Why isn't my .Dockerignore file not ignoring files?
When I build the container and I check the files that should have been ignored, most of them haven't been ignored. This is my folder structure. Root/ data/ project/ __pycache__/ media/ static/ app/ __pycache__/ migrations/ templates/ .dockerignore .gitignore .env docker-compose.yml Dockerfile requirements.txt manage.py Let's say i want to ignore the __pycache__ & data(data will be created with the docker-compose up command, when creating the container) folders and the .gitignore & .env files. I will ignore these with the next .dockerignore file .git .gitignore .docker */__pycache__/ **/__pycache__/ .env/ .venv/ venv/ data/ The final result is that only the git & .env files have been ignored. The data folder hasn't been ignored but it's not accesible from the container. And the __pycache__ folders haven't been ignored either. Here are the docker files. docker-compose.yml version: "3.8" services: app: build: . volumes: - .:/django-app ports: - 8000:8000 command: /bin/bash -c "sleep 7; python manage.py migrate; python manage.py runserver 0.0.0.0:8000" container_name: app-container depends_on: - db db: image: postgres volumes: - ./data:/var/lib/postgresql/data environment: - POSTGRES_DB=${DB_NAME} - POSTGRES_USER=${DB_USER} - POSTGRES_PASSWORD=${DB_PASSWORD} container_name: postgres_db_container Dockerfile FROM python:3.9-slim-buster ENV PYTHONUNBUFFERED=1 WORKDIR /django-app EXPOSE 8000 COPY requirements.txt requirements.txt RUN apt-get update \ && adduser --disabled-password --no-create-home userapp \ && apt-get -y … -
Serializers.validated_data fields got changed with source value in DRF
I am trying to create an api, where user can create programs and add rules to them. Rules has to be executed in order of priority. I am using Django rest framework to achieve this and I am trying to achieve this using Serializer without using ModelSerializer. Provide your solution using serializers.Serializer class One program can have many rules and one rule can be in many programs. So, I am using many_to_many relationship and also I want the user to change the order of rules in a program, to achieve this I am using a through table called Priority, where I keep track of relationship between a rule and a program using priority field models.py class Program(models.Model): name = models.CharField(max_length=32) description = models.TextField(blank=True) rules = models.ManyToManyField(Rule, through='Priority') class Rule(models.Model): name = models.CharField(max_length=20) description = models.TextField(blank=True) rule = models.CharField(max_length=256) class Priority(models.Model): program = models.ForeignKey(Program, on_delete=models.CASCADE) rule = models.ForeignKey(Rule, on_delete=models.CASCADE) priority = models.PositiveIntegerField() def save(self, *args, **kwargs): super(Priority, self).save(*args, **kwargs) serializers.py class RuleSerializer(serializers.Serializer): name = serializers.CharField(max_length=20) description = serializers.CharField(allow_blank=True) rule = serializers.CharField(max_length=256) def create(self, validated_data): return Rule.objects.create(**validated_data) def update(self, instance, validated_data): instance.name = validated_data.get('name', instance.name) instance.description = validated_data.get('description', instance.description) instance.rule = validated_data.get('rule', instance.rule) instance.save() return instance class PrioritySerializer(serializers.Serializer): rule_id = serializers.IntegerField(source='rule.id') rule_name … -

How to remove results with same value with django ORM?
I have a query that returns data that will be displayed in the browser as a line chart. Depending on the period chosen, this can represent a rather huge number of results (~25K max). Most of the time these values do not change, on average on 25 000 results I have about 8000 different values. I think it would be a real optimization if I only return these 8000 values instead of the 25 0000. My Model: class TechnicalData(models.Model): name = models.CharField(_('Name'), max_length=80) value = models.CharField(_('Value'), max_length=80) value_type = models.CharField(_('Value type'), max_length=20) date_time = models.DateTimeField(_("timestamp")) machine = models.ForeignKey("machine.Machine", verbose_name = _("machine"), related_name="technical_data_machine", on_delete=models.CASCADE) class Meta: verbose_name = _("TechnicalData") verbose_name_plural = _("TechnicalDatas") ordering = ["-date_time"] def __str__(self): return self.name If the "value" field does not change during a given period (date_time), I would like to remove the "duplicate/same" values. Today I have this view: class TechnicalDataViewSet(viewsets.ViewSet): """ A simple ViewSet for listing or retrieving technical data. """ permission_classes = [permissions.IsAuthenticated] pagination_class = LargeResultsSetPagination def list(self, request): id_machine = self.request.query_params.get('id_machine') name = self.request.query_params.get('name') only_last = self.request.query_params.get('only_last') names = self.request.query_params.get('name__in') date_start = self.request.query_params.get('date_start') date_end = self.request.query_params.get('date_end') queryset = TechnicalData.objects.all() if id_machine: queryset = queryset.filter(machine__id=id_machine) if name: queryset = queryset.filter(name=name) if names: names = … -

