How to deal with django migration postgres deadlock?
So, I was deploying the django app to production and then the infamous postgres deadlock situation happened. This happens during the migration. Django version: 3.2 Postgres 13 Google cloud sql postgres. OperationalError deadlock detected DETAIL: Process 112506 waits for AccessExclusiveLock on relation 29425 of database 27145; blocked by process 112926. Process 112926 waits for RowShareLock on relation 29381 of database 27145; blocked by process 112506. HINT: See server log for query details. I ran this query to get the process info: SELECT 29425::regclass,29381::regclass from pg_locks; and result: regclass | regclass "custom_requestlog" "auth_user" "custom_requestlog" "auth_user" I am not sure how to proceed ahead, as the pgaudit has been enabled but it doesnt show anything and also the query insights is not that helpful. Attached is image of query insights. Any help would be helpful please! -

Django model location from a view

About shipping structure in django ecommerce
I wanted to ask what kind of structure should I use for my shipping fee. I wanted to fix my shipping fee to a certain number may be 30$, but then when I want to change the number I can do that in the admin panel, and also for a certain threshold I want to give my customers free shipping. So what do you suggest friends? Should I have a separate class for shipping? or can I finish it in my Order class by adding one field? -

Calling FileField objects in template renders incorrect path
I've implemented a FileField model in my project. I can successfully upload svg files and they save to the desired location. Within my project, I make heavy use of user uploaded images (JPGs) and they save to the correct location and I can display them in my templates with no issue. However, when I upload an svg to the FileField and then attempt to display it within the template, the link is broken. The problem is that the correct file path isn't being set within the html Template <img src="{{ account.image }}" /> It should point to the following path: localhost:8000/media/Users/jimmy/file.svg But it resolves as the following, which is incorrrect: localhost:8000/profile/settingspage1/Users/jimmy/file.svg Essentially, I've I manually append '/media' to the filepath within the template, it works, but I shouldn't have to do this. The filepath should resolve correct. <img src="/media/{{ account.image }}" /> Any thoughts on what setting could be preventing only filefields from resolving to the correct path within my media folder? Thanks! -
django removes "is_staff" permission if I try to login
I have a pretty strange situation within my django project. I have a LoginForm where a user can log into the website. I am using django 3.2.12 with some other libraries like django-crispy-forms and so on. I implemented django-crowd-auth so that users can access the page with crowd. I made the neccessary configurations in settings.py and the app is running without any issues. Afterwards I gave my existing user is_staff and is_superuser permissions to access the django administration. I did it like this: python manage.py shell >>> from django.contrib.auth.models import User >>> user = User.objects.get(username="<myuser>") >>> user.is_staff = True >>> user.is_superuser = True >>> print(user.is_staff) True >>> print(user.is_superuser) True >>> save() After that I restart my django app the following way: sudo <path_to_conda_env_python>/python manage.py runsslserver --certificate <crt-file> --key <pem-file> 0.0.0.0:88 If I try to log into the django administration panel with the user which I just gave the permissions I get the error "Please enter the correct username and password for a staff account. Note that both fields may be case-senitive" Returning to the django shell gives me this output python manage.py shell >>> from django.contrib.auth.models import User >>> user = User.objects.get(username="<myuser>") >>> print(user.is_staff) False >>> print(user.is_superuser) False It seems … -
Getting Bad Gateway and Connection reset by peer using asyncio + aiohttp
Is there some async expert with sharp eyes around? I am using asyncio (Python 3.9) with aiohttp (v3.8.1) to fetch multiple urls asynchronously through a proxy, but this implementation seems to fail pretty often throwing reset by peer and Bad Gateway errors. The same proxy works well using Scrapy spiders so there must be something wrong with my async implementation. My code: from asgiref.sync import async_to_sync import asyncio import aiohttp async def async_fetch_url(session, url: str, method: str = "get"): async with getattr(session, method)(url, proxy="https://someproxy.com/") as response: return await response.json(content_type=None) async def my_async_fetch(urls: list, method: str = "get"): async with aiohttp.ClientSession(connector=aiohttp.TCPConnector(force_close=True)) as session: return await asyncio.gather(*[async_fetch_url(session, url, method=method) for url in urls]) def my_sync_func(): urls = [ 'https://somesite.com/1', 'https://somesite.com/2' ] result = async_to_sync(my_async_fetch)(urls) Error logs: [2022-04-28 21:47:28,576: ERROR/MainProcess] ???[???]: [Errno 104] Connection reset by peer [2022-04-28 21:47:28,576: ERROR/MainProcess] ???[???]: Traceback (most recent call last): File "/app/cubist_backend/helpers.py", line 176, in async_fetch_url async with getattr(session, method)(url, **kwargs) as response: File "/usr/local/lib/python3.9/site-packages/aiohttp/client.py", line 1138, in __aenter__ self._resp = await self._coro File "/usr/local/lib/python3.9/site-packages/aiohttp/client.py", line 535, in _request conn = await self._connector.connect( File "/usr/local/lib/python3.9/site-packages/aiohttp/connector.py", line 542, in connect proto = await self._create_connection(req, traces, timeout) File "/usr/local/lib/python3.9/site-packages/aiohttp/connector.py", line 905, in _create_connection _, proto = await self._create_proxy_connection(req, traces, … -

How to use multiple databases in Django with an empty 'default'?
I'm trying to make a multiple database project in Django. But I'm having problems to properly migrate my models to the appropriate database. I'm using the 'Writing your first Django app' tutorial as a starting point; so ... I've written the following database routers; this one for 'polls' app: class PollsRouter: route_app_labels = {'polls'} def db_for_read(self, model, **hint): if model._meta.app_label == 'polls': return 'Polls' return None def db_for_rite(self, model, **hint): if model._meta.app_label == 'polls': return 'Polls' return None def allow_relation(self, obj1, obj2, **hint): if ( obj1._meta.app_label == 'polls' or obj2._meta.app_label == 'polls' ): return True return None def allow_migrates(self, db, app_label, model_name=None, **hints): if app_label == 'polls': return db == 'Polls' return None Also the router class for 'devices' app: class DevicesRouter: route_app_labels = {'devices'} def db_for_read(self, model, **hint): if model._meta.app_label == 'devices': return 'CTS_ER_BD' return None def db_for_rite(self, model, **hint): if model._meta.app_label == 'devices': return 'CTS_ER_BD' return None def allow_relation(self, obj1, obj2, **hint): if ( obj1._meta.app_label == 'devices' or obj2._meta.app_label == 'devices' ): return True return None def allow_migrates(self, db, app_label, model_name=None, **hints): if app_label == 'devices': return db == 'CTS_ER_BD' return None And finally, the router class for 'auth_user' database (for native Django apps) class Auth_userRouter: route_app_labels = …
