Dealing with multiple databases in Django with and without timezones
I'm in the situation where I use django (2.0.7) to deal with multiples databases: database_A: without timezone; database_B: with timezone 'Europe/Paris'; settings.py USE_TZ = True TIME_ZONE = 'Europe/Paris' DATABASES = { 'database_A': { 'NAME': ... 'PASSWORD': ... etc. 'TIME_ZONE': None, # still raise RuntimeWarning; received a naive datetime while time zone support is active. }, 'database_B': { 'NAME': ..., etc. } on models of database A class Something(models.Model): date_creation = models.DateTimeField() def save(self, *args, **kwargs): if self._state.adding is True: self.date_creation = timezone.datetime.now() # naive print("BEFORE SAVE") print(self.date_creation) super(Something, self).save(*args, **kwargs) print("AFTER SAVE") print(self.date_creation) print("AFTER REFRESH") self.refresh_from_db() print(self.date_creation) I get the following result BEFORE SAVE 2019-11-04 11:44:35.233876 AFTER SAVE 2019-11-04 11:44:35.233929 AFTER REFRESH 2019-11-04 10:44:35.23392 # 10:44:35 , what's wrong ô_O ? I have the same 1 hour difference between Europe/Paris and UTC. import pytz from datetime import datetime datetime.now(tz=pytz.timezone('Europe/Paris')), timezone.now() (datetime.datetime(2019, 11, 4, 12, 10, 55, 320028, tzinfo=<DstTzInfo 'Europe/Paris' CET+1:00:00 STD>), datetime.datetime(2019, 11, 4, 11, 10, 55, 320077, tzinfo=<UTC>)) So, I think PostgreSQL is using UTC to save my naive datetime considered as timezone aware datetime ? In database I have the following time \d something_table date_creation | timestamp without time zone | non NULL Par defaut, now() SELECT NOW(); … -
Is there any simplest way to run number of python request asynchronously?
There is an API localhost:8000/api/postdatetime/, which is responsible for changing the online status of the driver. Every time a driver hits the API and if the response sent back then the driver status will be online otherwise the driver status will be offline. Drivers need to give the response within every 10 seconds. If there is no response from the driver then he/she will be marked as offline automatically. Currently what I am doing is getting all the logged in drivers and hitting the above-mentioned API one driver at a time. For the simulation purpose, I populated thousands of drivers. To maintain the online-offline of thousands of drivers using my approach will leave almost many drivers offline. The code for my approach is as described below: online-offline.py import requests import random import math from rest_framework.authtoken.models import Token from ** import get_logged_in_driver_ids from ** import Driver def post_date_time(): url = 'localhost:8000/api/postdatetime/' while True: # getting all logged in driver ids logged_in_driver_ids = get_logged_in_driver_ids() # filtering the driver who are logged in and storing their user id in the driver_query variable driver_query = Driver.objects.only('id', 'user_id').filter(id__in=logged_in_driver_ids).values('user_id') # storing the user id of driver in list driver_user_ids = [driver['user_id'] for driver in driver_query] # … -
Azure Functions Django ModuleNotFoundError
I have been trying to run Django on Azure Function as mentioned in the tutorial below Running serverless Django apps with Functions I am trying to use the following module as mentioned https://github.com/carltongibson/azure-functions-wsgi-adapter The library above does not look maintained, still, the approach is simple enough and should work. I am able to get the code in the tutorial running, but my code is not working. The only difference I see is in the directory stucture(my code and Django by default has one more level in the directory structure). My directory structure is: Running the above gives me the following error on Azure: Exception: ModuleNotFoundError: No module named 'notifications' Stack: File "/azure-functions-host/workers/python/3.6/LINUX/X64/azure_functions_worker/dispatcher.py", line 242, in _handle__function_load_request func_request.metadata.entry_point) File "/azure-functions-host/workers/python/3.6/LINUX/X64/azure_functions_worker/loader.py", line 66, in load_function mod = importlib.import_module(fullmodname) File "/usr/local/lib/python3.6/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "/home/site/wwwroot/serverless/__init__.py", line 14, in <module> from notifications.notifications.wsgi import application By default Django project parent directory does not have an __init__.py, I have added it so that import works.

How to use class based views with more than one model?

Django + JQuery - Iterate over table rows updating each row with json data

Django Rest Framework: insert list using ModelViewSet

Regular expression to match phrases with plus sign
Was wondering what is the best way to match "clear 18+ from your history" from "clear 18+ from your history? blah blah blah" is? Using Python.

If there is a special character like the plus sign, it won't work. Thanks in advance. -

However if I simply upload a pdf file, it gets successfully uploaded but when I upload after encrypting the file, only first 4096 bytes are stored and rest are not there. When I tried adding the same encrypted file using ipfs add command on the terminal, the file is successfully uploaded. Here is the code for uploading an encrypted file: file_ = open(os.path.join(settings.ENCRYPTION_ROOT,str(paper)+'.encrypted'),'rb') s_file = File(file_) store = Request.objects.get(tusername=request.user.username) store.paper.save(str(paper)+'.encrypted',s_file,save=True) I have searched everywhere but still didn't get any help in this regard.
