please correct the errors below. django admin
I'm relatively new to Django and I'm currently leveraging the built in admin app. I am receiving the following error("please correct the errors below") whenever try to add/save an inline child group and whenever I do a simple edit to the Parent.

Django - How to share data between ASGI and WSGI applications?
I make my project on Django, it has Gunicorn on WSGI, Daphne on ASGI. ASGI server needed only for handling Websocket protocol. Using Channels in Django for Websocket routing and handling. Nginx on static and proxy. Database is Mysql. Generally: is there a way to synchronise variable values in memory between ASGI and WSGI app without writing to database? TLDR: HTTP (wsgi) works for major interacting with database (for now, creating instances of models). Websocket (asgi) is planned to work with user controls (for now, connect to rooms, in future, would be in-game controls? rotate piece etc. The project is Tetris multiplayer, where users can create rooms, for example, for 2 or 4 players (parallel tetris fields), when created other players can connect into that rooms.) 'Under the hood' there is 'engine' (some data is stored in memory when the server runs): # engine/status.py active_rooms = {} when creating a new room, HTTP controller (from views.py) calls function: import engine.status as status from engine.Room import Room def create_room(id, size): new_room = Room(size) ... status.active_rooms[id] = new_room ... So, it writes a new key-value pair into dict (status.active_rooms), whers key is number(id), value is instance of class 'Room'. When other player … -

How does Django handle JOIN like filter statements?
I have some code that consists of 3 models, namely Course, Section and Lecture. A Course has many sections, a Section has many Lectures. Say i want to retrieve all the Lectures that belong to a particular Course, Course also has a property called 'title' so thats what will be used to filter. According to the tutorial i'm reading i should do this to get the lectures: Lecture.objects.filter(section__course__title = "title of course) This is pretty straightforward but what i'm wondering is how django is handling this under the hood. Some joins must be involved i can imagine, but according to the answer of this thread Does Django support JOIN? Django cannot make Joins. But when i look at the links he provides i can read that django does handle joins behind the scenes. So lets assume django does handle joins, how does it know when to make a left join or a regular join? A regular join can only be made when it is certain that every parent model has a reference to a child model, the field is marked not null. If it can be null then a left join should be used. Is django intelligent enough to know … -
how to use Django pagination with hidden search parameters
I am using Django for the backend (version 1.11.4) and python 3.6. I have a search form which has many searching parameters. I used POST method to submit the form. Everything is working fine. However, I made pagination using Django pagination. When I click on the next (through anchor tag). I got some error. Let me elaborate more here. I used post method to hide search parameters from users. However, I pass the page number through anchor tag which includes page number and the variable “path” caught up on the view function. This method working fine but it shows all searching parameters as well as the token when I click on the next link. When I passed the page number only, I got an error asking for the “result list” which is a variable inside of view function has the search result. The search result is inside the “if request.method==“POST”:" That is why it is undefined. Now what obvious to me from what I know. I have 3 methods to do the pagination using Django as follow: 1- I continue the same method. Catch up the path in the url as follow: path += "%s" % "&".join(["%s=%s" % (key, value) … -

Django Rest Framework ListSerializer Partial Update
I'm writing a serializer to provide multiple partial updates to a django model. I'm following the example implementation that appears in the DRF api guide, reproduced below and linked here: https://www.django-rest-framework.org/api-guide/serializers/#customizing-multiple-update. The following was retrieved from django-rest-framework documentation: serializer.py class BookListSerializer(serializers.ListSerializer): def update(self, instance, validated_data): # Maps for id->instance and id->data item. book_mapping = {book.id: book for book in instance} data_mapping = {item['id']: item for item in validated_data} # Perform creations and updates. ret = [] for book_id, data in data_mapping.items(): book = book_mapping.get(book_id, None) if book is None: ret.append(self.child.create(data)) else: ret.append(self.child.update(book, data)) # Perform deletions. for book_id, book in book_mapping.items(): if book_id not in data_mapping: book.delete() return ret class BookSerializer(serializers.Serializer): # We need to identify elements in the list using their primary key, # so use a writable field here, rather than the default which would be read-only. id = serializers.IntegerField() ... class Meta: list_serializer_class = BookListSerializer In my code I'm getting a NotImplementedError('update() must be implemented.') in my views.py when .save() is called on the serializer that is returned.

Django - How can i get this objects count based on this relationship
I have two models which are Influencer and InfluencerList. My model relationships are: User and InfluencerList have many-to-one relationship (one user can have many lists) Influencer and InfluencerList have many-to-many relationship (one influencer can be in multiple lists or one list can contain multiple influencers) I want to display logged in users each lists name and count (how many influencers are in it) I managed to list users own lists but i couldn't figured out how to get counts of that list. I suppose it should be done by using lookup (association) table. Here is my model.py: class Influencer(models.Model): # fields are not included for clarity def __str__(self): return self.url class InfluencerList(models.Model): name = models.CharField('Name:', max_length=20, blank=False) owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name='lists') influencers = models.ManyToManyField('Influencer', related_name='lists') def __str__(self): return self.name # some method like getCount() would be nice here view.py: class InfluencerListView(LoginRequiredMixin, ListView): model = Influencer context_object_name = 'Influencers' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) logged_in_user = self.request.user context['InfluencerLists'] = logged_in_user.lists.all(); return context I'm also not sure if i have to add a field like count to my InfluencerList model.

I have following code class StandardResultsSetPagination(PageNumberPagination): page_size = 100 page_size_query_param = 'page_size' max_page_size = 1000 class ListAllPrePayedV2(generics.ListAPIView): serializer_class = PrePayedSerializer pagination_class = StandardResultsSetPagination def get_queryset(self): queryset = PrePayed.objects # lcode lcode = self.request.query_params.get('lcode', None) if lcode is not None: queryset = queryset.filter(lcode=lcode) # lcode payed_by = self.request.query_params.get('payed_by', None) if payed_by is not None: queryset = queryset.filter(payed_by__icontains=payed_by) # order_by_date order_by_date = self.request.query_params.get('order_by_date', None) if order_by_date is not None: queryset = queryset.order_by('date') # order_by_payed_at order_by_payed_at = self.request.query_params.get('order_by_payed_at', None) if order_by_payed_at is not None: queryset = queryset.order_by('payed_at') if order_by_payed_at is None and order_by_date is None: queryset = queryset.order_by('pk') return queryset the problem is that sorting never works. is it possible in such set-up or I do something wrong ? if not possible in this, how can I do it ? -
django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured
I'm trying populate data in my modal using Faker but I got the error. here is my Code import os from faker import Faker from first_app.models import Topic, Webpage, AccessRecord os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myfirst.settings') import django django.setup() import random fakegen = Faker() topics = ['search', 'Social', 'Marketplace', 'News', 'Games'] def add_topic(): t = Topic.objects.get_or_create(top_name=random.choice(topics))[0] t.save() return t def populate(N=5): for entry in range(N): top=add_topic() fake_url=fakegen.url() fake_date=fakegen.date() fake_name=fakegen.company() webpg=Webpage.objects.get_or_create(topic=top,url=fake_url,name=fake_name)[0] acc_rec=AccessRecord.objects.get_or_create(name=webpg,date=fake_date)[0] if __name__=='__main__': print('populating script') populate(30) print('Completed') I think error is due to this line os.environ.setdefault but when I comment this line it doesn't populate data Below is the error django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJA NGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
