pycharm cookiecutter docker django project Django support not working
I have a project that I have created with cookieecutter django (docker). I'm setting up Interpreter via docker-compose via Pycharm. Interpreter works fine. Django support is not working even though I have Django Support enabled. However, when I use Interpreter in another project in this project, django support works.But I can't use it because it's a different Interpreter for different project. even the .filter() function from one of my models does not come as a suggestion enter image description here enter image description here When I use the docker compose Interpreter of another project for this project in pycharm, django support works. But I couldn't understand, I created the project with cookiecutter, I didn't change anything. Why django support is not working. -

django not receiving correct response? in front
overview When you press the 'like!' button, there is processing to feed back to the front screen via server processing (create or delete). No error when creating. Feedback is fine too. I get an error when deleting and the feedback doesn't work. The content of the error seems to be that json cannot be received correctly. The creation process and deletion process are almost the same, and the records are also registered and deleted in the database. So the processing is exactly the same. What's causing this? It seems so simple, but... detail # model class Articles(models.Model): title = models.CharField(max_length=200) note = models.TextField() user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) objects = ArticlesQuerySet.as_manager() @staticmethod def with_state(user_id: int) -> QuerySet: return Articles.objects.annotate( likes_cnt=Count('likes'), liked_by_me=Case( When(id__in=Likes.objects.filter(user_id=user_id).values('articles_id'), then=1), default=0, output_field=IntegerField() ) ) class Likes(models.Model): articles = models.ForeignKey('Articles', on_delete=models.CASCADE) user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) class Meta: constraints = [ models.UniqueConstraint( fields=['articles_id', 'user_id'], name='articles_user_unique' ) ] # views.py class LikesCreateView(LoginRequiredMixin, CreateView): def post(self, request, *args, **kwargs): return_value = None try: Likes.objects.create(user_id=kwargs['user_id'], articles_id=kwargs['article_id']) article = Articles.with_state(kwargs['user_id']).get(pk=kwargs['article_id']) return_value = json.dumps({'likes_cnt': article.likes_cnt, 'liked_by_me': article.liked_by_me}) print(f'LikesCreateView return_value[{type(return_value)}]: ', return_value) except User.DoesNotExist: logging.critical('There was an access from an unauthorized user account') except Articles.DoesNotExist: logging.critical('An unauthorized article was accessed') … -
AmazonLinux2 Welcome Page shows over Nginx Installation
So, I'm setting up a backend api on Amazon Linux 2 and I have installed Nginx, set up a service systemd file that uses Gunicorn to run the django instance and create a sock file at /home/ec2-user/backend/testsite.sock.

How to implement dynamic filtering in Django ListView based on user input?
I'm working on a Django project where I need to display a list of items and allow users to filter the items based on various criteria. I'm using Django's generic ListView for displaying the items, but I'm not sure how to implement the dynamic filtering based on the user's input. Here's my current setup: models class Item(models.Model): name = models.CharField(max_length=100) category = models.CharField(max_length=50, choices=CATEGORY_CHOICES) price = models.DecimalField(max_digits=6, decimal_places=2) available = models.BooleanField(default=True) views: class ItemListView(ListView): model = Item template_name = "items/item_list.html" item_list.html {% for item in object_list %} <div class="item"> <h2>{{ item.name }}</h2> <p>Category: {{ item.category }}</p> <p>Price: {{ item.price }}</p> </div> {% endfor %} I'd like to allow users to filter the items by category, price range, and availability. What's the best way to implement this functionality in a Django ListView? Any guidance or examples would be much appreciated! -
Custimizing Django Admin (multiple registraion to a model)

Why can't the inherited class get updated value?

