num_in_admin problem in tutorial

[bretthoerner@…]

It seems that when I changed the poll admin page to include the choices with num_in_admin=3, it didn't display 3 for existing polls.

Existing polls only show 1 new row more than the number of choices I already had. In other words, if my poll has no choices, it shows 1 blank row. If I had one choice, it shows one blank row after that (2 total), if I had 2 choices, it shows 1 blank row (3 total)... after that it's moot because num_in_admin=3 is fulfilled.

Here's an image showing my code vs what I got,

It should be noted that if I went to "Add New Poll", it would have 3 new empty choice slots, it just doesn't seem to work for existing polls...?

(I'm not sure if this would be 1.1 or what but I'm using svn-r844)

This is, currently, expected behaviour AFAIK.

The current plan (AFAIK) is to make this all use explicit add/delete behaviour soon after the new-admin branch lands ( and get rid of the concept of core fields, etc). Num_in_admin would go at the same time.

So maybe this is a duplicate of #13.

Yes, this is expected behavior. By default, when you go to a change page, Django gives you one empty extra row for edit_inline objects. Use num_extra_on_change to change this from 1 (the default) to whatever number you want. See ​http://www.djangoproject.com/documentation/model_api/#admin-options for the full scoop.
