django admin show related object inline (self referencing)

Question

I have a self referencing model like this:

class Item(models.model):
      parent = models.ForeignKey('Item',null=True,blank=True)
      field = models.CharField(max_length=100)

And I want to display the hierarchy in the admin, to do so I do:

class ItemInline(admin.TabularInline):
    model = Item
    can_delete = False

class ItemAdmin(admin.ModelAdmin):
      inlines = (ItemInline,)

admin.site.register(Item, ItemAdmin)

However it does not work , when I try to acces an item in the admin it hangs endlessly but it I can access the list of items just fine. However when I remove the inline it works fine.

Answer 1

Ok the issue i was facing was due to the fact I tried to display the whole object , by restricting the fields displayed it worked. I did it like this : Django - Excluding some fields in Inline Admin Interface
