Django's AppConfig.ready() seems to be called once per thread in Apache wsgi
I have the following code in apps.py: class Pqawv1Config(AppConfig): # ... def ready(self): env_run_main=os.environ.get('RUN_MAIN') print('IS_PRODUCTION=%s, RUN_MAIN=%s' % (settings.IS_PRODUCTION, env_run_main)) if (not settings.IS_PRODUCTION) and (env_run_main != 'true'): print('Exiting because detected running in reloader.') return print('Starting up for PID=%s, argv=%s...' % (os.getpid(), sys.argv)) # Initialization of a singleton object from a C++ DLL # Raise an exception if this library was already initialized in this process In the evening I restarted the server and it printed the following in the log as expected: [Sun Sep 15 22:50:34.928549 2019] [wsgi:error] [pid 11792:tid 1176] Starting up for PID=11792, argv=['mod_wsgi']...\r However, in the morning I noticed that something strange has happened. It looks like Apache started a new thread for the web application: [Mon Sep 16 04:10:41.224464 2019] [wsgi:error] [pid 11792:tid 1160] Starting up for PID=11792, argv=['mod_wsgi']...\r And later: [Mon Sep 16 07:16:21.028429 2019] [mpm_winnt:error] [pid 11792:tid 2272] AH00326: Server ran out of threads to serve requests. Consider raising the ThreadsPerChild setting I think it's not the issue of calling AppConfig.ready() method twice because there were requests to the website in between and they were handled well. It rather looks like Django's AppConfig.ready() method is called once per worker thread of Apache process. Is this … -
How to display foreign key value instead of pk in django?
Here I am filtering staffs which has OnetoOne relation with the django User model.And the below code of function def filter_staff_users(request): also works fine as I wanted but the problem what I get is while displaying the organization name in message.I tried doing organization.name but it didn't worked. I got 'str' object has no attribute 'name' and when I tried converting int organization = int(request.GET.get('organization')) then it again throws 'int' object has no attribute 'name'.

API in django with response as data stream
I need to write an API in Django 2.2. It will be consumed by a google data studio connector. As a response I am fetching records from MariaDB. The size of the response causes the memory error on my production machine. So I am trying to stream it and this is what I did. Here is the code for iterator object. (Generation is model class) class Data(object): def __init__(self): self.paginator = Paginator(Generation.objects.get_queryset().order_by('id'), 100000) self.pagenum=1 def __next__(self): data="" if self.pagenum > self.paginator.num_pages: raise StopIteration if self.pagenum==1: data="[" data += serializers.serialize('json', self.paginator.get_page(self.pagenum))[1:-1] if self.paginator.num_pages == self.pagenum: data+="]" self.pagenum+=1 return data def __iter__(self): return self and here is the code for API response data = Data() response = StreamingHttpResponse(data,content_type="application/json") return response Problem: It seems connector does not wait for the entire stream to end and returns an invalid json error. -

Backup/restore of auth.permission table
I have a Django model schema that contains an external model pointing to the auth.group_permissions (and therefore auth.permission) table. As part of my system I run backups using ./manage.py dumpdata to dump to a JSON file - and restore using the corresponding ./manage.py loaddata. I've seen advice in the Django docs and the community (see this warning) suggests that backing up the auth.permission table is not advised - and so this table is not backed up (along with contenttypes and session). Of late I have been running into some issues - if I add a new table to the database then migrate, then new rows are added to the end of the auth_permission tables. However if I rebuild the database and run a migration from scratch, then the new rows are not always placed at the end of the table - they are sometimes getting added in a different order. This means that my backups - which do not include auth.permission - can sometimes point to incorrect row IDs, as the IDs will now be in a different order. This is obviously not ideal as it means my database can potentially not be correctly restored in case of catastrophic failure. … -

Unresolved import models Django + Docker
I have a few simple classes in my Django app that are not loading/importing properly. I know that the code works as I am Dockerizing over an existing app. I am fairly sure this is a similar issue to this but I do not know how to update this to use the Python inside my Docker container. I am following this guide (so all settings/configuration is the same). I have 2 classes: a custom user class and a Company model, and I am trying to add a foreign key on the user that links it to a particular Company. On the other side, I will have a many to many relationships (a company can have multiple users). from core.models import Company VS Code says "unresolved import" when I hover on core.models -

Form HTML, GET method. URL with multiple keywords

Support for partial file downloads using HTTP / REST
I have a client/server architecture in which the client needs to periodically download large files from the server. Let's say the client downloads 9Gb of a 10Gb file and then temporarily loses internet connection. When the client regains connection, I would like the client to be able to download the remaining 1Gb of the file rather than need to re-download everything from scratch. Is there any platform, libraries, frameworks, etc. which handles this? If not, does anyone have any ideas on how to best approach this problem?

How to temporarily disable a token in Django REST Framework
I have created a Django app using REST Framework and created user and token for authentication using the following commands: python manage.py createsuperuser --username Alex --email Alex@example.com python manage.py drf_create_token Alex I can view newly created user (Alex) and its token in Django admin panel and have no problem with authentication but I want to be able to sometimes temporarily disable a token (say for Alex for example) so that he could not authenticate.
