Django - pass a list of results when querying using filter
In my FollowingPageView function, I'm trying to filter posts based on the logged in user's list of user's he/she is following. You'll see the Profile model has a "following" field that captures the names of users the Profile owner is following. What I'm trying to do in my view is capture these names of the users in "following" then pass them to Post.objects.filter(created_by=user_list), but I will only get the last user in that list in this case. How can I iterate over the "user_list" Queryset and pass that to Post.objects.filter in order to return the posts from each user in that list? In this case, I should have two users in the Queryset [<User: winter>, <User: daisy>]. models.py class Profile(models.Model): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) bio = models.TextField(null=True, blank=True) website = models.CharField(max_length=225, null=True, blank=True) follower = models.ManyToManyField(User, blank=True, related_name="followed_user") # user following this profile following = models.ManyToManyField(User, blank=True, related_name="following_user") # profile user that follows this profile def __str__(self): return f"{self.user}'s' profile id is {self.id}" def following_users(self): for username in self.following: return username def get_absolute_url(self): return reverse("network:profile-detail", args=[str(self.id)]) class Post(models.Model): created_by = models.ForeignKey(User, on_delete=models.CASCADE) subject = models.CharField(max_length=50) body = models.TextField(max_length=1000) timestamp = models.DateTimeField(auto_now_add=True) likes = models.ManyToManyField(User, blank=True, related_name="posts") def __str__(self): return … -

Is it possible to create a dynamic form (add new fields in runtime) with CreateView in Django?
I'm building a form that allows the user to add the different features of a product, and I also want it to be a dynamic form so the user can put whatever categories he want in it. Something like, Form: Name: shirt Description: ... Categorie1: Color: Red Categorie2: Sleeve: short Categorie3: ... Add new categorie Save The problem is that I'm using CreateView for this page and don't know how to convert my form into a dynamic one. There's a way for doing this? or it's better to make it with a function view instead of CreateView? Here's my code, view: class ProductCreateView(CreateView): template_name = "product_create.html" form_class = ProductModelForm queryset = Product.objects.all() def form_valid(self, form): return super().form_valid(form) model: class Product(models.Model): title = models.CharField(max_length = 120) description = models.TextField() image = models.FileField(upload_to="products/images/") price = models.IntegerField() active = models.BooleanField(default = True) categorie = models.CharField(max_lenght = 50, default = '') def get_absolute_url(self): return reverse("products:product-detail", kwargs={"id": self.id}) def delete(self, *args, **kwargs): self.image.delete() super().delete(*args,**kwargs) form: class ProductModelForm(forms.ModelForm): class Meta: model = Product fields = [ 'title', 'description', 'image', 'price', 'active', 'categorie' ] Thank you in advance! -

Template results of modelformset_factory to separate forms:
When I use modelformset_factory it renders a page with all fields together and with the same name. However, I'd like to have each repeated form with a different title. This is how my page looks when the form is repeated two times (the form has three fields): Instead, I'd like it to look like this (sorry for the shabby edit): So, the idea is to create a "box" per form set with a title that changes depending on the number of form sets used. The code of this app: views from django.shortcuts import render from django.shortcuts import redirect from parameters.models import Parameters from .forms import RawAttributesForm from .models import Attributes from django.forms import modelformset_factory #modelformset dependiendo del número de atributos def attributes_create_view(request): param = Parameters.objects.latest('id') atrib = modelformset_factory(Attributes, fields=('attribute_code', 'attribute_name', 'attribute_levels'), extra=param.atr_n, widgets={}) form = atrib(queryset=Attributes.objects.none()) if request.method == "POST": form_atrib = form(request.POST, request.FILES) print(form_atrib) if form_atrib.is_valid(): form_atrib.save() return redirect('../home') context = { "param" : param, "form": form } return render(request, "atrib_set.html", context) models from django.db import models # Create your models here. class Attributes(models.Model): attribute_code = models.IntegerField(default=None) attribute_name = models.CharField(max_length=50) attribute_levels = models.IntegerField(default=None) forms from django import forms from .models import Attributes from extra_views import FormSetView from django.utils.translation import … -

Generic Formset with M2M Field not saving Entry correctly

Uploading multiple webcam images to Django servers
I am creating a form, which takes the following data from the user: 'name', 'email', 'mobile_no', 'photo', 'id_proof'. Out of these, the simple text type data can easily be sent over the network to the server using POST method.However, the fields, photo and id_proof will be uploading images, and these images will be captured by the webcam of the user. A normal Form could be used, but the problem is that 1 page can have n number of such forms.Eg. if a page has 4 forms of such type, there will be 8 images to be uploaded. Hence, I can't even send the data over the server and then convert it to a file, as it will simply reduce the efficiency of the system as n increases.How can I convert the images into a file, and then send it over so that my Django application saves these images? I referred to this question: How to send captured webcam image and save to server via input field, but this provides solution only for sending a single image file and nothing else. -
