Django app deployment in AWS Beanstalk - Error after deployment - Internal Server Error
I have a django app deployed to AWS beanstalk. The first version was fine after following the official documentation: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html Then, I added a new feature using django-filter to my site.

Django rest framework creating Orders and order items
I want to create a Order and order items. For this i am simply creating new model object in views.py using CreateApiView but i am receiving error that "Serializer_class" should be included but i don't need serializer for this. //views.py class CreateOrder(CreateAPIView): def Post(self,request): header_token = request.META.get('HTTP_AUTHORIZATION', None) print(header_token) access_token = header_token.split(' ')[1] status,user = validate_token(access_token) cart=Cart.objects.get(user=user) print(cart) if cart: total=cart.total userprofile=UserProfile.objects.get(user=user) order,created=Order.objects.get_or_create(billing_profile=userprofile,total=total) cart_items=CartItem.objects.get(cart=cart) print(cart_items) for item in cart_items: itemid=item.item_id qty=item.quantity item_instance = Items.objects.get(item_id=item) order_item,created = OrderItems.objects.get_or_create(order=order, product=item_instance,quantity=qty) order.save() order_item.save() if created: item.delete() return Response (status=rt_status.HTTP_200_OK) I want to understand how to achieve this with or without serializer -

How can I subclass Django TextChoices to add additional attributes?
I want to use Django 3.0 TextChoices for a models.CharField choices option and also as an Enum in other places in my code. This is a simplified version of my code from django.db import models class ValueTypeOriginal(models.TextChoices): # I know Django will add the label for me, I am just being explicit BOOLEAN = 'boolean', 'Boolean' class Template(models.Model): value_type = models.CharField(choices=ValueType.choices) I am wanting to add an additional attribute to the enum members, something so that this call >>> ValueType.BOOLEAN.native_type bool works. bool here isn't a string, but the built-in python function This blog post described doing something like that with Enum by overriding __new__. class Direction(Enum): left = 37, (-1, 0) up = 38, (0, -1) right = 39, (1, 0) down = 40, (0, 1) def __new__(cls, keycode, vector): obj = object.__new__(cls) obj._value_ = keycode obj.vector = vector return obj Based on that I tried: class ValueTypeModified(models.TextChoices): BOOLEAN = ('boolean', bool), 'Boolean' def __new__(cls, value): obj = str.__new__(cls, value) obj._value_, obj.native = value return obj That almost works. I get access to the unique TextChoices attributes like .choices, but string comparison doesn't work like it should. >>> ValueTypeOriginal.BOOLEAN == 'boolean' True >>> ValueTypeModified.BOOLEAN == 'boolean' False I think … -
Django ignoring localisation settings when displaying a DateTime on a form
I have the Django settings in "settings.py": LANGUAGE_CODE = 'en-gb' TIME_ZONE = 'Europe/London' USE_I18N = True USE_L10N = True USE_TZ = True With a model in "models.py": class Foo(models.Model): date_time = models.DateTimeField(null=True, blank=True) And a form in "forms.py": class FooForm(forms.ModelForm): class Meta: model = Foo fields = ['date_time'] And in the template: <form method="post"> {% csrf_token %} <table> {{ form.as_table }} </table> <button type="submit">Submit</button> <button type="button" onclick="javascript:window.location='/dashboard';">Cancel </button> </form> But the date is shown on the screen in the form as "2020-12-20 10:11:12" for example. Why doesn't Django use my localisation settings and display the date as "day, month, year"? I tried adding to the form: date_time = forms.DateTimeField(input_formats=['%d/%m/%Y %H:%M']) ...but it didn't have any effect. To quote the manual: "The default formatting to use for displaying datetime fields in any part of the system. Note that if USE_L10N is set to True, then the locale-dictated format has higher precedence and will be applied instead." -

DRY way to rename ModelSerializer fields without duplicating model/field definitions?
Working with a legacy database with an awful schema and want to rename several ModelSerializer fields without having to redefine fields already defined on the model. Here's an example model: class LegacyItem(models.Model): # Note: ignore things that feel "wrong" here (just an example) legacyitem_id = models.IntegerField(primary_key=True) legacyitem_notes = models.CharField(max_length=4000, blank=True, null=True) directory_id = models.ForeignKey('Directory', models.DO_NOTHING) created_by_directory_id = models.ForeignKey('Directory', models.DO_NOTHING) created_date = models.DateField(auto_now_add=True) modified_by_directory_id = models.ForeignKey('Directory', models.DO_NOTHING) modified_date = models.DateField(auto_now=True) Here's a working serializer: class LegacyItemSerializer(serializers.ModelSerializer): class Meta: fields = '__all__' model = LegacyItem read_only_fields = [ 'created_date', 'modified_date', ] The goal is to bulk rename model fields for the API so we can abstract away the awful schema. Here's a working serializer showing the sort of renaming we want to do: class LegacyItemSerializer(serializers.ModelSerializer): created_by = serializers.PrimaryKeyRelatedField( read_only=True, source='created_by_directory_id', ) customer = serializers.PrimaryKeyRelatedField( queryset=Directory.objects.all(), source='directory_id', ) id = serializers.PrimaryKeyRelatedField( read_only=True, source='legacyitem_id' ) modified_by = serializers.PrimaryKeyRelatedField( read_only=True, source='modified_by_directory_id', ) notes = serializers.DateField(source='legacyitem_notes') class Meta: fields = [ 'id', 'customer', 'notes', 'created_by', 'created_date', 'modified_by', 'modified_date', ] model = LegacyItem read_only_fields = [ 'created_date', 'modified_date', ] All we want to do is rename the fields. We don't want to change the validation and would rather keep most of that validation on the model and … -
Django: Automatically update database field to True with background task when condition is met
I have a Model Job which has a field filled. I want to automatically update filled to True if the current_date and time is equal to the Job's end_date and time. The end_date is set when creating the job. I am using a background task to check all Jobs in the DB and repeat the process always, but I can't get it to work. Here is my code Model.py class Job(models.Model): # title, description, requirements, job type etc. end_date = models.DateTimeField(null=True, blank=True) current_date = models.DateTimeField(null=True, blank=True) filled = models.BooleanField(default=False) created_at = models.DateTimeField(default=timezone.now) def __str__(self): return self.title task.py from django.utils import timezone queryset = Job.objects.all() @background(schedule=60) def auto_mark_as_filled(jobs): for job in [jobs]: job.date = timezone.now() if job.end_date == job.current_date: job.filled = True job.save() return jobs # repeat always/every seconds auto_mark_as_filled(queryset, repeat=1) I get TypeError: Object of type QuerySet is not JSON serializable I don't want to use celery as a background task is easier to implement.

