Yep, works a treat (and was definitely failing without it, same error as before) -- certainly item 1), I haven't checked 2) very carefully, but I'm pretty sure my migration script would have thrown duplicate key errors if things hadn't been deleted properly. I consider that a fairly good stress test of deleting in general, and the chunking you just added. The models in my app are highly interrelated with foreign keys everwhere (often multiple to the same table etc). The only thing it doesn't include is one-to-one relations, since I didn't manage to get them to work when I was building the models (though I could have used them). Of course, with problems like stack limits I was encountering, you can't guarantee it will work for larger volumes of data, because it will depend on the size of 'many' in 'many-to-one', but for day-to-day usage it should be more than adequate. For the bulk migration I was doing, you would be much better writing some custom SQL, but I was feeling lazy so wrote it in Python.
