Does subprocess.Popen.wait deadlock when using file type for stdout?
Any help is appreciated. I have a custom Django command and a method like the one below: def read_status_to_list(self) -> List[str]: with open('git.txt', 'w+') as temp: status = subprocess.Popen(['git', 'status'], stdout=temp) status.wait() statuses = [line.split()[-1] for line in temp.readlines() if 'modified:' in line ] # remove file when done if os.path.isfile('git.txt'): os.remove('git.txt') return statuses However, statuses is always empty even when git status produces a number of modified modules not added yet. I noticed a warning in the wait method: Warning: This will deadlock when using stdout=PIPE and/or stderr=PIPE and the child process generates enough output to a pipe such that it blocks waiting for the OS pipe buffer to accept more data. Use communicate() to avoid that. Is this warning related to the problem, and how can I successfully complete this task using subprocess? Thank you. -

how to filter the data from django database for a week?

Celery not running new task
I've readded an old Celery task to my Django app running on Heroku, but it's not being run by the worker. The task appears in the tasks when the worker starts, and I can see the scheduler sending it to the worker. However, it is never received by the worker. What can I do to troubleshoot this issue? Other tasks added are running fine and it runs fine on the staging server which is another instance on Heroku. I've tried restarting all the dynos and changing the name of the task and repushing it but that hasn't worked. -

To overcome this issue, I added the following line to the settings.py : SESSION_COOKIE_AGE = 604800 # one week But a few hours leading to timeout means that this line has had no effect. I need CSRF tokens longevity be increased to a few days rather than minutes. How to achieve this? -

Arabic translations not displayed correctly in Django/Celery notification system
I'm currently working on a Django application that includes various functionalities, including notification delivery, in multiple languages. While most of the application works well with Arabic and other languages, I'm facing an issue with Arabic translations in certain parts of the application, including notifications. The Arabic translations are not being displayed correctly, while translations in other languages, such as English and French, work without any issues. Here are the details of my setup: The application uses Django and Celery for task management and background processing. I have added Arabic translations for different text elements in the respective translation files. The Arabic translations work fine in most parts of the application, including UI labels and content. However, when it comes to notifications, specifically in Arabic, the translations are not displayed correctly. Other functionalities, such as database operations, user management, and data processing, work as expected with the Arabic translations.

How to connect 2 views in the same Django app? (ListView and EditView)
I have 2 apps called Prospecto(which means Prospect) and Cliente(which means Customer). When you see a register in EditView and click on its checkbox, you can indicate whether the register is still in Prospecto or Cliente If you don't click on the checkbox, that record is still in the Propsecto If you click the checkbox, that record becomes a Cliente and is no longer a Prospect In the code I did, when I clicked the checkbox, it turns into record in Customer(that's ok), but I can't delete it from Prospecto(in ProspectoListView). **views.py class ProspectoListView(ListView): model = Prospecto template_name = 'prospectos.html' context_object_name = 'prospectos' def get_queryset(self): queryset = super().get_queryset() fecha_inicio = self.request.GET.get('fecha_inicio') fecha_fin = self.request.GET.get('fecha_fin') if fecha_inicio and fecha_fin: queryset = queryset.filter(fecha__range=[fecha_inicio, fecha_fin]) elif fecha_inicio: queryset = queryset.filter(fecha__gte=fecha_inicio) elif fecha_fin: queryset = queryset.filter(fecha__lte=fecha_fin) return queryset def ProspectoEditar(request, pk): prospecto = get_object_or_404(Prospecto, pk=pk) if request.method == 'POST': form = ProspectoForm(request.POST, instance=prospecto) if 'es_cliente' in request.POST: cliente = Cliente(nombre=prospecto.nombre) cliente.save() prospecto.es_cliente = True prospecto.delete() if form.is_valid(): form.save() return redirect('prospectos:prospectos_list') else: form = ProspectoForm(instance=prospecto) return render(request, 'prospectos-editar.html', {'form': form}) I try with this solution, adding delete() but it doesn't work class ProspectoListView(ListView): model = Prospecto template_name = 'prospectos.html' context_object_name = 'prospectos' def get_queryset(self): fecha_inicio … -
