Is there a way in Django to specify a starting/first test?
My tests take a long time to run, and many times fixing one test often fixes multiple tests, so I often use --failfast to fix tests one by one in the order in which they error out. I fix a test, then rerun to find the next failure that wasn't due to the same root cause as the one I just fixed. The problem is that the tests take a long time to run and I have to wait through all the tests that I already know will pass. *I'm aware that code changes to fix one test could break a previously run/successful test, but I'd prefer to handle that in a second run. What I would like to do is specify a "starting test" so that I only run the tests from the previous failure forward. I don't see a way to do that using python manage.py test. Is there a trick to get it to not test previously run tests and just pick up where it left off? -
Django dev server does not start if noreload is not set
I'm encountering an issue when attempting to start the Django development server with runserver_plus from django-extensions When I initiate it with the following command: python backoffice/manage.py runserver_plus 0.0.0.0:8000 --noreload It starts successfully without any problems. However, if I use the following command instead python backoffice/manage.py runserver_plus 0.0.0.0:8000 Notice that if I not pass the --noreload flag, it returns the following error: backoffice/manage.py: [Errno 2] No such file or directory The command is being executed in the same place so it does not make sense why is not finding the manage file. Why does it only work when I include --noreload? Is there a way to make it work? I would like to use the reload capability to save time in development process. Thank you! -
Why am I getting Post method error while submitting form in Django?
This is the error which i m getting when trying to click on the submit button: Page not found (404) Request Method: POST Request URL: http://127.0.0.1:8000/contact/ Using the URLconf defined in career.urls, Django tried these URL patterns, in this order: admin/ myapp/ signup /contact ^media/(?P\<path\>.\*)$ The current path, contact/, didn’t match any of these.

Problem Configuring Static in OpenLiteSpeed with Django Project (www.menuweb.cl)
The problem. traditional-italian-food-world-tourism-day.jpg:1 - Failed to load resource: the server responded with a status of 404 /#:1 - Refused to apply style from 'https://menuweb.cl/python/static/main/home.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

I can't install ebcli with Python 3.11.4 | AttributeError: cython_sources | Getting requirements to build wheel did not run successfully
When I try to install ebcli using Python 3.11.4 (inside a venv, as per the official instructions)I get an error and I just can't get around it. If I try to install ebcli using Python 3.8.10(again inside a venv, but this time the 3.8.10 version), it does work.

Add prefix to router while still showing it in API root view

Django different 404 Errors on Production
I have product pages and tag pages on my website. For the product query, I use the code: product = get_object_or_404(Product, slug=slug), and for the Tag query, I use: tag = get_object_or_404(Tag, slug=slug). When running my code on my local machine with DEBUG set to True, I encounter a Django error page with a 404 status code. However, in my production environment, I experience different behaviors for the two types of pages. For tag pages, like https://my.domain/tag/abrakadabra/, I correctly receive a 404 error page. However, for product pages, like https://my.domain/product/abrakadabra/, I encounter an internal server error instead of the expected 404 error page. Interestingly, when I set DEBUG to True on my production server, I do receive the correct 404 Django error page for both tag and product pages. -

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! -

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. -

Django on_delete for Model with custom delete function
I have the following models: class Concert(models.Model): name = models.CharField(max_length=255) is_deleted = models.BoolField(default=False) def delete(self): self.is_deleted = True self.save() class Ticket(models.Model): concert = models.ForeignKey(Concert, on_delete=models.CASCADE) is_deleted = models.BoolField(default=False) def delete(self): self.is_deleted = True self.save() I noticed when I call delete on Concert, it doesn't call delete on Ticket. 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 = { …
