What is best practice for organizing Django REST Framework serializers?
I am working on migrating a legacy REST api to Django REST framework. Many responses from contain nested serializers, for example: class TemplateSerializer(serializers.ModelSerializer): colors = ColorSerializer(read_only=True, many=True) fonts = FontSerializer(read_only=True, many=True) property_ids = serializers.PrimaryKeyRelatedField(many=True, queryset=Property.objects.all()) ... class Meta: model = Template fields = '__all__' class ColorSerializer(serializers.ModelSerializer): swatch = SwatchSerializer(read_only=True) class Meta: model = Color fields = '__all__' # and so forth, just imagine several serializers with fields that are read only or write only etc Currently I was have all serializers in my_app/serializers.py and the serializers.py file has grown way too large and disorganized. In that file, a django model usually has several versions of serializers, for example, the list view method may have a different serializer than retrieve and create may have a different serializer than update, etc. So a single ViewSet may have 4-5 different serializers. Also, the nested serializers, like the ColorSerializer above, may have different versions based on requirements of the response when its nested in another serializer versus when GET /colors endpoint is called. With that being said, I want to start organizing/refactoring things for readability to try to be more DRY. I'm aware the API is poorly designed, but redesigning is not an option … -
How to remove from django sitemap pagination ?p=(1,2,3...n)
Okay we have a lot of pages. So when the content pages spill over 400 is created next page for sitemap and it looks like that - sitemap-instructions.xml?p=5 The problem is that pagination is conflicted with robots.txt where we have restrictions for many things including pagination pages.

Querying Django Models linked by a Foreign Key to get a complete Query set, counting liked posts
This is a CS50 Pset - Network - I'm battling my way through this and all but this bit is finished I think I have trapped myself into a corner, I have 4 different Models, 3 are related to this question, User, Posts and LikeMatrix. LikeMatrix uses a Foreign key to both the User Model (user) and the Posts Model (post), its a matrix recording what user liked what post as I couldn't get my original idea to work with a many to many link between User and Posts Models. (if I did it all again I would do it different). I have my Js working, my API's working, evrything else working except the last piece of the puzzle, to count the likes per post in the LikeMatrix Model and then send it to index.html I run a query in views.py that extracts the data from Posts and sends it in a template/Queryset to index.html, see screen shot below for what it looks like on the screen. Im sure there are a lot more professional ways to do what I'm doing but I'm learning as I go and doing it solo, this has taken me weeks already...... Any advice on … -

How to get 1 list when using django queries with a M2M relationship
This question is very similar(if not the same to): Django query — how to get list of dictionaries with M2M relation? . I am just asking this question to be able to learn if there has been any improvements to djagno that include functionality for this since 11 yrs ago I have a M2M relationship: class RandomObject(models.Model): name = models.CharField(max_length=50,blank=False) description = models.TextField(blank=False) features = models.ManyToManyField('Features',blank=False,db_table='RandomObjectFeatures') class Features(models.Model): LIGHTING = "LIT" SECURE = "SGE" COVERED ="CVP" FEATURE_NAME_CHOICES = [ (LIGHTING,"Lighting"), (SECURE,"Secured Well"), (COVERED,"Covered"), ] feature_name = models.CharField(max_length=3,choices=FEATURE_NAME_CHOICES,blank=False,null=True) def __str__(self): for code, display_name in self.FEATURE_NAME_CHOICES: if self.feature_name == code: return display_name return self.feature_name I have populated the database and now want to query the database to be able to show the features of a randomObject in a template random_objects_data = random_objects.values('name','features__feature_name') Now when I print this I get the following: (I have truncated it as it is long, but it makes the point) {'name': 'object1', 'features__feature_name': 'SGE'}, {'name': 'object1', 'features__feature_name': 'LIT'},{'name': 'object1', 'features__feature_name': 'CVP'} This is unhelpful as objects not in the database are created. I would like to get (or something similar to): {'name': 'object1', 'features__feature_name': ['SGE','LIT','CVP']} This means in the template I can iterate though each feature in features__feature_name. … -

Django model relations - "Owning" a related model enforced at the model level
I'm not really sure how to title this question, so forgive my title's ambiguity. I have two models, Customer and Address. Each has typical fields you would infer from their model names. Address is also set as an inline to Customer in admin.py: class Customer(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) email = models.EmailField(unique=True) phone = models.CharField(max_length=15, blank=True) def __str__(self): return f"{self.first_name} {self.last_name}" class Address(models.Model): customer = models.ForeignKey(Customer, on_delete=models.CASCADE) street = models.CharField(max_length=100) street_additional = models.CharField(max_length=100, blank=True) city = models.CharField(max_length=50) state = models.CharField(choices=US_STATES) zip = models.CharField(max_length=5) def __str__(self): return self.street I want to add a billing_address and shipping_address to the Customer model to allow a customer to choose one of several saved addresses to be used as those types of addresses accordingly, but I don't want any customer to be able to choose any address. My initial plan was to model the Customer with a foreign key relation back to Address while using limit_choices_to such as: class Customer(models.Model): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) email = models.EmailField(unique=True) phone = models.CharField(max_length=15, blank=True) billing_address = models.ForeignKey("Address", on_delete=models.SET_NULL, related_name='billing_address', blank=True, null=True, limit_choices_to={'customer_id':some_callable()) shipping_address = models.ForeignKey("Address", on_delete=models.SET_NULL, related_name='shipping_address', blank=True, null=True, limit_choices_to={'customer_id':some_callable()) def __str__(self): return f"{self.first_name} {self.last_name}" I realized this is not how limit_choices_to is intended … -

