Annotate queryset with count of instances related to it in another queryset
I have three related models like so: Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE ) city = models.ForeignKey(City, on_delete=models.SET_NULL, null=True) Product(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) price = models.FloatField() geo_location = models.PointField(srid=4326, null=True, blank=True) City(models.Model): name = models.CharField(max_length=75) geom = models.MultiPolygonField(srid=4326) the related city can be retrieved from the geo_location field if specified example : city = City.objects.get(geom__contains=someproduct.geo_location) or from the owner's profile : city = someproduct.owner.profile.city lets suppose i have a these queries: all_cities = City.objects.all() products = Product.objects.filter(price__lt=2500) what i want to achieve is products_count attribute on each instance of the all_cities queryset from products queryset maybe a loop would solve this but don't know how to implement it and there might be another solution using Subquery and OuterRef -
how to serve webp from a variable in a static tag wagtail 2.5
I made a carousel orderable. each instance has an image and char field for the webp file name through the picture element. The webp image loads perfect when I hard code the srcset instead of using a {{variable}}. Problem is that keeps the admin backend from being dynamic and leaves me hard coding every pic on the site or just the pages I want to rank for on google. Ive read a bunch of other posts but im still stuck. is there any way to serve webp filename cleanly from the backend? I have read. load static file with variable name in django django 1.5 - How to use variables inside static tag This one was the closest to solving my problem but falls short. https://snakeycode.wordpress.com/2015/02/20/variables-in-django-static-tags/ carousel orderable fields carousel_image = models.ForeignKey("wagtailimages.Image", on_delete=models.SET_NULL,related_name="+",) webp = models.CharField(max_length=100, blank=True, null=True) home template carousel {% for loop_cycle in self.carousel_images.all %} {% image loop_cycle.carousel_image max-750x500 as img %} <picture> <source srcset="{% static '{{loop_cycle.webp}}'%}" type="image/webp" > <img src="{% static '{{img.url}}'%}" alt="{{ img.alt }}"> </picture> As this works perfect when I hard code but then whats the point of having a carousel with an orderable that is next-gen image friendly?

How do I pass a variable from views to a base html template using Django
I have a floatbar with contact details that shows only when the website is opened on a mobile screen. However, there are pages where I do not want them to appear, and I figured I can pass this through context in the respective view classes. What I need to figure out is how do I access this in my base template where this floatbar is called. I did read a bit about context processors, but I am not sure if I can change the value of the variable being passed. I would like to be able to access the variable in base html, but also change the value stored within views.py -
How to deploy django app on hosting service
I'm new to web development. I bought the web hosting start-up package from Siteground to host my graphic design portfolio website. It's a simple Django app that is a one-page portfolio with a contact form using Django's sendEmail through gmail service. I've never deployed a Django app, let alone my own website. I've only made and deployed a Wordpress website which is pretty self-explanatory. I understand how to upload my website to the server through FTP, but I have no idea how to configure the Django app for deployment (aside the brief explanation in their docs) or how to connect the app to my server to run on the domain. I think I'm supposed to configure something in wsgi, but I don't really understand how that works and I can't find support anywhere on deploying a Django app on Siteground (or something like it) even though they have python support. I connected to Sitegrounds' SSH to follow some tutorials on Django deployment, but even though it's Unix I can't use (or don't understand how to) sudo apt-get to follow the tutorials. Here is my settings.py: import os with open('cfsite/key.txt') as f: SECRET_KEY = f.read().strip() # Build paths inside the project … -

What I want to do is to choose from those fields to fill-out my form which is connected to 'DocDetails' model. my form used on my views is using the model 'DocDetails'. I would like to access chassis.name, chassis.board (all items) and chassis.fa fields in my template, so I can display them in my html page. so far I can only access chassis.name by doing: {{ form.chassis.value }} but I cannot access other fields typing similar template tags. is there a way to do this? -
Why will my profile pictures not show up Django
So I am creating a small website, and I want users to be able to upload profile pictures to their page. However, I ran into a problem, and the image won't render. I have the actual process for the user to upload a profile picture, and it saves to a directory, but it won't load in the HTML document I have looked online for answers, but have found none. I have tried renaming fields in the models.py file because I thought that it might be an issue where I need a certain field name.

