Django model field through linked relationship
Is there a way to create a "virtual" field in a model linked to a field in a relationship? e.g. I have: class User(models.Model): organization = models.ForeignKey( "Organization", ... ) Organization model have a field name so I want to add a virtual field in User model (e.g organization_name) to be able to do user.organization_name instead of user.organization.name is it possible? -
Disaply Django Fieldset values according to previously selected option?
I'm using Django's built-in Admin functionality to support a web app's admin users. So far I'm also using mixins and "rest_framework - viewsets" library to have automated a generic CRUD API. In my admin.py files, I've used fieldsets to easily create a nice form to add new records with automatically included dropdowns, checkboxes, dateboxes etc. Great. A recent concern is that some of these some item selections should dictate the available options of other items. For example, if a person selects a state/province, the list of available cities should be restricted to those in just that state/province, instead of all the cities in the database. Is there any way to implement this behavior within the fieldsets syntax / without having to abandon viewsets and revert to manually coding this behaviour? -
Direct assignment to the forward side of a many-to-many set is prohibited. Use variants.set() instead
I am trying to create an api where a user can add a product with many variants. However, when I am sending raw json data from the postman I am getting above error. As you can see, a single variants can have multiple variants so the variants ids are sent at a same time from front end.

Django REST Framework token login also works with less fields than I have determined

Django ValueError: No route found for path 'ws/chat//'
I'm working on making a simple chat app using this tutorial from youtube (github link here: LINK). One potential issue is that the tutorial uses 2.x version of django but i have 3.1.7, but I had it working pretty well and was close, but then started getting this error: ValueError: No route found for path 'ws/chat//' When looking at my terminal, it keeps trying to reconnect over and over, possible becaues I'm using the ReconnectingWebSocket github javascript code. When I run redis-cli and type 'ping', I get 'PONG' in return so I think that is working properly. Below is my code: routing.py (I believe this seems most likely where the issue is) from django.urls import re_path from . import consumers websocket_urlpatterns = [ re_path(r'ws/chat/(?P<room_name>\w+)/$', consumers.ChatConsumer.as_asgi()), #new django ] wsgi.py: import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'django_project.settings') application = get_wsgi_application() settings.py: WSGI_APPLICATION = 'django_project.wsgi.application' ASGI_APPLICATION = 'django_project.asgi.application' # older version of django: 'django_project.routing.application' # Channels redis config: CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels_redis.core.RedisChannelLayer', 'CONFIG': { "hosts": [('127.0.0.1', 6379)], }, }, } views.py: chat/views.py from django.shortcuts import render import json from django.contrib.auth.decorators import login_required from django.utils.safestring import mark_safe def index(request): return render(request, 'chat/index.html') @login_required def room(request, room_name): return render(request, 'chat/room.html', … -
Redirect a form in same URL in Django
this is my first question so if i had made any mistakes excuse me. I have a template like below : I have and Object model and for that model i am making queries and returning to template. What i am trying to is when user select one of the objects and submits, I would like to redirect to the same page so based on the object that has been choosen i will have different result for the queries because this Object model related with different models. I am trying to do this in TemplateView. So far I have override the get_context_data() method and return all the Object records for select form and I can return queries results but for just one record which I specify in view. But I couldn't find a way to submit the form and depending on that record return the queries and redirect it to the same url. I am not sure the TemplateView is the best way to do it. Because of the privacy policy of my company i can not share any files for code. I just need a guidance or a clue about my view. Any help will be so appreciated. -
Grouping user in database by category object
I have experienced issues with this code and I truly need assistance. I need to allocate client to another client in a similar category or in the class category like a line or queue. There will be a sending clients and an accepting client the sending client will demand for an installment of the sum in my class or category (for instance $5, $10, $15) at that point the framework will naturally dole out the client to another client mentioning to get an installment in that classification.

Django class based view, how to return when using django_filter
I am using class based view because I employed django_filter. I also utilize django_tables2. When rendering request after POST I return the context.

