order_with_respect_to ???

Hi everybody

I must be a bit dumb, but I fail to understand the doc for
the
"order_with_respect_to" META option... Could
someone be kind enough to
have mercy and take time to explain slowly ?

TIA

I've been wondering about it too, and this is what I've
found out:
- used on the "many" side of relations
- adds an _order integer field to the model
- automatically numbers objects' _order
- shows objects ordered by _order in admin
- is supposed to use fancy javascript
  to enable re-arranging objects in admin

ok

Woops ! Not documented ???

Seems fine

> - shows objects ordered by _order in admin

What I saw in admin was some strange boxes at more or less
random
locations (but this was with an edit_inline... err, perhaps
it's not
supposed to be used with edit_inline ???)

Would be fine, but doesn't seems to work here (django 0.91,
postgres
8.1.x, mozilla Linux x86_64; en-US; rv:1.7.12)

Thanks akaihola, I'll explore this in depth later.
