Hi, I need some pointers around ajax
while trying to select an option on the components I've published on the template I've got a 404 response from the JS script.
I don't have enough knowledge to identify and debug the JS script myself any pointer for this problem would be greatly appreciated.

my code so far:

app's views.py

from django.views.generic.base import TemplateView 

class ProductDetailView(TemplateView):
   template_name = 'product/product_detail.html'

components.py

from django_unicorn.components import UnicornView
from django.http.request import HttpRequest as request 
from django.db.models import Q
from django.shortcuts import get_object_or_404, get_list_or_404

from navigation.models import *
from inventory.models import *

class ProductDetailView(UnicornView):
    
    selected_finition= ""
    selected_size= ""
    
    def get_context_data(self, *args, **kwargs):
        context = super(ProductDetailView, self).get_context_data(**kwargs)
        #grab the slug in path to instantiate query with 
        obj = get_object_or_404(Product, slug = self.request.get_full_path().split('/')[-2])

        #print(f"product detail value data: {type(obj)}")

        detail = get_list_or_404(ProductDetail, SKU__startswith=obj.SKU)
        #print(f"product detail data: {detail}")
        context['obj'] = obj
        try:
            context['finition'] = ProductAttributeFinition.objects.filter(Q(SKU_id__in=detail)).distinct('name')

        except:
            return context['finition']
        #print(f"dfinition detail :\n {context['finition']}")
        try:
            context['size'] = ProductAttributeSize.objects.filter(Q(SKU_id__in=detail)).distinct('value')

        except :
            return context['size']
        #print(f"detail-size :\n {context['size']}")

        context['price'] = ProductDetailPrice.objects.filter(Q(SKU_id__in=detail))
        #print(f"detail-price :\n {context['price']}")

        return context

Everything that posted looks like it is correct, but I wonder if having duplicate ProductDetailView classes is causing issues. Can you try renaming one of them to see what happens?

Thank you for your reply!
I tried what you suggested and renamed the class and the respected unicorn's file and it still returns 404, however, I also tried to put my get_context_data() in the app's view and got a response but the template after the POST returns an empty page which is natural since the components now don't have a context to process... following up that idea I also tried to put the context on the components but came back to a 404.
I also downgrade Django from 4.0 to 3.2 just to be sure.

I believe at the moment I should go to the hooks available in the UnicornView to force rendering the context after the data get fetched but I lack the understanding

I update this thread once I got something.
