Show two tables specific column data into one list?
I have two tables Customer and Subscription in which Customer has the list of customers and Subscription contains the Customer and Packages. In the customer list i want to show how many packages each customer has. Subscription Model class Subscription(models.Model): client = models.ForeignKey(Customer, on_delete=models.SET_NULL, blank=True, null=True, related_name="subscriptions") package = models.ForeignKey(Package, on_delete=models.SET_NULL, blank=True, null=True) valid_start_date = models.DateTimeField() valid_end_date = models.DateTimeField() usage_count = models.IntegerField(null=True) status = models.CharField(max_length=20) transaction = models.BigIntegerField(blank=True, null=True, default=0) created_at = models.DateTimeField() updated_at = models.DateTimeField() Customer Model class Customer(AbstractBaseUser): first_name = models.CharField(max_length=250, blank=True, null=True) last_name = models.CharField(max_length=250, blank=True, null=True) email = models.EmailField(unique=True, blank=True, null=True) mobile_number = models.BigIntegerField(blank=True, null=True) password = models.CharField(max_length=1000, blank=True, null=True) gender = models.CharField(max_length=10, blank=True, null=True) profile_picture = models.ImageField(upload_to="user_data/profile_picture", blank=True) address = models.CharField(max_length=500, blank=True, null=True) country = models.ForeignKey(Countries, on_delete=models.SET_NULL, blank=True, null=True) state = models.ForeignKey(States, on_delete=models.SET_NULL, blank=True, null=True) city = models.ForeignKey(Cities, on_delete=models.SET_NULL, blank=True, null=True) pincode = models.IntegerField(blank=True, null=True) number_of_logins = models.IntegerField(blank=True, null=True) is_active = models.BooleanField(default=True) gcm = models.CharField(max_length=250, blank=True, null=True) created_at = models.DateTimeField(blank=True, null=True) updated_at = models.DateTimeField(blank=True, null=True) USERNAME_FIELD = "email" Expected Result : I want to show the package field data from Subscription Model into the list of Customer model. Actual Result : Only Customer field data -

Django Max count of foreign key set
class Blog(models.Model): pass class Article(models.Model): blog = models.ForeignKey(Blog, on_delete=models.CASCADE) b = Blog.objects.filter(...) Given b, is it possible to find with a single query the highest count of associated articles? I could do that by iterating: max_count = 0 for blog in b: if b.article_set.count() > max_count: max_count = b.article_set.count() Is there a more efficient way that uses the ORM/SQL? -
Django database access optimization: Efficient creation of many-to-many relationships (between existing objects)
I'm using Django 2.2 with a PostgreSQL database. I have two models: Gene and Annotation and need to create and link (many-to-many) thousands of Genes and Annotations at the same time. class Gene(models.Model): identifier = models.CharField(max_length=50, primary_key=True) annotation = models.ManyToManyField(Annotation) class Annotation(models.Model): name = models.CharField(max_length=120, unique=True, primary_key=True) I already found a way to create the objects very efficiently: Gene.objects.bulk_create([Gene(identifier=identifier) for identifier in gene_id_set]) This is my Django-docs-inspired way to create relationships: relationships = { 'gene1': ['anno1', 'anno2'], 'gene2': ['anno3'], ... } for gene in relationships: gene = Annotation.objects.get(pk='gene1') gene.annotation_set.set([Annotation.objects.get(pk=anno) for anno in relationships[gene]) But this is very clumsy: It hits the database 4 times! Is there not a better way, using Django-built-in-tools or raw SQL queries? The many-to-many table (myapp_gene_annotation) looks like this: id gene_id annotation_id 1 gene1 anno1 2 gene1 anno2 3 gene2 anno3 ... -
How to validate template versioned form fields in django without using django forms?
I wrote a small authentication application where i used manual template rendering. I can fetch and update data from from forms but i just want to validate the fields.