Save Form after successful stripe Payment
I have a model form that the user fills. This form contains a file field as well. After filling in the form once the user presses the submit button, the form is saved to the database using POST after getting verified. What I would like to do is once the user clicks the submit button, they should be taken to another page to make a payment. The payment page will be created using Stripe Payment Intent and not Stripe Checkout. Once they have successfully paid I would like to save the data that the user have filled in the form.I have created the Stripe Payment page and I can see payments being made on the Stripe dashboard but I would like to save the data that the user has filled in the form after successful payment. How do I go about doing this in Python3 , Django? -
Django sales campaign model with list of foreign keys that can only appear in one sales campaign?
I want to create a sales campaign which stores a list of books (Items). But the book should only be applied to one sales campaign — ie. it should not be able to appear in two campaigns. I have the following model: class Campaign(models.Model): campaign_name = models.CharField(max_length=50, null=False, blank=False, default='Special Offer') included_items = models.ManyToManyField(Item, blank=True) active = models.BooleanField(default=True) fixed_price = models.DecimalField(max_digits=6, blank=True, null=True, decimal_places=2) But I think the included_items field might be of the wrong field type. From reading other questions and the Django manual, I think I may be approaching this back to front. Perhaps I should be tackling this from the Item model instead? (Shown below for reference) class Item(models.Model): sku = models.CharField( max_length=10, null=True, blank=True, default=create_new_sku) title = models.CharField(max_length=254) genre = models.ManyToManyField('Genre', blank=True) author = models.ManyToManyField('Author', blank=True) description = models.TextField() age_range = models.ManyToManyField( 'Age_range') image_url = models.URLField(max_length=1024, null=True, blank=True) image = models.ImageField(null=True, blank=True) price = models.DecimalField(max_digits=6, decimal_places=2, default=0.00) discount = models.DecimalField(max_digits=2, decimal_places=0, default=0) set_sale_price = models.DecimalField(max_digits=6, decimal_places=2, default=0.00) original_sale_price = models.DecimalField(max_digits=6, decimal_places=2, null=True, blank=True) final_price = models.DecimalField(max_digits=6, decimal_places=2, null=True, blank=False, editable=False) -

Ger all form data as a list, iterate over it and dilplay them in a table on template
I am working on a simple school project where students and teachers are registered as users. class monitors get a student list of their class and monitors have to submit and send a report to class teacher that all the students in the class are present for a certain lesson. So I have created a student model where parent class is the admission number. Then I have filtered a certain class (ex: Grade-6) and render them in to a template (grade-6 dashboard) and gave access to grade 6 class monitor. So the monitor can see all the student with their admission number on monitor dashboard. Then I have insert a select option with each student to select yes or no to say he or she is present or not. Then submit. After submitting in my view.py I get all the data as request.POST. But after saving the form (form.save()) I get last student details only. But all the details are in request.POST but I cannot get them to render in to a template. I dont know how. So I tried getting them as a list or a dict but couldnt.

using custom function inside ModelViewset in Django rest framework
I always used APIView for writing all the CRUD operations in a single api view as because APIView already recognises which actions to be performed on the basis of http methods that comes from the request from the frontend. Recently I came across some code that is written using ModelViewset. Here a custom function is defined instead of list, create, destroy.

How to add extra fields outside the list of items in modelView ? (like count for pagination)
I'm looking for the best way to add additional fields to the get list return of a ModelView. I have the following model: class Sale(models.Model): total = models.FloatField(_("Total")) name = models.CharField(_("Name")) [...] When I do a get list on this model, I get the following json: { "count": 0, "next": "http://example.com", "previous": "http://example.com", "results": [ { "id": 0, "name": "example", "total": 0, [...] } ] } I would like to add 2 fields min_total and max_total to the result (at the same level as "count"). Example: { "count": 0, "next": "http://example.com", "previous": "http://example.com", "min_total": 0, "max_total": 100, "results": [ { "id": 0, "name": "example", "total": 100, [...] } ] } My View: class SaleViewSet(viewsets.ReadOnlyModelViewSet): """ A simple ViewSet for listing or retrieving sales. """ permission_classes = [permissions.IsAuthenticated] filter_backends = [DjangoFilterBackend, filters.OrderingFilter] filter_fields = ['client', 'machine', 'date_time', 'total'] ordering_fields = '__all__' def get_serializer_class(self): if hasattr(self, 'action') and self.action == 'list': return SaleListSerializer if hasattr(self, 'action') and self.action == 'retrieve': return SaleRetrieveSerializer return SaleSerializer def get_queryset(self): queryset = Sale.objects.all().select_related('client') user = self.request.user if user.is_staff: cache_key = 'list_sale_sales' else: queryset = queryset.filter(client=user.profil.client) cache_key = f'list_sale_sales_client_{user.profil.client.pk}' return cache.get_or_set(cache_key, queryset, 60) To get these 2 values I just have to make these 2 requests: Sale.objects.all().aggregate(min=Min("total")) … -
