Python Sort by DateTime using list.sort()
I am trying to sort a list of comments by date. They have a date field that contains a datetime object(?) auto-created by Django. Because of how multiple comment-models have been combined in the list, I cannot use Django's built-in .order_by() sorter. Right now I am testing with just 3 comments, but they are already out of order when I sort them. The three datetimes as strings: 2020-08-21 16:17:40.690851+00:00 2020-08-21 15:04:32.315342+00:00 2020-08-21 12:10:21.720688+00:00 The comment models: class MealComment(models.Model): date = models.DateTimeField(auto_now_add=True) class Meta: ordering = ('-date',) class SubComment(models.Model): date = models.DateTimeField(auto_now_add=True) class Meta: ordering = ('-date',) How the list is created and sorted: mealcomments = user.mealcomment.all() subcomments = user.subcomment.all() if mealcomments and subcomments: comments = list() for comment in list(mealcomments): comments.append(comment) for comment in list(subcomments): comments.append(comment) comments.sort(key=lambda a: a.date) The comments are currently sorting into this order (which looks unsorted but is definitely going through the sort function): Aug. 21, 2020, 4:17 p.m. Aug. 21, 2020, 3:04 p.m. Aug. 21, 2020, 12:10 p.m. Why are they not sorting into any particular order, and how can I sort them correctly? -
Django manage.py shell save() doesn't save to postgresql database
I am new to Django. Testing out a simple application (test_cedar_app) with a PostgreSQL database called test_cedar. I have the following model for the application: class answer_key(models.Model): answer_text = models.CharField(max_length=20) def __str__(self): return self.answer_text I made a migration and applied it, and verified in my psql command-line client with \dt that the schema was created properly. I opened the Django command-line client using python manage.py shell and entered the following: ak_1 = answer_key(answer_text='Yes') ak_2 = answer_key(answer_text='No') ak_1.save() ak_2.save() These appeared to save, as the following revealed that the full query set for answer_key contains ak_1 and ak_2: from test_cedar_app.models import answer_key answer_key.objects.all() returned <QuerySet [<answer_key: Yes>, <answer_key: No>]> However, if I then enter the psql command-line (psql test_cedar), and enter the following: SELECT * FROM test_cedar_app_answer_key Nothing appears. Why do my changes not propagate to the database as it appears within the psql command-line tool? -
Issues with Secret Key when deploying Django App to Heroku
I keep getting django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty. when trying to deploy my django app to heroku. I'm using python-dotenv and my settings.py file looks like this: import os from dotenv import load_dotenv load_dotenv() SECRET_KEY = os.getenv("DJANGO_SECRET_KEY") And the .env file (which is in my .gitignore file has the DJANGO SECRET KEY stored: export DJANGO_SECRET_KEY=mykeyhere I'm using pipenv if it helps - everything is working fine locally, but heroku doesn't seem to pick up on the variable. Any thoughts? (I also tried adding the secret key as a config variable on the heroku dashboard without success) -

Why is django allauth redirecting to /accounts/login/?=next/MY_PAGE instead of logging in?
I am attempting to handle user authentication on a site using Django allauth. However, upon entering a username and password and clicking "log in" on my site, I am redirected to /accounts/login/?=next/MY_PAGE and the login page is simply reloaded. I have seen a number of similar questions, and I know that sometimes people run into issues with this when authenticating with socials, but I am not using any form of social authentication. I already have the LOGIN_REDIRECT_URL set to the desired page's URL, and I attempted to create an adapter as follows: class AccountAdapter(DefaultAccountAdapter): def is_open_for_signup(self, request): return getattr(settings, "ACCOUNT_ALLOW_REGISTRATION", True) def get_login_redirect_url(self, request): path = "/news/" return path where get_login_redirect_url should direct the application to the desired page. I have read in other posts that the fact that the next page (in this case "News") isn't being loaded means that allauth is not actually logging me in, and that's why I end up just getting the login page reloaded. Would anyone be able to point me in the right direction? Thanks! -

Creating multiple objects with bulk_create() or models.Manager in Django
Let's say I have 2 sports modalities in the Athlete class, each with 7 categories and in each category there are 20 athletes. My goal is to fill out a form with training information about Tactic or Technique or Conditioning, of a specific modality/category, that can populate the 20 athletes at once. I'm only using djando Admin, so I don't have views.py Many websites indicate using bulk_create(), which receives a list as input, to create several objects. Another option seems to be to overwrite the object manager with models.Manager. I would like to know if any of these options apply to buy problem and how I could use them. I hope the information has been clear.

Django multiple requests made when passing variable

I deployed my Django project that uses Apache and MySQL. all apps features work fine, but in an application's views.py, when I try to access it, it raises this error. UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 9735: ordinal not in range(128) it works fine in localhost I searched a lot but none of them works for me. The views.py of the app has many queries (for calculating), annotate and aggregate also Case(When())? this is my error.log [Fri Aug 21 14:30:46.907352 2020] [wsgi:error] [pid 20969:tid 140683116439296] [remote 95.159.84.254:12151] File "/var/www/projectname/venv/lib/python3.6/site-packages/django/views/debug.py", line 94, in technical_500_response [Fri Aug 21 14:30:46.907356 2020] [wsgi:error] [pid 20969:tid 140683116439296] [remote 95.159.84.254:12151] html = reporter.get_traceback_html() [Fri Aug 21 14:30:46.907362 2020] [wsgi:error] [pid 20969:tid 140683116439296] [remote 95.159.84.254:12151] File "/var/www/projectname/venv/lib/python3.6/site-packages/django/views/debug.py", line 332, in get_traceback_html [Fri Aug 21 14:30:46.907379 2020] [wsgi:error] [pid 20969:tid 140683116439296] [remote 95.159.84.254:12151] t = DEBUG_ENGINE.from_string(fh.read()) [Fri Aug 21 14:30:46.907387 2020] [wsgi:error] [pid 20969:tid 140683116439296] [remote 95.159.84.254:12151] File "/usr/lib/python3.6/encodings/ascii.py", line 26, in decode [Fri Aug 21 14:30:46.907391 2020] [wsgi:error] [pid 20969:tid 140683116439296] [remote 95.159.84.254:12151] return codecs.ascii_decode(input, self.errors)[0] [Fri Aug 21 14:30:46.907402 2020] [wsgi:error] [pid 20969:tid 140683116439296] [remote 95.159.84.254:12151] UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 9735: ordinal not in range(128) [Fri Aug 21 … -
