How to limit choice field options based on another choice field in django admin

Question

I have the following models:

class Category(models.Model):
    name = models.CharField(max_length=40)

class Item(models.Model):
    name = models.CharField(         


        

Answer 1

Here is some javascript (JQuery based) to change the item option values when category changes:

You need a view to be called on the /items/ URL that supplies a JSON list of the valid items.

You can hook this into your admin by using model admin media definitions.
