Django model method to get recursive children in M2M table inheritance
I am using table inheritance in Django and the base ModelA has a ManyToMany recursive field to itself called children. Then I have a ModelB that inherits from ModelA. The issue here is that when I query the children of an instance in ModelB, they are pointed to their equivalents in ModelA. What I would like to accomplish is that an instance of ModelB would return a queryset of children also of ModelB. I can do this using a method _children so it doesn't collide with the field name and have it return the correct model instances. Is there any way that I could instead have modelB.children.all() return the children with the correct model? I know I could use _children() but I would like to call it as an attribute and not a method(). The reason for all of this is that the table inheritance was added later in the game and all the instances will be migrated to these new models soon. Plus, children is broadly used in my project so it would be a hassle to change it all to _children. class ModelA(models.Model): id = models.UUIDField(primary_key=True, editable=False, default=uuid.uuid4) children = models.ManyToManyField( 'self', related_name='parents', symmetrical=False ) def _children(self): return … -
Writing if else statements in Django's Admin.py
I would like to have my Django admin collapse certain information if the user is new and cannot seem to figure out how to write an if else statement within the admin.py. Here's a general example models.py class User(models.Model): name = models.CharField() is_new = models.BooleanField(default=True) class NewUserInfo(models.Model): join_date = models.CharField() ''' admin.py ''' class NewUserInfoInline(admin.StackedInline): model = NewUserInfo # Here is where I'd like the if else statement I believe # Something like this **if user.is_new is False: classes = ['collapse']** class UserAdmin(admin.ModelAdmin): inlines = [NewUserInfoInline] -
Saving instances of model to ManyToMany field thows AttributeError 'Post' object has no attribute 'save_m2m' but when db is checked, has saved
My Django 3.1.7 blog app has a Post model with a tags field, which is a ManyToManyField to the PostTag model. I want my users to be able to select from some popular tags, or add their own in the new_tags field I created in models.py. new_tags does not exist in the Post model. My idea was to grab the string of "new" tags, split it at the spaces, then check if the tag already existed - creating it if it does exist. That bit of code is working, as new tags are being added to the database. My issue comes when I try to attach these new tags to the instance of Post being updated with the form. I have read loads of SO posts, and have arrived at the view code below. This does save the new tags to the Post instance in the database. However, on submitting the form it still throws an AttributeError: 'Post' object has no attribute 'save_m2m' However if I remove the post.save_m2m() line, the instances are created, but are not attached to my Post instance. views.py class EditPostView(LoginRequiredMixin, UpdateView): """ Renders view to edit an existing post """ model = Post template_name = … -

Django filter model by method result
I'm looking to filter a model (InventoryItem) by a custom defined method (current_location) that is the filtered queryset of another model (InventoryMovement). I've tried reading the Django documentation, but can't make out exactly how they are using model managers to achieve something like this. One example of what I'm trying to achieve would be something like: InventoryItem.objects.filter(current_warehouse='A') Code is: class InventoryAddress: def __init__(self, warehouse, location, sublocation): self.warehouse = warehouse self.location = location self.sublocation = sublocation class InventoryItem(models.Model): inventory_sku = models.CharField(max_length=20, unique=True, primary_key=True, null=False, blank=False, verbose_name="Inventory SKU") authenticated = models.CharField(max_length=2, choices=yes_no_choices, verbose_name='Authentication Status') # GenericForeignKey for Specific Product content_type = models.ForeignKey(ContentType, on_delete=models.PROTECT, null=True) object_id = models.CharField(max_length=50) content_object = GenericForeignKey('content_type', 'object_id') def movements(self): movements = InventoryMovement.objects.filter(inventory_item=self) return sorted(movements, key=lambda x: x.datetime_entered, reverse=True) def completed_movements(self): movements = InventoryMovement.objects.filter(inventory_item=self, datetime_completed__isnull=False) return sorted(movements, key=lambda x: x.datetime_completed, reverse=True) def current_location(self): movements = self.completed_movements() if movements: last_movement = movements[0] loc = InventoryAddress( warehouse=last_movement.warehouse, location=last_movement.location, sublocation=last_movement.sublocation ) else: loc = InventoryAddress( warehouse='EXT', location=None, sublocation=None, ) return loc def current_warehouse(self): return self.current_location().warehouse class InventoryMovement(models.Model): movement_id = models.CharField(max_length=20, unique=True, blank=False, null=False, verbose_name='Movement ID') warehouse = models.CharField(max_length=40, null=False, blank=False, choices=warehouse_location_choices, verbose_name='Warehouse') location = models.CharField(max_length=40, null=False, blank=False, verbose_name='Target Bin') sublocation = models.CharField(max_length=40, null=False, blank=False, verbose_name='Target Position') inventory_item = models.ForeignKey(InventoryItem, null=True, on_delete=models.PROTECT, verbose_name="Inventory … -
Django parse JSON structure into Q filters
I have an input JSON structure that defines a set of logic that should be applied to a queryset. The json structure looks like this: filters = { "and": { "field__ismissing": "some_text", "other_field__gt": 100, }, "or": { "field__ismissing": "some_text", "other_field__gt": 100, } } which should parse into the following filter. (Q(field__ismissing='some_text') & Q(other_field__gt=100)) | (Q(field__ismissing='some_text') & Q(other_field__gt=100)) Is it possible to parse the JSON as such? The end goal would be to do something like Model.objects.filter(**filter_function(a, b, c)) -
How to increment database row by 1 for every time a link is clicked?
Currently every time I click on a product link on the website the entire database column "views" increases by 1 where as I need it so that just the row increases by 1.