How to order_by related field date with annotation?
i have this model : class Node(MPTTModel): parent = TreeForeignKey('self', on_delete=models.CASCADE, blank=True, null=True, related_name='children') name = models.TextField(blank=True, null=True) which have this related model : class Views(models.Model): related_tree = models.ForeignKey(Node, on_delete=models.CASCADE, blank=True, null=True, related_name='related_views') views_count = models.PositiveIntegerField(null=True, blank=True, default=0) user = models.ForeignKey(CustomUser, on_delete=models.CASCADE, blank=True, null=True) view_date = models.DateTimeField(default=timezone.now) What i am trying to do is to order a queryset of the first model by the view date of the second one, this is the view that i have tried : last_viewed_trees = Node.objects.filter(tree_type='root').order_by('-related_views__view_date') In that one the result is correct but i have a duplicate view_date of many users. I have tried also this one without success : last_viewed_trees = Node.objects.filter(tree_type='root').annotate(time_of_views= Min('related_views__views_count') ).order_by('-time_of_views') last_viewed_trees = Node.objects.filter(tree_type='root').annotate(time_of_views= Max('related_views__views_count') ).order_by('-time_of_views') Nothing have worked for me, there is something that i am missing, but i cannot identify it. -
Assigning several model instances of one Model to another Model, and then comparing them?
I have a model called Hero, which has about 500 different objects. I'm having the user select 4 instances of Hero in a form, and assigning them to a Match model to register what Heroes they played with. I've tried creating a Deck model, that could contain the 4 heroes and then assign that Deck model in Match model and form, but then the user can't select a new combination, only current Deck combinations. This works fine in the adminpanel, where I can add new combinations, but the user doesn't get that opportunity. It's not quite what I want and I can't wrap my head around, is how I can then later compare two instances of Deck or the selected Heroes in Match to see if the user selected the same Heroes in their Deck/Match and/or count how many times that specific combination of Hero is used in a deck/Match. In short: What I want is for the user to, through a form, select 4 Hero objects and save them to a Deck model. If their specific combination of selected Heroes is already in Deck, then it should register it under that. I know it's confusing, but that's owing to … -

Django list of files returns an empty array
I'm starting with Django, so I'm pretty new to this. I'm sending a file to the Django server, saving it, trying to get the last file (the one I just send) from the saved folder and then I want to perform some processes on that file, after that I want to delete the original file. I already managed to upload and save the file to the filesystem, but I'm having trouble selecting this file from the folder. I'm trying select and remove it this way: @api_view(['POST', 'GET']) def geojson_to_shape_view(request): if request.method == 'POST': serializer = FileSerializer(data=request.data) if serializer.is_valid(): # serializer.save() calls .create() in serializers.py file = serializer.save() # Get last saved file print("Analyzing last posted file...") list_of_files = glob.glob('../media/temp_files/*') print(list_of_files) if list_of_files: latest_file = max(list_of_files, key=os.path.getctime) print("Deleting last posted file...") try: os.remove(latest_file) pass except: print("Can't remove the file") return Response(FileSerializer(file).data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) And this code returns: Analyzing last posted file...

Django: Query with foreign key
I have two models called Thread and Post. A Thread has 0..* posts. Now, I need a query that gets all threads sorted by the datetime of the latest post in the thread. In case there is no post yet in the thread, the datetime of the thread creation is important. Honestly, I am a bit overwhelmed with the database query. Thread: created_at = DateTimeField() Post thread = ForeignKey(Thread) My current approach does not work: newest = Post.objects.filter(thread=OuterRef('pk')).order_by('-created_at') threads = Thread.objects.annotate( latest_post=Case( When(Exists(Subquery(newest.values_list('created_at')[:1])), then=Value(Subquery( newest.values_list('created_at')[:1]), ), default=Value(Thread.created_at)))).order_by('-latest_post') Can someone help me? -
Inconsistency between test and django: :int() argument must be a string but also TypeError: string indices must be integers
I have an API view that receives a request and creates some data. It works fine. When I am running my test I wrote with pytest I receive this error: node_name = (data_node['name']) TypeError: string indices must be integers When I change my code to be an integer like this: node_name = int((data_node['name'])) my django view gives me this error: :int() argument must be a string And I am like... whuat?!

Cancel the POST when the page is refreshed
My problem is : When an user refresh the Form the data in the Form is sent. I have a Form with request POST. The user write his name, mail and message. If the mail is correct the message is sent.

Avoid non-specified attributes on model creation
I want to create an object in Python but, since I'm using Django, I don't want to save those attributes with None or null value. When I create an object passing a couple of arguments, those attributes passed are assigned correctly; but the rest, which I wish were not created, are assigned the value "None" models.py: from djongo import models from mongoengine import * class MyClass(Document): _id = StringField(max_length=20, primary_key = True) atr1 = StringField() atr2 = StringField(max_length=300) atr3 = EmbeddedDocumentField(AdministrativeOptions) atr4 = EmbeddedDocumentField(CancelationPolicy) atr5 = StringField(max_length=50) atr6 = IntField() views.py: def index(request): a = MyClass( _id = 'TestID', atr1 = 'Xxxx' ) for key in a: print(str(key) + " = " + str(a[key])) a.save() What I get from the print loop is: _id = TestID atr1 = Xxxx atr2 = None atr3 = None atr4 = None atr5 = None atr6 = None Which means I am saving an object full of empty data. I would like to save a MyClass object with just the specified attributes in order to save space in memory. -
