What are the next steps after I made a functional Django web app in my personal laptop?
I'm new to programming. What are the general steps a web developer takes after he made a web app or static website using Django in a personal computer? I'm not asking for specifics cause probably is too long, but more general stuff that I can later research myself online. For example: Make a web app in Django. Buy a physical server. Install apache. Buy a domain name or hosting. Bear with me, I'm a noob so probably I listed nonsense, but just trying to ask how its supposed to ask here. For example, if I wanted to make a cake: Get a recipe. Gather the materials/ingredients. Mix ingredients. Place it in oven to bake. Take it out let it cool. Serve to people. I just need the correct path to take, not much the specifics on how to accomplish each path "station". Hope I asked well, thanks guys. -

Image upload error from React Form into Django ImageField
I want to update ImageField in my Django model and i am using axios PATCH method for it. Image comes from my Ant Design Form and i save it in my state. Why i cant update my image file as so?

Django application: UserPassesTestMixin to verify user is the author of posts before allowing access to view?
The goal of my application is to allow users to create posts for their own private account viewing. I'm using a class based view to show the current logged in user their posts. In order to prevent users from being able to see other user's posts, I have a UserPassesTestMixin test_func that iterates through the query set and checks to make sure they are the author of those posts. The problem that I'm having is when there are no posts to display, I receive a 404 error code stating that there is nothing matching the query. I want it to still display the page even when there are no posts available. When I only use the get_queryset function, it works and displays my template without posts, but without having the UserPassesTestMixin and test_func, a user could enter another person's username into the URL and be able to view the other person's account/posts. Here is the code for this class based view in my views.py file: class UserSessionListView(LoginRequiredMixin, UserPassesTestMixin, ListView): model = session template_name = 'programmerjournal/user_sessions.html' context_object_name = 'sessions' paginate_by = 24 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) return session.objects.filter(author=user).order_by('-date_added') def test_func(self): user = get_object_or_404(User, username=self.kwargs.get('username')) posts = get_list_or_404(session, author=user) for … -

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! -

AttributeError: module 'MySQLdb.constants.FIELD_TYPE' has no attribute 'JSON' while migrating in Django
I do not know in what way solve this error. Any hints? I have simple Django projects and receive this error when try to do python3 manage.py migrate. This is related to any programming error in app or this is possible there is any error related to installation of mysql and completeness of its packages? Maybe there is any error in manage.py file? Or maybe this is case in not compatible version of Django and mysql?

Django multiple requests made when passing variable
I am trying to create an update form from an inlineformset and include a button that checks the next record. Here is my view: def update_challenges(request, challenge_id): challenge_ids = list(ChallengeModel.objects.values_list('id', flat=True)) next_index = challenge_ids.index(int(challenge_id)) + 1 next_challenge_id = challenge_ids[next_index] challenge = ChallengeModel.objects.get(pk=challenge_id) RoundFormset = inlineformset_factory(ChallengeModel, Round, fields=('index','description'),extra=0, widgets = { 'description': TextInput(), 'index':NumberInput() }) VarFormset = inlineformset_factory(ChallengeModel, Var, fields=('name',),extra=0) if request.method == 'POST': round_formset = RoundFormset(request.POST, instance=challenge) var_formset = VarFormset(request.POST, instance=challenge) if round_formset.is_valid() and var_formset.is_valid(): round_formset.save() var_formset.save() return redirect('update_challenges', challenge_id=challenge.id) round_formset = RoundFormset(instance=challenge) var_formset = VarFormset(instance=challenge) return render(request, 'drinking_game/update_challenges.html', {'round_formset':round_formset, 'var_formset':var_formset, 'challenge_id':challenge_id, 'next_challenge_id':next_challenge_id}) And here is the button I use for going to the next challenge:<button class="home-play-btn" onclick="location.href='{% url 'update_challenges' next_challenge_id %}'">Next challenge</button> However, when I check the output of my console, a new get request to the old url gets made right after the new request. This looks the following: [21/Aug/2020 15:29:23] "GET /update_challenges/221/ HTTP/1.1" 200 6373 [21/Aug/2020 15:29:23] "GET /update_challenges/220/ HTTP/1.1" 200 6339 The url path for this view is path('update_challenges/<challenge_id>/', views.update_challenges, name='update_challenges') What goes wrong that the old request is also made? Thanks.
