AttributeError: 'function' object has no attribute 'as_view'

Using Django Mystery Errors
1

I am trying to create a class-based view for SellerOrderListView.

in seller_views.py i defined the view as

class SellerOrderListView(ListView):
    model = SellerOrder  # Use the SellerOrder model
    template_name = 'seller/seller_orders_list.html'  # Create the template for the seller order list
    context_object_name = 'seller_orders'

in app urls.py, import statement is: from AfriExportingapp.seller_views import SellerOrderListView

url pattern is: path('seller/orders/', SellerOrderListView.as_view(), name='seller_orders'),

yet, i get this while running migrations:

When posting code or error messages here, please surround the code (or error message) between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. (I’ve taken the liberty of updating your original post.) Single line code fragments can be surrounded by single backtick characters.

Please post your complete seller_views.py file. Either something isn’t quite as you have described here, or there’s something else in that file causing problems.

Hi Supremebosslife,
Based on the error message you received, it seems your SellerOrderListView class is being treated as a function. I can think of 3 possible reasons:

  1. Check if you have applied a decorator to your SellerOrderListView class in seller_views.py which isn’t visible in the code you provided. Some decorators like @login_required are meant to be used for function based views and returns a function.
@login_required
class SellerOrderListView(ListView):
    model = SellerOrder  # Use the SellerOrder model
    template_name = 'seller/seller_orders_list.html'  # Create the template for the seller order list
    context_object_name = 'seller_orders'
  1. You may have accidentally created a function with name “ListView” somewhere in your seller_views.py
def ListView():
    #function based view code
  1. Check your ListView import.It should be
from django.views.generic.list import ListView
