How can I create a view that retrieves all objects with matching primary key in url?
I have two models that form a one-to-many relationship. One pallet has multiple images associated with it. models.py class Pallet(models.Model): pallet_id = models.IntegerField(primary_key=True) def __str__(self): return str(self.pallet_id) class Meta: ordering = ('pallet_id',) class Image(models.Model): created = models.DateTimeField(auto_now_add=True) pallet = models.ForeignKey(Pallet, on_delete=models.CASCADE) image = models.FileField(upload_to="") def __str__(self): return str(self.created) I'm trying to create a view where I get all images associated with a particular pallet_id from the url. serializers.py class ImageSerializer(serializers.HyperlinkedModelSerializer): pallet = serializers.PrimaryKeyRelatedField(many=True, read_only=True) class Meta: model = Image fields = '__all__' class PalletSerializer(serializers.ModelSerializer): class Meta: model = Pallet fields = '__all__' urls.py urlpatterns = [ url(r'^pallets/', include([ url(r'^(?P<pk>[0-9]+)/$', views.PalletDetail.as_view(), name='pallet-detail'), ])), ] I think the issue is in the views.py with the PalletDetail class. I am confused on how to write the view based on the primary key from the URL. I've tried to use **kwargs['pk'] but does using this make it a function-based view? If so, would it be bad form to mix class-based and function-based views? How can I get similar behavior from class-based views? I'm really struggling with the views here: views.py class PalletDetail(generics.RetrieveUpdateDestroyAPIView): queryset = Image.objects.prefetch_related('pallet_id').all() serializer_class = ImageSerializer -
Django 2 lose the change on models even after saving the update

How to validate django custom model field attributes?
I am writing custom model field called EnumField for mysql database, which looks like below class EnumField(models.Field): def __init__(self, *args, **kwargs): self.values = kwargs['values'] kwargs['choices'] = [(key, value) for key, value in self.values] super().__init__(*args, **kwargs) def db_type(self, connection): enum_values = ",".join([key for key, value in self.values]) return f"ENUM({enum_values})" I hope this works well, but i can't figure out way to enforce constraints such as the values attribute should be list or tuple., and values attribute should contain unique key and values. for example if anyone tries to use EnumField like below with duplicate values i need to throw exception., How can i achieve that. option = EnumField(values=(('Y', 'yes'), 'Y', 'Yes')) -
How to enforce Uniqueness of a ManyToMany with through joiner to outside table
I don't even know if my title accurately describes what I'm looking for. So here it goes. I have 4 models: Person, Project, Group, GroupMember (joiner).

No admin address given, so no admin http server started
Running our docker-compose up code on macs and ubuntu causes no problems. Having some issues when we run it on Windows, and we have enough people on the project using Windows that we need to figure out the problem.

How to generate Queues per user inside celery?
So I'm trying to move blocking stuff from web request as background tasks and leveraging queue. I'm also new to messaging and pub/sub. Users push there data and it is processed and later users are notified about that. I made a celery setup for this and found that it doesn't satisfy my use case for having private queue for every user for their own tasks. I tried specifying creation of missing queues and during worker spawning (sending queue names comma separated) and also listing them in queues settings as stated in previous answers over internet for "dynamic queue creation with celery". It creates the queues, but doesn't when I specify different queue name than specified names in settings and command line. The solution is to spawn more workers with queue names which doesn't satisfy the use case as there will be millions of data processing requests. I've found that python-rq has Queue object initialization with its name, which I think creates new queue. If it does, will shifting to RQ will be right? redis_conn = Redis() q = Queue('some_queue', connection=redis_conn) What I want is per user queue for their own tasks in the background. I don't see any solutions online … -

Why is django get request returning 400 status code when get parameter is not included in the request url?
I have created rest API endpoint which requires one get parameter 'id'. When I am including 'id' in url it is working fine but when I am excluding 'id' it is giving 400 status code. I am using Django 1.10 as web framework and Django rest framework for APIs. The class based view is written to return empty object if 'id' parameter is not present in the get request. I have tried different url patterns but nothing seems to work. The url pattern is as below- urlpatterns = [ url(r"^scheme/", APIScheme.as_view()), ] I am using Postman to send request. For url {{base}}/scheme/?id=1 I am getting expected result but for url {{base}}/scheme/ it is returning status code as 400. What can be the reason for this and how to debug this? -
Django how to make createsuperuser checks for duplicate email adress
def create_superuser(self, username, email, password=None): user = self.create_user( username, email, password=password ) user.is_admin = True user.is_staff = True user.active = True user.save(using=self._db) return user I have made a custom user model. When I call createsuperuser, if the username I entered is already in the database, it will prompt 'Error: That username is already taken.' But if I entered a email address which already exists in the database, it will not prompt the email has been taken error. Instead, it let me pass through and gave me the following error after I entered the password: django.db.utils.IntegrityError: UNIQUE constraint failed: users_customuser.email Is there a way to make it also check the email address like the way it checks the username?