Django perform_update not updating entry
I have a few generic DRF API views: class PageCreateView(generics.CreateAPIView): queryset = Page.objects.all() serializer_class = PageSerializer def perform_create(self, serializer): text = self.request.data.get("text") json = generate_json(text) calculated_level = level_calculate(json) serializer.save(json=json, calculated_level=calculated_level) instance = super().perform_create(serializer) class PageView(generics.RetrieveUpdateDestroyAPIView): queryset = Page.objects.select_related().all() serializer_class = PageSerializer def perform_update(self, serializer): text = self.request.data.get("text") json = generate_json(text) calculated_level = level_calculate(json) serializer.save(json=json, calculated_level=calculated_level) instance = super().perform_update(serializer) The perform_create works perfectly. However the perform_update does not seem to. Should I be doing something differently with the instance or the self object so that it updates the object in question? Generating JSON and calculating the level are both metadata that are dependent on, but which I do not want to include in the POST or PUT request. They need to be re-calculated/re-generated on each save. -

How to integrate django, firebase and android for custom authentication?
I am using firebase first time for push notifications. While going through various info I assumed that I may have to use custom authentication to generate unique IDs and send notification to the users using app. Now all processes adding confusion in my mind. My app accepts mobile no and password as login credentials and they are stored in backend our own server configured in django. I am making calls to server apis using retrofit. Now, I want to send a notification after one user completes certain process and it will be informed to another user using notification. I don't know unique firebase device ID of the another user but I know mobile number through backend dB. So how should I send message to server to get another users unique ID and send notification to that user using firebase dynamic dB? Appreciate step by step guidance. Regards, Pd -
Setting up Inlines in Django for a model that has foreign keys to multiple models

Django & React CORS error - will allow GET requests but not POST
I have created an app using django for the backend and react for the frontend (structured within a django app). Hence there are CORS requests. I have added installed CORS for django and added the following to the settings: CORS_ALLOWED_ORIGINS = [ "http://localhost:8000", "http://127.0.0.1:8000", ] However, when I can make REST requests from react using the prefix "http://localhost:8000", I get the error 403 forbidden. For instance, it will let me login but when logging out I get a 403 forbidden error. I can make GET requests fine and when I tested the API using an external tool like Postman there are no issues. Please advise. -

Refactoring Django model setup advice

Sample of current models.py with lots of repetition Sample of current forms.py with lots of repetition Current Front-End How can I re-create the formset above with less code? Here's what I'm trying so far but I've come across some issues I can't find a solution to. Any advice would be appreciated. #models.py class ReportCard(models.Model): PROGRESS_INDICATOR = [ ('1', '1'), ('2', '2'), ('3', '3'), ('4', '4'), ('NA', 'NA') ] student_perm_number = models.CharField(max_length=51, default='123456789') reporting_year = models.CharField(max_length=10, default='2020-2021') # Grade Received each Trimester standard = models.ForeignKey('reportforms.Standard', on_delete=models.CASCADE, null=True) t1 = models.CharField(choices=PROGRESS_INDICATOR, max_length=3, blank=True, null=True) t2 = models.CharField(choices=PROGRESS_INDICATOR, max_length=3, blank=True, null=True) t3 = models.CharField(choices=PROGRESS_INDICATOR, max_length=3, blank=True, null=True) # Math, Language Arts etc... class Domain(models.Model): name = models.CharField(max_length=100, blank=False) grade = models.ForeignKey(Grade, on_delete=models.CASCADE, blank=True, null=True) # Shapes, Geometry etc... class Standard(models.Model): domain = models.ForeignKey('reportforms.Domain', on_delete=models.CASCADE, blank=True, null=True) name = models.CharField(max_length=100, blank=False, null=True) The form is pretty simple #forms.py class ReportCardForm(ReportCardForm): class Meta: model = … -
How to restrict Endpoint
I am creating a multi-vendor marketplace with django. I have an endpoint for retrieving, updating and deleting a product that belongs to a store like this: localhost:8000/name-of-store/int:product_id. Note: "name-of-code" is the slug of the store. This is the code below: class EditItemAPIView(generics.RetrieveUpdateDestroyAPIView): serializer_class = ItemSerializer permission_classes = (IsAuthenticated,) def get_queryset(self): item = Item.objects.filter(pk=self.kwargs['pk']) print(item) return item With this code, if I append the id of a product that does not belong to a particular store in the url above i.e I do localhost:8000/name-of-store/5, where 5 is the id of a product that belongs to another store, it gets the product. How do I implement some kind of restriction such that if I try append the id of a product not belonging to the shop whose slug is in the url I get a 401 message? Any help will be greatly appreciated.