Only render part of django template if objects.all is not empty
I only want to render part of a django template if objects.all is not empty. Normally this is done like: <ul> {% for thing in things.all %} <li>{{ thing.name }}</li> {% empty %} <li>Sorry, nothing to list here</li> {% endfor %} </ul> But what if I want to have a heading or something that only shows if there's something to put in the list? I don't want the heading to be repeated each time the for loop runs. Is there something like {% not empty %} I could use, e.g.: {% if things.all not empty %} <h1>Here's the list of things</h1> <ul> {% for thing in things.all %} <li>{{ thing.name }}</li> {% endfor %} </ul> The above, however, throws a TemplateSyntaxError for django Not expecting 'not' as infix operator in if tag. How can we check if something is empty before running the loop? -
Render Submit Button in Same Row as Form Field in Django Crispy Forms
I'm using Django Crispy Forms, and rather than have the Submit button render below the rest of the fields, I want to move it to the same row as another field. My current Form code follows: class SetForm(forms.ModelForm): class Meta: model = Set fields = ['exercise', 'actual_weight', 'actual_reps', 'actual_difficulty'] helper = FormHelper() helper.form_method = 'POST' helper.layout = Layout( Row( Column('exercise', css_class='form-group col-md-12 mb-0'), css_class='form-row' ), Row( Column('actual_weight', css_class='form-group col-6 mb-0'), Column('actual_reps', css_class='form-group col-6 mb-0'), ), Row( Column('actual_difficulty', css_class='form-group col-6 mb-0'), Column(helper.add_input(Submit('submit', 'Submit', css_class='form-group btn-primary col-6 mb-0'))), ) ) This doesn't work though, the Submit button is still on its own row below the form, though the col-6 class does appear to be applied. I tried looking at this question, but it neither has answers nor uses Django Crispy Forms, as well as this one, but that one is focused on prepended text and it's not straightforward to modify the answers for this use case. Help please! -

The app checks the user answer and shows the result and then checks if the user answered the question or not. if the user answered the question the options will disable and **checks **the option that user selected but i got that error: TemplateSyntaxError at /questions/ Could not parse the remainder: '[question.id]' from 'answers[question.id]' html: ` {% for question in questions %} <div class="question"> <p>{{ question.text }}</p> <form method="post" action="{% url 'submit_answer' question.id %}"> {% csrf_token %} <input type="hidden" name="question" value="{{ question.id }}"> <input type="radio" id="option_1_{{ question.id }}" name="answer" value="1" {% if 1 in answers[{{question.id}}] %}checked{% endif %} {% if answers[question.id] is not None %}disabled{% endif %}> <label for="option_1_{{ question.id }}">{{ question.option_1 }}</label> <br> <input type="radio" id="option_1_{{ question.id }}" name="answer" value="2" {% if 2 in answers[question.id] %}checked{% endif %} {% if answers[question.id] is not None %}disabled{% endif %}> <label for="option_2_{{ question.id }}">{{ question.option_2 }}</label> <br> <input type="radio" id="option_1_{{ question.id }}" name="answer" value="3" {% if 3 in answers[question.id] %}checked{% endif %} {% if answers[question.id] is not None %}disabled{% endif %}> <label for="option_3_{{ question.id }}">{{ question.option_3 }}</label> <br> {% if not request.session.question_answers.get(str(question.id)) %} <button type="submit">Submit Answer</button> {% else %} <p>Your answer has been submitted.</p> {% endif %} </form> </div> {% endfor %} … -
django filter by related
my models: class Person(models.Model): name = models.CharField(max_length=255) class BankAccount(models.Model): iban = models.CharField(max_length=28) owners = models.ManyToManyField(Person, through='BankAccountPerson') class BankAccountPerson(models.Model): bank_account = models.ForeignKey(BankAccount, on_delete=models.RESTRICT, related_name = 'ownership') person = models.ForeignKey(Person, on_delete=models.RESTRICT, related_name = 'ownership') is_owner = models.BooleanField(null=True, blank=True) class Meta: unique_together= [['bank_account','person']] let's assume, that account no 1 has two owners: person:1 and person:2 And now if I filter like this: person=Person.objects.get(pk=1) collection = BankAccount.objects.filter(owners=person) will get only one row - with person1. But I'd like to get two rows: - with both people. Because I want to get accounts with owners, where one of owners is person I can do it with SQL: SELECT * FROM structure_bankaccount INNER JOIN "structure_bankaccountperson" ON ("structure_bankaccount"."id" = "structure_bankaccountperson"."bank_account_id") WHERE structure_bankaccount.id in (SELECT bank_account_id FROM "structure_bankaccountperson" WHERE "structure_bankaccountperson"."person_id" = 1) I can do it with two steps: owned_accounts = BankAccountPerson.objects.filter(person=person).values_list('bank_account_id') collection = BankAccount.objects.filter(id__in=owned_accounts) But I wonder if I can do it with some Q, F or other function in one django filter...
