Django stuck after doing code change (hot reload not working)
I upgraded my Django version from 3.2.15 to 4.2.1 and also my Python version from 3.7.13 to 3.11.0 and the hot reload of my Django project stopped working. The server starts as expected with the pipenv run python src/manage.py runserver {host}:{port} command, but when I do a code change and save the file the server gets stuck saying: [INFO] [django]: /my-route/my-file.py changed, reloading And I have to kill the process on the console and start it again to make it work. When I had my old dependencies, after saving a file the server just reloaded and it showed the changes. I tried to set the verbosity to 3, but I can't get any information explaining the error and I don't know how to debug it. It looks like it uses StatReloader to detect this file changes: [INFO] [django]: Watching for file changes with StatReloader gets printed before starting the server. I would really appreciate it if you can give me some help or direction to follow about this topic. Thanks in advance! -

Django Email Incorrect Accent Characters
I'm facing an issue with sending emails using Django where the accent characters are not rendered correctly. ** Problem:** When I send an email containing accent characters (e.g., é, à, ü), they SOMETIMES appear incorrectly in the received email. Instead of the correct character, I see a different symbol/letter. I'm using Django, in particular Celery do send the emails. Here is my code: Template: {% extends 'general/mail_header_and_footer.html' %} {% load settings %} {% load i18n %} {% block title %}{{ title }}{% endblock %} {% block description %} <p>Ciao {{ customer_name }},</p> <p> The booking for {{ experience_variant_name }} is not available for {{ starting_time|time:'H:i' }} of {% language 'it' %} {{ starting_date|date:'l, d F Y' }} {% endlanguage %}. </p> Python: email = EmailMessage( subject=subject, body=message, from_email=DEFAULT_FROM_EMAIL, to=[booking.customer_email], bcc=MANAGERS_EMAILS, headers={"Content-Type": "text/html; charset=UTF-8"}, ) email.content_subtype = "html" email.send() settings.py: EMAIL_CHARSET = "utf-8" And I'm using sendgrid. -
i have some questions about full-stack with django
I learned Python and I plan to become a web developer, but I don't know if it is better to become full stack or back end. I know Django is good for Python. Is it good to learn the backend first? This is the road map I decided to follow, do you approve? https://github.com/HHHMHA/django-roadmap -
Issue with accessing form.cleaned_data in Django view function
I'm encountering an unexpected issue while working on a Django project involving a registration form. I have two code snippets that are functionally similar, but I'm getting different outcomes regarding the access to form.cleaned_data. I'm hoping someone can help me figure out what might be causing this discrepancy. Code Snippet 1: def signup(req): if req.method == 'POST': form = RegisterForm(req.POST) if form.is_valid(): messages.success(req, 'Account Created successfully') form.save() print(form.cleaned_data) return render(req, 'signup.html', {'form': form}) else: form = RegisterForm() return render(req, 'signup.html', {'form': form}) Code Snippet 2: def signup(req): if req.method == 'POST': form = RegisterForm(req.POST) if form.is_valid(): messages.success(req, 'Account Created successfully') form.save() print(form.cleaned_data) return render(req, 'signup.html', {'form': form}) form = RegisterForm() return render(req, 'signup.html', {'form': form}) In both snippets, the form is submitted and processed similarly. However, when I use the first snippet, I can successfully access form.cleaned_data and print it after a successful form submission. But when I use the second snippet, form.cleaned_data seems to be unavailable, and the printed output is empty. I have double-checked the code for any typos or missed details, but both snippets are practically identical. I'm quite puzzled as to why this difference in behavior is occurring. -

Why in Django many-to-many relation shows wrong data in the admin panel
I'm trying to implement the many-to-many relation to support in the user model these features: user followers (persons who follows the user) user following (persons the user follows) To achieve that I'm using double relation on the same model because followers/following are the same User models. Basically it works hoverwer I'm facing a weird behavior in the Django admin panel. When I add some user to other user to the following list (in the shell everything ok), the Django admin panel shows that user in the followers list but he should be in the following list. I can't understand why it happens. Many thanks for any help!

Django on_delete for Model with custom delete function

This is expected behavior, right? Is there any way to trigger CASCADE even in the case of this custom delete function? -
Google Ads API & Python - How to get all accounts (name + ID) that a user has access
I'm trying to get the account name and ID of all the accounts that the logged user has access to. I've managed to get the IDs using the code on https://developers.google.com/google-ads/api/docs/account-management/listing-accounts?hl=es-419. But I need the names too and apparently you have to make one API call for each ID to get their account names or any other info. I've tried with the following Python (Django) code, but it's not working (it probably could be improved a lot and maybe has mistakes, I'm a Python beginner): def one(request): client = credenciales(request) ga_service = client.get_service("GoogleAdsService") # Get customer resource names from the original code customer_service = client.get_service("CustomerService") accessible_customers = customer_service.list_accessible_customers() customer_resource_names = accessible_customers.resource_names # Prepare a list to store customer data list_clients = [] # Iterate through each customer resource name for resource_name in customer_resource_names: # Extract the customer ID from the resource name custom_id = resource_name.split('/')[-1] # Create a query using the customer_id query = f''' SELECT customer_client.descriptive_name, customer_client.id, customer_client.status FROM customer_client ''' stream = ga_service.search_stream(customer_id=custom_id, query=query) for batch in stream: for row in batch.results: data_clients = {} data_clients["descriptive_name"] = row.customer_client.descriptive_name data_clients["id"] = row.customer_client.id data_clients["status"] = row.customer_client.status list_clients.append(data_clients) # Pass the list of customer data to the template context = { … -
django object.id does not work when passed in an url in html
I have just started learning Django and I cannot figure out why my player.id kills the page when I try to pass it in an url, while it does work as a variable (see both in the code below.)

Is there a way to make a https post with only port 80 in nginx config file?
So, I a have Django app which needs to send data to an API. I am using request to send the data. First, it was warning me that -in short- I am not using SSL for sending the JSON data. To solve this I added "verify=PATH TO THE CERT FILE" requests.post(url, json=payload, verify='\fullChainCert.crt') After this I got 200, so I was happy. Question is, will it work like this on server? Port 443 is open on server, but only 80 in nginx config file. -

Moving from Django signals to save override: How to translate the "created" parameter of a Django post_save signal for a save method override
I have made some bad decisions earlier regarding how I handle post_save events on a Django model and I am currently looking into changing my approach. Let's begin by making my example. Here is my model. class MyModel(models.Model): #... all my model creation and logic are here def do_something(self): # Actually do something, for the sake of simplifying the example, just write pass pass Now, what I am using is a receiver function like this one. It works, but for many reasons that are mine, I want to stop using signal in this case. @receiver(post_save, sender=MyModel) def foo(sender, instance, created, **kwargs): if created: instance.do_something() I imagine I could override the MyModel.save method, something like this: class MyModel(models.Model): #... def save(self): super().save() if created: # It is this line that I need to figure how to do. self.do_something() By what should I replace the if created: of my receiver function if I want to override the save() method? Or do you have something else to recommend? I would also be curious if it is the same thing for pre_save signals. -