Django do something when model instance created
I'm looking to update a user's coin count in their profile whenever I create a promo code redemption object from a model. Is there a method that runs when the object is created so I can update a field in the users profile from the promo code redemption model? I tried init() but the arguments were no longer being filled in and saved in the model and I'm just looking to run extra code rather than adding custom fields. I saw the signals file mentioned but wouldn't it be simpler to have it be done automatically through the model as a method? class Promo_Code_Redemption(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) amount = models.DecimalField(max_digits=9,decimal_places=2) date = models.DateTimeField(default=timezone.now) code = models.ForeignKey(Promo_Code, on_delete=models.CASCADE) code_text = models.TextField() revenue_type = "Promo code" def __str__(self): return self.code.code class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) withdrawal_email = models.EmailField(max_length=254) currency_total = models.DecimalField(max_digits=9,decimal_places=2,default=0.00) currency_earned_all_time = models.DecimalField(max_digits=11,decimal_places=2,default=0.00) def __str__(self): return self.user.username views.py @login_required def codes(request): if request.method == 'POST': form = Promo_code_redeem_form(request.user, request.POST) if form.is_valid(): promo_code = form.cleaned_data.get('code_text') #create promo code redemption instance Promo_Code_Redemption.objects.create(user=request.user, amount=Promo_Code.objects.get(code=promo_code.lower()).internal_currency_value, code=Promo_Code.objects.get(code=promo_code.lower()), code_text=promo_code) messages.success(request, f'Promo code redeemed succesfully!') return redirect('codes') else: form = Promo_code_redeem_form(request.user) codes = Promo_Code_Redemption.objects.filter(user=request.user).order_by('-date') total_codes_redeemed = Promo_Code_Redemption.objects.filter(user=request.user).count() total_codes_value = Promo_Code_Redemption.objects.filter(user=request.user).aggregate(Sum('amount')) total_codes_value = total_codes_value['amount__sum'] context = { … -

Custom Django messages and adding extra context to Django change_view
I am using SESSION_COOKIE_AGE and added custom JS to refresh the page after the session expires to log a user out after a certain time of inactivity. I now was to add a message to the logout page to let the user know why they were logged out. According to Django Docs I have to add my custom message as context to the view and then call it on the template. The logout function is used for mainly for the change_form.html template, but of course SESSION_COOKIE_AGE works everywhere. Where is the view for change_form so I can add this context? I see from the docs it is called change_view, but not what file/folder it is in can I cannot find it for the life of me. Would there be an easier way to show this message no matter where the user was logged out from? -

How to create a responsive (the user being able to modify) graph to obtain inputs from it?
So I'm remodeling this website where at some point of a form the user has to enter its consumption profile in percentages (e.g. "I 50% of the energy on mondays 20% on Fridays, 30% on sundays"). My idea is to place some kind of graph (like the one I attached, imagine % in y axis and weekdays in x-axis) where the user could move up and down the bars to visually enter its consumption and finally, on form submit, grab the inputs from it using django, JS or Jquery. I don't know where to start or even if it is possible. I kindly ask you for help. :) -

Is there any problem in my code? @login_required def Feedback(request): if request.method == 'POST': Feedback_Form = FeedbackForm(request.POST) Feedback_Form.instance.user = request.user if Feedback_Form.is_valid(): Feedback_Form.save() username = request.user messages.success(request, f'Thanks for your Feedback. Thanks for using our site, {username}.') return redirect('Feed-back') else: Feedback_Form = FeedbackForm() return render(request,'users/feedback.html',{'feedback_form': Feedback_Form}) -
How to handle a legacy database in the Django framework
I'm working on an django app that needs to access a very large (mysql) database, the db has no foreign keys whatsoever. I need to do querys on multiple tables.The way i'm doing it is VERY ineficient and involves doing multiple loops: ''' {% for flower in especies_id %} <td>{{flower.especies}}</td> {% for family in family_id %} {% if family.family_id == flower.family_id %} <td><a class="nav-item active" href="/home"> {{family.family_name}}</td></a> {% endif %} {% endfor %} {% endfor %} ''' Is there a way to handle this db with the django shell maybe?Javascript? Or refactor the db entirely