How to make a ManyToMany serialization to be able to create a object in the POST request?
I'm trying to create a serialize to handle a ManyToMany relation, but it's not working. I have read the documentation and I probably doing something wrong. Also I have read the answers here.

"Unknown column in having clause" when using a SimpleFilter on Django admin
I'm using a simple filter to filter model results on Django Admin. Even though all the queries are tested and working well, the code keeps throwing an error. I think it may be a bug.

DRF tries updating read-only fields
I have a Django model (derived from the CleanerVersion Versionable model) which I am serializing using DRF and I want several fields set to read only (they are created by a series of functions and are therefore set as properties), however when I try to update the record, the read-only fields are included in the validated_data, and are also included in the procedure which sets the attribute and the value during the update(). My model.py class Athlete(Versionable): ... @property def photo_status(self): if(self.photo!=None): return True return False ... For my serializer.py I tried different approaches: Setting the serializer field to read-only class AthleteSerializerSerializer(serializers.ModelSerializer):: ... photo_status= serializers.BooleanField(read_only=True) ... class Meta: model = Athlete fields = '__all__' ... Excluding the field class AthleteSerializer(serializers.ModelSerializer):: ... class Meta: model = Athlete exclude = ['photo_status'] ... Added the extra kwargs class AthleteSerializerSerializer(serializers.ModelSerializer):: ... class Meta: model = Athlete fields='__all__' extra_kwargs = { 'photo_status': {'read_only': True}, } ... and no matter what, when I run: serializer = AthleteSerializer(Athlete.objects.current.get(identity=a.identity),data=request.data.get("athlete")) serializer.is_valid() serializer.save() I get the following error message setattr(instance, attr, value) AttributeError: can't set attribute I set several different properties to read only, as well as a few field (e.g. CleanerVersion automatically updates the id and identity fields so … -
Dealing with varying child levels in Django models
So I've got a database that has an incomplete hierarchy and I'm not quite sure how to deal with it. For example, I want to measure the mass of species.. Each family can have multiple geneses. Each genus can have multiple species. However, not ALL species have a sub-species (with sub-species being the lowest level). In other words, the endpoint of the hierarchy could be subspecies OR species. The solution I have come up with doesn't seem to follow good principles. class mass(model.Models): name = models.CharField(max_length=100) value = models.NumericField() family = models.ForeignKey(family) genus = models.ForeignKey(genus) species = models.ForeignKey(species) subspecies = models.ForeignKey(subspecies) # Could be a blank field class family(model.Models): name = models.CharField(max_length=100) class genus(model.Models): name = models.CharField(max_length=100) family = models.ForeignKey(family) class species(model.Models): name = models.CharField(max_length=100) genus = models.ForeignKey(genus) class subspecies(model.Models): name = models.CharField(max_length=100) species = models.ForeignKey(species) -

Django: cannot delete formset forms (Javascript on the frontend)
I have a basic invoice application and, in the single invoice update view, it is possible to add and remove elements of the invoice. Adding them works, unfortunately it does not in removing them.

(Django) Dynamically adding custom form to Inline admin
CONTEXT I'm building my personal website, and wanted to handle database translation. While django-apps already exist for it, I thought it'd be fun and interesting to build my own translation package. I'm currently at the last step, which is showing the Translation instances directly into the object's admin STRUCTURE What you need to know about the database is that I have the following tables/models: My models that have fields which require translations: Job, Type, Article, etc. Language (list of available languages) Item (equivalent to saying "the NAME field from the JOB model, instance 33" Translations (Many to many with Language and Item) As for the relationships that matter to us: Job, Type, and Article all have ForeignKeys to Item Note that they can have SEVERAL ForeignKey (if they have several fields that need translating) Item has a GenericForeignKey to store Job, Type, and Article instances Translation has a ForeignKey to Item WHAT I'M TRYING TO DO In the admin, in the Type (or Job, or Article) detail view, I'd like to directly display the Translation instances related to its object (Type--> Item --> Translation). It's basically like a nested inline, but I only display the last level. That way, I … -

How to pass extra context to Django inline formset template
