#36337: Broken autocomplete inside Inline after clicking "Add another ..."
-------------------------------------+-------------------------------------
Reporter: Michał Pokusa | Type: Bug
Status: new | Component:

Version: 5.2 | Severity: Normal

This error occurs on versions from 3.2 (or even before, untested) up to
latest (5.2 at this time). It seems like it is only JS/CSS related.
Happens with both `TabularInline` and `StackedInline`.

Possibly related to #36336.

Tested on Google Chrome, Firefox, Edge and on mobile device.

Steps to reproduce (code below):
1. Go to change form view (editing existing object, adding new one,
doesn't matter)
2. Click "X" on any inline except last one
3. Click "Add another ..." once again

tickets/refs/heads/main/36337/2025-04-19%2012%2016%2000.png)]]

Code:
== models.py
{{{#!python
from django.db import models

class Restaurant(models.Model):
name = models.CharField(max_length=100)
address = models.CharField(max_length=255)

def __str__(self):
return self.name

class Order(models.Model):
restaurant = models.ForeignKey(Restaurant, on_delete=models.CASCADE)
order_number = models.CharField(max_length=20)
products = models.ManyToManyField("Product", related_name="orders")

def __str__(self):
return f"Order {self.pk} from {self.restaurant.name}"

class Product(models.Model):
name = models.CharField(max_length=100)
price = models.DecimalField(max_digits=10, decimal_places=2)

def __str__(self):
return f"{self.name} - ${self.price}"
}}}

== admin.py
{{{#!python
from django.contrib import admin

from .models import Restaurant, Order, Product

class OrderInline(admin.StackedInline):
model = Order
extra = 3

fields = ["order_number", "products"]
autocomplete_fields = ["products"]

@admin.register(Restaurant)
class RestaurantAdmin(admin.ModelAdmin):
list_display = ("name", "address")
search_fields = ("name", "address")

inlines = [OrderInline]

@admin.register(Order)
class OrderAdmin(admin.ModelAdmin):
list_display = ("restaurant", "order_number")

@admin.register(Product)
class ProductAdmin(admin.ModelAdmin):
list_display = ("name", "price")

search_fields = ("name",)
}}}