How to optimize access to reverse ForeignKey?

Django_filters changing label, how to figure out default filter type
I am using django_filter, displaying it in my own way in template. I want to edit label of one of the filters. To do that I need to provide filter type. It works great in default but I can't figure out which filter type is used. This field in my model looks like this: class Zamowienie(models.Model): zam_kontrahent_fk = models.ForeignKey(Kontrahent, on_delete=models.CASCADE) On template it looks like typical select box. I figured out its not django_filters.ChoiceFilter but django_filters.ModelChoiceFilter. I tried using its queryset option but it only displays list of primary_keys (1 instead of 'name' field from the table foreign_key is) class ZamowienieFilter(django_filters.FilterSet): zam_status = django_filters.ModelChoiceFilter(label='Status', queryset=Zamowienie.objects.order_by('zam_kontrahent_fk').values_list('zam_kontrahent_fk', flat=True).distinct()) class Meta: model = Zamowienie fields = [ 'zam_kontrahent_fk', ] Is it correct way to handle that? I didn't find a way to log default filter behaviour, it would help a lot, simply copying this fragment. Any idea how to display values, not list of primary_keys? -

Django 500 Internal server error when authenticating against Django’s user database from Apache

I have been working on following model class Member(BaseModel): user = models.OneToOneField(User, on_delete=models.CASCADE) refer_code = models.CharField( max_length=20, unique=True, blank=True, null=True ) and the refer_code was set to be automatically generated when save method is called i.e during creation (not during update) here is my clean method and save method. def clean(self): if not self.user.is_member: raise DjangoValidationError({'user': _('User must member')}) def save(self, *args, **kwargs): if self._state.adding: self.refer_code = self.user.username super(Member, self).save(*args, **kwargs) post_save.connect(save, sender=User) I followed certain tutorials on youtube but got following error save() missing 1 required positional argument: 'self' I want post_save signal to be triggered during creation so I tried created = True but got error. Any help will be useful. -
PUT/PATCH method not updating the response but changes taking place in the database in DRF
I am working on an API using Django REST framework. In my case, I am using nested serializers so I am required to overwrite the .update method. Here's the required desc: Serializers Config Serializer class DeviceConfigSerializer(serializers.ModelSerializer): config = serializers.JSONField() context = serializers.JSONField() class Meta: model = Config fields = ['backend', 'status', 'templates', 'context', 'config'] Device Detail Serializer class DeviceDetailSerializer(serializers.ModelSerializer): config = DeviceConfigSerializer() class Meta(BaseMeta): model = Device fields = [ 'id', 'name', 'organization', 'mac_address', 'key', 'last_ip', 'management_ip', 'model', 'os', 'system', 'notes', 'config', ] def update(self, instance, validated_data): config_data = None if self.data['config'] is None and validated_data.get('config'): config_data_ = dict(validated_data.get('config')) config_templates = config_data_.pop('templates') config = Config.objects.create(device=instance, **config_data_) for template in config_templates: config.templates.add(template.pk) if validated_data.get('config'): config_data = validated_data.pop('config') # When config data is provided with PATCH requests if config_data: instance.config.backend = config_data.get( 'backend', instance.config.backend ) instance.config.status = config_data.get('status', instance.config.status) config_templates = config_data.get('templates') instance.config.templates.clear() for template in config_templates: instance.config.templates.add(template.pk) instance.config.context = json.loads( json.dumps(config_data.get('context')), object_pairs_hook=collections.OrderedDict, ) instance.config.config = json.loads( json.dumps(config_data.get('config')), object_pairs_hook=collections.OrderedDict, ) instance.config.save() return super().update(instance, validated_data) Device Detail Views class DeviceDetailView(RetrieveUpdateDestroyAPIView): serializer_class = DeviceDetailSerializer queryset = Device.objects.all() Now when I Send a PUT/PATCH request to its endpoint, It works fine and the fields in the database get updated, but since after the PUT/PATCH request …
