the chosen appointment time to be shown after a payment in the homepage of the doctor And I have no Idea how to build such a system Would be thankful if you guys give me some idea about how can I do it and some examples I also tried to implement something like a system of buying a product which shows up after the payment for the admin, but I don't know how to show it for the doctor, and not only admin -

How to protect a top secret python script?
I'm developing a project in a client-server architecture. The client is a python 3.12 script that will run on customers desktops and the server is a Django 5.0.x application. I will distribute the client script after running pyinstaller -F script.py, so the package has approximately 40MB because of the virtual enviroment with python libs. So, I need to protect the client script to avoid people can read my code and copy my idea. I was thinking in to create an auxiliary script so this auxiliary script and server will do these basic steps: Auxiliary script generates an RSA assymetric keypair Auxiliary script sends the public key to django application. Django application encrypts the main script with this public key and return a response with encrypted main script as response Auxiliary script downloads the encrypted main script and decrypt with private key Auxiliary script loads the unencrypted main script into the memory Finally, auxiliary script execute the main script. The problem is, even I convert the auxiliary script to a binary by using pyinstaller, if someone do something and can read the auxiliary script code, so this person can edit the code and make the step 5) writes the main script … -
How do I set up a domain name stator page for a Django web server?

And I need to run it from the browser like this in the browser: dato138it.ru It all works on a cloud server timeweb.clouds. How do I set up a domain name stator page specifically for a Django web server? The problem is that a separate page from the Lamp web server is currently running. So the domain now sees this page from Lamp by default: dato138it.ru -
Interact with inbuilt django DB in python files
I have a form that needs to interact with the DB inbuilt into django. How would I do that in my forms.py file. Do I just use the default sqlite3 built into python or does django have a different way of doing it? I have written a basic post/get request on the frontend. On the backend, I just need to interact with the database. I do not want to use the inbuilt django auth system as I will need to access the database for other use cases also. Any help is appreciated! -
How to add CSS class to a ReCaptchaField v2 in Django forms

Playing an audio file on server from django
I have a raspberry pi that I have hooked up to a door chime sensor so it plays different sounds as people enter the building. Right now, I just made a short script to play those sounds from whatever is in a directory, and it works fine. I decided that it might be easier to upload sounds, and organize their play order if I setup a web server, and since I tend to use django for all web servers, I thought I could get it to work. I know it's a pretty big hammer for such a small nail, but I use it regularly, so it's easy for me to use. This code, when I put it in the django InteractiveConsole, plays just fine. When I try to call it from a PUT request in a view, it won't play the sound, but it also doesn't throw any errors. This is the case both on my computer and the pi. >>> import vlc >>> media_player = vlc.MediaPlayer() >>> media = vlc.Media("/home/pi/chime/media/clips/clip1.mp3") >>> media_player.set_media(media) >>> media_player.play() Is there something that would prevent these kinds of calls from running in a django view? Is there a way to work around it? -

Hired at a new job - I can do 85% of responsibilities except some things related to the website. How do I get a sitemap?
I am in charge of adding content to a website - it uses Wagtail. I know nothing about programming. My superior has asked me to do a website audit and wants to know if the sitemap file is set up correctly. My problem is that I do not know how to get a sitemap. On a broader level I have no idea who created the website or how to access the more complex areas (Django contrib sitemap app?) I apologize for being so ignorant but could anyone describe to me the first steps I should take? That might include questions I could ask the people around me to gain access to what I need to get to. -
Docker-compose is able to compile program but is unable to open link to Local host
I have a basic Django project that I have put into a docker container. Currently I have it running on https locally just for the development phase because it is a requirement. When I run my program without docker it opens successfully on https://127.0.0.1:8000. Which is the address the message says its currently running on. But when I use the same logic on my docker container after running docker-compose up the container compiles but I am unable to load the web page.

NOT NULL constraint failed on PUT request in Django
I'm new to Django and I'm having trouble handling form-data and raw data in PUT requests. I need to update records of a Person model via a PUT request. The Person model has several fields including fname, sname, age, and gender, all of which are required. I have a view to handle the PUT request, and I’m trying to handle both JSON and form-data formats in the request body. However, when I send a PUT request via Postman, I encounter the following error: Exception Type: IntegrityError Exception Value: NOT NULL constraint failed: api_person.fname To handle different request formats, I first attempt to parse the request body as JSON. If JSON parsing fails, I fall back to handling form-data. Here’s the relevant part of my view: ` try: # Attempt to parse request body as JSON data = json.loads(request.body) fname = data.get('fname') sname = data.get('sname') age = data.get('age') gender = data.get('gender') except json.JSONDecodeError: # Handle form-data if JSON parsing fails fname = request.POST.get('fname') sname = request.POST.get('sname') age = request.POST.get('age') gender = request.POST.get('gender') # Update person object with received data person.fname = fname person.sname = sname person.age = age person.gender = gender person.save() ` I expected this approach to handle both request … -

Best approach to object creation in the background without using a task queue system?
I have been thinking of the best approach to a record creation in the background without using django signals, or celery, etc. I do not want to use signals due to the fact that the sender Model would be called a very high number of times, as that table gets created/updated quite often. So I am looking to avoid this approach. My goal is to run a function that goes through some complex logic, ultimately ending in an EmailRecordTracker object creation in which I am doing some tracking to determine whether an email needs to be sent out or not at a later point in time. The function I need to create needs to get hit after a user submits a form and the form is fully saved. I was looking into asynchronous support possibly. https://docs.djangoproject.com/en/5.0/topics/async/ Workflow is pretty simple: User submits form, updates a form, etc. User is able to continue to navigate through app while my function to create an EmailTrackerRecord gets ran in the background. Any advice would be appreciated! -
