I am getting an error when I try to `migrate`. I have added lots of unique contraints and I'm not sure which one I haven't migrated yet.

```
django.db.utils.IntegrityError: (1062, "Duplicate entry '16-' for key 'mainapp_caption_photo_id_1e4a8c0d_uniq'")

```

How do I view what is being ran in `migrate` so I can inspect the IntegrityError myself and fix the duplicate entries? I want to see what unique key is trying to be placed.