How can I setup Django to serve files on a file server?
I am working on a Django website where files are going to be sold. These files can be large in size, up to 5GB. So, I believe that in addition to a VPS for serving the website, I also need to set up a file server (download server). First of all, since I haven't used download servers before, I'm unsure about how to connect the download server to the VPS that hosts my website. In my research, I've come across the idea of setting up a subdomain. For instance, if my website is mywebsite.com, I would create a new DNS A record, like dl.mywebsite.com, and then use this link to serve the files to users on my website. Is this a correct approach? And also what protocol should be used for this connection when a user clicks a download button? Is it going to be a file protocol, HTTP, FTP, or something else? Another question is that I have no idea how to configure my Django project to provide download links to users who have purchased a file when the files are located on another server. For example, how do I configure the media root and URL so that the … -
how to pass queryset or kwarg to RangeFilter class in Django filters
I'm working on a Django-driven website which uses django-filters and, specifically, RangeFilter to show price diapason of the real estate properties and visualize it as a slider on search form. My queryset is initially formed in the PropertyListView as a list of objects with a certain status (sale or rent), and then it is being passed to the filter, PropertyFilter. The PropertyFilter uses several other classes to construct corresponding widgets, such as slider for the price: class PropertyFilter(FilterSet): price = PriceFilter() ... class PriceFilter(RangeFilter): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) values = [p.price for p in Property.objects.all()] min_value = min(values) max_value = max(values) self.extra['widget'] = CustomRangeWidget(attrs={'label':_('Price, €'),'data-range_min':min_value,'data-range_max':max_value}) The problem is that the PriceFilter does not "know", which objects are in the queryset, and takes the price diapason from the full list of objects. This results in awkward slider, whose diapason is too wide, from 600 to 300,000 euro, which is irrelevant. I want to make the PriceFilter to get prices from the queryset. How it is possible to do it? I've tried to use queryset directly inside this filter, to pass the queryset into it, or to pass the status as a kwarg parameter, but every time I got an … -

Syncing issue within Socket IO
I've implemented a website chat with python-socketio and socket.io-client. At times, when we simultaneously open multiple tabs in different browsers or incognito sessions with the same logged-in user, the newly opened tabs can successfully send and receive messages. However, the older tabs do not send or receive messages, even though they remain connected to Python Socket.IO and socket.io-client. Additionally, I've already used a room session for managing the connections. This Problem happens on a live server where, at any point about 50-100 users are connected to the socket, not on localhost.

Using Django ORM to query a Model with two FKs that are related through an unique_together constraint on a third Model
I am currently facing a challenge in creating a QuerySet that accurately represents the relationships within my Django models. I have a model equipped with two foreign keys, FK1 and FK2. These two foreign keys, when combined, create a tuple representing a classification (FK1, FK2 -> CLS.pk). This relationship is managed and represented through another model, where I store the records corresponding to these foreign keys and the resulting classification (FK1, FK2, CLS.pk). Defining my question has been a challenge in itself, so I've tried to simplify the relationship to illustrate the core idea of what I'm attempting to achieve here. class Event(models.Model): value = models.DecimalField(decimal_places=2, max_digits=11, default=0.0) event_date = models.DateField() local = models.ForeignKey(Local, on_delete=models.CASCADE, related_name='event_set') origin = models.ForeignKey(Origin, on_delete=models.CASCADE, related_name='event_set') class Meta: db_table = 'db_event' class Local(models.Model): name = models.CharField(max_length=100, unique=True) class Meta: db_table = 'db_local' class Origin(models.Model): name = models.CharField(max_length=100, unique=True) class Meta: db_table = 'db_origin' class Classification(models.Model): name = models.CharField(max_length=100, unique=True) class Meta: db_table = 'db_classification' class ClassificationPerOriginAndLocal(models.Model): local = models.ForeignKey(Local, on_delete=models.CASCADE, related_name='classification_related_set') origin = models.ForeignKey(Origin, on_delete=models.CASCADE, related_name='classification_related_set') classification = models.ForeignKey(Classification, on_delete=models.CASCADE, related_name='classification_related_set') class Meta: db_table = 'db_classification_per_origin_and_local' unique_together = ('local', 'origin',) Consider an 'Event' Model designed to store records for events occurring at a specific origin … -

My first approach had been to trigger OTP generation when root logs in, root gets redirected to a waiting page.

I've created a model with postgis and rendered the templates with Folium. But when rendering the html. Geographic points appear in a geographic area that does not correspond.

How to fix in django "Page not found (404)" error ("Django tried these URL patterns... The empty path didn't match any of these.")
As a newbie to Django, I encountered the same problem as many before me. I would appreciate if you didn't mark my question as a double immediately because I checked the fixes those old posts suggested but to no avail, unfofrtunately. When I start server I get: Page not found (404). Using the URLconf defined in shops_online.urls, Django tried these URL patterns, in this order: admin/ api/organizations/ [name='organizations-list'] api/organizations/<int:id>/shops_file/ [name='get-shops-file'] api/shops/<int:id>/ [name='shop-view'] api/v1/token/ [name='token_obtain_pair'] api/v1/token/refresh/ [name='token_refresh'] api/v1/token/verify/ [name='token_verify'] docs/ [name='schema-swagger-ui'] The empty path didn’t match any of these.
